Dear Virtuoso developers, In your new 6.1.8 release you claim support for SPARQL VALID(). A search in the SPARQL standard docs does not seem to reveal such a function. Is this like your extension ASSUME()?
I understand the need for extending the standard, as well as postels law. However, please think of ways adding such features that do not add new keywords to the SPARQL language. You could for example add this functionality in comments instead. PREFIX bioh: <http://virtuoso/optimizerhints> PREFIX dc: <http://purl.org/dc/elements/1.1/> SELECT ?book ?title WHERE { ?book dc:title ?title . #bioh:assume(?title, isIRI) } This is nicer for those of us who need to support multiple stores and still want to support Virtuoso in a way that is as good as possible. Again, I understand the reasoning for adding new features. Yet I urge all of you think again about the exact way you have added and advertised these features.
