[OHM] Hangout notes

[Rob H Warren]

For those of you that missed the hangout:

Synopsis:

* Thank you to Tim Waters for bringing back the machine from the dead.
* Connor McManus has volunteered to work on temporal reasoning to link "historic:era" with "key:start_date" when rendering tiles with a specific temporal key.
* There was discussion of current approaches to rendering tiles. Mikel Maron's year specific rendering is a good start but the ideal would be ad-hoc rendering for any date. Part of Jaime Schatz's internship will be to work out a url scheme to signal the tile server what period is desired. Managing the tile server cache is going to be a problem but that can be mitigated using a reverse proxy.
* Susanna Ånäs / Rob Warren will check on importing a set of 'pre-made' time periods using wikidata to be used in a drop-down menu when entering data.
* Tim to setup a github for OHM just to handle project management; this is currently at https://github.com/OpenHistoricalMap/openhistoricalmap
* Rob to send Susanna paper on archival descriptions of maps.
* Jaime to keep working on rendering / ID integration with Rob's help.
* Jerry Skeb has been looking into private library sources for maps.
* Vector rendering will be investigated by Jaime and Erik Theise as a means of lowering the server load.
