The National Center of Geographic Information
The National Center of Geographic Information(CNIG)o CNIG is an autonomous body under the National Geographic
Institute (IGN)
o The main mission of the CNIG is to develop, distribute, market and publish the datasets and productos of the IGN CNIG develops services and metadata according to Inspire
CNIG publish the Spanish SDI geoportal. www.idee.es

Legal framework
Law 14/2010 on the geographic information services and infrastructure in Spaino Transposition of Directive 2007/2/CE (INSPIRE)
o Establishing the National Geographic High Council as National Contact Point and the coordination of the Spanish SDI
o Establishing the National Reference Geographic Equipment: Control points, CRS, GN, AU and Local entities list
o Use and limitations: Geographic services are public and free

Metadata records are compliant to INSPIRE Regulationo A random sample metadata pass the validation INSPIRE
Tool: CatMDEdit Validation INSPIRE

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 ofInteroperability Technical Rules in order to make possiblethe selection, identification, description, encoding, useand availability of information resources produced orstored in the public sector.

Datos.gob.es
Initiative promoted by the Spanish Government: Ministry of Finance and Public Administrations and the Ministry ofIndustry, Energy and Tourism , in collaboration with the publiccompany red.es
“ It is the national portal that organizes and manages the PublicInformation Catalogue of national, regional and local administrationThe portal also provides an applications catalogue developed byInformed users, educational material and news updates on reusingpublic sector information.

Process1) Extraction of metadata of IGN Catalogue according DCAT profile in
RDF:Geonetwork 2.10.2 has crosswalks from ISO 19115 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
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 For instance: actualPeriodicity
Keywords: We have detected themes which are not included in NTI and mapping of metadata has been necessary
o Creation of a mapping table aligning INSPIRE themesand NTI themes Identified themes not included in NTI
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 DCATfeed at a known URL on the website of theorganization (CNIG)
• The DCAT feed contains the required metadata asspecified in the NTI in a DCAT.
Feed Format:ATOM 1.0RDF/XML

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 metadatao The Metadata Catalogue does not support yet the export of metadata
conformant to NTI´s DCAT profile
Next steps:o Update our metadata in Open Data catalogue
o Automate the process to provide the whole IGN metadata todatos.gob.es
o Analize the feasability of including the resources available in the SDI-Spain catalogue on Datos.gob.es
