Martin - could epsg-hsql support this format right now? It does produce a CRS with the ordinates in the correct order ... or does this break our assumptions about "Authority".

I'm not sure to understand. Does epsg.xml#4326 have axis in the (EAST,NORTH) axis order instead of the "official" (NORTH,EAST)?

Even if the epsg.xml#4326 file does not exists, I guess that it is defined in some document? Does the document said something about axis order?

Anyway, to come back on the issue of axis order with epsg-hsql, I realize that some users will wants (EAST,NORTH) order anyway (no matter what the EPSG database said), and that some mechanism may be needed in order to give this control to users. I also suspect that axis order is not the only issue. EPSG sometime uses some particular units like gradians instead of degrees. I guess that some users will want to force usage of degrees for all angular measurements.

One possible approach is to create a wrapper around authority factories. This is the subject of http://jira.codehaus.org/browse/GEOT-694



Evil idea - consider it the "http:" Authority ....

Yes, we can do that. Not sure what the name should be, but I think that considering a new authority may be a good solution.

Right now I'm a little bit stuck with my attempt to create a release. I try to create a release with both Maven 1 and Maven 2 (the later being an experimental release), because I really want transitive dependencies. Maven 2 work well except for the jjtree and javacc plugins (required for building module/main) which are giving me a lot of trouble. Once the release is out, I will look at this axis order issue.
