EXPO: A Modern NoSQL-based ebXML Registry for Health Information Systems

In this paper, an extension of a MultiModel NoSQL database is proposed in order to transform it on an ebXML registry, a complete system for Business-to-Business (B2B) information exchange. It can be used as key component of the interoperability infrastructure developed within the OpenInFSE project. OrientDB has been chosen as MultiModel NoSQL database, having the characteristic of a graph database also including the document layer. Moreover, EXPO, an EbXml Plugin for OrientDB, is proposed as native extension for the OrientDB Server.
