Hi all,
As discussed in the last meeting, in relation to ISSUE-3 "Role of dcat 
in metadata model <http://www.w3.org/community/ld4lt/track/issues/3>", 
you can find more information of the application profiles of the W3C 
DCAT standard for dataset meta data (http://www.w3.org/TR/vocab-dcat/) at:

https://joinup.ec.europa.eu/asset/dcat_application_profile/description

Specifically, they have produced an application profile for the use of 
DCAT for governmental info in the EU, see:
https://joinup.ec.europa.eu/sites/default/files/8a/71/a0/DCAT-AP_Final_v1.01.pdf

This document explains a lot of the use cases and benefits of using DCAT 
for data set meta-data, so from these it seems clear that many of the 
advantages translate to META-SHARE.

The document represents a good way for how to specify an agreed 
meta-data vocabulary for a class of data sets as a profile of DCAT, i.e. 
in our case for META-SHARE. This involves identifying which classes and 
properties of the model they regard as mandatory and which are optional 
(see section 6 and 7 of the PDF) and also where specific taxonomies or 
type codes should be used for specific attributes (section 8 of the PDF).

In the case of the META_SHARE taxonomy we would simply need to make the 
proposed 'LanguageResource' class a subclass of dcat:DataSet 
(http://www.w3.org/TR/vocab-dcat/#class-dataset) and then work outwards 
from that.

In many cases we are adding new LR-specific attributed to this meta-data.

For some we may be able to replace current attributes with dcat or 
dublin core attributes as specified in DCAT, but then specify the range 
more precisely as in section 8 of the EC application profile.

In some cases, other DCAT classes of Catalogue 
(http://www.w3.org/TR/vocab-dcat/#class-catalog), CatalogueRecord 
(http://www.w3.org/TR/vocab-dcat/#class-catalog-record) and Distribution 
(http://www.w3.org/TR/vocab-dcat/#class-distribution) may be more 
appropriate.

We can discuss this further on the call tomorrow (agenda coming soon).

Regards,
Dave
