Phase II Goal: Facilitate reproducible science
. Track data derivation history . Track data inputs and outputs of analyses . Track analysis and model executions . Preserve and document software
. Link all of these to publications New Tools . Provenance indexing and search . Web user interface for browsing provenance . Matlab tool for generating provenance . {R tool for generating provenance} Semantics: enabling improved discovery
Goal: Improve precision and recall of search . Annotating data with semantic types . Extending search systems to incorporate semantics . Display / edit semantic annotations in the web UI New first-class objects in DataONE . Annotating data with semantic types . Semantic Annotations New Tools . New model for linking semantics to data . New KR models for Carbon Cycle and related areas . Ontology repository . Automated classifier to assign semantics to variables . Web UI for browsing and editing semantics Collaborations Challenges
