Description
A variety of examples have arisen in which the Open Archives Initiative Protocol for
Metadata Harvesting (OAI-PMH) has been used for applications beyond bibliographic
metadata interchange. One of these examples is the use of OAI-PMH to harvest
resources and not just metadata. Advanced resource discovery and preservations
capabilities are possible by combining complex object formats such as MPEG-21 DIDL,
METS and SCORM with the OAI-PMH.
In this tutorial, we review community conventions and practices that have provided
the impetus for resource harvesting. We show how the introduction of complex object
formats for the representation of resources leads to a robust, OAI-PMH-based
framework for resource harvesting. We detail how complex object formats fit in the
OAI-PMH data model, and how (compound) digital objects can be represented using a
complex object format for exposure by an OAI-PMH repository.
We also cover tools that are available for the implementation of an OAI-PMH-based
resource harvesting solution. Furthermore, we will provide examples of resource
harvesting projects that are based on the complex object format approach, including:
(*) The effort aimed at mirroring the collection of the American Physical Society at
the Research Library of the Los Alamos National Laboratory;
(*) mod_oai, an Apache module that provides OAI-PMH-based resource harvesting for
Apache Web servers;
(*) The DSpace MPEG-21 DIDL plug-in that allows harvesting of DSpace resources
through the native DSpace OAI-PMH interface.
