OSU is solving this problem with an institutionally scoped, low maintenance SKOS/FOAF "name authority file". People in the IR are assigned URIs, names are maintained as skos:prefLabel, altLabel, or hiddenLabel. We've developed a simple Python application allowing staff to update individual "records", and code on the DSpace side to access the dataset over SPARQL. This presentation will walk you through where we are now, limitations we've run into, and possibilities for the future.
== Meta-Harvesting: Harvesting the Harvesters ==

The emerging Digital Public Library of America (http://dp.la/) has proposed to aggregate digital content for search and discovery from several regional "service hubs" that will provide metadata via an as-yet-unspecified harvest process. As these service hubs are already harvesters of digital content from myriad sources themselves, the potential for "telephone game"-esque data loss and/or transmutation is a significant danger.
This talk will discuss the experience of Digital Commonwealth (http://www.digitalcommonwealth.org/), a statewide digital repository currently in the process of being revamped, refactored, and redesigned by the Boston Public Library using the Hydra Framework. The repository, which aggregates data from over 20 institutions (some of which are themselves aggregators), is also undergoing a massive metadata cleanup effort as records are prepared to be ingested into the DPLA as one of the regional service hubs. Topics will include automated and manual processes for data crosswalking and cleanup, advanced OAI-PMH chops, and the implications of the (at this time still-emerging) metadata standards and APIs being created by the DPLA.
Every crosswalk, transformation, migration, harvest, or export/ingest of metadata requires informed decision making and precise attention to detail. This talk will provide insight into key decision points and potential quagmires, as well as a discussion of the challenges of dealing with heterogeneous data from a wide variety of institutions.
