DOM for RDF?

2013-12-02 Thread Richard Light
Hi, I'm sure this has been discussed many times and/or ages ago, but I am struck by the absence of a DOM-like W3C framework for RDF. By this, I mean an application programming interface (API) for [RDF graphs], which will be a standard programming interface that can be used in a wide variety

Hi Richard from my point of view the DOM-like approach does exists yet, and it's by SPARQL and LDpath. What are them lacking? Do you feel there should be an object-oriented approach? As for the Jena model or Sesame internal Graph representation? If this is the case it could be interesting from my

Thanks Andy, Sorry, I had a brain-fart (senior moment?), and forgot that we were dealing with RDF 1.1. I guess I have suffered the pain of unknown presence of datatypes in the RDF terms for literals for so long it takes a while for me to accept that it has been fixed. Thanks so much to the

I think my conclusion from the DOM experience was that actually people wanted jQuery -- something optimized for the language. My own RDF APIs have been optimized for js and python respectively, though they share style and many calls. See undocumented rdflib.js

Hmm, My head is spinning a bit now - I’m trying to understand something simple - 1^^xsd:boolean. So my reading says that is a valid lexical form (in the lexical space) for the value ’true’ (in the value space). (http://www.w3.org/TR/rdf11-concepts/#dfn-lexical-space ) I think that ‘value space’

Richard, I think Graphity is close to what you're looking for: https://github.com/Graphity/graphity-browser It supports SPARQL Protocol and Graph Store Protocol, content negotiation, XSLT transformations of RDF output and RDF input user interface using RDF/POST

Yes Richard, i agree and mybe my reply ws not so clear regarding what i mean. I like the ld-api (such as Elda) which uses ldpath much like xpath is used in the XSLT or DOM context... the next step in that direction could be marmotta, i agree on that. I also love very much Sail or the gremlin
