Accession metadata set

Definition of elements:

Institution:
The institution element records the name of the agency that is sending the object.

Representation Information:
Gives meaning to the bitstream. Records the digital class of the record, or, filetype. Also records the size of the file in bytes, megabytes, or gigabytes so that the repository knows storage requirements for the object.

Accession Instance:
Records information about the occassion of accession itself, including date, time, primary actors, and accession number.

Transactions:
Describes any monetary or legal exchanges that take place during the occasion of accession, such as transfer of title, purchase of the incoming object, contracts that are established, licensing agreements, or custody agreements.

Authentication:
Authentication checks the authenticity of the object. The authentication indicator is the authentication mechanism that was used.

Validation:
Describes if the logical structure of the transferred object is valid. The validation indicator is the mechanism used to check for validity. An example of this would be a message digest.

Archival Bond:
The archival bond element relates the incoming object to objects that are already archived in the repository. The Category sub-element describes the relation of one item to another, such as topic or creating agency. The categories used to describe the object belong to the repository. There is no limit on the number of categories that can be listed for one object.

Unique Identification:
Any unique entity that points to the object.

Security:
Records the mechanism(s) used to check the object for viruses.

1.   The Institution element is used by the University of North Texas in the metadata set they created for the Portal to Texas History.  However, they use this element to serve digital rights management purposes.  In the context of accession, I have used this element  to provide  basic provenance information.           

2.  Both CEDARS and the OAIS Reference Model use the term Representation Information to describe the digital class of an item. 

3. This element for recording authenticity is taken from CEDARS.

4. InterPARES developed this term for the relationship(s) that link the item to other items in the repository.
