Draft 2: Identify existing schema(s) and a test corpus. (3%)
Revised General Domain/Topic:
The general domain/topic for our schema will be audio visual collections, especially moving image works, that cater to an academic audience. In particular we are interested in focusing on Home Movies. This hypothetical collection could be considered a special collection at a university used for scholarly research. An example of an archive similar to the one we envision would be the Walter J. Brown Media Archives and Peabody Awards Collection at the University of Georgia (https://bmac.libs.uga.edu/pawtucket2/index.php/FindingAids/Collections/key/8e901317e36cd5591162a1079efcc97a/facet/collection_area/id/1018/view/images) We are particularly interested in exploring the inclusion of user added metadata in our schema. Our group thought that combining elements of preexisting PREMIS and METS schemas with a more interactive approach would serve this type of AV collection well.

Justification for Schemas:
PREMIS is the international standard used to record the metadata which is used to support long term preservation and usability of an object. It was developed by the Library of Congress (LOC) and consists of a data dictionary and XML schema. It is mainly used for the recording of administrative metadata and is often integrated with METS. The PREMIS data dictionary combined with the flexibility of METS encoding standards is key to documentation of preservation metadata of AV objects. PREMIS root elements include object, event, agent and rights. PREMIS is a great metadata schema for the long term preservation of and use of digital AV objects. Because AV standards fluctuate frequently over time, PREMIS is a very thorough documentation system that ensures long term access to the object to a high degree.

METS is the schema used to record descriptive, administrative and structural metadata about objects in a digital library using XML. METS is also maintained by the Library of Congress as an initiative of the Digital Library Federation. Many times METS will specify the use of PREMIS as an extension schema. One of the main strengths of the METS schema is its hierarchical expression of digital library objects, including the names and locations of the files associated with the object and the corresponding metadata. In addition to facilitating the management and organization of digital library object metadata within repositories, METS also enables the exchange of this metadata. Exchanges may include those between institutional repositories, or those between institutions and their users.

PBCore is a cataloguing standard developed by the public broadcasting community and is specifically designed for the organization and description of audiovisual content. Built on the foundation of Dublin Core (ISO 15836), PBCore is specifically designed to address the needs of broadcasters, archivists, and academic. The detail offered by PBCore, lends itself well to user needs and will be well suited for adaptation to include user initiated metadata.
