The issue that I raised has to do with the possibility that S35 appeals to something that is outside of RDF. Given the response to ISSUE-18, this does not appear to be the case. So maybe this issue has been resolved However, the response below does not appear to address ISSUE-19. peter On 01/08/2015 12:08 PM, Arthur Ryman wrote: > I have updated the wiki [1] with the following additional text: > > This user story is motivated by Linked Data and how information resources > are created (e.g. via HTTP POST) or modified (e.g. via HTTP PUT).
