Simon, with LDT, every application is a service, backed by SPARQL dataset, and driven by an ontology. The service description is made discoverable by making the ontology dereferencable. Every LDT response contains header information linking the resource back to the application, to its ontology,

It's pretty common to see "RDF-to-X" or "X-to-Y" bridges that address the problem of converting one data structure to another, for instance, you have a Java object and serialize it to RDF or you have RDF data and you populate a Java class with it. If you consider just "Java" of course you can

Just for information, you might want to look at SSWAP: http://sswap.info/ http://bmcbioinformatics.biomedcentral.com/articles/10.1186/1471-2105-10-309 They used OWL to assemble web services, and you might find useful ideas there. Using SPARQL this way seems like an awful lot of overhead. Is

Hello, Right now I'm designing a distributed software system whose components (or services) communicate through protocols. In order to minimize the efforts to create and handle protocols I had the idea to only use linked data for communication. I would like to use SPARQL to send requests to
