Hi,
We have some serious issues of running WLM in Finland. Museovirasto (The National Board of Antiquities)[1] has some suitable data. Unfortunately they didn't give us any special permissions to use that, and don't seem to be interested to partner with us. We can only access the data through Paikkatietoikkuna [2] which has very strict rules, including that all data must be destroyed after one year after downloading.
This means that unless something comes up we will not be able to participate in WLM, because we cannot get the data we need in a format we can share.
The only bright side seems to be that they are in process of opening the data even more, so maybe in year or two we could use that.
