Currently there's a datacats issue datacats/datacats#253 addressing the "site_url not persisting" bug, a fix is in discussion. This issue can be closed as soon as the resource proxy and leaflet previews work.
Implement schema decided on in #20 as custom ckanext-harvesting schema.
Create ckanext-harvesting fork once florianm/ckanext-harvesting customisations are merged upstream; until then, use florianm's fork.
Update documentation, send as PR to datacats docs.
Pick and choose from ANZLIC MCP v2 (marine), ?? for terrestrial, plus DPaW nice-to-have fields.
Keep in mind CKAN deliberately keeps metadata simple.
Stakeholders include Landgate, @florianm, @keithmoss with possible input from DPaW, Managing Coastal Vulnerability team (Ralph Talbot-Smith, Chris Barber and Jai).
