h1. EEA SDI: SDI - The EEA catalogue of geospatial datasets basics h2. 1. Why the SDI? * Discover and access easily EEA data easily both from inside (EEA staff) and outside (ETC, contractors, general public) * Maintain a reference version of datasets produced and/or published by the EEA * Need to have a persistent archiving of the datasets not altered over time * Ensure traceability from final products to source * Identify what exists and what is missing A presentation with all the details about the SDI, components, processes and outlook is available in the attachment:"20180125_SDI_Basics.pptx" h2. 2. Overview of the SDI components h3. Metadata catalogues * The EEA SDI is based on a metadata catalogue service that facilitates the discovery of the datasets produced and/or published by the EEA. * Through the metadata, users can access information on the content and quality of the datasets, and ultimately download the datasets. * The SDI catalogues are accessible through http://sdi.eea.europa.eu/ * Two metadata catalogues describing spatial data published by the EEA: > Internal catalogue: https://sdi.eea.europa.eu/internal-catalogue/ > Public catalogue: http://sdi.eea.europa.eu/catalogue/ > > The public catalogue is accessible by anyone, contains the same records as the internal but with less detailed information. The public catalogue does not provide either access to restricted use data. Names of individuals and file location are removed * A metadata editor is available in order to help create metadata according to the EEA metadata guidelines (see 3). > Metadata editor interface available on: https://sdi.eea.europa.eu/editor-catalogue/ * The SDI catalogues follows the OGC CSW 2.0.2 standard and INSPIRE Discovery services and are implemented using GeoNetwork. Metadata are compliant with ISO19115/19139 and INSPIRE Metadata Implementing Rules. h3. CSW interfaces * Internal Catalogue: http://sdi.eea.europa.eu/internal-catalogue/srv/eng/csw? > Information about the internal catalogue service (GetCapabilities):https://sdi.eea.europa.eu/internal-catalogue/srv/eng/csw?service=CSW&version=2.0.2&request=GetCapabilities * Public Catalogue: http://sdi.eea.europa.eu/catalogue/srv/eng/csw? > Information about the public catalogue service (GetCapabilities):http://sdi.eea.europa.eu/catalogue/srv/eng/csw?service=CSW&version=2.0.2&request=GetCapabilities * (A subset of) the public catalogue is harvested by the GEOSS (Global Earth Observation System of Systems) and available through the GEOSS portal www.geoportal.org > Virtual CSW interface: http://sdi.eea.europa.eu/catalogue/srv/eng/csw-geoss? > Information about the public catalogue service harvested by GEOSS (GetCapabilities): http://sdi.eea.europa.eu/catalogue/srv/eng/csw-geoss?service=CSW&version=2.0.2&request=GetCapabilities > To be harvested by GEOSS it is necessary that the dataset metadata are tagged with the category *geodatacore*. Only *full, free and open datasets* can be tagged as geodatacore. * An interface is available for INSPIRE > Virtual CSW interface: http://sdi.eea.europa.eu:/catalogue/srv/eng/csw-inspire? * RSS feeds are available both for internal and external catalogues: > Internal RSS feed: https://sdi.eea.europa.eu/internal-catalogue/srv/eng/rss.search?sortBy=changeDate > Public RSS feed: http://sdi.eea.europa.eu/catalogue/srv/eng/rss.search?sortBy=changeDate > RDF interface: http://sdi.eea.europa.eu/catalogue/srv/eng/rdf.metadata.get? * SDI API: https://sdi.eea.europa.eu/editor-catalogue/doc/api/ h3. Data storage * Datasets are stored in a file system and a spatial database running on Linux. > Spatial database: PostgreSQL and PostGIS > File-based storage system accessible via CIFS (internally) and HTTPS, WebDavS and FTPS (externally). * The metadata records point to the location of the dataset on the EEA SDI file system. * This repository should contain the “reference” version of any EEA spatial dataset (published or not) used in EEA products. * Datasets are to be versioned – not to be deleted or edited. Data are regularly backed-up. h2. 3. EEA Metadata Guidelines EEA metadata for spatial datasets shall be compliant with ISO 19115 (ISO Standard on Metadata) and ISO/TS 19139 (ISO Technical Standard on Metadata - XML Schema Implementation) as well as with the INSPIRE Metadata Implementing Rules and the Technical Guidelines version 1.3 (http://inspire.ec.europa.eu/documents/Metadata/MD_IR_and_ISO_20131029.pdf). The current guidelines on how to fill in metadata elements are available on this wiki page: [[https://taskman.eionet.europa.eu/projects/sdi/wiki/Cataloguemetadata_guidelines]]. The EEA SDI Team is currently working on updating the EEA Metadata profile to ensure it is fully aligned with the INSPIRE requirements. Accordingly, an updated version of the metadata guidelines are under preparation. In case you have any question, doubt or suggestion, please contact the EEA SDI team on *sdi@eea.europa.eu*Go to top
