  1. NEESGrid Data and MetaDataTechnology Kincho Law, Jun Peng, Jim Eng, Terry Weymouth, Paul Hubbard, Charles Severance

  2. Outline • Model activities • Metadata tools and repository • Data as video • What is done • What we have to do

  3. Data Metadata The Slide There is a layer is where we develop tools which take advantage and begin to depend on of the “meaning” of the data – where we begin to depend on the meaning of a second. Where we make a viewer capable of viewing a certain type of object. This is where we build things which make use of knowledge. This layer will never be complete but it is a large focus of the coming months. Data Ingestors Search Data Mappers Concepts Data Viewers 09/2003

  4. How to prioritize model exploration and development • Focus on the following areas: • Areas where we have or are building tools • Areas where we already have incoming data in some format • Build the model through experiment based deployment - solve real problems in an open way and see if (with some adaptation) the solutions apply more broadly (i.e. Minnesota ) 11/2003

  5. Go Forward - Tools • Evaluate the ORST interface and use it to implement experiment-based interface to meta data repository • Investigate tools to represent structural data (like SAC data) • Extend and improve viewers – publish API so that sites can extend the viewers • Improve notebook • Single signon using CHEF/Grid credentials • Integration with Metadata • Smother integration with CHEF • Explore automated synchronized video and data capture and after-experiment replay of synchronized video and data (ORST UMinn) • Explore the capture of high quality still images as data (UMinn) • Investigate adopting a data-editing tool (XMLSpy) 09/2003

  6. RDF Integration • Some of the data and meta data task force members are using Protégé-2000 to develop their models and expressing them in RDF. • RDF and NEESML are very similar but not identical so it may be challenging to ingest any arbitrary RDF • We expect that we will be able to map a subset of RDF to NEESML for ingestion or adapt an RDF parser (Jena or Raptor) to ingest that subset directly into the repository 11/2003

  7. Data Model Activities • Groups have been formed to develop coordinated models • Shake Table • Centrifuge • Tsunami • GeoTech • Gokhan Pekhan is organizing this effort • Kincho / Jun / Jim pushed forward with a RDF-Based Shake Table Model from Protege-2000 and developed software

  10. Electronic Notebook • Collaborative effort with the DOE SciDAC • Electronic notebook - metadata entry • Data mapping • Data provenance • Data display • Slide data/metadata jakarta.apache.org/slide/ • Ultimate integration will be via JSR-170 • www.scidac.org/SAM/ • collaboratory.emsl.pnl.gov/docs/collab/sam/samtechoverview.html

  14. Data Turbine • Commercial, free data streaming toolkit

  15. Data Turbine (cont) • Existing data viewers will be adapted to access and display data from data turbine • Data acquisition software will be adapted to place information in Data Turbine Channels • Metadata elements will be developed to represent data turbine live, stored, and derived channels • New efforts (video as data) will be developed from the ground up using Data Turbine • outlet.creare.com/rbnb/ 11/2003

  16. Video as Data • Follow on to initial demonstration at ORST • Experiment based development: Minnesota • Design phase complete • Joint effort, NEESGrid SI, ORST, Minnesota, UC Davis, Texas, Buffalo, and others

  22. Tool List - To Do • Next release of repository • Integrate ELN into repository • DAQ Control Panel in CHEF • Set/Retrieve Metadata • Start / Stop • Ingest data from staging space • Data Turbine Control Panel in CHEF • Start / Stop / Configure Sources • Video | Audio | Data | Thumbnail • Control permanent storage of video

  23. To Do (cont) • NTCP Debugging and Monitoring in CHEF • Needed Data Turbine • Data as Video Client Tools in CHEF • New Monitor Tool • Still Image • Camera Control • Data Turbine Audio Capture • We may need to support XML Schema • QuickTime Capabilities • Archive, retrieve, slice, dice, convert, present • Probably will not be completed as part of SI effort

  24. Data Model Work • Data Curation Summit • Understand issues form go-forward plan • Meeting 3/18/2004 • Data and Metadata Task Force • Finish the tsunami and centrifuge models • DSAC Committee • Meeting 3/19/2004

  25. Summary • In September 2003, we met and “re-visioned” data • A bunch of requirements gathering and development has been done • The “high risk” elements are working now • There is more to do - We will run out of time • Evolutionary development approach - there will always be usable working code - we will stop when we run out of time

  26. The people… • Gokhan Peckan - Data Models • Kincho Law - Data Models / Software design • Jun Peng - Data Models / Software design • Jim Eng - Parse / Ingest / RDF / Project Browser • Jim Myers - Electronic Notebook • Terry Weymouth - Data Turbine • Paul Hubbard - DAQ and NTCP • Joe Futrelle - Data / Metadata Repository
