<div>I can envisage it being made easier to, given a WMS or Tile endpoint from an OOC historical map to more easily digitize in OHM. We use the OpenStreetMap tools, but our work flow is probably going to be a bit different in some places.</div>

<div></div><div><br></div><div>My interests in this include both the spatial and temporal, and the joining of those two. A couple of things that might interest: I've done some work with colleague Elijah Meeks on representing historical time (<a href="http://dh.stanford.edu/topotime" target="_blank">http://dh.stanford.edu/topotime</a>), and there is a discussion under way right now in GeoJSON world about adding a "when" object to the forthcoming GeoJSON-LD standard (several threads, listed here: <a href="https://github.com/geojson/geojson-ld/issues" target="_blank">https://github.com/geojson/geojson-ld/issues</a>).<br>
</div><div><br></div><div>I'm very interested in the prospects for developing over time a global historical atlas that includes vector roads and rivers along with cities and boundaries. There are a few schemes aiming at such a thing, therefore many people talking about similar issues but in different conversations. One thing about digitizing is its so time-consuming, getting the "right" encoding scheme down beforehand becomes really important. Not sure how, but merging the discussions somehow makes sense.<br>
</div></div></div></blockquote><div><br></div><div>OHM can take in roads, rivers and anything else that used to exist! It would be great to see the course of a river changing over time, I know there's a fair bit of interest in this within the community.</div>
<div><br></div><div>OHM is evolving in a very OpenStreetMap way - adhoc, community, itch scratchy way. OpenStreetMap tended to avoid worrying about getting the right schema - in favour of a "folksonomy" (With GIS databases, you set the schema first, and then fill in the data, with OSM you fill in the data and make up the schema as you go) Basically it's better to get stuff in the map first and then worry about how to deal with it - I think it's an approach that really works. What that probably means is that the really interesting brain stimulating stuff with vague dates, and fuzzy locations and geographical ambiguity won't be solved before the easy stuff is added and working first. </div>
<div> </div><div>You are correct in that it is time consuming. However in my mind:</div><div> 1) They said the same thing 10 years ago regarding OpenStreetMap and look at it now :-)<br>You are never working alone. Crowdsourcing best practices, Varying sizes of work, durations and community are absolutely key here. Keeping things easy and simple are key in my opinion - otherwise it will be boring. But it's not impossible. </div>
<div> 2) There's the potential to use automated vectorisation for some datasets (See recent discussion on this list) <br></div><div> 3) There's a huge untapped knowledge base of amateur historians, local experts, geographers, databases, archives, libraries and museums all around the world. It's exciting times!</div>

Content-Type: text/plain; charset=us-ascii<br> <br> <br> Figuring all of this is something that will take place in a few iterations. Things to keep in mind: The Gregorian calendar starts around 1582 and anything before is only really valid as a year.<br>
<br> The interface between the slider and rendering was originally meant to be an add-on to the tile renderer with something like startDate, endDate being part of the tile URL.<br> <br> Tim, nice work with the extra layers. What do you think of using TIME-OWL style named time periods to deal with things like "Roman Era" for "historic" tags? This avoids splitting hairs when rendering with dates and help people tag things properly. We can borrow some previous time data from [1].<br>
