In building the MyContacts tool in INDI, one of the primary goals of the design team was the ability to use the data it contains for authority control. Although there has been a long (and ongoing) debate over the importance of archival authority records, it appears from the recent formation of the Encoded Archival Context (EAC) Working Group that the archival community has decided to formalize the creation and sharing of these records. Yet as various writers have noted, archives face some difficulties in building EAC authority files, especially in attracting library participation in EAC databases.
For libraries, the primary concern of traditional authority control is headings management. By using a documented, authorized form of a person/corporate name in descriptive records, library systems are able to collocate materials and provide improved access to their materials. Many academic libraries are associated with the Name Authority Cooperative Program (NACO), and contribute authority records to the Library of Congress Name Authority File (LCNAF). Here at Brigham Young University we are also a NACO participant.
For many librarians, there is little to be gained from contributing to an archival authority file in addition to library authority file. Archives and special collections are oftentimes housed in the library in academic institutions, and contribute to the LCNAF as part of their MARC cataloging. In these circumstances, creating a second authority file would require unnecessary database management problems as they tried to keep both up-to-date. Additionally, some librarians do not see an advantage in recording the contextual information possible in EAC to authority records.
The recent publication of the Functional Requirements of Authority Data (FRAD) draft suggests that archival concerns about recording context are beginning to be addressed by the library community. While it is noted in the draft that EAC was not evaluated in the preparation of the document, the writers did consult the International Standard Archival Authority Record for Corporate Bodies, Persons and Families (ISAAR(CPF)), developed by the International Council on Archives and embodied in Describing Archives: a Content Standard.
In the FRAD model, names and persons are defined as separate entities. Names include various attributes, such as type, scope of usage, dates of usage, language, script, and transliteration scheme. Name records can then be associated with person records (or corporate bodies/families records), which contain information about the person, including dates, titles, gender, associated locations, languages, occupations, and biographical histories. Person records (or corporate bodies/families records) can also be associated with other entities to describe parent/child, hierarchical, or other relationships.

The resulting FRAD framework seems reminiscent of the EAC model, except that it separates the authorized form of the name (EAC identity element) as a separate record. This is also somewhat similar to the agency history records created as part of the RLG Government Records Project, which used LCNAF authorized forms for headings while keeping administrative history information in the bibliographic record. While FRAD is still in draft, it will be interesting to see what effect its conceptual model might have in the development of Encoded Archival Context.
In INDI we have already begun implementing the FRAD model by separating headings management (name record data) from contextual information (person/corporate name/family record data). The decision to do so was made primarily due to pragmatic considerations, but we believe will have long-term benefits for our program and should be considered by the wider archival community as we move toward the development of archival authority files. In INDI, the MyContacts record acts as the FRAD contextual record, containing information about the entity and associations with other entity records and with archival collections. For headings management, though, INDI relies on the LCNAF through record linking.

To accomplish this, MARC 21 Authorities records are currently synched with the Oracle database used by the library ILS system, and are searchable within INDI. Once the correct record is selected it is linked to the MyContacts record on the record number. While this setup requires close integration between INDI with the library ILS, it reduces the need for headings management to a single authority file. It is hoped that as the Library of Congress develops an Search/Retrieval via URL (SRU) interface for LCNAF similar to that currently used in their catalog that INDI will be able to do this searching and linking directly with the national authority file itself.
Then for EAC output, INDI will harvest the information from the linked LC authority record, using it in the identity section of the record. The MyContacts data in turn will form the contextual information for the description and relationship sections of the record. In future releases of EAC, perhaps this type of linking relationship could be integrated in the standard to prevent the duplication of record content between library and archival authority files.
We hope that by approaching authority control in this way we will be able to both honor our commitments to the NACO program and library community locally, while participating in the emerging archival authority control community. Attending presentations on EAC at the SAA conference in Chicago, it seems that many members of the archival community are ready to write off libraries as partners in archival authority file development, with the intent of building completely independent systems. Yet it seems foolhardy to ignore the infrastructure and detailed authority work already done by librarians. By using linked authority systems we may be able to leverage that system, integrating heading management and contextual data as recommended in the FRAD model.
