8 National Open Data in Spain Spanish legal framework on Open Data: o Law 37/2007 on the Reuse of Information in the Public Sector Transposition of Directive 2003/98/CE (PSI) o Royal Decree 1495/2011 of Technical Interoperability Standard for the Reuse of Information Resources The Spanish Open Data portal is: datos.gob.es This framework intends to set up a complete set of Interoperability Technical Rules in order to make possible the selection, identification, description, encoding, use and availability of information resources produced or stored in the public sector. 8

9 Datos.gob.es Initiative promoted by the Spanish Government: Ministry of Finance and Public Administrations and the Ministry of Industry, Energy and Tourism, in collaboration with the public company red.es It is the national portal that organizes and manages the Public Information Catalogue of national, regional and local administration The portal also provides an applications catalogue developed by Informed users, educational material and news updates on reusing public sector information. 9

10 Datos.gob.es User profiles: Anonymous Visiting all public areas of the site, sending suggestions, content rating and comments. Public sector managers Add and manage their datasets in the portal (with registration). Entities publish and manage their applications within the portal (with prior registration) 10

11 Datos.gob.es Search support 11

12 Datos.gob.es Every dataset has a detailed description itself Link to the download URL 12

13 Process 1) Extraction of metadata of IGN Catalogue according DCAT profile in RDF: Geonetwork has crosswalks from ISO to RDF 2) Analyze if RDF metadata comply the Spanish Technical Interoperability Standard (NTI) for the Reuse of Information Resources (RISP), which defines a DCAT profile for the Spanish public information catalogues. 3) Fix metadata so it is conformant to NTI-RISP 4) Finally, IGN upload compliant metadata to Data.gob.es portal 13

14 Process Due to NTI metadata items are less than INSPIRE items, it necessary: To include information about licensing with a link Some optional elements are not included because of lack of information in the original metadata o o For instance: actualperiodicity Keywords: We have detected themes which are not included in NTI and mapping of metadata has been necessary Creation of a mapping table aligning INSPIRE themes and NTI themes Identified themes not included in NTI 14

15 How are our records included in the national catalog Open Data? Federated metadata: The customize tool to aggregate records in datos.gob.es. Federation is made possible by accessing a DCAT feed at a known URL on the website of the organization (CNIG) The DCAT feed contains the required metadata as specified in the NTI in a DCAT. Feed Format: ATOM 1.0 RDF/XML 15

17 Conclusions Inspire is part of the data open movement. The metadata in Inspire Catalogue will be part of open data catalogues. Our case is a just example. During the process it has been necessary to modify metadata o The Metadata Catalogue does not support yet the export of metadata conformant to NTI s DCAT profile Next steps: o o o Update our metadata in Open Data catalogue Automate the process to provide the whole IGN metadata to datos.gob.es Analize the feasability of including the resources available in the SDI- Spain catalogue on Datos.gob.es 17
