Using MARC Repurposing to Initiate a Metadata Management Design
Marty KurthALA Annual ConferenceJune 27, 2005
This presentation is based on:Martin Kurth, David Ruddy, and
Nathan Rupp. "Repurposing MARC Metadata: Using Digital Project Experience to Develop a Metadata Management Design." Library Hi Tech 22:2 (2004): 153-165.
MARC repurposing is the reuse of MARC metadata in library applications other than the catalog.
These Cornell digital collections use repurposed MARC metadata . . .
Metadata processing involves
Mapping - defining relationships between metadata schemes
Transformation - moving metadata between schemes
Metadata management - coordinating metadata tasks and resources
Metadata management challenges
Workflows are not well established
Mapping and transformation work is decentralized
Documents and files reside throughout the library
Why manage MARC repurposing?
We have lots of MARC metadata
It always involves mapping and transformation
MARC mapping and transformation processes and tools are expensive
It involves redundant data, which is messy and expensive to maintain if you’re not careful
Managing mapping

XML/XSLT transformation
Because mappings vary from collection to collection, transformation scripts vary, too!
MARC transformation approaches
Scripted transformation processesIT staff extract selected MARC fields and encode them in XML
XML/XSLT transformation processes IT staff extract entire MARC record and
convert it to MARCXML Metadata staff use XSLT to transform
MARCXML to collection-specific scheme
Why we like the XML/XSLT approach
To keep catalog extracts constant
To put transformation tools in the hands of the staff doing the mapping
To facilitate tweak-and-test transformations
Documenting decentralized transformations is critical.
Developing a metadata management design
Two aspects of metadata management
Coordinating metadata creation and manipulation work
Managing tools and files resulting from metadata processes
Keys to managing metadata resources
Approach metadata processes as a coordinated, purposeful venture
Identify the needs of internal users to access and reuse metadata tools and files
Treat metadata tools and files as data resources warranting management
Develop a metadata management design
Metadata management design strategies
Inventory metadata relationships and processes organization-wide
Identify data stewards for mapping and transformation resources
Promote sharing and reuse of metadata resources to reduce costs and risk
Use documented relationships and processes to coordinate metadata activities
MARC repurposing inventory example

Collection-specific MARC mapping

XML delivery DTD
XML storage-to-delivery transformation script

Next steps
Continue to build library consensus about metadata element sets and mappings
Develop reusable transformation tools
Meet with stakeholders to discuss creating a MARC repurposing design
Extend stakeholder discussions to a library-wide metadata management design
Investigate creating a repository of metadata schemes, tools, and files
