  1. 1. Bringing Eco-Biological Metadata to Eco-the INSPIRE metainformation world Alessandro Oggioni & Tomáš Kliment GI2011-X-BORDER-SDI/GDI Symposium 23-24/5/2011 BAD SCHANDAU (SAX) # DECIN (CZE)
  2. 2. Outlines • EnvEurope project overview • EnvEurope use cases • Metadata in EnvEurope • EnvEurope&INSPIRE • Crosswalk EML2INSPIRE (ISO) • Conclusions&Future work GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  3. 3. EnvEurope project • Proposes a design for environmental high quality monitoring and long-term research sites • Exemplary establishment of common parameter sets to be collected across LTER Europe network • Based on existing infrastructures = lot of valuable date series • Focuses on 3 types of ecosystems (terrestrial, marine and freshwater) GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  4. 4. EnvEurope project • Aims to select&collect data from E-LTER to provide information on environmental quality in respect of indicators and methodologies applied in main European networks (E-ELTER, EIONET, Natura2000, etc. • Reorganise E-LTER network on the basis of suitable sites, reflecting ecological, political, economic stratification of Europe = will contribute to SEIS and GMES GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  5. 5. EnvEurope project – use cases • 2 user groups • Exchange data • Services • Metadata GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  6. 6. Metadata in EnvEurope • Metadata levels – Site level metadata - LTER InfoBase metadata online entry point – Dataset level metadata – no centralized metadata management tool, no online discoverable metadata – Both levels are important for users GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  7. 7. Dataset level metadata • EnvEurope MD specification development – Reference MD specification – EML – Extent definition - which element for what purposes (discovery, evaluation, use)?&What is required by INSPIRE legislation? – Documentation – UML, element details, XML examples – Implementation – MD management tool • Metadata acquisition and USE GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  8. 8. EnvEurope MD specification Conceptual model – UML class diagrams derived from XML schemas GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  9. 9. EnvEurope MD specification MD elements description tables Metadata element name Dataset title Definition Provides a name of the dataset that is being documented as is known within community. Obligation/condition Mandatory Multiplicity 1 INSPIRE/ISO element 1.1 Resource title/360. Title Example •Density and Biomass of phytoplankton in Lake Candia (1986) Example EML XML encoding <title>Density and Biomass of phytoplankton in Lake Candia (1986)</title> Example INSPIRE XML <gmd:title> encoding <gco:CharacterString>Density and Biomass of phytoplankton in Lake Candia (1986)</gco:CharacterString> </gmd:title> • Totally 20 MD elements defined and described in this way GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  10. 10. EnvEurope&INSPIRE • Domain overlaps defined within 3 INSPIRE data themes • Registration as INSPIRE SDIC • Experts participation within TWG BR-HB-SD • INSPIRE Annex II+III Data Specification Testing participation GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium

  14. 14. Crosswalk EML2INSPIRE (ISO) • Additional rules – Concatenate – Grouping – Constant definition – String joining – Data type definition – Combination of them GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
  15. 15. Crosswalk EML2INSPIRE (ISO) • Implementation – mapping realization in Altova MapForce GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium

  20. 20. Conclusions&Future work • Developed MD specification should satisfy both EnvEurope users&INSPIRE • Partial efforts to bring EML2ISO has been realized • Further mapping has to be done • EnvEurope MD management system has to be implemented • We have to get dirty with MD and collect them GI2011-X-BORDER-SDI/GDIBAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011 Symposium
