Overview
OAI-PMH(OAI-Protocol for Metadata Harvesting) provides an efficient exchange of Metadata in its own standardized OAI format so called OAI protocol. The data are provided by the internal databases (data providers). The collected records are then processed by service providers and provided for search queries. The OAI harvester is working with simple HTTP GET requests and HTTP POST. The HTTP response provides the record data from the data providers in various formats.
TIB offers a search option to their data via OAI interface.
Each user is qualified to retrieve open access documents via OAI interface from TIB. The fee-basedmetadata are only accessible to authorized users. The above mentioned metadata are made availableby the OAI interface. The metadata is provided by different content and formal criteria so-called “Sets”. These Sets can be delivered by previous mentioned procedure using internal datbase collections. The Sets are divided into two different request methods so called “static Sets” and “dynamic Sets”.
Standards of OAI interface
We offer OAI protocol OAI-PMH Version 2.0. This protocol is based on well-known and popular standards.
This documentation will only give you an basic overview of the protocol. Please consult the standard for more information.
