RE: [Gml4j-devel] IRC discussion for opensource GML development

[Aleksandar M. <ami...@ga...>]

Hi All,

I wouldn't mind participating on the conceptual level, but I will have no
time to do programming myself (unfortunately).

A few comments:
1. The freefs project, VFNY's open-source WFS hosted on SourceForge, already
covers parts of the goals here. It is a WFS and has a SAX GML parser,
although I have no clue if the parser is exactly what you had in mind. Also,
check the license, it may be different from yours.
2. Some IRC time slots are inconvenient for me. For example, 8am in NYC is
5am in Vancouver.
3. Although I am an author of GML4J, I am not convinced that it should be
extended as is. The current implementation is somewhat inefficient in that
it depends on the DOM tree (or rather sits on top of it). It'd be better to
have GML objects that are independent of other object models, but can be
generated, perhaps, from other object models such as DOM. In this sense, GML
SAX parser would be useful.

If you are interested in participating, then let me know:
1. What timezone you are in,
2. What times suite you,
3. What bits interest you.

Email List
========
Discussion of issues is currently happening on the geotools developers list.
http://sourceforge.net/mail/?group_id=4091 . If there is enough external
interest, we may need to move this elsewhere.

Hope to hear from you soon,
Cameron (geotools developer).
