<p>Hendrik,</p>
<p>You get GML for free if you similarly abuse GeoServer to serve the vectors. If your vectors are partitioned by image (each with their own coordinate system) you can get plenty of mileage out of a GeoJSON doc and and OL's fixed HTTP strategy. You can find OL examples of editing vectors via JSON in a web mapping framework called MapFish.</p>
<p>I found it easy to work with Djatoka in real world units instead of pixel units. You might have to work in fractional meters unless you extend OL and add µm to its list of supported units.</p>
<p>Cheers,<br>

<br>
thanks everyone for the comments. So far I have experimented with a<br>
Zoomify layer and a few editing controls and got really promising<br>
results. I'm all excited. OpenLayers rocks!<br>
<br>
OL/Zoomify seems to handle pixel coordinates well. I'm still<br>
struggling to teach it micrometers instead of pixels... will need to<br>
have a closer look at the docs I suppose. I will definitely look into<br>
tile servers such as iipimage and djatoka, as well as into gdal2tiles.<br>
<br>
I think most of the work on my side will be about serving and storing<br>
vector content on the server side. GML is probably okay for me, even<br>
if I feel a bit strange about using a "geographic markup language" for<br>
my non-geographical application. I will also need to write some custom<br>
event handlers for drawing on the client side: I need a freehand style<br>
drawing tool, as well as ellipse and circle tools.<br>
<br>
Is there any piece of developer documentation that you would recommend<br>
apart from the APIs, such as books?<br>
<br>
Again, thanks for your input. If I proceed with the project, I'm<br>
hoping to finally contribute code back to OpenLayers as far as<br>
possible.<br>
<br>
bye<br>
