Re: ANN: EasyRdf for PHP version 0.7.0

Hi Nicholas, Nice work. With regards to your parsers, is it possible to stream parse large documents? (eg, by passing a callback function to the parser that will be called with a batch of triples, as they are parsed) How do the parsers compare with ARC2's parsers? Cheers Keith On Fri, Oct 12,

Re: Expensive links in Linked Data

You can have multiple documents about the same thing. Each document can contain a different (part of the whole) description, and can link to the other related documents. GET /someresource <> foaf:primaryTopic <#thing> . <#thing> foaf:isPrimaryTopicOf , <> . You can then provide more metadata ab

Hi, Is an ontology a software project, a creative work, or data ? Is the intention to license the use of the terms, the triples of the ontology, or the reproduction of the documentation? There is also the dcterms:license property to point to a license. Maybe it is most useful if most ontologies ha

Hi Kingsley, How does this work under the hood? uriburner recognises the last.fm domain, and parses the URI to understand how to call the last.fm web service api? Then it passes the result to the stylesheet ? Normally uriburner would parse the microformats erdf and rdfa in the page right ?
