Discussion Points1. Background2. Overview of prototype biographical resource and access system3. Future directions and open discussion

Context• Research and demonstration project• Sponsored by NEH• Grant term: March 2010 – March 2012• Three partner organizations: – Institute for Advanced Technology in the Humanities, University of Virginia – School of Information, UC Berkeley – California Digital Library

Goals• Develop tools for extracting EAC-CPF records, drawing on existing data (EAD finding aids/ collection guides)• Build a large test corpus of EAC-CPF records• Create a prototype biographical resource and access system, using those records

What is EAC-CPF?• Encoded Archival Context – Corporate Bodies, Persons, and Families• Standard for encoding archival authority records: – Authorized name headings for the entity – Biographical/historical context for the entity – Links to resources created by the entity, and about the entity • Collections (represented by EAD finding aids) • Bibliographic resources, etc.

EAD and EAC-CPF

A Vision for Integrated Access

A Vision for Integrated Access Freebase

Data Inputs• EAD Finding Aids – Online Archive of California [~14,000] – Northwest Digital Archives (NWDA) [~5,200] – Library of Congress [~900] – Virginia Heritage [~8,300]• Authority Records – Library of Congress: NACO/LCNAF [~4+ million] – Getty Vocabulary Program: Union List of Artist Names (ULAN) [~290,000] – OCLC Research: Virtual International Authority File (VIAF) [intersection with NACO/LCNAF]

Data Flow VIA F ULA N

Data Flow• Extract names from EAD finding aids – Creator names (<...name>) with biographical/organizational histories (<bioghist>) – Names as subjects (<controlaccess>) – Names in correspondence series• Normalize and convert into EAC-CPF; retain link back to EAD(s)• Match EAC-CPF records against one another and against existing authority records (ULAN, VIAF, LCNAF) – Enhance EAC-CPF by normalizing entries, adding alternative entries, titles, languages used, and sex (VIAF), and historical data (ULAN)

Meet the target users

Meet the target users Randy: Graduate student working on a PhD that involves biographies and the study of diplomatic families and networks. Sometimes he comes to the site looking for information on specific people; other times he is looking for information on a specific subject or event. He also TAs an undergraduate history class and sometimes has to help students find topics for papers.

Future Directions?• From research and demonstration to longer-term resource?• Integration of merged data back into EAD access systems?• Distributed cooperative archival authority control that is crowd-sourced by researchers and curated by archivists?• Scale up EAD data sources?• More links to external resources (Wikipedia, WorldCat Identities, openURLs)?• Social network visualizations/interactive navigation?• Unique identifiers for EAC-CPF records (ORCID, ISNI, ARK)?• Standardized name entries for source repositories contributing EAC-CPF records?
