Working Group: Practical Policy Rainer Stotzka, Reagan Moore

2  Extend the concept of “Data in Context” to “Collection in Context”  A collection provides the context for understanding data  Provenance metadata  Descriptive metadata  Structural metadata  Workflows  Administrative metadata  However, each collection has a driving purpose that represents the consensus of a user community  We observe the the members of the user community evolve, implying re-purposing of the collection.  The evolution redefines the required metadata for the collection context Concept Extensions

3  Local project  Members have detailed tacit knowledge of the semantics, structure, description  Data grid  Data are shared with other institutions, requiring description and access controls  Digital Library  Data are published for the entire discipline, requiring provenance, description, structural information  Reference Collection  Data are published for use by future researchers, requiring knowledge of generation and management of the collection  Reproducible data-driven research  The workflows, input parameters and files, and output results from each execution of a workflow need to be saved  The policies and procedures used to manage an archive also need to be saved  Preservation is “communication with the future”  Preservation requires “validation of communication from the past” Example Collection Evolution

4  Identify the most important policies  Practical implementations for managing research data collections  Provide recommendations for a “starter kit”  Testbeds:  Evaluate standard policies  Test interoperability across WGs Policy: Assertion or assurance that is enforced about a collection or a dataset Practical Policy Working Group Focuses:

5 Policy-Based Data Environments  Purpose  Reason a collection is assembled  Properties  Attributes needed to ensure the purpose  Policies  Controls for enforcing desired properties,  mapped to computer actionable rules  Procedures  Functions that implement the policies  Mapped to computer executable workflows  Persistent state information  Results of applying the procedures  mapped to system metadata  Property verification  Validation that state information conforms to the desired purpose  mapped to periodically executed policies
