Presentation Transcript

  1. Metadata Maestro Practical (and the new ‘features’ I have found)

  2. Introduction • Metadata Editor • Services • Updates • Keywords – NERC Vocab Server • EDMO Database • Contacts Database • EPSG Database • Projects Page 2

  3. Features • In creating this practical session I have found bugs: • Metadata editor refresh • Template file identifier • Metadata Maestro is supported via MEDIN • There is a programme in place to ensure that bugs are tracked and fixed • Please alert me to any problems you have Page 3

  4. Metadata Editor

  5. Concepts • Profile • Select a profile • MEDIN Discovery Profile (Datasets and Series) • MEDIN Discovery Profile (Services) • Builds a tree of nodes Page 5

  6. Concepts • Nodes • Reflects ISO 19115 structure • Reflects profile names • Indicates obligation of elements Page 6

  7. Red Bar / Green Bar • On the fly metadata validation Page 7

  8. Templates • Create templates for re-use • *.szz file • Some idiosyncrasies (bugs) • File identifier • Identification information Page 8

  9. Templates Page 9

  10. File Identifier • System generated UUID: • Automatically changes for new metadata • Can be saved to a template • CARE – if this is done the same file identifier can be used for all metadata instances based on the template • Delete the file identifier before saving the template • This forces the file identifier to be re-created when the template is loaded Page 10

  11. UUID Creator • Tools > UUID Creator Page 11

  12. KML • Save metadata as OGC KML • http://www.opengis.net/kml/2.2 • Elements mapped: • Resource title -> Placemark name • Abstract -> Placemark description • ISO 19139 XML -> ExtendedData • Geographic bounding box -> Placemark Polygon Page 12

  13. Services

  14. Updates • Local cache: • EPSG Geodetic Parameter (?) • EDMO Database – contacts • NERC Vocab Server – keywords • Online: • GEMET Thesaurus Page 14

  15. Updates • Updates can be: • Automatic at startup • Invoked manually (Tools > Refresh Cached Lists) • Folder: • [user profile]\Local Settings\Application Data\SeaZone\Metadata Maestro Data Page 15

  16. Keywords • NERC Data Grid Vocabulary Server • Different ways of selecting keywords • Search for *water* Page 16

  17. Keyword – Anchor encoding • Care – manually editing keyword lists will not be encoded using the Anchor element <gmd:keyword> <gmx:Anchor xlink:type="simple" xlink:href="http://vocab.ndg.nerc.ac.uk/term/L131/3/AP"> abyssopelagic water column</gmx:Anchor> </gmd:keyword> <gmd:keyword> <gco:CharacterString>water column</gco:CharacterString> </gmd:keyword> Page 17

  18. Contacts • EDMO Database Page 18

  19. Contacts Database • Local contacts database Page 19

  20. EPSG Database • Search for geodetic parameters Page 20

  21. Project

  22. Save Project • Metadata Maestro Project • Saves the state of most open forms • Produces *.szmp file Page 22
