  1. EML Congruency Checker A tool to assess and report on the quality of EML-based data packages

  2. Software Stack ECC LTER NIS Data Manager Web-service Data Manager Library (Java Library) (Quality Checks & Reports) PostgreSQL

  3. A Brief History Data Manager Library (2006) Costa, Jones, Leinfelder, Servilla, and Tao LTER All Scientist Meeting (2009) eml-dev, NCEAS Econinformatics group, LTER Developers, LTER Information managers Data Manager Web-service (2011) Costa, Earl, Gastil, O’Brien, Ramsey, Servilla, and Stephenson EML Congruency Checker (2011) Gastil and O’Brien

  4. Checks must be defined case-by-case First: Structural Second: Scientific Error-free Metadata-data congruence Error-free data PASTA ready ? Complete Metadata

  5. ECC v0.1 Error-free Metadata-data congruence Error-free data ECC V0.1 IMC Annual Meeting 2011, EIMC

  6. Collected Quality Checks google_doc_quality_checks google_doc_quality_checks

  7. EML Congruency Checker Version 0.1 Checks: • Data URL is valid • Display data from the URL • Database table can be generated • Data can be loaded into the database table • Compare number of rows loaded to number specified in metadata IMC Annual Meeting 2011, EIMC

  8. ECC v0.1 – Current Capability Quality Check Field:  System     KNB: any package        LTER: apply only to LTER Type:     Data      Metadata  Congruence  Status:     Valid, Info, Warn, Error IMC Annual Meeting 2011, EIMC

  10. Future Direction • Implement full suite of quality checks • Work form current list (Google spreadsheet) • Design/specify Metadata Quality Checks with LTER Network Information System developers and Tiger Team • Improve community customization • Separate quality check configuration from processing logic where possible • Engage community through collaborative effort

  11. production oriented workshop: Criteria for “pasta-ready” Involve Pilot sites Use pasta calendar Synthesis data project calendar PASTA = provenance automatic synthesis tracking system
