Hi all, I have a question regarding your comments about sections 4.1 Definition of Service and 4.3 Service evaluation semantics (now sections 3.1 and 3.2). In section 3.1 the evaluation of SERVICE is defined using an algorithm meanwhile in section 3.2 I use an algebraic expression. Section 3.1 received several comments from you both (Axel and Lee) and section 3.2 none. Both sections describe the same, the service semantics. I'd prefer to remove section 3.1 and leave only section 3.2 for describing SERVICE semantics. For me it contains a clearer and cleaner definition. The only thing missing is the silent op function, but I would add it in the next days. I need to think a little bit about it. Also, a bit more textual explanation would be needed. any comment? > > * 4.1 I don't think this should restate the text from SPARQL 1.1 > Query.
