Problem: I've no SVN access at OSM. Where could I get it?

Ok, looks nice. Some comments:

- The class tags are still used on the website. Also some OSM
unknown tags like "poi" are used. Is that only because nobody removed
them? Or has gpsdrive an own subset of tags?

- Many not OSM supported icons and types are listed. I would build the
feature/icon database "from the other side". The site lists many icons
not known in OSM and then define OSM tags for some icons. My idea is to
do it the other way. Have OSM tags as "index" and define icons for it.
Similar result, but more logic.

- We should really import that stuff into a database. The frontend to
manage and vote features could be much work, but a script that creates a
simple dynamic page like that on gpsdrive.de should be really easy.

I thought about hacking a small script that generates a website with
these icons. But I'm not sure how to do it. Lets discuss about it,
perhaps someone has inovative ideas.

What are the requirements?

1) Create a database model to fill in all tag information.

  1a) Point to various icons from a tag.

2) Icons should stay in /var/www to be displayed and changed by a

3) Icons should stay in /usr/share/map-icons to be used by applications.

-> I know 3) and 4) are contrasts. I've not yet a clean solution for

-> Currently you put icons into SVN. It may be a problem to write icons
to SVN from a website(?).

4) Create a website from database with tags/comments/icons/...

5) Be able to manage (e.g. vote) the tags/icons with a web frontend.

6) Create a Mapnik XML file from database.

7) Create osmarender definition from DB. (I don't know how osmarender

Any other requirements? Any comments? Any ideas?
