Show occurrence associations

This ABCD record contains a link to another occurrence. It would be great to show these occurrence relations

Just out of curiosity, how would you approach that ? Considering JME-ETT-03930/726794/374459 is the local id (occurrenceId) in the JMEpiscescoll dataset, how can we get the datasetKey for JMEpiscescoll ?

mdoering commented 7 years ago

the abcd:UnitID of the associated record holds <UnitID>JME-ETT-03930 / 726794 / 374459</UnitID> so we should be able to resolve these.

As for verbatim storage we could use the generic dwc relationship extension with preferred relation types. Food/predator and host/parasite relations are found all over for example.

... the association is within the same dataset

Interesting. Can this be modelled in Darwin Core as well? For Fungi we often have associated taxa as mycorrhizal hosts (symbionts). These could potentially be extracted as separate occurences with associationTypes

I haven't looked carefully at the data, but this sounds like an API issue to begin with - I'm labelling as such
