I have got an understanding that this is very unmature and the library world is still experimenting.... see below feedback from VIAF yesterday [cid:2992c0a7-c8e4-40f1-8980-3e354e6d4f47] In Sweden the National Library is slowly changing system and the process for Wikidata to support it was some weeks see * SELIBRIS = Wikidata Property:P906<https://www.wikidata.org/wiki/Property_talk:P906> will in the future be deprecated<https://en.wikipedia.org/wiki/Deprecation> * LIBRIS-URI = Wikidata Property:P5587<https://www.wikidata.org/wiki/Property_talk:P5587> after one year VIAF and LIBRIS has nt fixed the flow and are unsure what to do. We started to see problems at VIAF last month when they started to mix ld and new IDs see phabricator.wikimedia.org/T223259<https://phabricator.wikimedia.org/T223… LIBRIS-XL is a projected started in 2012 with focus on Linked data and Bibframe BUT * 7 years later nearly no Linked data * External links like VIAF is strings without a link * 60 000 links Wikidata -> LIBRIS XL<https://www.wikidata.org/wiki/Property_talk:P5587> but nearly no links LIBRIS XL Wikipedia is my feeling * user interface is in Swedish no plans for english has been cmmunicated My feeling is that this is a no win situation and that Wikidata could help Libraries what best practise is... maybe Wikidata is a better hub than VIAF * see my suggestion for Wikimania 2019 in Stockholm T219418#5207385<https://phabricator.wikimedia.org/T219418#5207385> [cid:633c1e51-b69c-48ae-96a9-cf3a64b9719f] Regards Magnus Sälgö Stockholm, Sweden 0046705937579 linkedin.com/in/magnus-sälgö-148890/<https://www.linkedin.com/in/magnus-… ________________________________ From: Wikidata &lt;wikidata-bounces(a)lists.wikimedia.org&gt; on behalf of Thomas Douillard &lt;thomas.douillard(a)gmail.com&gt; Sent: Friday, May 31, 2019 12:27 PM To: Discussion list for the Wikidata project. Subject: [Wikidata] Authority control and Wikidata Hi all, I find it hard to know what are the connections between Wikidata and authority control organizations and big live databases. We got plenty of property that maps entities to external datas in Wikidata, but information about their freshness and the deepness of the collaboration between community and the organisations is harder to find. There is a degree of collaboration, which come from « community does all the work, maintenance and synchronisation, updates on Wikidata are not reflected on the database » to « the organisation fully collaborate and maintains a two way synchronization of the mapping and data from Wikidata (meaning, corrections on Wikidata are reflected on the database and the other way around) ». Do we know where we are on the scale for the major authorities ? Pages like https://en.wikipedia.org/wiki/Wikipedia_talk:Authority_control/VIAF seems to be a little dead, which suggest the collaboration which VIAF seems a little dead right now. Did I miss anything ?
