Digital Humanities Observatory

• Part of the Humanities Serving Irish Society (HSIS) consortium to develop an all-island inter-institutional research infrastructure for the humanities

• Defining, promoting and implementing best practices for…– Digitisation– Archival– Curation– Discovery– Presentation

• In particular, best practices for long-term data management– Fedora digital repository

Integrating Drupal and Fedora9/6/09 | Don Gourley| slide 3

Defining, promoting and implementing best practices

• Needs of HSIS partners vary widely• Projects focus on the immediate research

problem• Best practices also take a longer view of data

management• Predictive specifydesignbuild approach will

not work• Need an agile, adaptive approach

Demonstration repository

• Build an exemplar repository for storing, managing, discovering and delivering digital humanities resources

• Support demonstrator projects with specific services that each requires

• Provide a platform for experimenting and demonstrating new ways to link, analyse and visualise humanities data

• Identify useful repository services to generalise for other projects, and specify the metadata and content model profiles to which digital objects must conform in order to be used with the generalised services

Integrating Drupal and Fedora9/6/09 | Don Gourley| slide 5

Use case demonstrator approach

• Need rapid application development (RAD) tools

• Need flexible ways to access and display e-resources targeted at multiple skill levels

• Need to apply software engineering methods to ensure generality & re-use (e.g. abstraction, frameworks)

Drupal

• Content management “framework”• Thousands of contributed modules

provide content management functionality

• PHP low programmer-skill entry barrier

• Widely available hosting solutions

Islandora

• The original Drupal Fedora module• Lots of features:

– XSLT-driven collection views– API-A & API-M SOAP interface– Authentication using Drupal user / role tables– Policy definition & enforcement– Image manipulation– Virtual research environment

• Not a rapid application development environment• Not mapped to Drupal content data model

Next steps

• Implement API-M• Borrow Islandora authentication?• Link to GSearch?• More use cases!• More testing!• Collaborate with “solution communities”?
