Any thoughts on doing some OpenStreetMap integration?
For those on the list that might not know - Open Street Map is actually rendered in SVG - then uses Inkscape's command level to save to png tiles.
It would be great if we had a GSOC student interested (or anyone else with the time) - it could range from a full fledged editor to maybe something simpler (?) like getting Inkscape to work with lat / long coordinate value translations. 80n at OSM is really interested in this as well

Now to the matter.
I haven't got a clear idea what to do, I'm not even sure about the guidelines for this task nor have a complete feeling of the goal. On the other hand I have some chances to make a piece of valuable work here.
The task was described as "likely XSLT". Fortunately I have the basic understanding of XML and XSLT (I've recently accomplished a subject at my university devoted to XML and XSLT, so I'm quite fresh with it). In addition, I got to like it and feel a need to deal more with such translations.
The fact is, I don't know the "XML Schemas" and practical aspects of SVG and KML. I will need some time to get through their documentations. Anyway, both specifications are worth knowing, so I will gladly learn them.
I guess the job may be considered as import and export respectively. Importing (KML to SVG) shall be relatively simple and with a small risk of an "out-of-time" defeat. The other direction (export) seems more hard and needing deeper considerations. Of course, the importing part might also need some "parameters" (options in import wizard?).
As I am freaky/scarry of not meeting the deadline, I like to find a safe-feeling solution first. An example of such is making a little website for converting KML to SVG using for example Firefox built-in XSL processor (I've used this solution in my last XSLT project, although it didn't involve any SVG rendering). I have then made a silly and tiny web framework (using PHP + .htaccess + mod_rewrite) for passing parameters to the XSLT file (parameters are dynamically inserted into original file as lines with an xsl:param definition each). Thus I could make a small portal driven only by XSLT :-) As this solution is quite comfortable and "recent" for me, I believe "I can make it", and in the meantime we can optionally consider if I will be able to deal with Inkscape internals (that is what I don't know at all, so this may be more risky).
That's it for a minimum. I'm waiting for your opinion and expectations. If you agree for solving this task via XSLT, I'm likely to success with it.
Fantastic that you want to work on this - some of us have talked about the need for this - I'll help you any way I can.
Regarding a work plan - try to break it down into small 1-7 day tasks - approach it in an agile function - so then your goal is to complete at least one task per week.
Actually KML => SVG might not be that easy - Google uses a lot of pre-made objects (such as popups / cloud boxes) that would have to be translated. But again, by taking it in small chunks, you can get a working XSLT translation that can be added to. Also the other direction might have the most impact - being able to draw some nice icons, etc to be added as a map overlay.
But yes, time is running out so get a basic proposal together to make the deadline. We can help you add to it.
