ColourSpace

[MarcAntoine-Arnaud]

The ColourSpace is declared as a subClassOf Format.
In the description, it's mentioned it's a free text (so Literal or xsd:anyURI) to reference other definitions.

I think the right way is to define ColourSpace as Literal or anyURI type.

It may ask too rework also that domain.
Regarding SMPTE definitions, Picture Descriptor has 3 parameters (defined by ITU):

• Transfer Characteristic
• Coding Equations
• Color Primaries
  that together defines a ColorSpace.
  For a model like EBUCorePlus, we may expect to have something like:

ec:MediaResource
  ec:hasColorSpace ec:ColorSpace

ec:ColorSpace
  ec:hasTransferCharacteristic anyURI (may include SMPTE UL) or Literal
  ec:hasCodingEquations anyURI (may include SMPTE UL) or Literal
  ec:hasColorPrimaries anyURI (may include SMPTE UL) or Literal
