Abstract
Aside from the basic importance of metadata in documenting, the characteristics of data for reuse is the fundamental role it plays in the functioning of digital libraries and data repositories. Metadata provides both the content of the search catalogs and provides part of the basis for performing quality control on the source data. In this paper, we describe a method for a scalable and decentralized system of interoperable digital libraries and data repositories. The description includes transportable metadata format, a persistent naming convention for arbitrary digital objects and a protocol for the asynchronous distribution of metadata. We also include a description of an operational data repository based on these methods.
