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

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
