How to make complex SPARQL queries reusable?

Hello, I have complex SPARQL queries, which I would like to divide into several parts (like function definitions), in order to reuse these parts among different SPARQL queries and in order to make a single SPARQL query easier to understand. What are my options to achieve this? I had a

Re: full URI of rdfs sub class

You can search for rdfs here: http://prefix.cc/ This leads to a document where rdfs:subClassOf is defined. On Tue, 07 Mar 2017 14:58:20 +0100 kumar rohit wrote > I have a rule like if x is type of Student and student rdfs:subclass of > Human, then x is

Can Jena or linked data in general used as a "service registry"?

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

I need advice about how to implement a "dynamic dispatch" of properties through inference support

Hello there, I'm currently designing a system on top of Jena (or on top of semantic web technologies in general) and I arrived at the point where I need to get inference support for SPARQL queries up and running. I looked at https://jena.apache.org/documentation/inference/ but I'm having
