17:09:13 [MikeSmith]
alanr: innteresting to hear what the motivation is for in-line datatypes. what would go wrong with just external?
17:09:56 [MikeSmith]
bijan: people don't like having definitions in external file, experience from Protege 3.x
17:10:49 [MikeSmith]
bijan: avoid overhead for always naming types
17:11:52 [MikeSmith]
alanr: is there an argument that necessitates a separate syntax for RDF/OWL?
17:12:16 [MikeSmith]
bijan: the argument is that its not clear tools could find XML Schema syntax in-line
17:12:28 [MikeSmith]
q?
17:12:57 [MikeSmith]
bijan: some argue its more familiar for people from RDF background

17:15:39 [MikeSmith]

acks uli
17:18:42 [MikeSmith]
uli: issue with XML schema types is closely related to using other types in OWL

17:19:07 [bijan]
q+ to reply to uli
17:20:02 [bijan]
I can almost define rationals in xml schema
17:20:16 [bijan]
Definiteately in XML schema + an additional constraint

17:20:44 [uli]
bijan, ...i see - but will they look like the "true" xml schema types?
17:20:50 [bijan]
yep

acks bijan
17:21:25 [Zakim]
bijan, you wanted to reply to uli
17:21:46 [MikeSmith]
alan: concern over defiing, e.g. owl:rational
17:22:19 [MikeSmith]
bijan: owl extensibility requires URIs. owl:rational could be defined, doesn't seem to be a big deal
17:23:12 [MikeSmith]
bijan: clarifying Uli, Alan, are you saying reusing XML Schema syntax might put burden on future datatypes
17:23:25 [MikeSmith]
uli: concern was that other datatypes look like native types
17:23:36 [MikeSmith]
bijan: yes, I believe that they would
17:23:58 [MikeSmith]
bijan: we could use a relax ng type syntax as an inline syntax
17:24:00 [MikeSmith]
q?
17:24:25 [MikeSmith]
acks jjc
17:24:55 [MikeSmith]
jjc: take it that XML Schema types are a given, largely b/c OWL 1.0 supported XML Schema types
17:25:12 [MikeSmith]
jjc: query about how the value space mapping for rational could work
17:25:21 [MikeSmith]
q?
17:26:19 [MikeSmith]
discussion of representation of rational as pair of integers

17:29:19 [MikeSmith]
discussion of XSCD, what they offer, are needed
17:29:55 [MikeSmith]
jjc: the rqmt for us, is less than all of XSCD. we could take less of a solution if it provided re-usable URIs
17:30:22 [MikeSmith]
a query has been sent to the XML Schema WG chair on the status of XSCD
17:32:21 [bijan]
zakim, unmute me

17:33:06 [MikeSmith]
alanr: can we say that if URI is present you can reference external
17:33:08 [bijan]
zakim, mute me
17:33:08 [Zakim]
bijan should now be muted
17:33:24 [MikeSmith]
