Metadata Management and Connectivity

• XC OAI Toolkit– Make metadata available from a repository or ILS that does not

already have a standard interface– Once added, any OAI-PMH harvester can maintain a

synchronized copy of data in that repository• XC NCIP Toolkit

– Access to local authentication system (ILS, LDAP)– Access to circulation system in an ILS for status and placing

requests• XC Metadata Services Toolkit

– Metadata management tools– Pluggable services including aggregation, FRBR-ization and

record cleanup

XC OAI Toolkit

• Moves metadata with OAI-PMH– OAI Toolkit + ILS– OAI Toolkit + repository– OAI-PMH works with any metadata schema– Performance

• All XC components can talk OAI-PMH

XC NCIP Toolkit

• Integrates circulation with NCIP – NCIP Toolkit + ILS– XC discovery interface uses NCIP– Live circulation status– Authentication– Places circulation requests (hold, recall, etc)

XC OAI Toolkit


• Enables libraries to aggregate metadata and run services on it

• User interface for library staff, not end users• NOT a metadata editor (but can eventually

incorporate one)• Services– Automated– Configurable– Pluggable

10

How the XC MST works• OAI-PMH Harvester– Register remote OAI-PMH repositories to pull

metadata from, select subsets– Schedule harvests to pull incremental changes

• Local storage– Stores harvested metadata in any XML format– Stores results of processing by services

• OAI-PMH providers (repositories)– Makes all locally stored metadata available to other

harvesters– Make improved metadata available

11

How the XC MST works• Services

– Downloadable, plug-in services that process metadata and make new versions of the metadata

– XC provides some services, or build your own• Orchestration

– Select metadata for processing and sequence it through services• Faceted browse interface

– Library staff can browse harvested and processed metadata– Works with any XML schema

• Logs– Debug issues with harvested or processed metadata

12

XC advantages for metadata

• Enables automated handling of metadata changes:– New records, updates, deletes– Propagates changes throughout the system

• Web interfaces for trouble-shooting• Low risk of data corruption (easy to fix)• Ideal platform for experimentation

13

New roles for catalogers

• Design and test metadata services• Manage flow of metadata • System/application design• User research

14

XC metadata services

• Normalization– Transform metadata so that it can be displayed

• Schema transformation: – MARCXML to XC, DC to XC

• “FRBRization”• Authority control matching• Aggregation

15

Normalization Services

• MARCXML, Dublin Core• Stays in same schema• Prepares metadata for use in web applications

(faceted browse interface) or back into an ILS• Examples of normalized coded data:– Location codes– Languages– Type of material

16

Transformation Services

• MARCXML to XC Schema; DC to XC Schema• Parses data into FRBR Group 1 entity structure

(work, expression, manifestation, item, plus holdings)

• Creates additional works and expressions for MARC analytics (7XX fields)

17

Authority Control Services

• MARCXML, Dublin Core• Match headings against MARCXML authority

resource file• Populate records with authority control

identifier• Tool for debugging probable, unlikely matches• Prototype developed by RIT students

18

Aggregation Service

• Prepares metadata for use in XC user interfaces (Drupal and LMS Toolkits)

• Aggregates records that represent the same resource

• Manages relationships between records• Will give us experience managing FRBRized

records
