Dear Bernard, As I may not be hard to guess, www.cidoc-crm.org is the home of CIDOC CRM, and the source of ISO21127. I am chair of CIDOC CRM-SIG, a working group of the International Committee for Documentation of the International Council of Museums (ICOM), so I am the right address for your message. The copyright of our work is with ICOM. The redirection from [5] is indeed a feature, and to our best knowledge best practice. If you have can point us to what you expect as the latest state-of-the-art of provenance metadata for RDFS files, we would be very happy. All other copies and versions around are not our responsibility, nor can we prevent people publishing copies or versions anywhere else. Sites accepting submissions such as [1] or [2] should to our opinion at least clarify the provenance of submissions on their initiative. Best wishes, Martin -------- Original Message -------- Subject: Fw: Re: RDF and CIDOC CRM Date: Fri, 14 Jun 2013 18:18:25 +0100 (BST) From: Dominic Oldman <do_home@btopenworld.com> Reply-To: doldman@britishmuseum.org To: Martin Doerr <martin@ics.forth.gr> Fyi Sent from Yahoo!

The draft mentioned by Kingsley [4] is a more recent version 5.1, the xml:base it declares is yet another one [5] which actually dereferences to [6] as [3] does. And the "Erlangen manifestation" [7] mentioned by Richard is yet another avatar, apparently also of version 5.04. You are lost already? Imagine the poor linked data publisher wanting to use the latest, authoritative version of the ontology ... Since none of those vocabularies in their RDF form expose either clear provenance metadata, more recent versions do not mention the previous one(s), you have to look at comments in [4] : "This is the encoding approved by CRM-SIG in the meeting 21/11/2012 as the current version for the CIDOC CRM namespace. Note that this is NOT a definition of the CIDOC CRM, but an encoding derived from the authoritative release of the CIDOC CRM v5.1 (draft) May 2013 on http://www.cidoc-crm.org/official_release_cidoc.html" And from this html page I understand that indeed the 5.04 version is the current official one, 5.1 is just a draft, so after all both namespaces [3] and [5] redirecting to the current "official" version might be a feature and not a bug, but the above comment in the draft about "the current version for the CIDOC CRM namespace" is confusing at least ... If editors of those various versions are around, could they please step forward and clarify what should be used as of today as the authoritative URI and namespace for this important ontology, so that potential users do not need, beyond mastering RDF technologies, a degree in hermeneutics :) Thanks for your time Bernard [1] http://lov.okfn.org/dataset/lov/details/vocabulary_crm.html [2] http://purl.org/NET/cidoc-crm/core [3] http://www.cidoc-crm.org/rdfs/cidoc-crm [4] http://www.cidoc-crm.org/rdfs/cidoc_crm_v5.1-draft-2013May.rdfs [5] http://www.cidoc-crm.org/cidoc-crm/ [6] http://www.cidoc-crm.org/rdfs/5.0.4/cidoc-crm.rdf [7] http://erlangen-crm.org/current/ *Bernard Vatant * Vocabularies & Data Engineering Tel : + 33 (0)9 71 48 84 59 Skype : bernard.vatant Blog : the wheel and the hub <http://bvatant.blogspot.com> Linked Open Vocabularies : lov.okfn.org <http://lov.okfn.org> -------------------------------------------------------- *Mondeca***** 3 cité Nollez 75018 Paris, France www.mondeca.com <http://www.mondeca.com/> Follow us on Twitter : @mondecanews <http://twitter.com/#%21/mondecanews> ---------------------------------------------------------- Mondeca is selected to present at ReInvent Law, London <http://reinventlawlondon.com/> on June 14th Meet us during the European Open Data Week <http://opendataweek.org> in Marseille (June 25-28) -- -------------------------------------------------------------- Dr. Martin Doerr | Vox:+30(2810)391625 | Research Director | Fax:+30(2810)391638 | | Email: martin@ics.forth.gr | | Center for Cultural Informatics | Information Systems Laboratory | Institute of Computer Science | Foundation for Research and Technology - Hellas (FORTH) | | N.Plastira 100, Vassilika Vouton, | GR70013 Heraklion,Crete,Greece | | Web-site: http://www.ics.forth.gr/isl | --------------------------------------------------------------
