> The description of oslc_config:previousBaseline for a stream in https://tools.oasis-open.org/version-control/browse/wsvn/oslc-ccm/trunk/specs/config-mgt/config-resources.html says this:
> "A reference to the immediately preceeding baseline of this stream. Multiple instances of this property imply the stream was merged from one or more baselines, and no baseline of the merged result has yet been taken. If the property is absent, no baseline of this stream has been taken."
> I believe the intent is that this predicate references the most recent baseline created from a stream, and not the configuration that the stream was copied from (which prov:wasDerivedFrom would describe). However, the description hints at both meanings, and I know of at least one implementation that has interpreted it as the latter, and a different implementation as the former.
> If I have understood the intent correctly, I suggest the following changed wording:
> "A reference to the most recent baseline created from this stream.  If the property is absent, no baseline of this stream has been taken. Multiple instances of this property imply the stream was merged from one or more baselines, and no baseline of the merged stream has yet been created."
