IBM InfoSphere Master Data Management, Version 10.1In WebSphere® Commerce an attribute dictionary is a set of common attributes as well as attribute values. It is a feature used to manage a set of attributes and its values that can be reused by multiple WebSphere Commerce catalog entries. If an attribute is changed in the WebSphere Commerce attribute dictionary, all WebSphere Commerce catalog entries that share that attribute are updated.
Changes to attribute definitions are only allowed if they amplify (but not restrict) the specification. This is necessary so that the already existing items using the attribute remain with valid values. The attribute dictionary allows creating defining attributes and descriptive attributes (which are grouped according to the needs of modeling product-types, for example, a group of descriptive attributes for a product type “smart phone”).
The attribute dictionary is one of the secondary hierarchies for InfoSphere® MDM Collaboration Server catalog catalog entry repository. You can also add the reusable attributes through the secondary spec's associated with the category in the attribute dictionary hierarchy.
Attribute definitions that are not assigned to any entry are still exported to WebSphere Commerce with the rest of the catalog and schema.
