Mets2011 dlf lightning ppt

  1. 1. Metadata Encoding and Transmission <ul><li>Brian Tingle -- Lightning talk </li></ul>
  2. 2. Use Case <ul><li>I work on access systems </li></ul><ul><li>content from multiple campuses / departments </li></ul><ul><li>It makes sense to me that different projects/domains may need different descriptive metadata </li></ul><ul><li>Why does structure and file USE vocabulary need to be different? </li></ul>
  3. 3. METS is hard <ul><li>[popular system] Developer “I looked at METS for a couple of days and couldn’t figure it out” </li></ul><ul><li>with a couple of notable exceptions, METS has not been widely adopted, represents a high bar for submission to CDL </li></ul><ul><li>Merritt repository is model free; low bar for deposit, but strong desire for access layers on top of it </li></ul>
  4. 4. My METS 2.0 vision <ul><li>low bar; should be easy to do by hand if needed </li></ul><ul><li>few choices; there should be one clear way to model something </li></ul><ul><li>support pluggable access layers / repository interoperability </li></ul><ul><li>leverage other standards and extant technology where possible </li></ul>
  5. 6. should we be developing a constellation of related standards, rather than one monolithic schema?
  6. 7. A way forward? <ul><li>simplified object model (theory of digital objects and description) that is divorced from serialization technology </li></ul><ul><li>standardize “USE” vocabulary/relationships for common digital library community use cases </li></ul><ul><li>incrementally add more complexity based on actual use as optional extensions </li></ul>
  7. 8. Abstract Descriptive Unit (div) metadata describedBy set of binary digits (files) Abstract Descriptive Unit
  8. 9. <ul><li>some related experiments are here: http://json4lib.readthedocs.org / </li></ul><ul><ul><li>javascript API for object access </li></ul></ul><ul><ul><li>“objset”s can be physically nested in the JSON serialization, or included by JSON referencing </li></ul></ul><ul><ul><li>used in production for new Calisphere slideshow widget </li></ul></ul>
