Metadata and Cross-Collection Searching in Luna’s Insight

Cornell Institute for Digital Collections

Problem: Integrating Access to Visual Collections

• Diverse visual resources and descriptions– Multiple repositories at Cornell, multiple digital

collections, distributed digital collections– Different discovery methods and metadata formats

• Searchers are on their own to be aware of collections, know how to link to them, and search different interfaces

1st Solution: A Shared Union Catalog for Images

• Adopted MultiMIMSY 2000 from Willoughby Associates– Museum collections management software– Moved data from stand-alone applications

into it– For the past 4 years, have worked on

developing shared standards and practices

Standards Issues

• No museum descriptive standard– CIDOC reference framework as a glue?

• We have tried to follow VRA 3.0

• Use AAT, ULAN, TGN, for data values

Cornell Institute for Digital Collections

Is VRA 3.0 too complex?

• [example]

2nd Integration Solution: Insight from Luna Imaging

• Addresses issues of collection diversity– Can search multiple collections at once

• Addresses issues of metadata diversity– Maps data to a common standard– Allow searching across multiple

heterogeneous collections

Insight Demo

• Selected features:– General search and display attributes– Cross-collection searching– Variable metadata displays– Annotation tool– Support for formats

Insight’s support of descriptive complexity

• Controlled vocabulary lists and repeating values for fields;

• Hierarchical structures and values; • Groups of fields that should be treated

together, e.g., artist name, life dates, nationality;

• Display order of values, fields, and groups of fields

“Built-in” Metadata Standards

• Dublin Core

• MARC

• VRA 2.0

• VRA 3.0

• CDWA

You can add whatever you like

Implementation: Data into Insight

• Currently, export desired data as Text files, clean it up, and import into Insight

• This year – link tables between the two systems?

Cornell Institute for Digital Collections

What is ahead for Insight?

• Development of stand-alone cataloging tool (May?)

• Further support for hierarchical objects– Books, letters

• Links to LDAP and Kerberos authentication

• GIS support
