  1. Measurement Data Workspace and Archive: Current State and Next Steps GEC15Oct 2012 Giridhar ManepalliCorporation for National Research Initiativeshttp://www.cnri.reston.va.us/

  2. Measurement Data Object • Measurement Data: • A sequence or stream of bytes that correspond to one or more I&M experiments • Could consist of • Planning data: scenario documents, source code, etc. • Input data: configurations, rspecs, etc. • Output data: log files, results, etc. • Captured as file-system directories and files for ease of use 10510.0.1/B5A7-D231-3929 • Measurement Data Object = Data + Metadata Exp. A & B • Data that corresponds to a ‘single’ experiment with one or more ‘runs’ Exp. A OR • Data that corresponds to ‘multiple’ related experiments Exp. B Metadata 10510.0.1/A2BE-C154-1874 PLUS • Metadata that describes the data object Experiment A Run 1 Logs Run 2 Logs Metadata

  3. Measurement Data Flow – Slices to Workspaces 2 2 Workspace 1 Workspace Slice Slice Key: 1. Experiment Initiated = Measurement Data Object 2. Measurement Data Collected 1 Experimenter X Experimenter Y

  5. Measurement Data Flow – Workspaces to Archive Registers Handle Handle System Stores Data . . . . . Archive Workspace N Workspace 1 Experimenter Experimenters

  6. Handle System Use Science Times Article Title Data ID Handle System 2 1 Archive User followsData ID into the Handle System. User is redirected to Data Objectstored in the Archive

  7. Extended Handle System Use Suite of extensible services end users can leverage by following the ID.

Archive User followsData ID into the Handle System. User is presented with various ArchiveService Options. User reaches the desired Archive Service.

  8. Next Steps • Consolidate I&M Metadata Schema • Simplify metadata for lowering the entry barrier • Define a serialization schema, e.g., XSD • Integrate the Handle System into GENI I&M Archive • Identify and define the Archive sustainability plan and usage policies • Who manages it? Who uses it? How to use it? Etc.
