[OHM] New to OHM

[Susanna Ånäs]

Would you by any chance be willing to develop the temporal display during
the http://wikilovesmaps.wikimedia.fi/ hackathon? We have representatives
from Sweden, from Riksantikvarieämbetet and Wikimedia Sweden.

There is work around the temporal display done already in this community
and it would be good to gather what has been done, and ideas about how to
proceed.

Cheers,
Susanna

>
> If a building is moved to another location, how would I tag it?
>
> Tagging of historic events such as a battle?
>
> If the exact date of object such as a stone age settlement is unknown, how
> would I tag it?
>
> If I start using custom tags because there is no specified should I add
> them to OHM/Tags in the wiki so they could be discussed/used by other users?
>
> Is the Historical Sources wiki page
> <https://wiki.openstreetmap.org/wiki/Historical_Sources> made for OHM? I
> know tons of datasets that's under public domain. For example
> K-Samsök(SOCH) by the Swedish National Heritage Board has about 1.6 million
> objects with coordinates, I think about 50% of the objects would be
> suitable for OHM and much of the data is available as public domain(I had a
> internship at the Swedish National Heritage Board some years ago).
>
> I'm hoping that I will be able to contribute in different ways to this
> project.
