However, we've be doing some modeling here at the VU where the parameter to a program is a string. Currently, this is not modelled using a prov-o:used edge but it seems like it should be. Is there anyway we can support this? I think in PROV-O this can easily be solved by using http://www.w3.org/TR/Content-in-RDF10/ - I explored this briefly in earlier Taverna-PROV-O experiments. :activity a prov:Activity; prov:used [ a prov:Entity, cnt:ContentAsText ; cnt:chars "The magic string" ; ] . Here we did not even bother giving the entity an URI. Of course it would be good practice to give it a URI, even if it's just some fragment within the account: :activity a prov:Activity; prov:used :theMagicString . :magicString a prov:Entity, cnt:ContentAsText ; cnt:chars "The magic string" . (there's also cnt:ContentAsBase64 and cnt:bytes for verbose binaries, and cnt:ContentAsXML for literal XMLs) For PROV-DM we could introduce something like prov:value. -- Stian Soiland-Reyes, myGrid team School of Computer Science The University of Manchester
