MDM Application Toolkit for Product Domain
I recently had to build a product bundling process for a demo using BPM and the MDM Application Toolkit(MDMAT). Having built many business processes over the past 2 years using data from InfoSphere MDM I realized this was going to be the first one I that I was to build against the product domain of the physical engine. Using the MDMAT against the Party domain is pretty darn easy and very quickly a rich process can be built that interacts with MDM's library of web services for many different types of processes. How useful would it be for me when operating against the Product Domain, especially when a good chunk of my data was stored in Product domain XML soft specs? Well I'm pleased to say it was also very straight forward. I've written some notes below that will hopefully allow others to also find it just as easy to use the MDMAT against the product domain.
The process was to execute a search against the MDM product domain using some pre defined criteria that would allow me to pull back all products that met a certain criteria. in this case it was to retrieve a list of products that were within the 'Mobile Phone' category of the 'Channels' hierarchy, were aimed at a 'Market Segment' that was 'Affluent' had an 'Effective Date' before today's date and an 'Expiry Date' that was after todays date. This would allow me to show currently active offers on the mobile channel for Affluent customers. The 'Market Segment', 'Effective Date' and 'Expiry Date' attributes were all stored as attributes within an XML spec called 'Offer Attributes'. In the search results that come back from MDM I also needed to pull out some additional attributes that were stored within another XML spec called 'Channel Mobile Phone', these attributes were named 'Mob
Whenever I build a business process I first start by defining the variables that I will need. Since BPM applications are data driven, I find it helpful to define the data upfront and then worry about wiring them into a process at a later stage. Using the MDM Workbench I exported my MDM WSDL and imported it into Process Designer. This gives me access to my MDM Product business objects within BPM, allowing me to easily construct a ProductSearchBobj object with the criteria I need to execute my search and also create a Prod
With the objects defined I could move on to define my process flow. I created a very simple flow to suit the requirements as seen below:
I would first use the 'Configure Spec Search Criteria' node to execute a script to populate the ProductSearch object with the crieteria I needed. I would then configure the 'Retrieve all Offers' node to use the MDM Application Toolkits' Physical MDM Txn service to execute a search an return a list of Prod
With my objects defined and my process defined all I had to do was a little bit of scripting to firstly populate my search and then extract my search results to populate my displayObject. (I had already populated my MDMConnection object with my MDM server's credentials and configured the 'Retrieve all Offers' node to use the MDM Application Toolkit's Physical MDM TXn service to call an MDM 'sea
Populating the Search
I wrote a simple script in my 'Configure Spec Search Criteria' object to pass in the search criteria. I wont include the full script here, but all I had to do was create an instance of a ProductSearch object and set the following attributes:
When passed into the 'Retrieve all Offers' node my search criteria successfully results in a list of products that I am interested in being returned as a list of Prod
Extracting the spec values and populating the display object
Up until now everything I had done was pretty similar to other processes I had built, this final piece was the most challenging, in that I had never extracted values from an XML spec before within a business process. Looking at my Prod
With my spec values now populated inside my Prod
This ended up being a bit of a longer blog post then I intended (sorry JT), but hopefully it will provide you a good starter in using the MDMAT for the product domain. I really enjoyed building this process (and writing this article) as it showed me how cool the MDMAT is for helping me to build MDM centric business processes. The ability to build processes against MDM and not worry about the connection and any complexity in calling MDM Web Services saves a huge amount of time and with a little bit of script I was able to leverage the value of MDM's XML specs. if you want more information drop me an email. I'd love to hear what you are doing.

No results found is a common response to a search request, but how do you detect this in your BPM process ?
A “No Results Found” situation causes an exception to be thrown which means you can detect it using an intermediate error event, but you need to be able to handle a real errors as well as a no results found which is a special kind of exception.
Here we have a simple example of a search human service which applies equally to Physical and Virtual MDM Server.
There is an intermediate error event attached to the do search nested service that calls the MDM Search integration service. The gateway decision determines whether it is a no results found or not.
To determine how to configure the decision gateway we need to have a look at the format of the exception we get when a no results found is generated and this differs slightly between virtual and physical MDM Server.
Handling a Virtual MDM Server response
A sample of part of the xml format of the exception is shown here
Here is is the reason code we are interested in. So the decision gateway configuration looks like this
The decision logic being
extracts the reason code and checks for ENOREC.
Handling Physical MDM Response
The implementation remains the same, the test within the decision gateway needs to be altered as the location of the reason code is different to virtual. In this example the reason code that is checked is applicable to a Party or Person Search, however it is possible that the reason code will be different for different types of physical search.
A sample of part of the xml format of the exception is shown here
Here we see the reason code we are interested in is nested under the <errors> tag within an < element>.

The alternative is to manually install the MDM Workbench for MDM configuration and development, and an Operational Server for test purposes. In this example I will install a full development and test environment on Windows, using a DB2 database. The instructions below assume that you do not have any of the prerequisite software installed but, if you do, just skip the relevant steps.

Installing Installation Manager
I ran install.exe to install Installation Manager in GUI mode. After installing Installation Manager you can add the required repositories individually before you run each install, as I did in the video series, or you can add all the repositories in one go as follows.
Create a repository.config file in the directory where you extracted the install images. Copy and paste in this content:
Edit any paths based on the directories you used before saving the file. Now you can add this single repository using the Installation Manager repository preferences and all the packages will show up on the install page.
For more information about Installation Manager, see the Inst
Note: you may have seen a suggestion to alter Installation Manager's agent data location using the cic.appDataLocation configuration setting, however it is not typically necessary, or a good idea, to change this setting.
Installing the workbench
Installing the workbench is straightforward once you've added the Rational Application Developer and workbench repositories to Installation Manager. Pick a suitable install location, for example C:\IBM\SDP, and you can accept the defaults for everything else.
In the MDM
Installing Operational Server prereqs
Before installing the MDM operational server, you need to install DB2 Enterprise Server Edition version 10.1 and WebSphere Application Server 126.96.36.199. In addition, the Installation Startup Toolkit provides the database scripts you'll need to create an MDM database.
You can watch how to run these installs in the MDM
Important: you must install DB2 in a directory called SQLLIB, otherwise the operational server install will not work. For example, I installed DB2 to C:\IBM\SQLLIB
I accepted most of the defaults in the DB2 install wizard, except that I chose not to enable email notifications or operating system security since this is for a development environment.
WebSphere Application Server and Installation Startup Toolkit
Both of these are installed using Installation Manager so I installed them at the same time. (You could even install them at the same time as the workbench to save time.)
Important: you must install fix pack 2 for WebSphere Application Server 8.5 otherwise the MDM install verification tests will fail.
I changed the install locations, to C:\IBM\AppServer and C:\I
Preparing to install the Operational Server
There are several advantages to manually installing a development and test environment, however the biggest disadvantage compared to a typical install is that the installer does not create an MDM database or WebSphere profile for you. Instead, you have to prep
These are the steps I followed, which are covered in the MDM
Edit SQL files
There are a couple of SQL files provided in the startup toolkit for creating an MDM database on DB2:
Both these files contain placeholders which need to be replaced with suitable values before use. These are the values I used:
Notes: Authority will be granted to the user specified by the <DBUSER> value, so this should be different to the user running the scripts. The database name is easy to specify in the installer but here I used the default. The tablespace names need to match the settings used by the installer, and the easiest way to do that for a development environment is to use the values shown above.
The following PowerShell command will fill in the placeholders and I ran it for CreateDB.sql and CreateTS.sql rather than editing the files by hand:
powershell -command "(Get-Content C:\I
After editing the SQL files, I ran them using this command in a DB2 Command Window:
db2 -v -td; -f C:\t
And the same for CreateTS.sql.
Create application server profile
I used the advanced option when creating an application server profile using the Profile Management Tool. I chose not to install the default application, gave the profile a meaningful name and picked the Development tuning setting. Administrative security must be enabled for MDM, and the advantage of creating the profile yourself is that you get to choose the username and password. If you run the Profile Management Tool as administrator, you will also be given the option to run the server process as a Windows process, which isn't necessary for a development environment.
Important: When creating a profile for use with the MDM Workbench, make sure you create it in the default location with a directory name that matches the profile name.

InfoSphere Master Data Management operational server v11.x OSGi best practices and troubleshooting guide
Note: This preview only covers the initial set up of the MDM Workbench. The
The goal of this article is to show best practices and optimal development practices for developing with the InfoSphere MDM operational server. We will discuss common OSGi patterns, troubleshooting, including failures and resolution, as well as how to best deploy MDM composite bundle (CBA) extensions.
The InfoSphere MDM version v11 operational server is based on an enterprise OSGi architecture, which is modular in nature. The benefits of a modular architecture application design include reducing complexity, reducing time to delivery, and increasing serviceability. The Java EE infrastructure leveraged in previous versions of InfoSphere MDM had limited ability to enforce or encourage a modular design.
The advantage of a modular MDM application is to allow customization to be deployed without having to alter the core MDM application. Instead, customizations are attached in the form of extensions to the core MDM application. This is done using composite bundles, or CBA files.
Optimal workspace operational server configurations
The InfoSphere MDM Workbench is a tool that supports development of customizations and extensions to MDM operational server. The MDM Workbench allows you to define the desired data model and transactions and then generates the code required to implement the MDM Server extensions.
When using workbench to build and deploy your MDM customizations and extensions, there are a few workspace configurations to consider for achieving the best performance and development experience.
As of version 10.1, MDM is secured by default. This means that using the Web Service Explorer to test your web service will not be possible. Whilst there are many web service testing tools out there like SOAPUI, there is one that is included within the MDM Workbench that you can use, the Generic Service Client. The following steps detail how to invoke the required MDM web service :

Developing behavior extensions for InfoSphere MDM v11
Special thanks to Stephanie Hazlewood for providing guidance as well as content for some of the sections of this article!
Many established organizations end up having unmanaged master data. It may be the result of mergers and acquisitions or due to the independent maintenance of information repositories siloed by line of business (LOB) information. In either situation, the result is the same – useful information that could be shared and consistently maintained is not. Unmanaged master data leads to data inconsistency and inaccuracy.
One of the most fundamental extension mechanisms of InfoSphere MDM allows for the modification of service behavior. These extensions are commonly referred to as behavior extensions and the incredible flexibility they provide allows for an organization to implement their own “secret sauce” to the over 700 business services provided out of the box with InfoSphere MDM. The purpose of this tutorial is to introduce you to behavior extensions and guide you through the implementation, testing, packaging and deployment of these extensions. You will be introduced to the Open Service Gateway initiative (OSGi)-based extension approach introduced in the InfoSphere MDM Workbench as of version 11.
With the release of InfoSphere MDM v11, we adopt the OSGi specification which allows, amongst many other things, extensions to be deployed in a more flexible and modular way. This document will describe a real client behavior extension scenario and step you through all of the following, required steps:
- Extension scenario outline.
- Creation of the extension project.
- Development of the extension code.
- Deployment of the extension onto the MDM server.
- Testing deployed code using remote debugging.
We will then conclude this document with the summary of what you have learned.
It is often necessary to customize an MDM implementation in order to meet your solution requirements. One of the extension capabilities InfoSphere MDM provides it the ability to implement additional business rules or logic to a particular out-of-the-box service. These types of extensions are referred to as behavior extensions, as they ultimately change the behavior of a service. In this tutorial we will create a behavior extension to the searchPerson transaction.
The searchPerson transaction is used to retrieve information about a person when provided with a set of search criteria. You can filter out the result set by active, inactive or all records that get retrieved by these criteria. Important to note is that this particular search transaction uses exact match and wildcard characters to retrieve the result set. There are separate APIs available for probabilistic searching – this service is not one of them.
Sometimes, the searchPerson transaction response may contain duplicate parties. For example, if a party contains both legal and business names which are identical, and searchPerson transaction uses last name as criteria, - the parent object will be returned twice in the response, as it will be matched by both of the names. While this behavior is acceptable in some circumstances, some cases might more filtering before it is returned. In order to do so, we will create a behavior extension, which will be responsible for processing transaction output and removing any duplicate records in the result set. The InfoSphere MDM Workbench provides us with exactly the right tools to quickly create and deploy such an extension.
Creating extension project
First, create the extension project structure using the wizards provided by MDM Workbench. Go to File -> New -> Other… and search for Development Project wizard:
If you cannot find Development Project wizard within the list, chances are the Workbench has not been installed, please verify using IBM Installation Manager.
When creating your project, make sure to specify a unique project and package names in order to avoid conflict with the existing ones:
Make sure to choose the correct server runtime for your projects, as well as unique name for the CBA project:
Note: You are allowed to choose from the existing CBAs. A single CBA can contain multiple development project bundles.
Click Finish and wait for the wizard to generate the required assets.
At this point, what we have is a skeletal InfoSphere MDM Development project that contains all of the basic facilities to help us create the desired extension. The next step is to create the extension assets and there are two ways of doing so: either by using the behavior extension wizard, or by using the model editor.
Creating a behavior extension using the extension wizard
You can create an extension using a wizard in the MDM Workbench, much like the one used to create a development project:
1. Open Behavior Extension wizard by going to File -> New -> Other… -> Behavior Extension, located under Master Data Management -> Extension folders
Note: A development projects can contain multiple extensions of various types underneath it. You might choose to use development projects to logically group extensions having a similar purpose, type or to facilitate parallel development activities.
3. Within the next window, choose a name and a description for your behavior extension. Choose a Java class name for your extension. This is the class that we will be populating with custom logic in order to achieve desired behavior. Alternatively, if you require to use an IBM Operational Decision Manager (ODM, and previously known as ILOG) rule – specify this associated parameter. ILOG/ODM rule creation is not covered as a part of this tutorial as we will implement the extension in as a Java extension.
4. Within the “Specify details of the trigger” pane, you need to specify the following parameters:
a. Trigger type:
i. ‘Action‘ will cause the behavior extension to trigger whenever chosen transaction is ran by itself or as a part of another transaction. ‘Actions’ are executed at the component level. .
ii. On the other hand, if you are looking to trigger extension only on a specific standalone transaction event (otherwise known as controller level transaction) select ‘Transaction’ trigger type.
iii. ‘Action Category’ trigger type executes behavior extension on various data actions such as add, update, view or all for extensions to be executed at the component level.
iv. ‘Transaction Category’ trigger type will kick off behavior extension when a transaction of specified type is executed, namely inquiry, persistence or all.
b. When to trigger:
i. ‘Trigger before’ will cause the behavior extension to fire of before the work of the transaction is carried out. Sometimes you will hear this referred to as a preExecute extension. It is a typically used when some sort of preparation procedure has to be executed before the rest of the transaction is carried out. An example of such scenario would be preparing data within the business object that is being persisted.
ii. ‘Trigger after’ will cause the behavior extension to run after the transaction work has carried out. Sometimes you will hear this referred to as a postExecute extension. It is typically used in the scenarios where logic implemented in the behavior extension depends on the result of the transaction. Normally any sort of asynchronous notification would be placed in a post behavior extension, as there would be no way to roll it back in case of transaction failure, if it is sent before the transaction is executed.
c. ‘Priority’ parameter indicates the order in which this behavior extension will be triggered. The lower the priority number, the higher the priority. That is, a behavior extension with priority 1 would execute first followed by behavior extension with priority 2, 3 or 4 in that order.
In our scenario we are looking to filter the response of a specific transaction,, namely searchPerson. Therefore we set the trigger type to be ‘Transaction’ with value of searchPerson. Since we are filtering the response of the transaction – we have to trigger our behavior extension after the transaction has gone through, and response became available. Lastly, in our particular example priority does not play a special role, so we will leave it at default of ‘1’.
5. After the above configuration is done, click Next and review the chosen parameters. Note that there is a checkbox at the top of the dialog, allowing you to generate the code based on the specified parameters immediately. For the purposes of this tutorial leave it checked and click Finish. The workbench will generate all of the required assets for you.
Creating a behavior extension using the model editor
If you have used the wizard approach above to create the behavior extension already, please feel free to skip ahead to the section titled, “review generated assets” that follows.
This section describes how to generate a behavior extension using the model editor. To do so, the following steps will guide you through this process:
1. Go to the development project you created earlier and open the module.mdmxmi file under the root folder of the project. Select the model tab within the opened view.
2. Right click Part
4. Now we will create a transaction event definition under behavior extension. Right-click the behavior extension, then select New - > Transaction Event.
5. Once the transaction even has been created, specify the appropriate properties:
a. Because this event is triggered on the personSearch transaction, PersonSearchEvent is appropriate. Recall that sometimes the “trigger before” behavior is referred to as “preExecute” extension.
b. Because ‘Pre’ checkbox stands for preExecute, (more specifically the behavior extension gets executed before the rest of the transaction) leave it unchecked. Similar to the wizard configuration, leave priority as ‘1’, since priority of execution does not affect this behavior extension.
c. Finally, select searchPerson as the transaction of choice by clicking Edit… -> Party -> CoreParty -> searchPerson.
After all of the above configurations are done and reviewed, go ahead and click Generate Code under the Model Actions section of the view, telling workbench to generate configured assets.
Review your generated extension code
Once either of the above methods is used, let us review the generated assets:
o EXTENSIONSET table record defines the behavior extension, its associated class best
o CDCONDITIONVALTP defines a new condition of transaction name being equal to searchPerson.
o EXTSETCONDVAL connects the above CDCONDITIONVALTP record to the behavior extension record from EXTENSIONSET. Additionally another EXTSETCONDVAL record connects CDCONDITIONVALTP with id of ‘9’, which stands for execution of behavior transaction after transaction.
Let us now move on to developing the extension code required to filter out duplicate person records from the result set returned by the searchPerson transaction.
Develop the extension code
The behavior extension skeleton and supporting configuration assets have now been generated. You add your custom logic, or behavior change, in the execute method of Pers
public void exec
// Only work with vectors in the response
// Get the response object hierarchy
// Iterate through the party search result
// objects to find duplicates
Iterator listIterator =
// We will keep the party ids of objects we've already
// processed to identify the duplicates
Vector partyIdList = new Vector();
Object o = list
if(o instanceof TCRM
String partyId = pers
// If the party id has not been seen yet, this person
// object is not a duplicate, otherwise - remove it from
// the response
Note: The above implementation is not pagination friendly and pagination will not be covered as a part of this tutorial.
Once you have compiled the code above, you will notice that some of the classes are not found and have to be imported. You cannot simply import TCRM
After recompiling the projects again, you will notice that the Part
This error is occurring because the composite bundle that contains Part
Now that all compilation problems have been resolved, we are ready to deploy our extension onto the server.
Deploying your new behavior extension to MDM
Once the implementation of the behavior extension has been developed, we are ready to deploy it onto the server. There are two steps involved into the deployment:
- Deploying code to the server.
- Executing generated SQLs to insert required metadata.
Deploying code to the server
Our customized behavior extension can be deployed to the server as a Composite Bundle Archive (CBA) as follows:
1. Make sure that the customized code has been built and then export the CBA containing the behavior extension by right clicking the CBA project and selecting ‘Export… -> OSGi Composite Bundle (CBA)’.
2. In the opened view, select Part
3. Click ‘Finish’. The CBA containing the behavior extension has now been exported to selected location.
4. At this point, we will assume that the MDM instance is up and running. Let’s open the WebSphere Administrative Console. We are looking to import our new CBA into the internal bundle repository. To do so go to Environment -> OSGi bundle repositories -> Internal bundle repository. In the opened view, click New…, choose Local file system and specify the location of the CBA we’ve exported above. Save your progress.
5. Once the CBA has been imported, attach this new bundle to the MDM application. Go to Applications -> Applications Types -> Business-level applications. Choose MDM application from the opened view. In the next open view, open the MDM .eba file.
6. We are now looking at the properties of the MDM Enterprise Bundle Archive (EBA). In order to attach our CBA, go to Additional Properties section and select Extensions for this composition unit.
7. If this is the first extension that you’ve deployed on your instance, the list of attached extensions will be empty. Let’s now click Add…, and check the CBA we’ve imported above, then click Add. Wait for the addition to complete. Save your changes.
8. You may think that we are done here, but not quite. We’ve only updated the definition of the EBA deployment by adding our extension. The MDM OSGi application itself has not been updated and even if you restart the server, your new behavior extension will not be picked up. So you must update the MDM application to the latest deployment by returning to the EBA properties view.
Before we attached our extension, the button shown above was grayed out; the comment stated that the application is up to date. But since we’ve update our application with a new extension bundle, we need to update it to the latest deployment. Go ahead and click the Update to latest deployment … button.
9. In the next view, you can see that the Part
At this point, scroll down and click Ok to proceed. It may take several minutes depending on your system hardware.
10. At this point, WebSphere will take you through three views, offering multiple information summaries of the deployments and several customization options. There is no need to customize anything, go ahead and click Next three times, followed by Finish. At this point the application will update. It may take some time; please allow 5 – 10 minutes to complete depending on underlying hardware. Once it is complete – save your changes. At this point, the MDM application has been updated to the latest deployment which includes our extension.
Now we need to deploy our custom metadata to the database. This metadata will govern the behavior of our extension in ways discussed above.
Deploy metadata onto the MDM database
As mentioned earlier in this tutorial, the Workbench generates database scripts that insert the required configuration into the metadata tables of the MDM repository. This metadata is generated based on the parameters we provided for our behavior extension as part of the Creating extension project section. In order to deploy this metadata to the database, run the database scripts listed under the resources -> sql folder that are appropriate for your database type. Conversely, if you need to remove extension from the server, you would need to run the rollback scripts provided in the same folder.
Note: In the case where some portion of the script fails, please investigate the error, because it may render the extension useless. Potential reasons for an error may include residual data from previous extension (rollback was not run when extension was removed), incorrect database schema, etc.
Once the scripts have been successfully run, you’re your behavior extension has now been successfully deployed. Restart your WebSphere server so that your new metadata gets picked up when the application runs next.
Testing deployed code using remote debugging
Now that all of the aspects of the behavior extensions have been deployed, we are ready to test it out! To do that, run a searchPerson transaction. It is required to have at least one person in the database so that you can actually search and yield a successful search result to trigger your new extension. This test will show us that the extension is successfully deployed. Once the transaction returns as successful, go to the SystemOut.log of the WebSphere server which is located under the log folder of the WebSphere profile where MDM application is deployed. If the extension has deployed correctly, due to the following line in our custom code:
You should be able to see this message in the logs:
[6/17/14 13:24:59:816 EDT] 000001b3 SystemOut O Part
Note: The log message is there for testing purposes only, and depending on the usage of the behavior extension can significantly impede performance. For that reason please make sure to remove such debugging messages or put them into fine logging level before going into production. Such as:
Configuring WebSphere Application Server debug mode
To observe the behavior of our extension more closely, put WebSphere server into the debug mode, and connect MDM Workbench to the said server in order to debug our code step by step. To put your server in debug mode:
1. Go to WebSphere Application Server administrative console, and navigate to Servers -> Server Types -> WebSphere application server -> <Name of your instance>.
2. Once in the server configuration view, take a look at Server Infrastructure section and navigate to Java and Process Management -> Process definition.
3. In the Additional Properties section, select Java Virtual Machine.
4. Once we are in the Java Virtual Machine view, navigate down to the Debug Mode checkbox, check it and provide the following settings in the Debug arguments textbox:
Note that ‘7777’ is the debug port to which the MDM Workbench will connect. Make sure this port does not conflict with any other assigned ports on the server, and set it accordingly.
5. Save configuration and restart your server. It is now running in debug mode. Note: If later you observe unexpected performance degradation and do not require debug mode any longer, make sure to take the server out of the debug mode using the same steps.
Configuring MDM Workbench to for remote debugging
Once the server is running in debug mode, we can go back to the MDM Workbench and configure it for debugging:
1. In MDM Workbench, go to Run -> Debug Configurations.
2. Within the Debug Configurations window, double click Remote Java Application. This will create a new Remote Java Application profile.
3. When configuring the Remote Java Application, lets name our configuration ‘MDM Local Instance Debug’. The Project setting does not play a role, you may leave it empty, or whatever the default populated value is. Connection Type should remain as ‘Standard (Socket Attach)’. Lastly Connection Properties should reflect the location of the MDM instance and debug port we’ve chosen above.
We will not cover other tabs because the configuration we’ve done so far is sufficient.
4. Once configuration is complete, hit Apply followed by Debug in order to attach to the MDM instance. The attach process may take a little bit of time depending on the environment. Once it is complete, go to the Debug perspective of your environment. In the debug view, you should observe the connected MDM instance if the attach was successful:
You can see above that the instance is available along with all of the threads.
5. Finally set a break point at the beginning of the behavior extension execute method and observe this breakpoint getting engaged once we run a searchPerson transaction:
6. If you have multiple TCRM
As a last point, note that we can debug both local and remote instances as described above, using Eclipse’s Remote Java Application debug capabilities.
In this tutorial we’ve gone through the steps of creating, configuring, deploying and testing a basic yet realistic behavior extension scenario for InfoSphere MDM.
We’ve covered two ways in which an extension template can be created: while the wizard option is straightforward and is preferable for a novice or a simple extension scenario, the model editor allows for more flexibility.
We’ve taken a look at the various configurations that apply to a behavior extension and outlined their effects on its execution. Additionally, we’ve covered the assets that get generated as a result of the configuration.
For the development step, we’ve created and analyzed the implementation of our behavior extension.
And finally, we’ve deployed, tested and debugged our behavior extension to make sure it performs as expected.
All of the above steps constitute a complete development process of an MDM Server behavior extension.

MDM v11.3 leverages IBM BPM technology to provide a data stewardship framework under a single UI. However, it may be desirable to modify this UI to match the look and feel of your existing solutions. While BPM Process Designer allows you to restructure page layout with the Coach designer, the best way to modify the look and feel of a Coach is with CSS.
BPM provides three ways to alter CSS out of the box from within Process Designer:
However, there are occasions where these approaches are not suitable:
The ideal way to insert CSS into a Coach would be to load the CSS as a managed file in BPM - that way you only need to edit the managed file and all Coaches that reference the CSS would use the latest version (pending updated snapshots). Unfortunately, BPM does not offer the mechanism out of the box.
Update 05/11 - If you upload a HTML file to BPM that consists of <style> tags wrapping the CSS, you can use the "Managed File" option of the Custom HTML component to load the "HTML" CSS into the Coach. However, this does not work if the HTML file is inside a .zip archive, or if the CSS needs to reference local resources.
By using this method call, you can get a relative URL to the managed file in BPM - eg
Using the above technique, I created a HTML file containing a <script> that would create a link to the URL for a CSS file in the document's <head> element. I then used the "Managed File" option on a Custom HTML component to load the script into a Coach. This meant that my CSS file was referenced inside the <head> element.
You can use this principle to load your own custom CSS files into a Coach. Custom CSS files can be used to override BPM Coach Views or Coaches, or alternatively CSS files can be used to override the MDM Coach Views supplied with MDM V11 onwards.
As an example, I present an updated solution to:
