Metadata Evaluation and Improvement

For many years metadata development activities have focused on developing and sharing metadata for discovering data. This is important. Once data are discovered, metadata supporting use and understanding become important. Efforts to encourage scientists and data providers to create those metadata have had limited success. This talk describes some approaches and tools for supporting the organizational change efforts required to integrate use and understanding metadata into organizational cultures. These approaches are described in terms of the ideas presented in Switch: How to Change Things When Change is Hard.

  • The simplified destination is documentation for discovery, use, and understanding
  • The feeling we are aiming for is the satisfaction of creating trustworthy data. Everyone that collects data wants the data and the processing of it to be trusted.
  • We are already 1/3 of the way there.
  • Identification is the keystone of discovery and it has a lot of elements. We are actually more than 1/3 of the way there.
  • A complete picture of where we are headed broken up into do-able steps.
  • The rubric web application has information about how to accomplish the spirals and links to a community resource (wiki and other web pages) for more information.
  • This Figure summarizes rubric scores for 52 records from the Alaska Satellite Facility (ASF). The x axis shows the spirals used to calculate the score. The y-axis shows the differences between the scores and the global average computed fro over 2400 EOS metadata records. Two groups were identified and they had the same scores for all but one spiral (that is why only the red line shows up. In the description spiral the scores were different. Fourteen of the 52 records had above average scores (bright spots) and 38 had below average scores (opportunities for improvement). The bright lights serve as good examples for the community.
  • the same analysis can be done for other groups of records within the EOS community. Each has local and global bright spots and opportunities for improvement.
