OMA XML Document Management V2.0
The XDM V2.0 enabler defines new functionality that extends XDM to support the OMA SIMPLE Instant Messaging (IM) V1.0 and Push-to-talk over Cellular (PoC) V2.0 enablers.
To accommodate the needs of these enablers, the following functionality is added in XDM V2.0:
- Search for information in documents stored in an XDMS;
- Network to Network Interface to enable search and retrieval of information across multiple domains.
XDM V2.0 inherits the Shared XDMS from XDM V1.0, but renames it as the Shared List XDMS [XDM_List] to accommodate several new documents that are stored in separate Shared XDMS logical entities:
- Group document stored in the Shared Group XDMS [XDM_Group];
- User Access Policy document stored in the Shared Policy XDMS [XDM_Policy]; and
- User Profile document stored in the Shared Profile XDMS [XDM_Profile].
The Group and User Access Policy document structures are based on those of the PoC Group and PoC User Access Policy documents [PoC_XDM], respectively. The XDM 2.0 enabler defines how to handle backwards compatibility with the PoC V1.0 enabler when the Shared Group XDMS and Shared Policy XDMS are introduced in the network.
