After chatting with Guus, here are the options we'd like to propose for
the multi-graphs example in the primer.

1) After the TriG listing, adding something like "RDF 1.1 doesn't
prescribe any specific semantics for datasets. Possible semantics are
described in [DATASET-SEMANTICS]. In this example dataset we assume
graph names represent the source of the RDF data held within the
corresponding graphs, i.e. by retrieving <http://example.org/bob> we
would get access to the four triples in that graph. In the default graph
we associate provenance information with the <http://example.org/bob>
2) Adding a statement to the example:
    <http://example.org/bob> a eg:WebSource . (or sd:NamedGraph? or
something else?)
and explaining that eg:WebSource (or else) identify graph names that can
be accessed through HTTP to retrieve the corresponding graph content.
3) Adding a statement to the example similar as in section 4 of
[DATASET-SEMANTICS], on the dataset itself, to express its semantics,
    <> a sd:Dataset ; eg:semantics <rdf-dataset#3.3>

To me, it seems like option 1 is probably the simplest to implement (no
need to change the example, just adding a bit of text). Option 2 and 3
are OK as well, but we'd need help with them - e.g. what vocabulary
should we use?

Also, if option 2 doesn't work, we (and Markus apparently, from his
earlier email) would like to understand why.
