Further development of the PURL software is shifting to 3 Round Stones. 3 Round Stones has taken over production PURL services previously offered by Talis Group Ltd's US subsidiary, Talis Inc. The community services for PURLs including the Web site and discussion list remain unaffected. 3 Round Stones intends to continue to develop the PURL software to include IPv6 support in the coming months.
NCBO and Zepheira announce development of a PURL Federation on 22 March 2010.
The National Center for Biomedical Ontology and Zepheira are pleased to announce work on a PURL Federation. A PURL Federation will allow multiple PURL service operators to cooperate in PURL resolutions, covering for each other in the case of service outages and allowing the persistent resolution of PURLs as funding levels and organizational details change with time.
PURL Federations are intended to enhance the ability of Semantic Web and Linked Data communities to ensure the persistence of their identifiers.
Prototypes of the PURL Federation code will be released occasionally in the coming months, with an Alpha version to be released in the Summer of 2010. Further announcements of releases will be made on the PURL Discussions group
and on http://purlz.org.
The architecture document guiding the development of a PURL Federation is available at:
Review and feedback on the proposed architecture is encouraged. We want to hear your use cases and good ideas. Thanks in advance.
