Hi Andy, I agree with you. A consistent style of would be better. In the project proposal, I just listed the features that we could do. As to the property function names, the arguments and the styles, they can be discussed and adjusted. Best regards, Ying Jiang On Thu, May 2, 2013 at 7:30 PM, An

Hi Andy, The link about the spatial relationships you provided is very interesting. I've tried to study Lucene to figure out whether they are possible to be implemented. Shall we use Lucene 4.x or 3.x? For the current release of Lucene 4.2.1, it provides a high level abstraction for spatial query

This is a potential GSoC project - I'd see it firstly being a separate codebase as it develops, then get some people using it and providing feedback and, if it's popular, it can move into Jena proper. The nice thing is that doesn't (err "shouldn't") require modifications to the main modules as

This is an awesome idea which could be extensively used if implemented (I would!). Is this going to be a stand-alone project for GSoC? I would be interested in working in this. Thanks ~Gyan On Mon, Apr 15, 2013 at 9:37 AM, Andy Seaborne wrote: > === Spatial query > JENA-10 > > Not all spatial
