<p>[QUOTE=&quot;Ed Snible, post: 4114442, member: 82322&quot;]SPARQL is designed to merge data from different sources.&nbsp; <a href="https://www.cambridgesemantics.com/blog/semantic-university/learn-sparql/sparql-vs-sql/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.cambridgesemantics.com/blog/semantic-university/learn-sparql/sparql-vs-sql/" rel="nofollow">https://www.cambridgesemantics.com/blog/semantic-university/learn-sparql/sparql-vs-sql/</a> .&nbsp; However, many SPARQL implementations use MySQL underneath.&nbsp; Regarding performance and hackery, Wikidata.org has a public endpoint so there must be some way to control throughput.</p><p><br /></p><p><br /></p><p><br /></p><p>I did forget about Tantalus.&nbsp; I just did a password reset and will try it again.&nbsp; I picked two coins and random and although both had a &quot;comment&quot; link no comments were being accepted for either coin.</p><p><br /></p><p>Zeno has a small section for Black Sea area coins you might know at <a href="https://www.zeno.ru/showgallery.php?cat=1285" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.zeno.ru/showgallery.php?cat=1285" rel="nofollow">https://www.zeno.ru/showgallery.php?cat=1285</a> but it isn&#039;t well organized.&nbsp; It is a Russian site and focuses on Asia.&nbsp; I brought it up because I like the hierarchical arrangement, comments open to logged in users on everything, and each category has its own text.</p><p><br /></p><p><br /></p><p><br /></p><p>The ANS is a scholarly institution.&nbsp; The have one guy doing those sites.&nbsp; His blog is <a href="http://numishare.blogspot.com" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://numishare.blogspot.com" rel="nofollow">http://numishare.blogspot.com</a> .&nbsp; The ANS can get papers published in heritage publications discussing data formats.&nbsp; There isn&#039;t anywhere that publishes papers on really slick user interaction.&nbsp; They really are advancing the field for library science and querying heritage data.&nbsp; Eventually they will allow open queries and then people with your skills will be able to come in.</p><p><br /></p><p>The innovations I like to see are about linking data from different sites.&nbsp; 20 years ago I put the most famous book on Greek coins online, then worked with David Surber at Wildwinds to provide a deep link on every page.</p><p><br /></p><p>I believe the rules of CoinTalk ban promoting our own sites, but I want to talk about my site <a href="http://isegrim.mybluemix.net" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://isegrim.mybluemix.net" rel="nofollow">http://isegrim.mybluemix.net</a> .&nbsp; There is an amazing German site with a query interface much more difficult than OCRE.&nbsp; You can find it at <a href="http://isegrim.dasr.de/isegrim/index_en.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://isegrim.dasr.de/isegrim/index_en.html" rel="nofollow">http://isegrim.dasr.de/isegrim/index_en.html</a> .&nbsp; It was started by Ottfried von Vacano in the 1980s.&nbsp; It was the first site with a &quot;Semantic&quot; interface.&nbsp; It only had what you call &quot;God mode&quot;.&nbsp; Not only that, but humans entered coins using an ontology so you could search for &quot;Apollo&quot; but also for &quot;Male&quot; if you didn&#039;t recognize the figure on the coin.</p><p><br /></p><p>I thought it was amazing but none of my collector friends could figure out the weird German query tags, the old-fashioned spelling of city names, or the Latinization of the Greek inscriptions.</p><p><br /></p><p>I spent a weekend doing a modern front-end for it.&nbsp; There are a lot of bugs in the front-end.&nbsp; The thing I am most proud of is nothing on the UI, but that you can share results by copying the URL out of the browser.&nbsp; (I realize Tantalus also has this, but it doesn&#039;t have advanced queries).&nbsp; I also mixed in a little linking with Google Books so if the result is in the British Museum Greek coin catalogs a direct link is provided.</p><p><br /></p><p>The ANS&#039;s underlying platform is good.&nbsp; It would be easy to write an RDF relationship explaining which gods are &quot;male&quot; and which are &quot;female&quot; and allow the ANS data to be queried.&nbsp; The ANS is trying, but they only have a few people thinking about what to do.&nbsp; Read the blog post about adding monograms for Alexander coins to PELLA.&nbsp; <a href="http://numishare.blogspot.com/2019/12/1200-hellenistic-monograms-posted-to.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://numishare.blogspot.com/2019/12/1200-hellenistic-monograms-posted-to.html" rel="nofollow">http://numishare.blogspot.com/2019/12/1200-hellenistic-monograms-posted-to.html</a>&nbsp; It is going to be great.&nbsp; I have some ideas for improving that but don&#039;t know how to contribute.</p><p><br /></p><p>Have you used Pella?&nbsp; Again, my favorite thing about it is the stable URLs. If I want to study an Alexander coin, say for example Price #9, I can go to <a href="http://numismatics.org/pella/id/price.9" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://numismatics.org/pella/id/price.9" rel="nofollow">http://numismatics.org/pella/id/price.9</a> and see examples from the world&#039;s museums.&nbsp; Imagine how handy it would be if your engine, whenever it saw `Price (#)&lt;n&gt;` in the <b>References</b> field made it into a hyperlink?&nbsp; We would rarely need to pull down Martin Price&#039;s book from the top shelf.[/QUOTE]</p><p><br /></p>
