Implementing Z39.87

• General Policy Decisions
• Does every project necessitate implementation?
• Which elements are appropriate for a given
  collection (most are optional)? How much needs
  to be captured?
• Challenges
• New to the schema
• Vocabulary--what does YCbCrSubsampling mean,
  anyway?
• Fitting into overall workflow

• Classics Department
  Kevin Clinton
• Migrating an image collection of ancient Greek
  inscriptions from the Sanctuary of the Mysteries
  of Eleusis
• 900 images to a Luna Collection.
• Collection level metadata created using NISO MIX
  schema
• Three different types of images
• Kodak CD
• Scanned In-house
• Publication CD

Workflow

• Start with sample MIX document
• Pull Jhove records (image level data)
• Eliminate variable information (for collection
  level records)
• Annotate records (capturing information
  eliminating any unnecessary fields)
• Create xml files for each image type
• Import xml into METS document

Challenges of Clinton Collection

• Working with three different image types added
  complexity to the process- more information to
  gather and track
• Issues associated with Migrated Image type
• Unaware of original scanning set-up
• Limitations to change history field- difficult
  to fully capture conversion method within this
  schema
