Re: [CODE4LIB] Fuseki and other SPARQL servers
I have a follow-up: By default, Jetty starts Fuseki with -Xmx1200M for heap. Have you altered this for production? How many triples do you have and how often does your endpoint process queries? Our dataset won't be large at first (low millions of triples), but we can reasonably expect 10,000+ SPARQL queries per day. That's not a lot by dbpedia standards, but I have no idea how that compares to average LAM systems.

Re: [CODE4LIB] Fuseki and other SPARQL servers
I've been using Fuseki for a while myself and have been using it in production. It can be a bit tricky to configure when you want to connect to a jena SDB but it, along with a small jar file from one of the jena developers that manages the SDB database connection, it works pretty well. If you want to have more fun with Fuseki, check out the linked data API implementations called Elda (a java impl) or Puelia (PHP) and connect it to your Fuseki endpoint. -Original Message- From: Code for Libraries [mailto:CODE4LIB@LISTSERV.ND.EDU] On Behalf Of Ethan Gruber Sent: Wednesday, February 20, 2013 2:32 PM To: CODE4LIB@LISTSERV.ND.EDU Subject: [CODE4LIB] Fuseki and other SPARQL servers Hi all, I have been playing around with Fuseki ( http://jena.apache.org/documentation/serving_data/index.html) for a few months to get my feet wet with accessing and querying RDF.
