Fedora 4 as a Shared Linked DataRepository for the AIC Collections

Stefano Cossu, Director of Application Services – The Art Institute of Chicago – scossu@artic.edu Open Repositories Conference 2014, Helsinki, Finland

The AIC Collections

l  250,000 art objects in Collections l  Several millions of image and text assets l  Many different departments access these data

l  11 Curatorial depts. l  Registrar l  Conservation l  Imaging l  Publications l  Help Desk l  Etc.

Goals

l  Build a scalable asset repository l  Create a pool of shared, linked information l  Move toward a de-centralized, asynchronous

architecture l  Maintain current CMS as the main management

platform l  Standardize data formats

Why Fedora?

l  Scalable and reliable l  Interface agnostic l  Content agnostic l  Modular, distributed l  Community driven

Fedora 4: a hard decision

l  We built a F3 proof of concept, then moved to F4 l  F4 features are very helpful to our mission l  F3 had the guarantee of stability l  Some features won't be available soon in F4 l  Starting with F3 and migrating to F4 later would have

been very time-consuming

Fedora 4 Key Features for AIC

l  Federation of external sources l  Asynchronous content processing (Sequencers) l  Powerful REST API l  Clustering l  Completely RDF-based l  Based on a reliable storage engine (Modeshape)

Use case proposals

Functionality we plan to build around F4 features: l  Building a pool (or better, a LAKE) of shared data l  Large file ingestion l  Content modeling

Use case 1: LAKE – Linked Assetand Knowledge Ecosystem

LAKE Gateways to Shared Data

AIC Departments with Access Roles

Non-Shared Data

Federate WWW Resources

Use Case 2: Ingesting Large FilesUsers upload assets to remote FS

Manifest file triggers ingestion

Derivative generation and metadata

Use Case 3: Content Modeling

RDF relationships
