Enviro grids catalogueskafka

  1. 1. INSPIRE and GEOSS Catalogues Theory and Reality Stepan Kafka, Karel Charvat Czech Centre for Science and Society1 www.envirogrids.cz www.envirogrids.net
  2. 2. You are forcing me to sin, because when using the portal I always start cursing … John, portal end-user2 www.envirogrids.cz www.envirogrids.net
  3. 3. How to avoid it • For end-users operating services are crucial – Availability – Quality of service / data / metadata • Preparing catalogue of „clean services“ to ensure availability • First step - only WMS3 www.envirogrids.cz www.envirogrids.net
  4. 4. Establishment of the catalogue • Harvesting existing catalogues • Catalogues CSW 2.0.2 ISO AP 1.0 • Only services (type=service) • Periodically (P1D) • Sources – GEOSS registry – INSPIRE geoportal – Catalogues we know about • Problems – No central catalogue / we don’t know about services – Classical search engines did not succeed – Many catalogues do not response4 www.envirogrids.cz www.envirogrids.net
  5. 5. 5 www.envirogrids.cz www.envirogrids.net
  6. 6. Harvested catalogues • ISPIRE national nodes: Austria, Belgium, Czech republic, Finland, France, Germany, Luxembourg, Poland, Portugal, Slovakia, United Kingdom • CIDP • EEA SDI • ENVIROGRIDS • EuroGEOSS • GEOSS • Habitats • One Geology Europe • Plan4all • WHO6 www.envirogrids.cz www.envirogrids.net
  7. 7. Service metadata • Problems – poor service metadata (missing abstract etc.) – viewer or web page address instead of service – no mandatory thematic classification in INSPIRE – operatesOn broken links – serviceType not clear7 www.envirogrids.cz www.envirogrids.net
  8. 8. Testing services availability • If Capabilities document is available and valid • Periodically (P1D) • Not valid services are set “hidden”, not erased • Detect linkage in metadata 1. distributionInfo/*/transferOptions/*/onLine/*/linkage http://myservice.com/wms? SERVICE=WMS&REQUEST=GetCapabilities 2. distributionInfo/*/transferOptions/*/onLine/*/protocol OGC:WMS-1.1.1-http-get-capabilities 3. identificationInfo /*/containsOperations/*/ connectPoint/*/linkage8 www.envirogrids.cz www.envirogrids.net
  9. 9. Testing avalability of services • Tools for service provider feedback – RSS channel – Automatic mail notification – “Heartbeat” record9 www.envirogrids.cz www.envirogrids.net
  10. 10. „Heartbeat“ protocol10 www.envirogrids.cz www.envirogrids.net
  11. 11. Results • 2222 services harvested • serviceType (all / valid) – WMS = 96 / 88 – OGC:WMS = 1418 / 1351 – view = 343 / 190 – View = 1 / 1 – VIEW = 2 / 2 – View Service = 76 / 76 • All WMS : 1860 / 1632 (87 %)11 www.envirogrids.cz www.envirogrids.net
