Cool URIs Don't Change (1998)

Cool URIs Don't Change (1998)
w3.org

So to a large extent this has been mitigated and not using the suggestion here, which is to create a permanent URL ontology upfront

That said eventually neglect, removal, reorgs (or simply websites going offline) still happens... but the way the suggested goal has been advanced is due to becoming a business priority and with redirects and CMSes as tech to help

That said one suggestion made here turned out to be very useful and indeed is the default in WP:

   http://www.w3.org/1998/12/01/chairs

> A reason for using a topic area as part of the URI is that responsibility for sub-parts of a URI space is typically delegated, and then you need a name for the organizational body - the subdivision or group or whatever - which has responsibility for that sub-space. This is binding your URIs to the organizational structure. It is typically safe only when protected by a date further up the URI (to the left of it): 1998/pics can be taken to mean for your server "what we meant in 1998 by pics", rather than "what in 1998 we did with what we now refer to as pics."
