Section 2.1.11.8 and 2.1.11.9 in the CMIS draft http://www.oasis-open.org/apps/org/workgroup/cmis/download.php/43639/cmis11-draft.pdf define the version-independent membership in Folders and Relationships in terms of Navigation service requests getChildren, getDescendants, and getObjectRelationships. The concept of a version-independent copy can be defined more explicitly by designating an object identifier to represent a version-independent copy in a version series. It facilitates an externalized URI for a version-independent representative copy to enable bookmarking or tagging. It also generalizes the concept of version-independent copy for un-filed versionable documents.
ICOM CSD 2.0 http://www.oasis-open.org/committees/download.php/44405/icom-ics-v1.0-csprd02.zip, which adopts some of the CMIS domain model, introduces the concept of "representative copy" as an optional feature. ICOM CSD stipulates that a representative copy must have its own object identifier that is different from the object identifier of any versioned copy or private working copy of a versionable document.
Assignment of an object identifier to a representative copy of a versionable document is implementation-dependent. A representative copy may retain the object identifier of a non-version-controlled copy (a private working copy at the start of the version series). Alternatively, a representative copy may be assigned a new object identifier that is different from the object identifier of a non-version-controlled copy of a versionable artifact. The object identifier of a representative copy should not change once it is assigned (a representative copy cannot be deleted).
Content and state of a representative copy of a versionable artifact in a version series is also implementation-dependent. A representative copy may be a copy of the content and state of the latest versioned copy or the latest major versioned copy in a version series.
