1. HUB AND SPOKE TOOL SUITE PREMIS Implementation Fair – 7 October 2009 Bill Ingram Visiting Research Programmer University of Illinois at Urbana-Champaign

2. Background on Hub & Spoke  NDIIPP funded  Began as repository evaluation – DSpace, Fedora, EPrints, and Greenstone – against an OAIS-based checklist.  The need arose to build a software test bed to evaluate multiple repository systems with common test data.  Hub & Spoke tool suite was a natural outcome of the work that went into developing the test bed for repository evaluation. 2

3. Digital Repository Interoperability 3

4. METS-based profile, non-prescriptive with regard to file format or structure, but with special attention given to preservation and technical metadata. Hub & Spoke METS Profile 4

7. LRCRUD Client & Service  RESTful Web service API for repositories  Client integrated into Hub and Spoke tools  Support for DSpace, EPrints, and Fedora  Specification and API for extending the tools for other repositories Lightweight Repository Create/Retrieve/Update/Delete LRCRUD Client LRCRUD Service Repository Repository- specific calls REST Calls Create/Retrieve/Update/Delete SIP Hub & Spoke Tools 7

8. To Hub Packager  Creates Hub and Spoke object from repository DIPs or from scratch, given content files and metadata  Support for DSpace, EPrints, and Fedora  Extendable plug-in architecture for creating new packagers To Hub Packager Hub Package Repository DIP 8

9. Descriptive Metadata MARCXML MODS DC T T T T PREMIS Event: 'METADATA_TRANSFORMATION'  Descriptive metadata is part of the representation, not just about the representation  Format conversions expressed as PREMIS Events  MODS (required) as primary dmdSec  All others as alternate dmdSec – including intermediate formats 9
