So I looked at Stephan Decker's page: http://www-db.Stanford.EDU/~stefan/updates.html about "Proposed Updates of RDF", a definitely interesting page which should be updated and completed regularly. The first section: "Tracing RDF statements" provides a summary of the mailings and links to this subjet. It was proposed that the model origin could be stored with the triples The model origin (model) could be stored >with the triples, but for the application appear as a bag of triples >in a read-only state. And you can then say whatever you like about the >whole bag, or any of the triples inside. Agreed. But then it is a requirement for the software implementing the Query API to do this (gets complicated - forget about simple mappings to databases....) Not necessarily, only the triples will become a "quatuor", i.e. each triple will be completed with its "model origin"=locutor . It is interesting to note that this "model origin" will generally be a URL or in-memory object, because if you have a triple in your database, you have obtained it from some real place, not from an URI. It will only be a URI if the application has a built-in collection of triples as a configuration or default. For an in-memory object, it is the case of data just entered by the user, whose name and hostname are generally known, and can make a URI. -- <person> <firstName>Jean-Marc</firstName> <lastName>Vanel</LastName> <project>Worlwide Botanical Knowledge Base - making botany available on Internet <a href="http://wwbota.free.fr/" >site</a> </project> <a href="http://jmvanel.free.fr/>home page</a> <a href="mailto:jmvanel@free.fr">mail (possibly put "wwbota" in subject to route your mail in relevant folder)</a> </person>
