I agree with you on this, and I think it is important enough
that we should say it clearly like this -- somewhere... maybe
in an entry on "Records".  But it should perhaps also be
acknowledged that the Linked Data space does not have a
universally agreed way to express a bounded record.  This is
a gap that DCAM, for example, tried to address.  The RDF
community has spoken of "named graphs" for a number of years,
but the term is still ambiguous (does it refer to quoted
graphs? graph literals? URIs for graphs?  graph stores?).
Standards-based support for provenance in Linked Data will
depend on what is now referred to as "support for multiple
graphs and graph stores".  For the glossary, we should avoid
going into this sort of detail but this is such an important
difference in paradigm that we should try to characterize
the issues in a few sentences somewhere.
