If linear search using the existing attribute indexes is all that is available now, that is fine. It would be fantastic to write a geo spatial index to support that API in basex in the future. What type of indexes have you considered? I would think an Rtree would probably be best for supporting that API. > > This email is essentially a status query – as I work on this over the next week or two we can start new threads for specific topics. > > > David Stuebe > > Scientist & Software Engineer – RPS ASA > > 55 Village Square Drive > South Kingstown, RI 02879-8248 > > Tel: +1 (401) 789-6224 > > Email: David.Stuebe at rpsgroup.com > www: asascience.com | rpsgroup.com > > A member of the RPS Group plc > > > _______________________________________________ > BaseX-Talk mailing list > BaseX-Talk at mailman.uni-konstanz.de > https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk >
