The NSDL was built three years ago using Dublin Core and OAI‑PMH metadata aggregation, with the expectation that these low‑barrier standards would be easy to automate and administer. The paper reports on the experience and evaluates the cost, functionality, and effectiveness of the metadata‑aggregation architecture. The experience shows that the low‑barrier standards enabled rapid deployment but proved harder to automate and more costly than expected, contradicting initial assumptions.
Over three years ago, the Core Integration team of the National Science Digital Library (NSDL) implemented a digital library based on metadata aggregation using Dublin Core and OAI-PMH. The initial expectation was that such low-barrier technologies would be relatively easy to automate and administer. While this architectural choice permitted rapid deployment of a production NSDL, our three years of experience have contradicted our original expectations of easy automation and low people cost. We have learned that alleged "low-barrier" standards are often harder to deploy than expected. In this paper we report on this experience and comment on the general cost, the functionality, and the ultimate effectiveness of this architecture.
