Designing a Metadata Management Repository
  • Michael Pelikan, Penn State University
  • Nathan Rupp, Cornell University
  • Jeff Young, OCLC

Many Digital Library Systems
3
A Couple of Metadata “Pieces”
  • Mapping
    • MARC not used in most digital library systems!
    • Various kinds of maps need to be developed:
      • MARCàDC
      • MARCàTEI
  • Transformations
    • Programming scripts that actually carry out the mapping
4
Metadata Management Design
  • Not just recording mapping & transformation processes
  • Also includes:
    • Decision processes that arrived at the mapping and transformation tools
    • Documentation of all this work
  • Metadata management design results in:
    • Promotion of sharing and reuse of tools
    • Recognition that librarians are users too
    • Improvement in operational activities
    • Reduction in the risk that metadata generation and transformation processes will be lost
5
A New Idea?
  • Importance of resource management in general:
    • Unlimited supplies of resources are expensive!
    • To maximize the value and minimize the cost of resources
    • To anticipate and meet the requirements of resources
    • To ensure that resources are used prudently, efficiently, effectively, and securely
  • Data resource management: data as important organizational asset
6
Benefits of Metadata Management
  • Cultural
    • Enhances communication
    • Involves many in furthering the library’s mission
    • Treats metadata as a shared resource
  • Functional
    • Enables easy location of metadata tools created throughout the library
    • Minimizes the creation of redundant components
    • Increases productivity among metadata and IT practitioners
    • Accelerates development of new metadata applications
    • Improves likelihood that new mappings and transformation tools will be easily integrated into the existing metadata environment.
7
Creating a MARC Metadata Management Design
  • Discussion and consensus
    • Costs
    • Benefits
    • Staff involved
  • Documentation and inventory
8
Metadata Inventory (1)
  • MARC bibliographic metadata
  • Script for extracting MARC metadata
  • Resulting file of MARC extract
  • Project specific MARC mapping
  • XML metadata collection and storage scheme
  • Script transforming MARC file to XML
  • Resulting file of MARC-XML transformation


9
Metadata Inventory (2)
  • Script integrating XML with administrative metadata and OCR into TEI
  • Resulting TEI file
  • DTD for validation
  • Metadata as it is stored in the DL system
10
Next Steps
  • Move from MARC repurposing design to metadata management design
  • Reusable transformation tools
  • Investigate the creation of a metadata management repository
  • Sharing metadata repositories
11
We keep thinking we’re the Jetsons…
12
The Big Idea(s)
  • It’s a Repository
  • = Discoverable Resources.
  • Discovered Tools are used.
  • Use = Practices.
  • Tools & Practices that are “in common” gain value as more folks use them.
13
Not just a bit bucket
  • Some kind of descriptive metadata
      • whether a centralized model or distributed, “standardized” description will make the tools discoverable.


  • If distributed, common descriptive practices can make it easy* to harvest / search the “catalog(s)”



  • *yes, easy.

15
But why stop there?
  • How about RUD?*


  • Why?
    • Folks could make informed choices among existing works closely fitting their needs.
    • Less duplication of effort!




    • *Real Usable Documentation
16
How about searchable comments?
  • “Well, we started with Cornell’s marc to DC but then added OCLC’s approach to mapping VRA because we had digitized photographs of statuary with…”


      • resolution for the images (dpi),
      • measurements in two-dimensions for the photos (inches),
      • and in three dimensions for the statues (centimeters, plus mass in kilograms)
17
Next thing you know,
  • Folks might start to use stylesheets from the same gene pool
  • After a few generations, there will come to be a “family resemblance” to these things…
  • Interoperability!
  • Best Practices!
18
So, even though we’ve already got standard methods…
  • We might start to see:
    •  Less re-invention, institution-by-institution.
    • Less wear & tear - creative solutions can be shared.
    • Easier interchangeability of parts (as a result of employing a rich, growing, but commonly-employed tools set)
      • Just like the Modern Age!
