OLAC Best Practice for media type

Prerecording

Recording

Recording an unstructured description

Recording a structured description

Option

Follow LC-PCC practice. Always record media type term(s) and code(s).

Recording an identifier

Apply the option for objects. In addition to providing a structured description, follow the Final Recommendations of the Joint MLA/OLAC 33X/34X Task Group and record the source code "rdamedia" in $2, rather than the RDA Value Vocabularies: Media Type source code $2 rdamt.
