This means that clients "can use provenance to differentiate between conflicting descriptions as the ontology evolves." It is out of scope for the telecon today to explore exactly what it means to "use as provenance information the ultimate endpoint", so I'd like to start a thread here. Given the examples above...: -- would we want to say that the "ultimate endpoint" be either: -- the name of a file (e.g., "2005-10-31.rdf", as in the example above), or -- a pathname, e.g., http://dublincore.org/2003/03/24/dces#title (which is currently the endpoint of an attempt to dereference the URI http://purl.org/dc/elements/1.1/title)? -- Does what is referred to here as "provenance information" amount, in effect, to "date-stamping" -- using the URI string to convey information meant to be parsed and interpreted as the date on which the URI string was created? If so, would it clarify things to state this more explicitly? -- Is there any reason we might want to recommend the file versus the directory style of date stamping (or indeed a mixed style, e.g. http://dublincore.org/2000/02/26-dctype)?
