IBM InfoSphere MDM Custom Domain Hub, Version 10.1

Introduction to InfoSphere MDM Custom Domain Hub module projects for modifications

Before creating modifications, an InfoSphere® MDM Custom Domain Hub module project for modifications must be created

An InfoSphere MDM Custom Domain Hub module project contains a set of related modifications to InfoSphere MDM Custom Domain Hub.

The application model file (application.mdmxmi) contains code generation options that apply to all the modules that are part of the same application. In particular, you can change the Hub Base Name and set the database schema name used when generating SQL files in the application.mdmxmi file.

The module model file (module.mdmxmi) file contains definitions of the customizations that you are developing and is the input for code generation. Definitions of the various data additions, extensions, transactions and so on are created in this model. Additional definitions can be added to this model using the Hub module model editor. When you are you happy with the model contents, you can use the Generate implementation action from within the editor to generate the implementation.

You can modify the module model file using the Hub model editor. This editor provides two tabs that separate general project properties (the Overview tab) from the hub model itself (the Model tab). The Overview tab shows the properties supplied when the project was created. In the Overview tab's Metadata section, the following two properties define a numerical range used during code generation to allocate certain unique key values:

Start ID: The starting value used for allocating unique IDs.
Maximum offset: The maximum offset from the Start ID that can be allocated.

This range is automatically configured when the project is created to ensure that it does not conflict with other projects in the workspace. When projects are imported, you may need to manually adjust the Start ID and Maximum Offset values to ensure a unique range for each project.

The project also contains two other files:

mdmgen.xml: This ANT script is run to generate code from the module model.
mdmgen.properties: This file allows you to set properties that affect the code generation process.
