@Thorsten: The video you mention shows no website nor contact about
the "Marble" project. Could you share more details here? Is it "KDE
Marble" [0]?

@All: Regarding the question about the response format to choose for a
vector tiling server:
* Choosing XML for this does not make sense to me, since human
readability has low priority. There exists the WFS standard from OGC
which covers this.
The use case here demands performance so we should think about a
compact slim format like GeoJSON - or even more compressed.
* Problem: Since we are speaking about "vector tiling" it's
unavoidable that polygons are clipped, which makes me wonder on how
the client is informed and how he should deal with this?

@Michael:
* In the website you refer to [1] there's mentioned "Similar to kothic
js tile format": Why only "similar"? Why don't you not base/fork on
Kothic/KothicJS?
* I'm little bit confused about the project documentation of your
"GSoC - Data Tile Service" since on "GSoc Project Ideas" [2] your name
still is related to the project "Update Monitoring API". And in
"AcceptedProjects" [3] it does not appear. These wiki pages perhaps
need some care.

Yours, Stefan
