clarify parent child relationships #58

While the dataset is the critical path for WCMP2, some users will create child documents, and will require the ability to relate parent/child documents. One option is to consider link relations (up, related, collection, item, etc.) to associate records.

Where would you put this? In the links element which is described as: Online linkages to data retrieval or additional resources associated with the dataset

Or somewhere else?

tomkralidis commented 2 years ago

This would be in the links section. It also assumes infrastructure (i..e the link can be dereferenced). Would there be a case of referencing a parent/child whose metadata is not readily available on the Web?

steingod commented 2 years ago

No I can't see that use case (hope I understood it correctly). I am somewhat concerned on the overloading of this element which can create issues on both creation and parsing though.

TT-WISMD 2023-09-13:

different type of relationships (hierarchy, lineage)
rel=related, we could look into rel=original
we need to be careful not to introduce data hierarchies into the catalogue (granularity)
needs more research
