Customization restrictions

One of the prime objectives of InfoSphere® MDM architecture is to support customization and extension of the core product.

This is achieved by providing extension hooks for extending services, business rules as well as data. Most of the infrastructure components allow for pluggable implementations, allowing clients to customize the behavior by writing and configuring their own plug-ins.
All extensions, customizations and configurations to InfoSphere MDM are handled without impacting existing product assets. In order to preserve the ability to upgrade from release to release, do not alter the following assets from your InfoSphere MDM product:
  • Core XML schemas (XSDs)
    Tip: Client extensions may be added to the XSDs.
  • Properties files
  • Business objects
  • Controller and business components
  • Java™ implemented external rules
Important: Where required, skeleton extension files are provided for extension XSD and extension XML schema files, as well as for the extension properties file.
