The OAI protocol facilitates the aggregation of large numbers of heterogeneous metadata records. In order to make harvested records useable in the context of an OAI service provider, the records typically must be filtered, analyzed and transformed. The CIC metadata portal harvests 450,000 records from 18 repositories at 9 U.S. Midwestern universities. The process implemented for transforming metadata records for this project supports multiple workflows and end-user interfaces. The design of the metadata transformation process required trade-offs between aggregation homogeneity and utility for purpose and pragmatic constraints such as feasibility, human resources, and processing time. 1 Aggregating Metadata Describing Scholarly Resources In recent years, large aggregations of metadata describing heterogeneous resources have been created using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). OAI service providers who build applications on top of such aggregations ...
