I can’t get the geo:srid() to work. I have tried many combinations of @srsName values. Can anyone provide examples? E. Wray Johnson

Try e.g. this:
  import module namespace geo='http://expath.org/ns/geo';
  declare namespace gml='http://www.opengis.net/gml';
  geo:srid(
    <gml:Polygon>
      <outerboundaryIs>
        <gml:LinearRing>
          <coordinates>-150,50 -150,60 -125,60 -125,50 -150,50</coordinates>
        </gml:LinearRing>
      </outerboundaryIs>
    </gml:Polygon>
  )

The Geo Module is basically a light-weight wrapper for the JTS Topology Suite: geo:srid calls getSRID() (see [1]). Maybe you could ask on the jts mailing list and give us some feedback?

I am sorry, I did not make myself clear. It always returns 0. There is a way to set the spatial reference. Typically with the srsName attribute on the geometry. In this example that would be the gml:Polygon element. However, none of the valid values is recognized by JTS. It is as if the srsName attribute is not getting to JTS.

Thanks for the hint! I’ll look at this later this day.

According to this: https://github.com/B3Partners/jump-b3p/blob/master/src/main/java/com/vividsolutions/jump/io/GMLReader.java Around Line 202-218 BaseX needs to turn on the capability per line 217-281 (I suggest by default) or allow users to turn it on.

Hi Wray, The project you referenced seems to be a from the original JTS library [1]. If there is an offical JTS branch/fork that provides support for SRIDs, we could think about switching to that version. Best, Christian [1] https://github.com/simplegeo/jts
