I'd like to follow up on some of the comments in this thread. I
apologize for coming to the conversation so late.

Erwan wrote: "Few months ago, I proposed a plan to improve the memory
limits in OpenJUMP using GDMS but without any sucess ;-). "

I would like to clarify this matter with Erwan and the SIGLE Team. I
hope that earlier statements I made were not misunderstood. I wasn't
personally interested in pursuing H2 Database
(http://www.h2database.com/html/frame.html) as a solution for
OpenJUMP's memory limitation. I'm still not personally interested in
this or in any other solution built on a database.

I will point out, however, that this is not a PERSONAL interest of
mine. That doesn't mean that it isn't a valid solution, or something
that OpenJUMP should pursue as a COMMUNITY. I personally don't like to
hassle with the extra layer that comes with database integration,
although I realize databases bring a lot of built-in functionality to
the table. I prefer a file based solution, but I sincerely apologize
if I seemed to speak for the community in this matter. That was not at
all my intention. I'm proud that OpenJUMP is one of the few open
source projects that is truly "community developed". If there is an
individual programmer, or a team of programmers that is interested in
integrating support for the GDMS into OpenJUMP I would fully support
those efforts, even though it is not something I would be involved in
at an intimate level.

I took a few minutes today to look at the links that Erwan had
included in his e-mail on this topic. Some of this work looks very
interesting. I must say that I am disappointed to see what appears to
be yet another open source Java GIS for the desktop, OrbisCAD. But
maybe I don't understand the purpose for the program. I must admit I
had trouble determining the programs purpose from the website. Will
this program be an alternative to UDig and OpenJUMP, or will it do
something different?

I am very interested in any open source code that will allow OpenJUMP
to access DWG and DXF files. Perhaps there is code in GDMS that we can
use? Maybe Erwan would be willing to help us with this?

Would it be possible to expose some of the lower-level functionality
of GDMS to create a framework similar to what we were trying to
accomplish with DataObjects?
This would be an admirable goal.

However, it is important to remember that to be truly useful and
widely adopted I think this functionality needs to be exposed at a
fairly low-level, and not a high-level. (This is just my opinion.)

Still, if I could obtain a generic Feature object using GDMS drivers
from a variety of data sources it would be worth slinging around a
little SQL. :] If we could work together to accomplish this I would
even consider assisting with the maintenance of some GDMS driver code.

I'll leave that offer on the "table". I think it is important for all
of us to share as much code as possible, which was what I was hoping
we could accomplish with the DataObject code. However, if something
similar already exists in the guts of the GDMS, then I would be open
to exposing and using it instead. There is no need to reinvent the
wheel.

I hope to keep plowing ahead on the DataObject implementation with
Paul Austin and other willing souls, but I'd like to hear some more
from Erwan and the SIGLE team. I apologize again if my previous
comments on this matter served to stifle cooperation.
