clarify parent child relationships

[tomkralidis]

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]

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]

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.

• 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
