Christophe, The rationale: - Simple URIs - shortening services are a symptom of bad URIs - Previous versions - related to time or not - Works with "file" and "http" - see MED https://joinup.ec.europa.eu/site/med URI examples local file:///foo # latest file:///foo3 # version 3 network http://example.com/foo http://example.com/foo3 Name-dropping :-) I am a friend of Larry Masinter http://larry.masinter.net Long-term archiving is one of his pet subjects http://larry.masinter.net/0603-archiving.pdf Regards Tomas From: Christophe Guéret [mailto:christophe.gueret@dans.knaw.nl] Sent: Tuesday, April 08, 2014 11:24 AM To: CARRASCO BENITEZ Manuel (DGT) Cc: Christophe Gueret; public-dwbp-wg@w3.org Subject: Re: ACTION-10 Possible contribution to the topic from DANS Hoi, Ok. So we may be onto something slightly different then... regarding your example, the temperature in Luxembourg the 2003-04-08 would most likely be fetched out of a preserved data set that contains the daily temperatures. This dataset would be preserved at, say, DANS and contain only "http://example.com/lu" URIs in it (just like every new version of DBpedia still use exactly the same URIs for the resources it contains). Then we would more likely build something like http://example.com/dataset/UUID?http://example.com/lu, the UUID being that of the dataset which contains the description of the temperatures on 2003-04-08. But the two problems I have with this approach are: * The use of a parameter for the request, this makes it easier that trying to split the URI but it not as neat as having just a plain URI. In this respect, we are also looking at the IETF DURI draft (https://tools.ietf.org/html/draft-masinter-dated-uri-10) to provide a nicer dated scheme for URIs. But then we would need a dereferencing service for those DURI who is likely to take them as a GET parameter... so we just shift the issue :-\ * In order to just deliver the preserved data as it was preserved, the description should still describe http://example.com/lu and thus not take into account the fact that it is a different time-located version of the description that is being returned. We could rewrite the description on the fly but that's not a good practice wrt preservation. Maybe embedding the description into another that described the archived resource, and package the whole thing with provenance info would be a good fix there...
