Method to encode the type of values in an Array (the actual data)

[jyucsiro]

How would we encode the type of values in an Array?

• Do we need a special predicate for netCDF-LD?
• Is it important?

Could we look at ISO19115 to see how they encode it? @dr-shorthair

How would http://binary-array-ld.net/latest handle this? @marqh

i think we should consider explicitly handling/specifying data type, it's a useful metadata facet.

we'd need controlled terms for the predicate, we can use http://binary-array-ld.net/latest for that

where could we get a controlled list of terms for known data types?
what should be on this list?

@JimBiardCics and I were discussing and the topic of how would we specify the data type came up. Would we need a register of datatypes? Could we reuse XSD datatypes?

At Sept 29 telecon, we raised that current bald output doesn’t capture datatypes in the RDF encoding which might be important for CF applications. Some libraries - auto-apply _FillValue, add_offset, scale_factor. Need the xsd datatypes to aid tools like nclddump. Bumping this ticket to address the mapping to xsd datatypes on bald

Raise a ticket to add an attribute to an bald:Array for capturing the datatype - bound directly for the file
Optional second statement, e.g. accessedAs

See #67 also.
