What is the OPEN ARCHIVES INITIATIVE
The goal of the initiative is to develop and promote interoperability standards that will facilitate efficient dissemination of digitally available content across various repositories - to make sure data within different repositories can be shared
What is OAI-PMH ?
Protocol for metadata harvesting (OAI-PMH): defines a protocol for harvesting metadata records from repositories that uses different systems; in other words, the protocol enables the sharing of metadata between services (think repository interoperability)
What is metradata Harvesting?
Harvest - the gathering together of metadata from a number of repositories into a combined data store
What open source elements does OAI-PMH use?
Uses Dublin Core (metadata format), HTTP ( to send request) and XML (to form response)
Why is OAI-PHM good?
Makes it possible to gather metadata from various sources into one database so that services can be provided based on this centrally harvested data
What is the difference between Data providers and service providers?
Data providers administer systems that support the OAI-PMH as a means of exposing metadata Example: National Library of Australia Digital Object Repository
What is DIGITAL OBJECT IDENTIFIER (DOI) SYSTEM
Designed for identifying content objects in the digital environment, DOI is a persistent identifier for a digitally published article along with its location
Who manages DIGITAL OBJECT IDENTIFIER (DOI) SYSTEM

What are the disadvantages OF OPEN SOURCE
May have a steeper learning curve
