Hi Sergey & Yaron,
I strongly second the idea of supporting FlaggedRevs extension as I'm
using SMW in a collaborative environment to edit data wich is then
exported to third party software. Therefore it is necessary to have
the data available in a specific revised state.
Our very, very basic workaround at the moment: We're saving the
{{REVISIONID}} and {{REVISIONUSER}} (provided by mediawiki) in extra
properties via templates, and allow importing of semantic data into
our third party systems only if the prop:revuserid has one of our
predefined values, so we guarantee that only data wich was last edited
by specific users goes into production systems.
As Sergey said, you would need to store two states of semantic data. I
would go even further and have the semantic data of _all_ revisions of
an article available. Some kind of versioned ontology (see:
http://www.w3.org/TR/owl-ref/#VersionInformation) would become
available. You could then for example query the semantic data of all
reviewed articles (FlaggedRevs) as it was at a specific date/time in
history. The Semantic History extension
(http://www.mediawiki.org/wiki/Extension:SemanticHistory) allows that,
but as I would say in a not so appropriate way and without support for
FlaggedRevs.
