I have made the request to generate fsasaki
13:07:11 [tflati_]
dave: some of some metashare properties could be replaced by some dcat properties
13:07:38 [tflati_]
geographic coverage, time coverage, etc. they all have a corresponding property
13:07:58 [tflati_]
penny: about making the language resource
13:08:45 [jgracia]
penny: ms already have a distribution module
13:09:30 [tflati_]
penny: for example the download URL, etc.
13:10:41 [tflati_]
dave: how deep should the separation be made? Are you trying to encourage more than just separation?
13:11:06 [RRSAgent]
I have made the request to generate fsasaki
13:11:21 [Tcarrasco]
13:11:27 [tflati_]
penny: at the conceptual level, i think that usually there are different forms with different licenses

q+ Tcarrasco
13:11:51 [jgracia]
penny: frequently diferent distributions in MS are simply same resource under different licensees
13:12:10 [tflati_]
victor: but they should both allow for distribution
13:13:29 [tflati_]
penny: at least now there is a mix up with dublin core etc.
13:15:35 [tflati_]
dave: we covered both the two points about DCAT
13:17:12 [Tcarrasco]
Data access: record vs. database - URI local vs. remote (file and http schemes)
13:18:11 [tflati_]
penny: i never used SKOS concepts, but I have it like for any classification schema
13:18:26 [tflati_]
not sure how SKOS deals with different dimensions of classification
13:19:13 [tflati_]
we had also a discussion with Marta about subclasses of Corpus and there is no consensus about lexicon or other things, depending several criteria
13:19:29 [tflati_]
the linguality dimension (mono-, bi-, multi-lingual)
13:19:42 [tflati_]
the media type of Corpus (audio, text, etc.)
13:19:57 [tflati_]
one could end up with different taxonomies depending on the used criteria
13:20:35 [Tcarrasco]
13:21:32 [tflati_]
dave: there is not a good model of what a schema should be. Hard to say in a definitive way what is a subclass of what.
13:22:05 [tflati_]
roberto: when we encoded babelnet, we had the issue to see various options. For us SKOS is okay, up to a certain extent
13:22:16 [tflati_]
if you're interested in just a taxonomy SKOS is okay
13:22:44 [tflati_]
otherwise if you want better relations, SKOS might be limited
13:24:13 [tflati_]
we just decided to reduce the granularity of the relations
13:24:33 [tflati_]
we kept the narrower and broader properties for the taxonomic aspect
13:24:42 [tflati_]
and related for all other properties
13:25:15 [tflati_]
jgracia: I think that META-SHARE does not need more expressive properties than those
13:25:28 [tflati_]
Roberto: in this way we also limit variability
13:25:44 [tflati_]
penny: SKOS should be okay
13:26:38 [tflati_]
dave: moving this forward, do we want to separate
13:27:07 [tflati_]
penny: text type, genre, video type would be perfect for the SKOS schema, we could add to them
13:27:31 [tflati_]
dave: yes, i agree. it is part of the issue. There is an involving consensus for the definition of the core
13:27:53 [fsasaki]
action: penny to capture list of parameters that may be relevant for a skos classification
13:27:53 [trackbot]
Created ACTION-12 - Capture list of parameters that may be relevant for a skos classification [on Penny Labropoulou - due 2014-08-07].
13:29:09 [tflati_]
jgracia: the added value of using SKOS rather than OWL?
13:29:15 [tflati_]
dave: you can use both
13:29:16 [RRSAgent]
I have made the request to generate fsasaki
13:30:22 [tflati_]
sometimes one is not sure whether something is strictly a subclass of what
13:30:51 [daveL]
action: pennyl to identify which properties and classes could move to a skos-based conceptual schema
13:30:51 [trackbot]
Error finding 'pennyl'. You can review and register nicknames at <>.
13:30:58 [tflati_]
jorge: narrower could be interpreted in a more loose sense, without being that strict
13:31:11 [tflati_]
present+ pennyl
13:31:25 [jgracia]
so more flexibility in SKOS not commiting to OWL semantics
13:31:29 [fsasaki]
topic: meta-share discussion
13:32:04 [fsasaki]
ack T
13:32:32 [tflati_]
thomas: the access of a record vs. the whole database
13:32:45 [tflati_]
and also the aspect of the access to the schema
13:33:16 [tflati_]
these two aspects have to be considered, also
13:33:25 [tflati_]
dave: this should be included in the distribution module
13:33:43 [tflati_]
because it depends on the media type you are using
13:34:08 [tflati_]
for example if you have a TM you could use a fragment identifier to make the work easily
13:35:33 [tflati_]
thomas: if data can be downloaded, the distribution aspect breaks up because from the application point of view everything is a URI
13:36:11 [tflati_]
penny: this also connects to waht i was discussing with Marta: language resource taxonomy
13:36:34 [tflati_]
the 4 classes of Corpus
13:36:56 [tflati_]
and also a second dimension: the media of resource types
13:37:10 [tflati_]
to MS these are not really subclasses, rather they are parts of a corpus
13:37:18 [tflati_]
that is the reason we called text corpus
13:37:44 [tflati_]
the idea is that you try to put information that describes better the dimension of the corpus into a text file
13:38:23 [RRSAgent]
I have made the request to generate fsasaki
13:38:59 [tflati_]
we might add another class, multilingualcorpus
13:39:13 [tflati_]
the relation subclass should be ispartof, actually
13:39:35 [tflati_]
should be "contains"
13:39:53 [tflati_]
dave: in DCAT you have a Dataset which can have multiple distributions
13:40:09 [Tcarrasco]
We should use the Media Types terminology
13:40:12 [tflati_]
a dataset if a collection of one or more resources
13:40:38 [tflati_]
we might need to use "contains" or "collection"
13:40:44 [tflati_]
of the dcterms collection
13:40:56 [tflati_]
for container of different resources
13:41:22 [tflati_]
marta: it was not my fault to introduce these classes
13:42:11 [tflati_]
the parts should not be seen as collection, but just as a model of having different media types
13:42:18 [tflati_]
not different files
13:43:20 [Tcarrasco]
Multilingual Dataset Format (muset) -
13:43:29 [tflati_]
the corpus is something, how you physically store it is another thing
13:43:45 [tflati_]
this has nothing to do with the implementation/format of your dataset
13:44:25 [tflati_]
dave: terminology is important, one could easily misunderstanf
13:45:15 [tflati_]
thomas: we should use the existing media type terminology
13:45:23 [tflati_]
for example text would be "plain"
13:45:54 [tflati_]
otherwise we have to reinvent it
13:45:54 [chriLi]
I have to leave ...
13:46:45 [tflati_]
we should build on top of IANA
13:47:07 [tflati_]
penny: text is "text", not "plain"
13:47:28 [tflati_]
in the upper level
13:50:13 [Tcarrasco]
according to is "plain text" called "plain" -
13:50:35 [Tcarrasco]
"text" is a whole category -
13:52:50 [tflati_]
I have problems in my internet connection, could you scribe at my place for the next few moments, please?
13:55:27 [daveL]
marta: describes strategy on mapping elements of original meta-share schema into RDF
13:55:49 [Tcarrasco]
in is called "text/plain"
13:56:16 [daveL]
.. in response to vistors question on whther to include 'flat' license attributes in current model, or structure these in ODRL
13:57:45 [daveL]
jorge: this is slightly different from victors questions, since ODRL can represent rules that cannot be represented from the current properties
13:58:01 [daveL]
marta: asks difference between cc model and odrl
13:58:06 [tflati_]
I am back, thanks dave
13:58:39 [daveL]
victor: odrl is more expressive and extensible
13:59:19 [daveL]
scribe: tflati
13:59:37 [tflati_]
victor: maybe not complete, but extensible and flexible for sure
14:01:08 [jgracia]
you have a nice example of ODRL & MS here
14:01:36 [tflati_]
victor: the same resource could have different permissions, depending on the distribution media
14:02:35 [tflati_]
jorge: as for me it is complicated to represent this in ODRL (but only for the machine) and can be done only once
14:02:43 [tflati_]
victor: i completely agree
14:03:38 [jgracia]
but with content negotiation you can reach the simple readable information for humans
