Regarding Geoserver/Postgis versioning- it’s something that I *really* need to find the time to set up and try, and I’ll certainly report on it when I do.

Portable GIS 2- will hopefully be going out to a select band of testers this weekend, and (assuming it doesn’t require vast amounts of additional work) will be released shortly afterwards. I’m sort of hanging on waiting for the new release of PostGIS and PgAdmin so I can update the PostgreSQL to the latest stable versions, but if they don’t come out very soon I will release it anyhow, and then an update.

Another topic – USB-GIS I have been using it on an 8GB USB stick – flawless.
Is there a bigger version [Portable GIS 2?] ready?
As Mapperz would like to do a blog post on it

Versioning is now available within geoserver. I haven’t played with it (yet) but have seen a really good demo of it, showing transaction history and roll-back support within postgresql/postgis databases (though having just tried to find the link for the stuff I’d seen previously, I can’t). So, it’s not really postgis that does the work, but you have a specially configured postgresql database and then need the versioning extension within geoserver. You can also do some versioning things with the later versions of OpenLayers, using the WFS-T protocol, but again I haven’t had chance to try it out yet. It’s on my list though!

Thanks for stopping by

I attended the workshop you ran in the afternoon on tools for the GI lifecycle and had a question about one of the slides which mentioned “Versioning” as part of an open source toolkit of some description.

I’d be interested in any information you have on this – is this versioning in the same way as ESRI’s ArcServer versions workspaces? If so where is this implemented, as far as I can see PostGIS doesn’t support anything of this nature so curious as to what your slide was referring to here.

Thanks,
