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
