Balisage Paper: REST for document resource nodes: IPSA RE for the arcs
Walter E. Perry
Walter Perry, PhD. is Managing Director of Fiduciary Automation in New York, where he has 27 years experience building distributed systems for processing transnational financial transactions, their settlements, and associated regulatory and accounting compliance and reporting. He has spoken widely over the past dozen years on XML-defined transaction processing, XML database issues, and the elaboration of semantics from XML syntax. He was the founder and leader of the XML Special Interest Group of New York.
The IPSA RE (Identity, Provenance, Structure, Aptitude, Revision, and Events) architecture describes and processes the linkages that relate document resources within a network or graph of nodes. The architecture can be formalized by manipulation of document resource nodes by each of the four fundamental RESTful verbs. The system under development handles identity authentication by realizing identity as a chain of provenance or as a unique structure of context rather than relying on any internal attributes of a node to establish either that node’s identity or the identity of any entity for which that node is a proxy.
