DCAT DatasetSeries

• DCAT Version 3 provisional diagram: https://w3c.github.io/dxwg/dcat/#fig-dcat-all-attributes

• A dataset series (top-level Dataset) contains many datasets which contains distributions describing the new data payload.

• AusPlots Rangelands (DatasetSeries)

  • AusPlots Rangelands January 2021 (Dataset)

    • Payload described as Distribution

  • AusPlots Rangelands February 2021 (Dataset)

    • Payload described as Distribution

DCAT Dataset versioning

• For controlled vocabularies - it depends on the business rule on how we handle versioning.

• Each new version is a new Dataset.

• Special relationships between datasets called previous version or has version. dcterms:relation, DCAT qualified relation

• Top-level Dataset

  • One level down, different versions (also Dataset)

  • dcat:isVersionOf links to the top-level Dataset.

Modelling occurrence

• Quick question about Occurrence modelling in O&M

• Feature type:

  • plant occurrence

    • aka plant aggregate observation

    • opportunistic

  • animal occurrence

    • aka animal aggregate observation

    • opportunistic

  • animal individual

    • Tagged for continuous observations

  • plant individual

    • Tagged for continuous observations

    • E.g., in AusPlots Forests

• “Occurrence” is a mixture of sampling, sample … and observations.

  • An occurrence is recorded as a sampling where the thing is a sub-sample/feature-of-interest

    • Further observations are then made on this sub-sample (e.g., animal-individual)

      • E.g. the taxon identification
