Perhaps you mean "this will be awwsw". 12:53:05 zakim, this will be awwsw 12:53:05 ok, jar286; I see TAG_(AWWSW)9:00AM scheduled to start in 7 minutes 12:57:22 TAG_(AWWSW)9:00AM has now started 12:57:24 +TimBL 13:01:21 +jar 13:01:23 -jar 13:01:23 +jar 13:02:35 timbl has joined #awwsw 13:05:09 Stuart has joined #awwsw 13:05:59 +??P8 13:06:16 zakim, ? is me 13:06:16 +Stuart; got it 13:07:11 alanr has joined #awwsw 13:07:41 +Alan 13:12:00 The TAG had a diagram to express that 13:12:02 jar: suppose that you have a URI that you dereference and different times requesting different language variants. 13:13:00 ... there is something that needs to in some sense be consistent between the returned representations. 13:13:24 http://www.ics.uci.edu/~fielding/pubs/webarch_icse2000.pdf 13:13:48 ... looking for something that 'mandates' such a connection (between representations). 13:14:13 omnigraffle diagram: 13:14:14 http://sw.neurocommons.org/2008/inforesource.png 13:14:18 http://sw.neurocommons.org/2008/inforesource.png 13:14:50 alanr has changed the topic to: http://www.w3.org/mid/27822C0C-4167-4EDE-AF8F-74CA7B4921F7@creativecommons.org 13:15:40 tag:Representation 13:16:18 http://www.w3.org/DesignIssues/Generic.html 13:16:19 Value includes metadata and bits 13:16:31 jar: uses value mean a value that isn't necessarily constrained to be an 'awww:representation' of any particular thing. 13:16:54 u:RepresentationInvariant 13:17:31 q+ to note that Fielding (at least orally) take a utilitarian view of resources. 13:18:35 jar: Fieldings more formal definition of a resource is as a temporal mapping function to sets of equivalent values. 13:19:53 fyi. I think fielding actually says mapping to [sets of equivalent values] or URIs (ie. includes notion of redirection aswell). 13:20:21 he writes "any concept that might be the target of a hypertext link" versus "any web page that might be the target of a hypertext link" 13:21:00 stuart, yes, including URIs is one of the things that makes it inconsistent 13:22:03 alan... how so? 13:23:27 stuart: One inconsistency: Resource = a mapping, versus resource = Any information that can be named can be a resource 13:23:49 a document, an image. These are not mappings 13:25:36 what about differing laws in us, france re: labeling. 13:25:52 If liability is the criterion, then they could have different information 13:26:11 so sometimes = same information, sometimes = same liability 13:26:40 this can be confusing if not predictable, discoverable, at least for machine interpreters 13:26:56 Well... I think that (on the web) I can see a document as a mapping to values (which happen to encode the state of the resource). 13:27:48 stuart, the slogan here is "that's epistemology". One shouldn't confuse how we come to know something from what that thing is. 13:29:31 Now looking at which bit? 13:29:54 q+ 13:30:26 q+ to say the abstract resource is what is denoted. Retract my happiness with the document. 13:30:58 ack Stuart 13:30:58 Stuart, you wanted to note that Fielding (at least orally) take a utilitarian view of resources. 13:31:15 q+ to say the abstract resource is what is denoted. Retract my happiness with the document. The abstract document has the social significance (close to Work) .. the value cloud is a figents imaging hte workings of HTTP 13:31:35 stuart: uri denotes the abstract resource, cloud is a view 13:32:08 stuart: resource proves its utility by being consistent 13:32:54 alan: it's not clear enough 13:33:30 timbl: commonly, we mean the abstract document byt the uri 13:33:42 ... solid line should be denotes, not abused to denote 13:34:19 q+ to ask about uris for ADs that differ only by tag cloud 13:35:14 timbl: you can't provide a complete definition of IR that will satisfy everyone 13:36:36 alanr: 'document' had a prior meaning that was different from AWWW sense 13:37:06 timbl: copyright of language variants is held by same entity 13:38:01 alanr: work, expression, performance are different from doccument 13:38:38 timbl: you can't choose one word that will make all communities happy e.g. library vs. business meann different things by 'document' 13:40:46 for the OWL document, we have a section introducing OWL to different communities (If you are a database developer.... If you are a java programmer ...) If Document is to be used as an effective term, I think we need to have such a thing. 13:41:04 sameWorkAs 13:41:06 jar: can i say sameas for two tag clouds over same AD? 13:41:10 timbl: depends on intent 13:41:36 sameworkas 13:41:59 If it can be sameAs to one community, but not use sameAs in a different community, then doesn't this get in the way of sharing world wide? 13:42:01 I think that you could say that they were variantWorks of the GenericWork. 13:42:24 q? 13:42:28 timbl: can't conclude that A is same as B 13:42:35 ack jar 13:42:35 jar, you wanted to ask about uris for ADs that differ only by tag cloud 13:43:46 people use it all the time 13:44:02 timbl: wouldn't use sameas ... 13:44:07 bycataloge#awww = . 13:44:40 a.com/foo.html = b.com/bar.html ? 13:44:53 <> <> 13:45:09 Xiashou has been using "awww:representation" identifies "awww:resource" with an understanding of "awww:representation" to be an ephemeral thing at a moment... and in that context his "awww:representation" identifies "awww:resource" makes sense. 13:46:05 ex:managedMy [foaf:name "A.com" ] 13:46:06 but the value cloud is dependent on what the server wants to do 13:46:28 two servers serving the same resource don't have to both give the same representations 13:47:00 they only have to give the same representations if they serve the same mime type 13:47:46 http://a.com/foo = http://b.com/bar ? 13:48:10 Alan... what for you makes the resource available at these servers "the same resource"? 13:48:12 timbl: when you refer to it via a particular service, you mean the AD *as managed by that service* 13:49:21 timbl: who is responsible for its upkeep? 13:49:40 timbl: for most purposes we don't care 13:50:06 Oh... another thing on Fielding's model is that there is a two step mapping URI->fn(t); fn(t)->[representation | URI] 13:50:42 Well, we are allowing { ?x ?p ?o } => { ?y ?p ?o } for app p and o. 13:50:44 which kind of acknowledges that the URI->resource mapping can change. 13:51:22 timbl: there is never a complete semantics 13:51:33 Suppose they both are serving a syndicated report of the weather in Oaxaca 13:51:35 jar: but what are ok statements to make? 13:51:45 that was answer to Stuart 13:52:07 stuart, thanks for the picture :) 13:52:13 I'm looking for the kind of objective test that you would use. 13:52:16 timbl: the pdf version has a length of 3.2 kilobytes 13:53:22 Indeed, I would like that too. I think I know how to do that sort of thing, but usually when I try it is considered to formal, or too boundary 13:53:45 s/to/too 13:54:22 timbl: value cloud as a set is not worth talking about 13:54:30 ... because it's hypothetical 13:54:55 ... different ads each time 13:55:12 I think that the value cloud is an artifact of the way that we (Fielding) model a resource (give it a mathematical formulation). 13:55:16 q+ to bring in the question of how we come to know based on the value cloud, and he dependence of the value cloud on the server 13:55:20 ... misleads people into thinking the resource *is* the set of files 13:55:26 ack timbl 13:55:26 timbl, you wanted to say the abstract resource is what is denoted.
