Open Access Initiatives:-
Open access scientific outputs are scattered across many disciplinary archives, institutional e-print archives, institutional repositories and open access journals. There-for, it is difficult for scholars to locate all needed works on a particular subject.

OAI is one of the international movements to solve this problem. It aims to develop and promote the use of a standard protocol, known as Open Archive Metadata Harvesting Protocol. It is designed for better sharing and retrieval of e-prints residing in distributed archives. It also promotes the interoperability standard that aims to facilitate the efficient dissemination of the content.
OAI is an attempt to build a “low barrier interoperability frame work” for archives containing digital contents. It allows people to harvest metadata from data providers.

Mission of OAI:-
The mission of OAI is to develop and promote interoperability standard that aim to facilitate the efficient dissemination of the content. The protocol for metadata harvesting, a tool developed through OAI, facilitate interoperability between disparate and diverse collections of metadata through a relatively simple protocol based on common standard such as XML, HTTP and Doublincore.

The open archive world is divided in to data providers or repositories and service providers.

Data provider: A data provider maintains one or more repositories (web servers) that support the OAI-PMH as a means of exposing metadata. These are repositories which process the request and and respond to service providers with appropriate OAI-PMH responses. They are the creators and keepers of metadata for repositories and archives of resources.

Service provider: A service provider issues a OAI-PMH request to data providers and uses metadata as a basis for building value added services. They are harvesters of metadata for the purpose of providing a service such as a search interface, peer-review system etc.
