is fundamental to information architecture. Furthermore, networks afford new models
for exchanging metadata. However, metadata exchange over the Internet remains
an ad-hoc, messy, and informal affair. There are several initiatives to develop
formal protocols for exchanging metadata over the Internet. The Semantic Web is
the most high profile and ambitious, but the furthest from implementation. RSS
is arguably the most common, though it is rarely described as a protocol for metadata
exchange. A promising newcomer to this field is the Open Archives Initiative Protocol
for Metadata Harvesting, or OAI-PMH. The OAI-PMH aims to be a simple, low-barrier
to entry, XML based protocol for the formal exchange of metadata records over
the Internet. The protocol seems poised to have a major impact. The specification
has stabilized, several toolkits are available, and it has been implemented in
several successful projects.
In this paper I will describe the OAI-PMH.
I will present goals and architecture of the protocol. I will explain how it works,
what it does, and what it does not do. Projects based on the protocol will be
demonstrated. There will be a brief survey of existing toolkits. I will also discuss
how the protocol can be used to support more robust information architecture solutions.
