<p class="MsoNormal">Dear community,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">I like to serve the OpenMath ontologies for the RDF-encoding (<a href="https://openmath.org/om-rdf/">https://openmath.org/om-rdf/</a>) under stable URLs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The ontologies for the mathematical objects and the content dictionaries use the two URLs:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><a href="http://openmath.org/vocab/math">http://openmath.org/vocab/math</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><a href="http://openmath.org/vocab/math/meta">http://openmath.org/vocab/math/meta</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Those URLs do not directly address concrete files but namespaces of vocabularies which may be delivered in different formats (Turtle, RDF/XML etc.).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Currently, as the content at </span><a href="https://openmath.org/"><span lang="EN-GB">https://openmath.org/</span></a>
<span lang="EN-GB">is served via Github pages, it is not possible to redirect <a href="http://openmath.org/vocab/math">
http://openmath.org/vocab/math</a> to the concrete file at <a href="https://github.com/OpenMath/om-rdf/blob/main/ontologies/math.ttl">
https://github.com/OpenMath/om-rdf/blob/main/ontologies/math.ttl</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">To accomplish this, two solutions are possible:<o:p></o:p></span></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-GB">Setup a web server for openmath.org that allows to use URL rewriting to rewrite or redirect from the namespace to the concrete file. As this would impose costs,
I expect that this is no viable solution?!<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-GB">Use w3id.org as proposed in this Github ticket

This would allow us to use URLS like</span><span lang="EN-GB" style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;color:#656D76;background:white"> </span><span lang="EN-GB" style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;color:black;background:white"><a href="http://www.w3id.org/openmath/vocab/math">http://www.w3id.org/openmath/<span style="font-size:11.0pt;font-family:"Calibri",sans-serif">vocab/math</span></a></span><span lang="EN-GB">
for our content.<o:p></o:p></span></li></ul>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Now my question is, if someone has any objections in registering/using</span><span lang="EN-GB" style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;color:#656D76;background:white"> </span><a href="http://www.w3id.org/openmath/"><span lang="EN-GB" style="font-size:10.5pt;font-family:"Segoe UI",sans-serif;background:white;text-decoration:none">http://www.w3id.org/openmath/</span></a>
