  6. 6. What is Metadata?• Data about data• Internally we outlaw the unqualified use of the word metadata• Three broad categories • Descriptive Metadata • Technical Metadata • Administrative Metadata
  7. 7. Descriptive Metadata• Describes the content or underlying asset• Bibliographic information• Title, author, journal, date, page, etc.• Used to create citations• Use to categorize or organize information• Creates the browse interface to content
  8. 8. Technical Metadata• Describes the structure or format of an item• Allows for verification or validation• Typically used for internal operations• A registry can be used to catalog these• Commonly needs to be migrated, although this applies to all metadata• Most suitable for automated processing
  9. 9. Administrative Metadata• Generally deals with how an item has been handled• Most relevant to the archival records• Tracks history of change or access• Closely related to workflow• Can be gathered automatically and unobtrusively
  10. 10. What is Journal Workflow?• The process of creating the finished product• Can be formal or ad-hoc• Automated or manual• Stress-relieving or stress-inducing
  11. 11. What is the relationship?• Metadata can be managed during the journal workflow process • Added, ingested, modified, calculated, stored, versioned• Metadata is used to drive the workflow process itself• The intended use must be considered carefully • Why are we gathering this? • Who is the audience? When? Why? • What about statistics, for example? • Connections into other business process systems
  12. 12. JSTOR Observations• Metadata is created for every word, illustration, page, article, issue, title• Authorizable units are described with metadata• Users are described with metadata• We have established internal guidelines and standards • Relationship to, but not the same as external exposure• Quality assurance and quality control are involved in oversight• Formalize workflows early when it is easier• Get it right up front, it is expensive to go back
