    Abstract
    This paper proposes a model for metadata crosswalks that associates three pieces of information: the crosswalk, the source metadata standard, and the target metadata standard, each of which may have a machine-readable encoding and human-readable description. The crosswalks are encoded as METS records that are made available to a repository for processing by search engines, OAI harvesters, and custom-designed Web services. The METS object brings together all of the information required to access and interpret crosswalks and represents a significant improvement over previously available formats. But it raises questions about how best to describe these complex objects and exposes gaps that must eventually be filled in by the digital library community.

    Abstract
    The Open Archives Initiative's Protocol for Metadata Harvesting (OAI-PMH) was created to facilitate discovery of distributed resources. The OAI-PMH achieves this by providing a simple, yet powerful framework for metadata harvesting. Harvesters can incrementally gather records contained in OAI-PMH repositories and use them to create services covering the content of several repositories. The OAI-PMH has been widely accepted, and until recently, it has mainly been applied to make Dublin Core metadata about scholarly objects contained in distributed repositories searchable through a single user interface. This article describes innovative applications of the OAI-PMH that we have introduced in recent projects. In these projects, OAI-PMH concepts such as resource and metadata format have been interpreted in novel ways. The result of doing so illustrates the usefulness of the OAI-PMH beyond the typical resource discovery using Dublin Core metadata. Also, through the inclusion of XSL1 stylesheets in protocol responses, OAI-PMH repositories have been directly overlaid with an interface that allows users to navigate the contained metadata by means of a Web browser. In addition, through the introduction of PURL2 partial redirects, complex OAI-PMH protocol requests have been turned into simple URIs that can more easily be published and used in downstream applications.
