Data Model

Stub

This page is a skeleton. Content will be filled in during documentation sprints.

Current State

42 active datasets.

Product Types

Controlled vocabulary defined in zenodo_schema.yaml:

dataset, publication, software, presentation, poster, image, video, lesson, physical_object, other

Thematic Areas

Controlled vocabulary defined in zenodo_schema.yaml:

Biodiversity, Climate Change, Ocean Acidification, Marine Protected Areas, eDNA, Invasives, Fisheries, Pollution, Coastal Management, Deep Sea, Coral Reefs, Species Distribution, Near-Realtime

Organizations

OBIS nodes synced from the OBIS API. Prefixed with node- to avoid namespace collisions with groups.

Groups

Research institutions synced from the OBIS API and enriched with Ocean Expert data.

resource_type	Schema.org type (e.g., Dataset, PresentationDigitalDocument)
authors	JSON array of author objects

Data Pipeline

Source API (Zenodo, future: GBIF, Dryad, etc.)
    ↓ mapper (Python function: API response → standard dict)
    ↓
CKAN (storage, curation UI, search, user management)
    ↓ odis_export extension (CKAN dataset → Schema.org JSON-LD)
    ↓
ODIS (discovery, federated search)

Adding a new source requires writing one mapper file in ckanext-doi-import/ckanext/doi_import/mappers/.
