GoodRelations vs. Google RDFa vs. Open Graph vs. hProduct/hListing: Using GoodRelations in 10 Triples

2010-05-03 Thread Martin Hepp (UniBW)
Dear all: Some people think that the GoodRelations ontology for e-commerce (http://purl.org/goodrelations/) is powerful, but complex. I think it is important for everybody in the community to know that GoodRelations can be as simple (or simpler) than any more lightweight approach for product

Apologies - There were a few minor bugs in the initial markup: - I forgot the business function. - The datatype for the price was xsd:string instead of xsd:float. - The legal name had no language tag. The correct examples are at

rdf/json

2010-05-03 Thread Nathan
All, Is there an RDF+JSON serialization of RDF, I see mention by Openlink, Talis, RDFQuery etc but not much else. Primarily, is there a spec? a working group? any work being done to standardise? Increasingly more convinced that rdf+json will be mission critical very soon, hence the question.

Perhaps this has already been suggested, but the linked-data-api folks have an overview of json serializations for rdf [1] that might be of some interest. //Ed [1] http://code.google.com/p/linked-data-api/wiki/JSONFormats
