This is clearly a good idea.. 14:10:27 <AxelPolleres> That could be expressed in the abstract. 14:11:42 <AxelPolleres> Chime: how can we refere to LinkedData /design issues doc... since it's not a spec 14:11:57 <OlivierCorby> Relevance of linked data wrt to this doc ? 14:12:14 <LeeF> I don't personsally share Tim's view, but I also don't have any objections to this view (so yeah, I agree with Chime and Axel) 14:12:51 <LeeF> I view it as a lightweight, higly portable way to work with RDF data, that's it 14:12:58 <LeeF> s/higly/highly 14:13:26 <AxelPolleres> ACTION: chime to add a statement reflecting TL-1 point 1) in the http-rdf-update 14:13:26 <trackbot> Created ACTION-294 - Add a statement reflecting TL-1 point 1) in the http-rdf-update [on Chimezie Ogbuji - due 2010-08-24]. 14:13:49 <LeeF> (BTW, my regrets next week - on vacation) 14:14:27 <OlivierCorby> 2. direct vs indirect graph manipulation 14:14:49 <AxelPolleres> "I would prefer 4.2 be couched as "Graph Mirroring". This echoes the way many web sites 14:14:49 <AxelPolleres> (and FTP sites) mirror another's contents, and may even provide enhanced access, while not being authoritative. 14:14:49 <AxelPolleres> " 14:15:59 <AxelPolleres> Axel: Graph Mirroring is a use case, but not the only one, we should make that clear in the response. 14:16:29 <AxelPolleres> Chime: hostname/authority was maybe not clear, maybe just needs some rewording 14:16:30 <chimezie> ".. it is often the case (with HTTP graph URIs in particular) that the server associated with the hostname is not the same as the server managing the identified RDF knowledge (as a result of a change in domain name ownership, for instance), the host server is not available, or the URI is not dereferencable" 14:17:58 <AxelPolleres> Chime: general tenor of the mail, is that Tim unerstand the whole document as one use case we have in mind. 14:18:27 <AxelPolleres> sandro: maybe easier, if we respond and try to find some concrete suggestions we can take on board. 14:19:13 <AxelPolleres> "I'd note that it may be useful to have a way of saying that. A simple P label could do." 14:19:42 <AxelPolleres> this sentence not really understandable, maybe ask for clarification. 14:20:21 <AxelPolleres> "so instead of 14:20:21 <AxelPolleres> http://example.com/rdf-graphs/employees?graph=http%3A//www.example.org/other/graph 14:20:22 <AxelPolleres> why not 14:20:22 <AxelPolleres> http://example.com/rdf-graphs/www.example.org/other/graph 14:20:22 <AxelPolleres> or 14:20:22 <AxelPolleres> http://example.com/rdf-graphs/employees/other/graph 14:20:24 <AxelPolleres> " 14:20:36 <SteveH> we need the http/https/urn scheme in there I think 14:21:06 <AxelPolleres> Should we mention both alternatives? I.e. explicityle ecourage masking 14:21:06 <AxelPolleres> the "?" URIs and adding a section that explains why that might be 14:21:07 <AxelPolleres> useful? 14:21:21 <pgearon> I'd like to see ? as an option 14:21:38 <kasei> +1 pgearon 14:21:46 <SteveH> yeah 14:21:47 <AxelPolleres> tim wrote: "A rewrite rule on the server can of course turn this into the "?" form internally and the CGI apparatus fired up as a result." 14:22:28 <pgearon> Many implementations are servlet based, and ? is much easier there 14:22:29 <SteveH> rewrite rules aren't that bothered about ?s 14:22:43 <SteveH> pgearon, really? even with PUT? 14:22:50 <NicoM> for non static graphs, having proxies not cache anything may be a good thing 14:23:11 <LeeF> are proxies that don't cache ? URIs behaving as per spec or are they being naughty? 14:23:16 <AxelPolleres> Axel: Should we explicitly mention the rewrite option in the doc? 14:23:18 <pgearon> SteveH: for me, sure. I'd expect that JS based implementations would prefer ? as well 14:23:26 <AxelPolleres> Chime: wouldn't hurt, can think aobut some text. 14:23:37 <SteveH> pgearon, not really, you have to write your own parser either way 14:25:03 <AxelPolleres> points 4) 5) ... 14:25:56 <AxelPolleres> chime: maybe we should ask back for clarification whether there's specific text he had in mind. 14:26:05 <AxelPolleres> sandro: quicker if we propose text 14:26:09 <AxelPolleres> chime: ok 14:27:31 <AxelPolleres> "...that THE DEFAULT GRAPH OF THE QUERY IS THE ONE IN THE HTTP REQUEST. 14:27:31 <AxelPolleres> Obvious really, but people can miss it." 14:28:52 <AxelPolleres> chime: last TC we need to clarify protocol interaction in general. we can put that in the response 14:29:00 <AxelPolleres> ... ongoing issue 14:29:37 <AxelPolleres> Axel: last point 6) on MS-Author-Via header 14:29:57 <AxelPolleres> Chime: some idea, but not sure what he had in mind 14:30:06 <AxelPolleres> ... ask back for clarification. 14:30:36 <AxelPolleres> ACTION: Chime to draft response for TL-1 14:30:36 <trackbot> Created ACTION-295 - Draft response for TL-1 [on Chimezie Ogbuji - due 2010-08-24]. 14:31:44 <Zakim> - +1.617.245.aaii 14:31:53 <AxelPolleres> topic: issues to be postponed 14:32:58 <AxelPolleres> http://www.w3.org/2001/sw/DataAccess/issues 14:34:06 <SteveH> yes, it was stuff that was left over 14:34:10 <SteveH> we did it by hand IIRC 14:34:16 <SteveH> by we, I mean other people :) 14:34:26 <chimezie> Zakim, mute me 14:34:26 <Zakim> Chimezie_Ogbuji should now be muted 14:35:14 <Zakim> +Lee_Feigenbaum 14:35:24 <AxelPolleres> "alternative limit per resource" http://lists.w3.org/Archives/Public/public-rdf-dawg/2010JulSep/0194.html 14:35:28 <LeeF> the issues list was very much done by hand 14:35:38 <LeeF> zakim, huh?
