Looking for JSON, ReST, (and in-memory RDF) frameworks
Currently writing a number of small web-services to do various informatics tasks (more detailed post to come). Fortunately I'm not the one having to deal with 3rd-party SOAP apis! Still I do need to do various XML and JSON parsing, and not having addressed the latter before I've gone looking for libraries.
Currently I am about to start using Jackson, but was wondering if anyone had any warnings, advice, or recommended alternatives? In the course of looking at what was out there I have also come across Restlet, a ReST framework that seems like it is well worth the time to figure out and deploy, so I will probably be doing that soon as well, any warnings or advice on this will be welcome.
One of the nice things about Restlet is its support for RDF. Granted it doesn't support querying, and the terminology in the interface is a bit confused, but it does use its native Resource interface for URIRefs, so it should integrate well. OTOH, if it does prove useful as a ReST framework, I can see myself writing a quick Sesame or Mulgara extension, as there is only so much you can do with RDF before you need a query and/or data-binding interface.
