<html><body><div style="font-family: times new roman, new york, times, serif; font-size: 12pt; color: #000000"><div>Hello all,<br></div><div><br></div><div>I've just now become aware of the OHM effort (hi Susanna) and very interested to learn what the development goals are. Is there a link to some material laying them out? For example, is the plan to provide the means for loading copyright-free scans of historic maps and an editor for digitizing their contents? <br></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">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">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><br></div><div>best<br></div><div>Karl<br></div><div><br></div><div><span name="x"></span><span style="color: #999999; font-size: small;" data-mce-style="color: #999999; font-size: small;" size="2"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">--------------</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">Karl Grossner</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">Digital Humanities Research Developer</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">Stanford University Libraries</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">Stanford,CA US</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;">www.kgeographer.org</span><br style="font-family: Courier New,courier,monaco,monospace,sans-serif;" data-mce-style="font-family: Courier New,courier,monaco,monospace,sans-serif;"><br></span><span name="x"></span><br></div><hr id="zwchr"><blockquote style="border-left:2px solid #1010FF;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="border-left: 2px solid #1010FF; margin-left: 5px; padding-left: 5px; color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><br><div class="gmail_quote"><blockquote class="gmail_quote" data-mce-style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;"> <br> ----------------------------------------------------------------------<br> <br> Message: 1<br> Date: Wed, 14 May 2014 09:19:51 -0300<br> From: Rob H Warren <<a href="mailto:warren@muninn-project.org" target="_blank" data-mce-href="mailto:warren@muninn-project.org">warren@muninn-project.org</a>><br> To: <a href="mailto:historic@openstreetmap.org" target="_blank" data-mce-href="mailto:historic@openstreetmap.org">historic@openstreetmap.org</a><br> Subject: [OHM] TimeSlider - calling attention to early prototype<br> Message-ID: <<a href="mailto:E1B5BD07-1BB0-4947-9C8C-004E29012AF1@muninn-project.org" target="_blank" data-mce-href="mailto:E1B5BD07-1BB0-4947-9C8C-004E29012AF1@muninn-project.org">E1B5BD07-1BB0-4947-9C8C-004E29012AF1@muninn-project.org</a>><br> 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> <br> rhw<br> <br> [1] <a href="http://hypermedia.research.southwales.ac.uk/kos/star/time-periods/" target="_blank" data-mce-href="http://hypermedia.research.southwales.ac.uk/kos/star/time-periods/">hypermedia.research.southwales.ac.uk/kos/star/time-periods/</a><br> <br> <br></blockquote></div></blockquote></div></body></html>
