  1. Andreas Schuck Metadata schema, keywords and guidelines NEFIS WP5 Meeting 15-16 November, 2005 Hamburg, Germany

  2. WP 2 deliverables • D3: Metadata standards and keyword lists • D5: User guidelines for the data providers

  3. Metadata Schema (D3) • Tasks: • Preparation of a metadata standard based on Dublin Core Metadata Initiative (DCMI) • Investigating the need to extend the basic DCMI elements structure • Aim: • Test a NEFIS metadata schema and its usability to prepare metadata for the agreed NEFIS data sets • Evaluate through questionnaires its applicability to the NEFIS data sets

  4. NEFIS metadata schema (Part 1)

  5. Element: ’Subject’ refinements NEFISthemes and NEFISterms

  6. NEFISterms – Forest Inventory (extract)

  7. Element: ‘Subject’refinement ‘Nominated Terms’ • Idea: avenue to submit terms not found in the NEFIS controlled vocabulary. • Suggested approach: terms submitted will be subject to editorial review and, if suitable, can be added to the NEFIS controlled vocabulary list.

  8. NEFIS metadata schema (Part 1)

  9. Element: ’Description’ refinement ’Quality Report’ • Need: clearly identifying the quality of an information resource was given high priority by NEFIS partners • Approach: Descriptive text: from resource itself or created by the person creating the metadata. The text can include: • information on mandate for data collection • availability of data collection and processing guidelines (e.g. reference to website or document) • definitions (e.g. a reference to a website or other document) • type of sampling methods • frequency of data collection • explanatory notes

  10. refinement ’Quality Report’ (cont.) • Controlled set of terms to capture crucial elements of quality (example: forest inventory) • Terms • Availability standard error • Standard error • Re-sampling • Re-sampling percentage • Total sample size • Sampling unit

  11. Element: ’Type’ DCMI Type vocabulary Collection Dataset Event Image InteractiveResource Service Software Sound Text PhysicalObject StillImage MovingImage • Encoding Scheme DCMI type vocabulary: • NEFIS addition: • dataset (georeferenced)

  12. NEFIS metadata schema (Part 2)

  13. Element: ’Format’refinement ’reference system’ • Reference System • ReferenceSystemName • DatumName • EllipsoidName • EllipsoidSemi-majoraxis • EllipsoidAxisUnits • EllipsoidFlatteningRatio • ProjectionName • ProjectionZone • ProjectionStandardParallel • ProjectionLongitudeofCentralMeridian • ProjectionLatitudeofProjectionOrigin • ProjectionFalseEasting • ProjectionFalseNorthing • ProjectionLongitudeofProjectionCentre • ProjectionLatitudeofProjectionCentre • Reference system: proposed under element refinement ‘medium’ for in depth details on geo-referenced file extensions • NOTE: For further processing geo-referenced dataset(s) by a user information on name, datum, projection etc. is important • Recommendation: adopt the section ‘reference system’ from EEA document: • EEA metadata form for spatial datasets & EEA metadata standard for geographic information (EEA-MSGI v.1.1), Version 1.2 (08 October 2003)

  14. NEFIS metadata schema (Part 2)

  15. Element: ’Coverage’refinement ’point and box’ • Several methods are available to indicate a place e.g.: • (1) name, (2) geocode, (3) coordinates of a point, (4) rectangular box in two or three dimensions • Identifying a place - the DCMI Box scheme • A place is identified by considering a minimal rectangular box which fully encloses the place andwhose faces are aligned parallel with the axes of an identified cartesian coordinate system. NOTE: Scales of a ‘Box’ can vary. Examples: Europe, region (Umbria), geographic features (Pyrenees), local scale (Wienerwald, forest district, forest stand)

  16. NEFIS metadata schema (Part 2)

  17. Element: ’Rights’refinement ’access rights’ • Information about who can access a resource or an indication of its security status accessRights Public Limited Restricted Restricted – need to be a member Restricted – need to register as a user

  18. NEFIS metadata schema (Part 2)

  19. Element: Audience • Descriptor • business • consultants • donor organizations • educators • environmental groups • financial institutions • forest landowners • forest managers • forestry associations • government • government agencies • media • non-governmental organizations • policy-makers • public • researchers • students • Audience: A class of entity for whom the resource is intended or useful • Mediator: A class of entity that mediates access to the resource and for whom the resource is intended or useful • two basic classes: • an ultimate beneficiary of the resource • an entity that mediates access to the resource (refinement ‘mediator’)

  20. D5: User guidelines for the data providers • NEFIS metadata guidelines elaborated • Guidance document for providing actual data produced • Metadata entry form elaborated based on NEFIS metadata schema
