<p dir="ltr">Let me change my statement, "exposing raw RDF is not end-user friendly".</p>
<p dir="ltr">The things with triple tags is that they are supported by the OSM-platform out of the box.</p>
<p dir="ltr">When querying a OHM element you has to parse tags, using a triple tag system for relations allows you to do the same for relations. RDF as a value or tag forces you to implement both tag parsing and RDF/RDF data models(Such as OWL and EDM). </p>

I think that's on the UI/UX failures up to this point. The subject + predicate + object model can be displayed and UI elements designed in a way that makes the representation of relationships easy to document. Autofills with short notations, for instance, solve a lot of the ambiguities of deciding "hmm same_as vs. is_instance_of". I guess what I'm trying to say is that the unfriendliness of RDF to an end-user isn't necessarily or primarily because of the model for assertions but the UIs that have been attempted thus far by non-designers. Also, I think Albin is on the right track by investigating the triple tag/machine tag format (<a href="https://en.wikipedia.org/wiki/Tag_(metadata)#Triple_tags" target="_blank">https://en.wikipedia.org/wiki/Tag_(metadata)#Triple_tags</a>) for expressing complex relationships.<div><br></div><div>Cheers!</div><div><br></div><div>–Tod</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Apr 10, 2015 at 3:50 PM, Albin Larsson <span dir="ltr"><<a href="mailto:albin.post@gmail.com" target="_blank">albin.post@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>I would like to go with the ohm:uri:same_as and a ohm:uri:is_instance_of, the idea it self is based on the idea that a mapper or end user will never see a format such as RDF or JSONLD.</div><div><br></div><div>Your first example would be a is_instance_of.</div><div><div><br></div><div>As I wrote earlier we should support RDF/other formats, but not by force the mapper to use them, ohm:uri:same_as would be equal to owl:sameAs(I think(but has to look into it)) so developers would be translating the tagging to RDF based on a schema we should provide.

<br>
owl:sameAs would allow us to link the object in OHM space to other databases, such as DB/Wikipedia/WikiData:<br>
<br>
Linking the OHM version of say <a href="http://en.wikipedia.org/wiki/Roman_aqueduct" target="_blank">http://en.wikipedia.org/wiki/Roman_aqueduct</a><br>
<br>
Or linking the ww1 trenches within OHM to their Muninn equivalent.<br>
<br>
Or linking greek structures with their pelagios equivalent <a href="http://pelagios-project.blogspot.ca/" target="_blank">http://pelagios-project.blogspot.ca/</a><br>
<br>
Or linking modern administrative locations with their geonames,org location.<br>
<br>
Since a LOD version of OHM will be positioned to be the equivalent to dbpedia in historical GIS terms, the use of owl:sameAs would enable people to discover non-OHM resources since it is the most obvious LOD data set to link to.<br>
