Preparing for the Next Generation of Resource Discovery Tools using eXtensible Catalog Software

What is the eXtensible Catalog (XC)?Why should you care about XC?Overview of XC SoftwareHow XC contributes to improved metadataStatus of XC Development

XC Software Overview

eXtensible Catalog is open source, user-centered, next generation software for libraries.

Four XC software components: used together, provide an end-to-end

discovery system to connect library users with resources

Or can be used independently or in combinations to address a particular need.

XC - Worldwide

Library discovery systems

outdatedNew discovery systems don’t really meet libraries and users needs

Metadata only works in library

systems

Library users turn to Google

insteadLibraries in

danger of being marginalized

Libraries look for other

technological solutions

Libraries look to replace discovery

system

Breaking Through the Clouds

Legacy MARC metadata is holding us back

Making major changes to library metadata and systems is expensive

Metadata experts disagree about how to/whether to make changes

9

Regarding Metadata…

How do we even get started?

XC Software: A Place to Start

Choices for libraries concerning technology Opportunities to make the best possible use of

library metadata An architecture for moving and managing

metadata A low-risk way to try new things while also

maintaining the status quo

Metadata ToolsAutomated processing of large batches of metadata

Connectivity ToolsBetween XC and an ILSHarvest and synchronize metadata with OAI-PMHCirculation and authentication with NCIP

Features:

New type of staff client for processing large batches of metadata through a set of services.

Harvest from multiple repositories to address format and quality issues.

Automatic synchronization propagates changes through services and on to discovery interface.

Services clean up/normalize inconsistent metadata

Aggregate metadata from multiple repositoriesConverts MARC/Dublin Core metadata into XC

Schema metadata for use in XC User InterfaceMST is not a metadata editor (but can eventually

incorporate one)

Metadata Services Toolkit Tasks

–Add Repositories–Schedule Harvests–Add Metadata Services–Add Processing Rules–Browse Records–View Logs–Set up Users/Groups

Get metadata

Verify results/ Troubleshooting

Tell MST what to do with metadata

Admin functions

XC Metadata Services

Normalization – clean up MARCXML Dublin Core

Transformation – one schema to another Aggregation – combine multiple repositoriesAuthority Control (planned) – validation

XC Metadata Opportunities

MST = Infrastructure for “FRBRization”RDA in a non-MARC Environment

XC Schema combines elements from various other schemas, including RDA

Semantic Web/Linked DataURIs for all elements in XC Schema

MARC to XC Schema Transformation

XC Work

XC Expression

XC Manifestation

XC Holdings

MARC Bibliographic

MARC Holdings

•Includes some RDA data elements•All data elements have URIs

20

Metadata Opportunities

What if we’ve gotten this ALL WRONG?

21

XC Enables Experimentation

Harvests a copy of metadata from an ILS or repository

Very low risk of data corruptionXC propagates changes throughout the systemWeb interfaces for trouble-shooting“Sandbox” for experimentation
