As a refinement
of PBCore's element TYPE, TYPE.FORM is best used to aggregate resources
into categories related to the structure of the content
for the resource being decribed. There
is an implied hierarchy when using the elements TYPE, TYPE.FORM
and TYPE.GENRE.
TYPE is the manner in which content is presented,
viewed or heard by a user.
TYPE.FORM is the manner in which the content is structured for presentation.
TYPE.GENRE is the topical nature of the content.
Examples are the best way to present the differences:
- TYPE = Moving Image
TYPE.FORM = Documentary
TYPE.GENRE = Environment
- TYPE = Interactive Resource
TYPE.FORM = Tutorial
TYPE.GENRE = Oceanography
Multiple terms can and should be applied to fully
describe a media resource.
The recommended best practice is to select descriptors
for the elements TYPE, TYPE.FORM and TYPE.GENRE from controlled
vocabularies. There are many available to reference when assigning
metadata to a media resource. PBCore has combined descriptors
from several lists, including the Tribune Media Services, PBS,
the Library of Congress, the International Press Telecommunications
Council, Minnesota Public Radio, WGBH, and Media Solutions/University
of Utah.
