00:00:07 Ah good. 00:00:12 Cool! http://adbusters.org/campaigns/july4/debate/comments.html 00:00:18 * sbp just wrote up many of his songs, in HTML form, as you can tell... 00:00:21 specifically: http://adbusters.org/campaigns/july4/debate/comments.html?id=3715 00:00:34 but not online! except for that one... 00:00:48 oh, this is your deeley 00:00:53 isn't it hosted on your box? 00:00:59 The logs? 00:01:09 I've been composing songs like that while I walk back from school... quite fun. 00:01:17 I need to produce one for an adbusting movie. 00:01:41 cool 00:01:55 have you written any of the down? Except the /x75 one 00:02:03 No, not really. 00:02:14 They're very much spontaneously improvised. 00:02:36 It's fun tho, the lyrics and rhyming work out surprisingly well 00:02:41 even tho you can't stop and rewind. 00:04:24 * sbp comes up with a convoluted chord sequence... I just can't get it to fit the pattern that I know it should fit 00:05:54 Bm7 Am7(V) GMaj/GMaj7 x 00:05:56 fill in the x! 00:06:23 After learning intervals in music class I can sort of read that! :) 00:06:29 So did you mess any with rdfapi? 00:06:38 I sent a letter to www-archive about it 00:07:14 Ah, I see. 00:07:23 Yes, I realized the comma bug as I woke up this morning. ;) 00:07:44 What else was there... oh yes, equivalence and repr 00:08:29 how do you feed in bNodes??? 00:08:39 Just call Node() 00:08:43 err nod() 00:08:47 err node() 00:08:48 sorry 00:08:48 node() 00:08:55 and feed it what? 00:09:00 Nothing. 00:09:05 It'll return a blank node 00:09:09 http://lists.w3.org/Archives/Public/www-archive/2001Oct/0024 00:09:16 > I'm still not sure how it manages to decode the literal back into a u'' literal, seeing as how there is no reverse function. 00:09:20 Why would you need it to reverse? 00:09:25 Ahh, for output? 00:09:28 yeah 00:09:30 I'll add that... 00:10:19 O.K., so say I was feeding in a triple... I could send it triple.store('x', 'y', ???) 00:10:35 how would I feed it in nothing where the "???" is to get a blank node? 00:10:52 and, what happens when I want to feed in _:b and _:b: labelling the nodes? 00:11:08 store.triple('x', 'y', rdfapi.node()) 00:11:45 so, for :x :y _:b . :y :x _:b . what would I do? 00:12:07 b = rdfapi.node() 00:12:17 store.triple('x', 'y', b) 00:12:23 store.triple('y', 'x', b) 00:12:34 but in practice, I can't do that when parsing an NT document into the store 00:12:50 well, I can, but it'll be tricky 00:13:00 I'll have to create a list of label/node values 00:13:16 Yes, same with output. 00:13:28 Just use a dictionary to do it. 00:13:41 label2Node['b'] = node() 00:14:01 store.triple(label2Node[nodeID], 'a','b') 00:14:44 Why should I define useful namespaces in in the API itself? 00:14:50 wouldn't it be better to make that a separate file? 00:15:14 dunno, just thought it would be neat 00:15:37 I took out the one I did define because I didn't use it. 00:15:40 Feel free to make a file of them for me. 00:15:44 O.K. 00:20:04 * sbp makes NTriples.py RDF API "compliant" 00:20:12 Yay! :) 00:24:51 Boston rocks: http://www.nat.org/camera/dsc03097-800x600.jpg 00:26:03 so... '' is a URI, u'' is a literal? 00:26:07 Yep. 00:26:16 Bijan helped me come up with that trick. 00:26:23 is there a function to convert '' to u''? 00:26:27 in Python 00:26:41 Hmm... let me check... 00:26:46 Hehe, Wes Felter: "I was surprised that the BMW salesman just handed me the keys and told me to bring it back by 6." - Hehe, Wes Felter: "I was surprised that the BMW salesman just handed me the keys and told me to bring it back by 6." 00:26:55 Oops, I meant http://wmf.editthispage.com/discuss/msgReader$5989 00:29:10 * sbp goes looking for the function 00:29:42 sbp, unicode('foo') 00:29:54 >>> unicode('foo') 00:29:54 u'foo' 00:30:06 yep, just got it at the same time :-) 00:30:15 and you can encode as UTF-8... neat 00:30:22 Wes: "I can tell that it would be easy to accumulate speeding tickets in any of these cars." :) 00:33:04 ugh, are you really sure you want to lose the bNode names? 00:33:16 Why is it so important to keep them? 00:33:34 Just indirect to objects thru a dictionary. 00:33:34 aw... it's not 00:33:55 Want me to create a simple function to do it for you? 00:35:31 nodeid2node_map = {} 00:35:32 def nodeid2node(nodeid): 00:35:32 if not nodeid2node_map.has_key(nodeid): 00:35:33 nodeid2node_map[nodeid] = rdfapi.node() 00:35:33 return nodeid2node_map[nodeid] 00:36:34 i've already done that 00:36:42 So why's it so hard? 00:36:46 I'm doing an output function now 00:37:03 Oh... I was going to do that in __repr__... 00:37:09 Well, it just goes the other way 00:37:16 reverse the direction of the dictionary. 00:38:08 yep 00:38:18 * sbp is doing other things at the same time, sorry... 00:38:28 what future do you predict for this API? 00:38:41 I mean: why bother, etc.? Gameplan? 00:38:43 I hope to use it in all my apps, which will eventually take over the world. 00:39:04 > I know, I know: it's an RDF 1.0 API. But is there any chance of a Quad class too? 00:39:04 Umm, it's emphatically not an RDF 1.0 API... and they already are effectively quads. 00:39:10 aha, that's reason enough for me to port my code over 00:39:26 :-) 00:39:41 ah, but they're tacky quads: with statement IDs. I meant quads with contexts 00:39:47 pents, then... 00:39:54 What do you think store() does? 00:40:04 I'm still thinking of the best way to do it though... 00:40:11 Next up is to implement N3 and RDF/XML parsing and them make a cwm-style command-line app. 00:41:49 Want me to do the N-Triples output then? 00:42:38 sbp? 00:42:49 No, I'm doing it now you big lunatic 00:43:00 OK, just asking. :) 00:43:59 ugh, this is a pain in the butt. O.K., when you have a dictionry, can you do for x in dictionary, and what does that return for x? 00:44:26 You probably want for x in dict.keys() 00:44:42 ah, yes, probably 00:44:53 I started this last night and I got this far: 00:44:54 output = '( ' 00:44:54 for t in self.tripleList: 00:44:54 output += '\n\t{ <%s> <%s> <%s> }' % (t.subject.uri, t.predicate.uri, t.object.uri) 00:44:54 output += '\n)' 00:44:54 return output 00:45:10 where self is a store 00:45:31 I've got:- 00:45:31 def printnt(self): 00:45:32 x = '' 00:45:32 self.bNodes = {} 00:45:32 for triple in self.tripleList: 00:45:32 for term in triple: 00:45:34 if not term.uri: bNodes[term] = self.generatelabel(term) 00:45:36 def generatelabel(self): 00:45:38 for bNode in self.bNodes('keys'): 00:46:17 Huh? 00:46:45 oops 00:46:49 s/bNodes/self.bNodes 00:47:14 I'm not sure for term in tripleList will work? 00:47:16 er, and I meant .keys 00:47:40 I meant "for term in triple" 00:49:05 I think it's simpler than that -- whenever you encounter a node that isn't in the dict, just generate a random label for it. 00:49:15 or rather increment the last label 00:49:49 no, because if you match two nodes, then you have to generate the same label for them 00:50:06 Right, which is why you check that it's not in the dit 00:50:08 err dict 00:50:25 but you won't have a dict 00:50:50 Why not... 00:51:16 if not hasattr(t.subject, 'uri') and t.subject not in dict.keys(): 00:51:41 dict[t] = 'a' + str(nodeNum + 1) 00:51:53 ... repeat for preducate, object ... 00:53:31 on second thought, you can do the output function for me :-) 00:53:50 Heheh. I'll write an example you can convert to something more appropriate. :) 00:54:23 well, I've written the NTriples parser, but I have no way of telling if it has worked or not 00:55:03 OK... let me write the __repr_ func... just a sec 00:57:41 how do I get it to print an exception to file? 00:57:53 try: x.parsen(sys.argv[1]) 00:57:54 except: print ??? 00:58:01 look in logicerror.com/archiverProxy-code 00:58:37 search for 'errors.txt' 01:00:23 traceback.print_exception doesn't work... 01:01:05 really? 01:01:12 OK, finished the basic N-Triples stuff, should I upgrade? 01:01:18 Example output: 01:01:18 ( 01:01:19 { } 01:01:19 { _:a1 } 01:01:19 ) 01:01:53 yeah, please 01:03:05 code is really ugly 01:03:18 File "ntriples.py", line 78, in run 01:03:18 try: x.parsen(sys.argv[1]) 01:03:18 File "ntriples.py", line 33, in parsen 01:03:18 f = open(fn, 'r'); self.parse(f); f.close() 01:03:18 File "ntriples.py", line 38, in parse 01:03:19 self.parsent() # Parse self.document into self.quads 01:03:21 File "ntriples.py", line 53, in parsent 01:03:23 self.appendq(line) 01:03:25 File "ntriples.py", line 65, in appendq 01:03:27 if not self.bNodes[bNode]: self.bNodes[bNode] = rdf.node() 01:03:29 KeyError: a 01:03:30 OK, it's uploaded 01:05:09 ... and tests.. 01:09:19 01:09:40 how do I get it to print out? 01:09:42 I have x 01:09:53 x = rdf.Store() 01:09:57 I fed some junk in 01:10:01 print x 01:10:03 I want to print that junk out 01:10:06 ah, neat 01:10:11 very neat :-) 01:10:15 :-) 01:10:52 File "ntriples.py", line 84, in run 01:10:52 try: print x 01:10:52 File "rdfapi.py", line 165, in __repr__ 01:10:52 sub = '<'+t.subject.uri+'>' 01:10:52 TypeError: cannot add type "None" to string 01:11:15 Hmm... 01:11:22 it's in rdfapi, so it's your problem :-) 01:11:27 my end works just fine... ahem 01:11:27 How is it getting None as uri? 01:11:40 bNodes have none as a URI 01:11:49 s/none/None/ 01:12:01 They're not supposed to... 01:12:20 what?! 01:12:20 class Node: 01:12:20 nodeList = {} 01:12:20 01:12:20 def __init__(self, uri=None): 01:12:34 OK, fixed. 01:12:40 * AaronSw uploads 01:13:16 Done. 01:14:00 hooray! 01:14:00 ( 01:14:00 { _:a1 <#b> } 01:14:00 { } 01:14:00 { <#g> _:a1 } 01:14:01 { <#j> <#k> <#l> } 01:14:03 { _:a1 _:a1 _:a1 } 01:14:05 { <#p> <#q> } 01:14:07 { <#t> } 01:14:09 ) 01:14:11 Cool! 01:14:14 Pff: make it output proper NTriples, Aaron... 01:14:27 ah, your bNode output isn't working 01:14:27 Yes, that's a job for the ntriples.py module ;) 01:14:31 the input data is:- 01:14:40 _:a <#b> "c" . 01:14:40 "d" "e" "f". 01:14:40 <#g> "h" _:i . 01:14:40 <#j> <#k> <#l> . 01:14:40 _:m _:n _:o . 01:14:40 <#p> <#q> "\"r" . 01:14:42 01:14:44 "\"s" <#t> "" . 01:14:48 # iophfeia gjpao 01:14:48 Oh, I see the bug. 01:15:57 Fixed in 1003627044 01:17:11 Heh: sbp finds that "a" is too long for rdf:type?
