Hi Victor! I definitely think that we (the Linked/Open/(Closed) Data community) need such a profile. Although there are already some languages which offer the possibility to represent access rights/licenses/policies/.. as you pointed out, they usually only focus on specific parts of the challenges you mentioned (e.g. L4LOD for licenses). To overcome this issue a standardized way to represent licenses, access policies/restrictions together with constraints and duties is - in my humble opinion - necessary (e.g. like the Provenance Ontology[1] for provenance information) and I would love to participate in such an undertaking! best regards, simon [1] http://www.w3.org/TR/prov-o/ -------- Original Nachricht -------- Betreff: ODRL Profile for Linked Data Datum: Wed, 17 Sep 2014 00:18:53 +0200 Von: Víctor Rodríguez Doncel <vrodriguez@fi.upm.es> An: <public-odrl@w3.org> <public-odrl@w3.org> Dear ODRL community, In the last months a growing number of voices within the Semantic Web community has claimed for a licensing language for Linked Data and data in general. First, there is a vast amount of open data provided by public institutions whose open licenses are demanded in a digital format. Second, the economical value of some Linked Data datasets is being now recognized, and there is the need for a language to publish offers with a price and richer conditions. Third, access to Linked Data is being normalized, and if there are to be access control systems, expressive policies specific for Linked Data will also be required. These needs can be addressed by using ODRL if properly extended. Therefore, we make a call for a proper ODRL Profile for Linked Data to exist. We do not start from the scratch, there is a breeding ground. Different initiatives to define a language to license data have arosen [1-4] where RDF has been the language of choice. While the terms in LDR [1] have been directly derived from the ODRL Ontology, the rest of them are in essence also compatible with the ODRL schema. Thus, I wonder... Is there enough support or interest to specify such a profile? If this is the case, I suggest we start collecting requirements and features the new language should cover.
