Projects

Within this macro-project the following projects have been developed (please follow the links for further details):

• The Pantha Rei Schema Evolution Benchmark ^[1], a benchmark for schema evolution developed from the actual evolution of the MediaWiki DB backend.
• The History Metadata Manager ^[2], a tool to support temporal queries over metadata histories, and its Semantic Web Extension the Semantic HMM ^[3]
• The prototype system PRISM: tool for Graceful Schema Evolution ^[4], and its demo Prism demo page ^[5]

• The prototype system PRIMA: a system for querying Transaction-Time DB under evolving schema ^[6].

Funding

This work was supported in part by NSF-IIS award 0705345: “III-COR: Collaborative Research: Graceful Evolution and Historical Queries in Information Systems – A Unified Approach"
