Re: Fuseki v.17 seems not to work
Hi Andy, The instructions I always give to my students are go to http://jena.apache.org/download/index.cgi Download the latest version of apache-jena-fuseki-3.17.0.zip (now this is the latest) unzip and so on. [cid:15d1f741-dc49-4b7e-bb96-2b25d0178845] Add new dataset would not open, neither upload files. [cid:63cdb8b1-6980-4a64-8a57-d22d9d4f30e3] Thank you so much. Regards, Neli.

Re: Fuseki v.17 seems not to work
Neli, There are several packaging of Fuseki - which one are you referring to? What does "not work" mean for you and your students? > It open on the local host, do you get the front page?

Re: Fuseki v.17 seems not to work
I am using 3.17 and it works just fine.

Re: Fuseki v.17 seems not to work
I mentioned a similar issue the other day. Could not get browser to talk to the server. I downloaded 3.16 and it worked fine. I am currently running 3.12 without issue.

Hi there, I am using Fuseki for my Linked data engineering class. My students were ask to download the latest version 17 (from the website) and it seems to not work.

Thanks. I get a "That didn't work for some reason" error from dropbox.

Re: Suggestions for learning more about SPARQL query performance?
Thanks. I'm looking to get smarter in general about formulating queries, particularly those with non-trivial graph structure, e.g., more than just a shallow tree of properties rooted in one resource, maybe dags, maybe with cycles. I am open to post-processing query results. (I do that already, generating and post-processing queries are steps in the overall algorithm.)
