  1. Describing Resource in a Digital Library: What Metadata can do for You Katy Ginger – DLESE Program Center Melissa Dawe – University of Colorado Karon Kelly – DLESE Program Center Dave Mogk – Montana State University Metadata Focus Group Website: http://www.dlese.org/Metadata/conference/index.htm

  2. Focus Group Agenda • Metadata focus group goals (5 mins) • Metadata and searching (15 mins) • Hands-on metadata (40 mins) • Hands-on metadata reflection (15 mins) • Metadata realities (5 mins) • Needed community support (10 mins)

  3. Participant Goals Understand the power, challenges, and cost of metadata creation Inform DLESE of innovative search paths Improve DLESE search-ability by contributing to the metadata effort Facilitator Goals Understand community search behaviors that lead to resource discovery Recruit contributors to catalog, create vocabularies & identify resources Metadata Focus Group Goals

  4. Metadata & Resource Discovery QUESTION: Using the Web, how do you find materials for your classroom, educational setting, or for a library user?

  5. Initial Community Responses • Trusted web sites or known authors • One or two keywords in a search engine • Refine keyword searches • Follow interesting web search paths • Information from colleagues • Workshops • Ask students or librarians to find materials

  6. Metadata & Resource Discovery QUESTION: What do you want to know about a resource?

  7. Power of Metadata – User Scenario You are a K-12 educator who has been asked to teach an introductory weather course. You have never done this before. You want resources that are classroom tested for laboratory use and lecture materials at the high school level. You want hints on their educational use. It is also important the material meet science standards and work on a PC.

  8. Search Criteria from Scenario • Weather • Grade level • Science standards • Lab exercise or lecture material • Classroom tested • PC-compatible

  9. Initial Community Response • Title, author, publisher • Time and geographic coverage • Hardware/software requirements • Age, learning time required • Subject (description and keywords) • Date, version • Resource type, URL

  10. More Community Response • Is it classroom tested or peer reviewed? • Is there information on the material’s use? • What National Science Standards are met? • What grade level is the material for?

  11. What is Metadata • At a library how do you search for a book? • Author • Title • Subject heading • Date • Metadata: Information about a resource that enables resource discovery

  12. Hands-on Metadata • Catalog Remote Sensing Using Satellites (pairs) http://www.comet.ucar.edu/nsflab • Go to: DLESE Prototype Metadata Entry Formhttp://melissa.page.ucar.edu:8080/BOZEMAN/

  13. Hands-on Metadata Reflection • What was easy or frustrating? • Would you find it easier to enter metadata if you were the author of the resource? • What would you add or delete? • What ideas do you have to make metadata creation easier? Let’s look at your created records.

  14. Extended Metadata Record • Includes community search ideas mentioned previously http://www.dlese.org/Metadata/conference/example.htm

  15. Metadata Realities • It was challenging to create metadata! • For 50,000 resources, it would take 1 cataloger 17 years to add them to the library if he/she spent 1 hour with each resource • In the process of making a resource digitally available, 2/3 of the cost is creating metadata • So metadata needs to be community provided

  16. Needed Community Support: 5 Tasks • Vocabulary development and review • Identify resources for the DLESE collection • Interpret metadata fields (e.g. coverage, learning style) • Take search paths and develop them into searchable classification schemes • Cataloging
