<P><FONT SIZE=2 FACE="Arial">At the Ottawa GRASS Users Group "OGUG" (</FONT><A HREF="http://cemml.carleton.ca:8080/OGUG"><U><FONT COLOR="#0000FF" SIZE=2 FACE="Arial">http://cemml.carleton.ca:8080/OGUG</FONT></U></A><FONT SIZE=2 FACE="Arial">) we're wanting to host and share community data gathered by, well, the recreational geographer or enthusiastic geomatics tech. Of course once the OSGEO repository is under way there are opportunities to share.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I want to find out different ways people have made collaborative workflows for growing data sets.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I am not a programer but have been exposed to CVS and SVN (my preference right now) for managing source code. Many data types are binary (eg SHP). SVN can deal with Binary but I was thinking something a little more open like GML. Also since GML is just XML text then it can be treated like source code (theory)</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Then I see some scenarios.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">1. Someone can access SVN directory to get latest version.</FONT>
<BR><FONT SIZE=2 FACE="Arial">2. Someone can access the file, add/edit it and then upload a new version. This assumes people won't mess it all up, but we're a small community.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">3. Someone can acess the file, add new data to a new GML file, upload the new GML and a script will append the new GML to the old GML for a new version (I'm not a sys or server admin).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I'm interested in what else has been tried or thought of instead of passing around a bunch of files. I thought maybe an application througha website to a postgis DB, but that's too much for our group to dedicate time to.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">So how can we think of geodata as source code? What am I missing in my thinking?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I guess a GML validation might be good.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">How would this system might work for a binary?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Any ideas?</FONT>
