[Gvsig_english] Eclipse RCP with gvSIG

Fri Apr 8 13:31:51 CEST 2011

Hi Tobias,

First of all I advice you to decide which version of gvSIG to use. There 
are some important changes between the 1.x and 2.x branches, mainly at 
the data access level and other base libraries.

The 1.x branch is the stable branch now, with the 1.11 version almost 
ready. I think this is the most interesting one if you were going to add 
some functionality and distribute it in addition to the one provided 
with the gvSIG application.

The 2.x branch is now performing an initial stabilization process to 
prepare the final 2.0 version. Not all plugins available in 1.x are 
going to be available initially when it is ready, but most of them will. 
IMHO, this the more interesting one if you can wait a bit, won't need 
the funcionality of those plugins, or if you are going to work at the 
libraries level, as it seems is your case.

Why? Because it is easier to use those libraries, some of them have a 
more delimited API, and more important, there is or will be more 
developer's documentation about them:

http://www.gvsig.org/web/projects/gvsig-desktop/docs/devel

Part of it is already available in English, hope that will grow over time.

Just for curiosity, could you tell us a bit about what are you going to 
develop with gvSIG? If you are allowed to do it, of course.

Regards,
