The mapping and normalization feature is used when mapping multiple public user identities to one private identity.
With the vast array of communication devices and contexts for which we use these devices, it is not uncommon to have more than one user identity for the various devices. Although a person can have multiple public user identities, the person behind the public user identities is still the same and there are situations where it is useful to map the public identities to one primary private identity.
There are many scenarios where the mapping should take place, for example access control. If you are granted access to a document with one public identity, you should be allowed to access that document with another public identity. For customers wishing to implement multiple public identity mapping, the IBM® WebSphere® XML Document Management Server Component (XDMS) provides the following:
Implementation of multiple public identity mapping will be customer dependant. Samples and more information on developing implementations are provided in the Telecom Application Enablement Feature and Telecom Application Enablement Feature Information Center.
Unique identifiers (UID) are normalized for consistency within the IBM XDMS. The way IBM XDMS performs normalization is defined by a set of properties.
When a UID is used to specify a document or directory, IBM XDMS normalizes the UID. This includes UIDs embedded in document selectors, as well as, whenever a UID is used to specify a user directory or match a service URI.
