Rapid Visual OAI Tool (RVOT) can be used to graphically construct a OAI-PMH repository from a collection of files. The records in the original collection can be in any one of the acceptable format. The format currently supported are RFC1807, Marc subset & COSATI formats. RVOT helps to define the mapping visually from a native format to oai_dc format, and once this is done the tool can respond to OAI-PMH requests. The tool is self-contained; it comes with a lightweight http server and OAI-PMH request handler and is written in Java. The design of RVOT is such that it can be easily extended to support other metadata formats.
