Re: [Vtd-xml-users] HowTo use Vtd for GML to Java Mapping?

[Fernando G. <fer...@gm...>]

Hi All,

Maybe this is a topic for other list... but anyway:

Geotools provides an abstraction to access GML 2.x sources. The problem is
that it provides sequential and read only access. There are some other
projects that access GML in some way. I know Open Jump, gvSIG, kosmo.

If the GML files you have to read aren't very big and you don't have to
access a lot of them simultaneosly, maybe some of the solutions I have
mentioned may work.

Pete, I don't know how much experience you have in GML (I'm quite a
beginner), but I think GML is very complicated to do a parser from scratch.
Currently I'm involved in gdbms (
http://geosysin.iict.ch/irstv-trac/wiki/GDBMS/TechnicalIssues,
http://gdbms.sourceforge.net) which is a general purpose library to
read/write different types of sources. I'm trying to build a GML driver for
gdbms and that's why I'm in this mailing list but I have the will to reuse
parsers from the mentioned projects as much as I can.

By the way, I would like to know what "mailing list suggested vtd". Can you
tell me?

greetings,
Fernando
