Re: Converting BNode to Resource

It looks like a reasonable solution to me if you have to work with parsed RDF. It might be higher performance to treat it as a text processing problem... if your data is available in ntriples or nquads you can use regular expressions to accomplish the task. Charles Charles Greer Lead

Binding graph names for WITH and USING

WITH or USING. I am curious about how to write a workaround, short of putting a literal in for ?g Thanks, Charles Charles Greer Lead Engineer MarkLogic Corporation cgr...@marklogic.com @grechaw www.marklogic.com

, and it scales to far vaster realms than any multi-backend system will. If it's your company looking for a solution, you might want to take a look, and I'm always lurking here if you have questions.

RE: Graph.isIsomorphic()

Hi Grahame, Try Model.difference(Model m) You can try it in both 'directions' to see the triples which are in one model and not the other. Hope that's useful, Charles Greer From: graha...@gmail.com [graha...@gmail.com] on behalf of Grahame Grieve

marklogic-jena 1.0.2 and 3.0.2 released

Hi Jena enthusiasts, I'd like to let you all know that new versions of marklogic-jena are available. The 1.0.2 and 3.0.2 releases are much improved with regard to graph modification (adding and removing triples from graphs). Thanks to Andy for helping me understand the internals of GraphView.

RE: Deleting an entire RDF graph

Hi Juan, Seems that if you can do this efficiently "Another thought is to put the RDF graph in a NG and then just clear the NG." then that will be more efficient than following property paths. Interesting question to be sure. Charles From: Juan

RE: jena technical doc

Hello, I did this recently, and it turned out to be pretty straightforward. Andy did a great job with extensibility. I have not announced this project to the list yet because it's not released yet, and it relies on unreleased code in MarkLogic, but this class shows how to implement the SPARQL

Dataset vs. DatasetGraph

backend, it seems to me that I will have to provide a custom Dataset implementation, not only a DatasetGraph. Is this correct? Thanks, Charles Charles Greer Lead Engineer MarkLogic Corporation cgr...@marklogic.com Cell: +1 707 318 0442 @grechaw www.marklogic.com

RE: Implementing a QueryEngine

Thanks Claude and Andy, this is just what I needed. I'm sure I'll follow up with more questions as I proceed. Charles Charles Greer Lead Engineer MarkLogic Corporation cgr...@marklogic.com Cell: +1 707 318 0442 @grechaw www.marklogic.com From: Andy

Implementing a QueryEngine

really only want to make these if the Dataset in question is one of my own. Many thanks, Charles Charles Greer Lead Engineer MarkLogic Corporation cgr...@marklogic.com Cell: +1 707 318 0442 @grechaw www.marklogic.com

Fuseki and multigraphs?

to populate an entire set of named graphs - can I do that with Fuseki over HTTP, or should I stick to tdbloader? Thanks, Charles Charles Greer Lead Engineer MarkLogic Corporation cgr...@marklogic.com Cell: +1 707 318 0442 @grechaw www.marklogic.com
