03:03:27 <sethl_lap> most complicated query tested so far: SELECT ?x WHERE (?x, <rdf:type>, <cp:Parameter>), (?x, <cp:parameterName>, ?y), (?x, <cp:parameterValue>, ?z) AND ?z > 20 and ?y == \"TTL\" USING rdf FOR <http://www.w3.org/1999/02/22-rdf-syntax-ns#>, cp FOR <http://www.brivo.com/2002/12/controlpanel#>
03:03:52 <sethl_lap> with new RDQL engine for rdflib
03:05:14 <sethl_lap> I have to wire in the rdf-query testcases now
03:05:23 <sethl_lap> I'm relatively confident that the engine is working

11:16:30 <dc_rdfig> Added comment A1.
11:19:14 <edd> bah, largely recycled from his earlier rants
11:20:09 <dajobe> yes, and now I have to respond
11:21:35 <dajobe> and I have to do it on the web
11:23:04 * edd sighs
11:23:14 <edd> it seems a bit ego feeding for him
11:23:21 <edd> do you really have to make a response?
11:25:08 * edd hopes the query bof going well :)
11:25:53 <tim-budapest> XQuery being adapted to SQL by cacnnonical rep'n of RDBs
11:30:15 <dajobe> rdf query bof...
11:30:37 <dajobe> andys: dusing xml query - be daft to duplicate the work there. take the XPath out and put an rdf graph matcher in
11:30:38 <tim-budapest> Take Xpath out and RDFpath in - you can return stuff which can be RDF, hich is the right way to work (agreement)
11:30:41 <dajobe> xml query returns results that can be formated
11:30:51 <dajobe> so it would be ths same for rdf, want rdf back
11:31:01 <dajobe> Andys^
11:31:13 <dajobe> emiller:
11:31:29 <dajobe> w3c is working very heavily in the area of query
11:31:35 <dajobe> ... lots of mmebers working on thuis
11:31:48 <dajobe> and is importatnt to understand the relationship to that going on in the field with that in the rdf
11:32:00 <dajobe> as long as what ytou described solves this problem in directed labeleg gtraphs
11:32:06 <dajobe> can use the existing framework, seesms symbiotic
11:32:21 <tim-budapest> What paul said to EricM was that a lot of people are working on XQuery..
11:32:24 <dajobe> emiller reproted what paul ? said
11:32:45 <dajobe> ericP: how many peole like the idea?
11:32:54 <dajobe> xquery -xpath +an rdf path
11:32:59 <dajobe> proposal
11:33:03 <dajobe> counting heads in the room
11:33:19 <DanC> poll: "Take Xpath out and RDFpath in - you can return stuff which can be RDF, hich is the right way to work" worth exploring
11:33:20 <dajobe> consensus pretty much that it was worth exploring
11:33:21 <crysflame> mm, xquery with an rdfpath. interesting.
11:33:22 <DanC> many in favor
11:33:25 <dajobe> 2/3 in favour
11:33:36 <dajobe> timbl: i've done that
11:33:44 <dajobe> ... if you take xml query FOR, LET ...
11:33:53 <dajobe> ... WHERE constraints RETURN something
11:34:05 <dajobe> xmlq is based on orderede xml 'FLOWR'
11:34:14 <dajobe> can iterate recursively over the thing, extremely ordered
11:34:24 <DanC> tutorial on cwm paths (and lists) http://www.w3.org/2003/Talks/0520-www-tf1-b-more/
11:34:26 <dajobe> and all process ordered as xml is ordered
11:34:30 <dajobe> DanC: corrects tim on orderering
11:34:42 <dajobe> timbl: if you take out the flowrc clause and remove ordering contrain
11:34:47 <dajobe> then the FOR, LET, WHERE are identical
11:34:58 <dajobe> then you get a ??? you get a WHERE ... RETURN extremely like rdf query
11:35:07 <dajobe> so if you start with xl query, then you gfet up this FLW thing
11:35:20 <dajobe> I'm worried that rdf will head in the same place as the xml syntax
11:35:23 <dajobe> [sigh!!!!]
11:35:32 <dajobe> ... when all we really needs ia where clause
11:35:57 <dajobe> take advanteage of xml query apps, optimising
11:36:02 <dajobe> ... we should develop rdf things
11:36:04 <dajobe> danbri:
11:36:10 <dajobe> <brilliance/>
11:36:34 <dajobe> bwm:
11:37:03 <dajobe> nick (gibbons) was wrong - it is possible to query an rdf graph with xml query??
11:37:18 <dajobe> it may be possible to go beyond that and do some inferenceing
11:37:36 <dajobe> bwm: more important Q - asks tim. Seems it is a no brainer to build bridges back to the xml community
11:37:59 <dajobe> ... you almost seem to be arguing that we shouldn't be looking at all of xml query
11:38:08 <sandro> (that perhaps you can use any query language with inference underneath and the language doesnt change)
11:38:12 <dajobe> timbl: we should look at it and especially look at the functions
11:38:21 <dajobe> ... and not duplicate that. We do need an rdf path.
11:38:41 <dajobe> ericP: when we take out xmlpathj from xmlq, and add an rdfpath
11:38:50 <dajobe> and strip down to FLW or when, wheren, then we have a graph query language
11:39:00 <dajobe> that we can use without that rdfpath - one thing to implemnent
11:39:16 <dajobe> and then above that add xpath to get at some other parts of the document [??]
11:39:22 <dajobe> ... peeking into the literals
11:39:32 <dajobe> We should do the rdf path part and then reuse XMLQuery if we want to
11:39:38 <dajobe> on the reimaining bits such as querying lierals.
11:39:42 <dajobe> benG:
11:40:07 <dajobe> one way to do this is to consider a subset of xml query
11:40:17 <dajobe> and then backend it with an xml query app
11:40:25 <dajobe> rather than deal with low level detail again
11:40:30 <dajobe> such as datatypes
11:40:43 <dajobe> and their functions, list ops etc.
11:41:09 <dajobe> want to work with a free-nough language that optimisers
11:41:12 <dajobe> can deal with
11:41:13 <tim-budapest> q+ to say - mapping RDFQ to XMLQ is straightforward given a canonical (arbitarty) representatoih fo RDF in XML.
11:41:43 <dajobe> some capabilities that are really to do with graphs and not trees
11:41:55 <dajobe> that really won't work with existing xquery impls since they really don't do it
11:42:01 <dajobe> and won't optimise well.
11:42:41 <dajobe> DanC: inx ml query you query the syntax
11:42:47 <dajobe> in rdf, you deal with the domain of discourse
11:42:59 <dajobe> ... most interested in the testing format, can it be expressed in test cases
11:43:14 <dajobe> query WG process can then be measured against those tests - when done these, you are at last call
11:43:29 <dajobe> ... want to continue discussing these tests
11:43:39 <dajobe> and ask about 'can you do these in XML Query'
11:43:46 <dajobe> and see which ones can/cannot be done
11:43:48 <dajobe> .
11:44:02 <dajobe> strawpoll about DanC point above
11:44:07 <dajobe> approx 1/4 in favour
11:44:09 <dajobe> danbri:
11:44:16 <dajobe> good job connecting to xml & xmlq
11:44:19 <dajobe> ^on
11:44:50 <dajobe> translation - the ijndustry is taking things expressed in els & attrs and translatiing into things in the backened database
11:45:03 <dajobe> rdf query needs a good story

11:45:47 <dajobe> maybe we can use the whole thing?

11:46:04 <dajobe> by passing the rdf query around in the xmlq
11:46:05 <libby> B:"This is a response to Libby Miller's comment [1] on RDF query use cases."
11:46:05 <dc_rdfig> Added comment B1.
11:46:16 <dajobe> andys:
11:46:24 <dajobe> going from rdf to xmkl database sounds like a good way to encrypt the query
11:46:38 <dajobe> going from rdf straight to dht e store is a mmuch better and more optimisable way

11:46:50 <dajobe> when I said use the xml query frameowkr, I meant use the conceptual model
11:46:58 <dajobe> as modified for the rdf domain
11:47:31 <dajobe> AndyS: does their approach handling query seem apoproriate for the rdf domain
11:47:34 <edd-lap_> edd-lap_ is now known as edd
11:47:36 <dajobe> then going to the details
11:47:52 <dajobe> danbri: we still may be able to use some of the details
11:48:02 <dajobe> timbl: web page soemwhere on comparing the funcitons [??]
11:48:33 <dajobe> for rdf in an canoical xml form,a ny rdf query can be expressed in an xmlq unless it is incomplete
11:48:44 <dajobe> but the messyiness of the xmlq out depends on your input, mapping
11:48:56 <dajobe> might be worth going through the canonical thing and then
11:49:07 <DanC> on comparing XML Query functions and operators with cwm built-ins, by timb: http://www.w3.org/2000/10/swap/doc/Functions
11:49:08 <dajobe> do the query so that if you want to use your xmlq engine, you can do it
11:49:20 <gromgull> Sorry
11:49:23 <dajobe> timbl: I don't think, like andy, that this will be pretty.
11:49:41 <libby> sorry?
11:49:51 <gromgull> wrong window , sorry :)
11:49:54 <libby> :)
11:49:58 <dajobe> ericP: next item
11:50:59 <dajobe> what to discuss chat
11:51:37 <dajobe> meet again this week?
11:51:54 <dajobe> maybe friday evening?
11:52:16 <dajobe> action ericp: find a room for friday evening
11:52:38 <dajobe> room details to be recorede on the message board by 12:00 friday
11:52:42 <dajobe> and on the ESW wiki page
11:52:55 <DanC> let's meet Friday; EricP to coordinate where; notice to message board, wiki page
11:53:08 <tim-budapest> (uri?)
11:53:09 <dajobe> ericP: 5 mins left
11:53:41 <dajobe> DanC: rs:size
11:54:03 <dajobe> ... only tests I've seen use the files to scope the data
11:54:12 <dajobe> ... in the query language, do you ahve to say this?
11:54:23 <dajobe> the rs:size param is a func of the manifest?
11:54:38 <dajobe> AndyS: some people want to know size of result table since some people want to know that for simple testing
11:54:55 <dajobe> DanC: is it ok, straighforward to take cwm, run q and then not use the count?
11:55:08 <dajobe> AndyS: I don't, I do a graph compare; several others don't either (in theroom)
11:55:11 <dajobe> DanC: great
11:55:17 <dajobe> sandro: are these answers correct?
11:55:21 <dajobe> AndyS: yes, they are
11:55:26 <DanC> I asked if it's ok to compute the count *outside* the query engine
11:55:29 <dajobe> ... with the cobjunctive pattern
11:55:46 <dajobe> sandro: concerned with dup answers
11:56:01 <dajobe> ha sanyone with DQL answers looked at this, notion of equality I expect is different
11:56:03 <dajobe> ?
11:56:27 <dajobe> DanC: no inference allowed?
11:56:55 <dajobe> [too many people talking]
11:57:01 <DanC> (Danbri draws on the whiteboard; anybody willing to take a picture and put a pointer here?)
11:57:18 <dajobe> danbri think we can expand the manifest format
11:57:32 <dajobe> ... to extend to add it to cover when we do rules and inference
11:57:47 <dajobe> AndyS: tricky territory, diff inference engines have different answers from them
11:58:01 <dajobe> timbl: first roll out for the graph matchinging quiery for the test cases
11:58:08 <dajobe> ... then can be used for anyone who defines a particular logic
11:58:20 <dajobe> tests can start with this data and results are *that8
11:58:43 <dajobe> and maybe pick up thje OLW ones
11:58:47 <dajobe> nmg: same as tim
11:58:56 <dajobe> DanC: if you pick up the OWL stuff, you will have infinite counts
11:58:59 <dajobe> ericp:
11:59:15 <dajobe> I bet people who've done this in XSB have thought about this more
11:59:25 <dajobe> [what hafve they done?]
11:59:38 <dajobe> ... for testing if any facts they have... to test their soundness and completness
11:59:56 <dajobe> beng: soundness of the impl or anyh particular rulesset...
11:59:59 <dajobe> ericP: impls
12:00:16 <dajobe> beng: look on sourceforge?
12:00:23 <dajobe> jeen:
12:00:41 <dajobe> beng: they've been around, done some tof this
12:00:49 <dajobe> jeen: sesame does have an RDF MT inferencer, no benchmark on the query level
12:00:53 <dajobe> we do have a test suite on the api level
12:01:08 <dajobe> puts ina bunch of triople, close, computes closure, checks stuff
12:01:10 <dajobe> at api level
12:01:17 <dajobe> smh: 3store does this too
12:01:22 <dajobe> jeen: on ource sourceforge site
12:01:47 <dajobe> ari: typed graph matching people
12:01:54 <dajobe> "sub graph isomorphism" into google
12:01:59 <dajobe> have done this, similar problems
12:02:06 <dajobe> they may have graph datasets
12:02:11 <dajobe> with tests
12:02:20 <dajobe> ari: somebody at NYU
12:02:23 <dajobe> [hunt for google clues]
12:02:36 <dajobe> they must have test suites

14:02:27 <sethl> morning
14:03:02 <libby> sethl, have you been doing query stuff?
14:03:24 <sethl> yup! implementation of RDQL for rdflib, I was going to hand off to eikeon today
14:03:35 <sethl> though, been having hard time defining what RDQL actually is :)
14:03:41 <libby> nice one!
14:03:47 <sethl> it was fun :)
14:03:50 <libby> really? there's a bnf somewhere I think
14:03:55 <sethl> I was looking at SeRQL, too
14:03:58 <libby> are you goign to use the testcase?
14:04:01 <sethl> yeah, inside Jena
14:04:02 <libby> testcases?
14:04:07 <libby> cool
14:04:15 <sethl> I was just looking at them last night, I'm going to try
14:04:24 <sethl> that way, if I pass those, I'll know I'm good w/ the spec
14:04:40 <sethl> i found many things I think are the testcases
14:04:56 * sethl goes to find the URI
14:06:10 <libby> we havve soem query ones - http://swordfish.rdfweb.org/rdfquery/tests/
14:06:19 <libby> though there are lots in jena dist too
14:07:13 <sethl> I found the Jena ones, I wasn't sure which are the "blessed" test cases (query test cases seems a bit overloaded)
14:07:27 <sethl> found this: http://www.w3.org/2003/03/rdfqr-tests/rdf-query-testcases.html
14:07:41 <libby> right
14:08:01 <libby> the actual cases are at the swordfish address (we'll move 'em later)
14:08:15 <sethl> nice, ok, the pieces are coming together...
14:08:23 <sethl> right now I have my own unit tests passing
14:09:05 <sethl> thanks libby, you read my mind :)
14:09:26 <libby> hm, fancy donating them?
14:10:24 <sethl> sure, no prob (they are in pyunit)
14:11:04 <lasse> are there any cool sites on the Internet which one could demonstrate the power of SemWeb/RDF easily?
14:11:19 <lasse> with
14:11:20 <sethl> I see squishtests and rdqltests... are they the same, just different query languages?
14:11:20 <sandro> sure would be nice
14:11:45 <sethl> lasse: lots of people use CWM (python app) to show nifty demos
14:12:26 <lasse> which platform does it run on or do I need a python compiler?
14:12:34 <sandro> there is no cwm web demo, alas. (I tried to write one for this conference, but didnt finish)
14:12:44 <sandro> cwm needs python, yes.
14:12:46 <sethl> any python (2.1 or >) I think is fine
14:12:59 <lasse> wonder if there's python for os x
14:13:04 <sethl> included!
14:13:11 <lasse> darn :)
14:13:16 <sethl> (at least, w/ 10.2)
14:13:27 <sandro> see http://www.w3.org/2000/10/swap/doc for documentation on cwm, including links to installation instructions
14:13:27 <lasse> thanks a bunch, must check it out
14:13:36 <sethl> fun little tool
14:13:57 <libby> thanks sethl

14:15:36 <sethl> ok, just wanted to make sure I'm running the right thing. so, there are a suite of tests for each query language it seems
14:15:44 <crysflame> ^ (different)
14:16:01 <libby> hm
14:16:15 <sethl> but the suites test the same things, yes?
14:16:18 <libby> the plan has been to convert the queries to ntriples, using bnodes as variables
14:16:43 <sethl> how will you express things like rdql's AND in ntriples?
14:16:49 <libby> at the moment, they test probbaly different things - we havn't worked if it's a comprehensive set
14:16:56 <sethl> gotcha
14:17:08 <libby> sethl, we don;t, just the simplest queries for now
14:17:13 <sethl> k
14:17:20 <libby> so oyu may find that some are in ntriples is all I meant
14:18:35 <libby> sethl, tell me if theyare useful to you, or if not, why not :)
14:18:46 <sethl> will do! I'll start w/ http://swordfish.rdfweb.org/rdfquery/tests/tests/rdql-tests-2003-04-10/
14:19:45 <mattb> i just started looking at rdflib a couple of days back
14:19:49 <mattb> anticipating doing some python soon
14:19:54 <sethl> I find it very easy
14:20:00 <sethl> interface is a lot like redland's
14:20:08 <mattb> yeah, seemed nice, python idiomatic
14:20:09 <mattb> any idea when the query engine will be ready?
14:20:27 <mattb> although redland is a lot faster of course
14:20:36 <sethl> you can try it out today I guess. only tested w/ my internal tests, though
14:20:50 <sethl> so real world usage is good
14:21:04 <sethl> I'll write up some docs and send it to eikeon today
14:21:09 <mattb> i'd be happy to have a play as soon as i can find time
14:21:14 <mattb> prolly in some quiet conf session
14:21:19 <sethl> then I'm going to try these test cases
14:21:59 <sethl> the main difference is my implementation of the AND filter. I use python's eval() to do it, so any valid python is valid there.
14:22:16 <sethl> so, you can write AND ?y > 20 and ?x == "foo"
14:22:39 <sethl> or AND ?y > 20 and (?x == "foo" or ?x == "bar")
14:22:45 <sethl> stuff like that
14:22:51 <mattb> interesting stuff
14:23:05 <mattb> it's based on top of rdflib, or a patch to it?
14:23:11 <sethl> it's on top
14:23:25 <mattb> if it uses the simple triple matching api calls, presumably it could use redland too?
14:24:07 <sethl> yeah, next step is to make it work against an interface, and swap out rdf implementations. since redland has the python layer, that will be cool to test.
14:24:17 <mattb> very nice
14:24:36 <sethl> there are only a few integration points, so it should be quick.
14:24:47 <sethl> would that be more useful that wiring in test cases?
14:24:57 <sethl> (there are already pyunit tests for it, though)
14:25:09 <mattb> i'd go for the testing first
14:25:14 <mattb> prove the engine then make it more portable
14:25:30 <sethl> will do, I can always refactor the interface in as I work the tests
14:25:31 <mattb> helps everyone else using the testcases, too
14:25:36 <sethl> true
14:25:40 <mattb> since they are new
14:25:49 <sethl> I gotta say,python makes it fun
14:26:04 <eikeon> ronwolf also wrote a rdflib backend that uses redland... another option for mixing and matching.
14:26:23 <sethl> cool
14:26:36 <dajobe> yeah, I've not seen that code yet from him
14:26:40 * mattb on a big back-to-python swing at the moment
14:26:41 * dajobe summons ronwalf
14:27:53 <eikeon>http://rdflib.net/cvs/rdflib/rdflib/store/RedlandStore.py
14:27:53 <dc_rdfig> G: http://rdflib.net/cvs/rdflib/rdflib/store/RedlandStore.py from eikeon
14:28:01 <dajobe> <eikeon>ronwolf also wrote a rdflib backend that uses redland... another option for mixing and matching.
14:28:11 <dajobe> ah, that's nice
14:28:19 <ronwalf> Yeah, I have to work on that backend a bit
14:28:27 <ronwalf> Some impedance matching to do
14:29:17 <edd> Morbus: yeah, me :)
14:29:19 <ronwalf> Redland has duplicate triples, RDFlib does not
14:29:37 <Morbus> edd: priv msg?
14:29:38 <ronwalf> Redland has contexts associated with each node
14:29:51 <dajobe> G:|RedlandStore.py - python interface for rdflib to Redland
14:29:51 <dc_rdfig> Titled item G.
14:30:05 <ronwalf> RDFLib has returns a list of contexts if you ask it about a node
14:30:14 <dajobe> does it?
14:30:16 <ronwalf> Those are the biggies
14:30:51 <ronwalf> If I remember right, it's something like store.contexts(statement)
14:30:59 <ronwalf> Er, switch node for statements earlier
14:31:31 <eikeon> Sounds right.
14:31:59 <dajobe> where?
14:32:12 <dajobe> oh, redland has ..
14:32:30 <sethl_2> doh, sorry
14:40:33 <chaalsBUD_> grrr network
14:40:36 <chaalsBUD_> libby?
14:40:44 <chaalsBUD_> query which no worky:
14:40:49 <chaalsBUD_> select ?mbox where (http://xmlns.com/foaf/0.1/mbox ?per ?mbox) (http://purl.org/net/inkel/rdf/schemas/lang/1.1#masters ?per it )
14:41:14 * chaalsBUD_ isn't sure if "it" should be quoted, but didn't work either way anyway
14:42:41 <libby> looking now...
14:43:41 <chaalsBUD_> seems to worky now, but doesn't get a result
14:51:00 <libby> chaals - this works: select ?mbox, ?ii where (http://xmlns.com/foaf/0.1/mbox ?per ?mbox)
14:51:13 <libby> it should work in the query itswlf tho
14:51:16 <libby> maybe a bug
14:51:55 * chaalsBUD_ doesn't get what your query does.
14:52:07 <libby> hm, this works too: select ?mbox where (http://xmlns.com/foaf/0.1/mbox ?per ?mbox) (http://purl.org/net/inkel/rdf/schemas/lang/1.1#masters ?per "en")
14:52:18 <libby> I think there was something screwed up with the jsp
14:52:29 <libby> ok now
14:53:04 <libby> hm, no the "it" version doesn;t work
14:53:07 <libby> weird
14:53:53 <libby> oh, no "it" in teh database
14:54:47 <chaalsBUD_> second query no worky for me :(
14:55:01 <libby> which one?
15:42:08 <danq> danq is now known as DanQ
19:22:44 <_joshua> shh
20:34:30 <sethl_2> sethl_2 is now known as sethl
