Label Property

[mcdittmar]

Label

• an example from the use cases as to when this would be used would help
• as a free-form text with no ‘role’ or attribute to give it meaning, this definition does not seem very useful
  • if this is for things like Stellar Class, Morphology Class, then I’d expect the value to be from a vocabulary, which would give some context of what the value IS.
    • without this context, the “Label.text” references a column FIELD, and gets a value: Label.text = “M”, what does a user do with this?
• As an AssignedLabel type (if that is what this is): I’d expect
  • value (string)
  • possibly a source vocabulary (where the value came from).. providing description and allowed set
  • or ucd? or something to provide meaning to what the value/vocabulary IS ( value from a Stellar Class vocabulary ) unless the vocabulary itself provides that info. (eg: src.class)

I don't see this in the implementation examples.

I agree, I'll do it
May be a (optional?) attribute to the Label

This is issue is pended until we decide to either remove the Label class or to connect it with a vocabulary

[lmichel]

This property allow to connect labels read in the data table with a vocabulary. This feature (filed - vocab binding) is not supported by the VOtable schema yet. I believe it is useful.
I propose to:

• add a vocabulary URI to the label.
• not to add any UCD which would be confusing with FIELD[@ucd]
