OCLC Online Computer Library Center, Inc. and Zepheira, LLC have announced that they reconstruct OCLC’s Persistent URL (PURL) service. The software developed will be released under an Open Source Software license allowing PURLs and the PURL infrastructure to be used in various applications for public or proprietary use. OCLC and Zepheira are collaborating to extend the community of PURL users. PURL has been designed to provide indirection that allows underlying Web addresses of resources to change over time without affecting systems that depend on them. Zepheira will redesign and build the new PURL service during 2007 intended to support new features and the scalability to face an increased demand for PURLs. The service will also be hosted by OCLC. The new PURL software update will be designed to reflect the current understanding of web architecture as defined by the World Wide Web Consortium (W3C). The software is designed to identify networked information resources, such as web documents, as well as non-networked resources such as people, organizations, concepts and scientific data.
