what terms are to be used to describe curated links in GBIF between occurrences

[myrmoteras]

GBIF has occurrences that refer in fact to the same occurrence/specimen/sampkle, but cover different aspects of it, such as a physical specimen, a DNA sequence, an observation, a material citation. Many of them are grouped by GBIF as clusters (related records, eg https://www.gbif.org/occurrence/923889551 in https://www.gbif.org/occurrence/923889551/cluster ).

In Plazi, we have a matching service, that uses the clusters from GBIF and then allows the user to curate the links, that is confirm, reject or non-resolvable (because of missing data).

@dagendresen mentioned, that there are terms that we could use to add the link to the matched occurrence, so this link is formally established, at least from a material citation to the respective occurrence.

You may link an organism occurrence to a sample taken using materialSampleID.
You may link organism occurrences of the same organism together using organismID.
You may link organism occurrences of the same observation event together using eventID (and parent eventID if e.g.. from the same experiment or the same field trip, or expedition).
You may create as complex relations as you want using ResourceRelationship (however best practice on how to use ResourceRelationship is debated!).

I just learned, that currently we are storing all three of (a) the link to the materials citation, (b) the link to the GBIF specimen record, and (c) the link to the specimen page at its home institution (if available) ... https://tb.plazi.org/GgServer/html/596E3248AD162638CD24A5EC38D9FCD7 is a good example, with https://tb.plazi.org/GgServer/dwca/A5574A30AD0F2621CE79A4483D39FFA6.zip (specifically occurrences.txt) illustrating the layout:

• the link to the materials citation is in column references
• the link to the GBIF specimen record is in column associatedOccurrences
• the link to the specimen page at its home institution is in column associatedReferences

This way, everyone has the full set of associated links, including the one to the materials citation.
