Update EBUCore properties

[jlhardes]

EBUCore has a new version of its ontology that changes some properties and offers new ones to use. For Avalon, when we update the rdf-vocab gem to anything that is 2.2.9 or higher, this means we need to change the following:

Derivative Class

• ebucore:identifier to ebucore:hasIdentifier

Encoding Class

• ebucore:bitRate to ebucore:videoBitRate
• avalon:audioBitrate to ebucore:audioBitRate
• ebucore:hasCodec to ebucore:hasVideoCodec
• avalon:audioCodec to ebucore:hasAudioCodec

Done Looks Like

• Are these changes still the right ones?
• What considerations need to be made before changing these (migration etc.)?

This does need to be investigated still since this issue was created a while ago.

The rdf-vocab gem is now at 3.2.1 and all of the updates listed are still relevant for those ebucore properties (see https://github.com/ruby-rdf/rdf-vocab/blob/develop/lib/rdf/vocab/ebucore.rb for all the properties available through rdf-vocab). This means we can drop some of our custom properties for audio and that we need to update the ebucore properties that we are using since they have changed.

While the latest version of rdf-vocab is 3.2.1, Avalon is using version 3.1.4 right now.

Looks like these ebucore property changes in rdf-vocab are from 2.2.9 forward so they should apply to 3.1.4 as well.
