Hi Basex-ers
I am new to the list but have been working with basex for a few weeks now. We are using basex to search ISO 19115 geospatial metadata. The full text search is simple and works better than any of the existing purpose built catalog tools we have worked with so far.
I am very interested in the pervious thread on Spatial Xquery. https://mailman.uni-konstanz.de/pipermail/basex-talk/2012-January/002484.htm... I am looking over the Geo Module geospatial APIhttp://expath.org/spec/geo today, and also at Zorba's Geo Modulehttp://www.zorba-xquery.com/html/modules/expath/geo implementation. Has the Basex community made an further progress?
The API is the first issue and so far the Geo Module definition looks great. 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.

Dear David,
thanks for your request. Yes, one of our members (Masoumeh) is in fact working on an implementation of the Geo Module (for GML2), and it may get finished in Januar or February. It will closely resemble Zorba’s implementation, and we think about proposing some updates to the official EXPath spec, which is rather spartan when it comes to typing issues, error handling, etc.
As you indicated, linear search will then be supported out of the box. Indexing the data would be the next exciting step, but we haven’t made any concrete plans on when this will happen yet. Maybe anyone else out there?…
Hope this helps for the moment, Christian ___________________________

Hi all,
Also about the Geo module and supporting formats, some libraries, like the newer versions of GeoTools (version 8.0 or newer), supports other formats of Geo Spatial data, that would be way a to expand this module in the future. Right now I am checking it to see how it works :)
Regards Masoumeh
