Mindful of time pressure ...
I suggest the following approach for our paper ...
1) introduce a property
rdfx:assertedBy
whose domain is graphs and range is agents union documents.
2) include examples in which a PKI signature of such a statement is
included in which the asserting agent signs the statement of assertion
3) include text that describes the bootstrapping problem and note that the
example provides one mechanism for bootstrapping trust, but noting that the
HTML web largely works, providing adequately trusted information, without
widespread use of such mechanisms
We might also want an rdfx:notAssertedBy property for explicitly stating
that a graph is fictional, in the eyes of its author (or anyone else).
4) We could include text that suggests that documents published in RDF/XML
should be regarded by default as being asserted by their authors, and point
to the social meaning discussion to show that this was never adequately
resolved.
To me, at least, that provides enough mechanisms for the publishing of
assertional intent, at least for most actual usage.
I think Chris is correct to indicate that the reading agent's trust is a
separate problem that may be increased by the use of signatures but not
increased to 100%.
I think we should address this by postulating a trust layer, which takes as
input a set of named graphs and provides as output a single graph, being
the merge of some of the input graphs, (those which the trust layer chose
to trust). Chris provides some potential trust metrics, and we include the
PKI signature as one of the factors which may be considered.
