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

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
