Guaranteed Data Integrity in the GIG-NCES Environment

Our approach to the problem is to utilize IO metadata to convey provenance information. The JBI Metadata Repository then becomes the capturing system for provenance data. Reasoning capability becomes trivial following the capture of provenance data. Our pedigree system is modeled to allow for rapid formulaic reasoning. The trust management framework, coupled with the IMS Portal, provides the foundation for an Information Management System. Thru the IMS Portal the administrator may set trust levels of specific publishers to higher and lower levels. Publishers may be rewarded for providing reliable information and penalized when exceeding a level of unreliable publications. Hence publishers are discouraged from publishing inaccurate data which leads to the promotion of positive behavior in the JBI environment. Collaboration is implicitly supported by the trust framework. IO consumers will be able to utilize published data from unknown sources with the reliability that they require for their projects.
