RE: Use case requirement 6.13.1

Hmm. As the contributor of the original use-case [1] that triggered this requirement [2] I am concerned that the change of emphasis from 'semantics' to 'structure' changes the goal here. It is precisely the *meaning* that was the concern here. Yes, meaning is tangled up in structure, but it is mostly *semantics*. The point was to support inclusion of precise, fine-grained semantics in a description. The kind of example we had in mind were to allow any or all observed-properties (aka measured-variables), instruments, locations, etc to mentioned in the metadata.

Subject: Use case requirement 6.13.1

Hi all,

Per today's meeting, here is a draft of the PROPOSED wording:

6.13 Describe formal aspects and structure of datasets

6.13.1 Provide recommendations and mechanisms for data providers to describe datasets with a formal description of aspects (e.g. instrument/sensor used, spatial feature, observable property, quantity kind).


The ORIGINAL wording follows for reference.

6.13 Describe fine grained semantics and structure of datasets

6.13.1 Provide recommendations and mechanisms for data providers to describe datasets with fine grained semantics (e.g. instrument/sensor used, spatial feature, observable property, quantity kind).


Rob will check and finalize.
