R: Using Openjump. Obsevations, Ideas, etc (Peppe)

I would add the possibility to save Datastore query definitions
inside JMP files along with "normal" layers.
This would be _very_ useful, at least for me...

Also the Datastore API should be enhanced to support saving.
Even a simple "Save To Datastore..." would be enough
(a real _update_ would be great, but much more difficult to implement).

But maybe OpenJUMP could use a wishlist...
Does it already have one somewhere???

> The main difficulty I found with people is connected

> Some people do not setup well JAVA machine  so
> Openjump does't work. 
> Some other "Windows" people simply don't understand to
> "click on Openjum.bat" file to run Openjump. They
> expect the launcher on the desktop (and .bat still
> remember them the ol'good difficult DOS).
> I started to give people a version of Openjump 1.2B
> with Java embedded, similar to Openjump Merge.
> Proposal: I think it would be fine to have on the web
> site two versions of Openjump: a) one with setup and
> Java embedded for easy people, b) the second one - no
> java no stup - for smart people.

> Openjump is becoming, thanks to edit/drawing tools 
> and SVG export, a good mapping software.  A lot of
> mapping datas are in dwg format and some people cried
> the absence of a dxf/dwg import option. I always
> recomand them the good Michael's dxf plugin. 
> Proposal: If Michael agrees, this plugin could be
> embedded in  Openjump. 
> Regarding dwg I image it is only a problem of time.

> 4) Save file observation.
> There is still some confusion for newcomers about the
> difference betwee "Save Datasets as file..." and "Save
> dataset as..". (See Michael and Uwe discussion in
> [JPP-Devel] Load/Save dataset design). 
> I tried to point out in a help documentation I posted
> some weeks ago. Nevertheless there are still newcomers
> who use "Save dataset as.."  ... and they forget the
> suffix! I belive, like Uwe, that it is important to
> have a suffix built automatically.
> 
> 5) PostGIS
> I think it's time to transalte Uwe's Portgis tutorial
> in English (if Uwe agrees, of coarse) maybe integrated
> with how to use Orbiscad and Openjump together. 
> Proposal: Does somebody thranslate from German to
> English (otherwise this summer I will try to refresh
> my scarse German with Uwe's documentation)?
> 
> 6)Editing tools (not very seriuos!)
> It would be nice to have some editing tools in a
> "Inkscape-like" style. 
> Examples, tranfering some editing tools on the mouse:
> a) one left-click mouse>edit/move object 
> b) two left click mouse>edit/move verticles 
> c) three left-click mouse>free rotation
> This probabiy makes Openjump editing tools more
> "international-ized"
> Is this something difficuld to build?
