Re: Ideas for an efficient TDB check?

Hi Paolo, thanks for your reply and for your great piece of software. It covers almost all ideas Andy mentioned. I'll check if the tuple-by-tuple comparison Andy suggested can be done without performance issues. We use your solution with a few changes* to check our stores periodically. We are cur

Jena Rules: Execution order

According to the documentation "there is no guarantee of the order in which matching rules will fire". So is the general approach to instantiate two RuleReasoners when certain rules require, that other rules have been tested before? For example, let's say there is rule, that adds a statement w

Reverse proxying Fuseki behind Apache

Sorry this maybe a a bit off topic, but just I am just getting started.. I have Fuseki 0.2.2 snapshot running happily but I would give access via another server i.e. users would access http://host2:/fuseki/ which is proxied to http:/host1:3030/ This works (there is a css path problem) but the tpl

Re: Storing jena model to Non SQL Datastore

Yes right now I am just looking to provide a basic graph implementation. So we are okay with the in memory query processing and only wanting to persist and retrieve triples stored via jena. So the link helps a lot. Thanks, P. On Tue, May 29, 2012 at 3:00 PM, Andy Seaborne wrote: > On 25/05/12

Re: how to use Lucene Highlighter with LARQ query

Hi Haroon, LARQ itself does not gives you back the necessary information to highlight keywords you have searched for in the literals you get back as results. However, even if not terribly efficient, if you present your users with a limited number of results you could use Lucene and re-run your qu

Re: Storing jena model to Non SQL Datastore

Hi Rob, just replied to Erik. And discuss off-list. (two reasons for that: the code is not open source yet and it's heavily geared towards GAE) wish we had published that Jena/GAE paper back in 2010 to make the content accessible. I certainly would be interested to feed the improved version back

Re: Storing jena model to Non SQL Datastore

Marco Is it possible that relevant discussion could remain on the list or that you could make a report to the list (or point us to one) that describe the approach taken to build a NoSQL backend for Jena. As Erik is trying to get at something targeting Accumulo would be particularly interesting be
