3. May 23 - 26, 2006 3 RUcore Objectives To provide seamless, perpetual access to digital collections -- our resources and the resources of others. To develop a flexible framework of “core” capabilities providing the enabling infrastructure, interoperability, and sustainability. To create an information architecture which will support multidisciplinary collections.

7. May 23 - 26, 2006 7 Information Architecture – The Collection, the Digital Object, and Metadata In its most general sense, a digital collection is simply a grouping of objects according to some criteria. Types of digital collections in Rucore Explicit – A digital collection whose object membership is specified explicitly within the descriptive metadata. Dynamic – A digital collection of objects which are grouped according to user specified criteria.

9. May 23 - 26, 2006 9 The Digital Object The digital object is the basic unit of management, encapsulating all essential information about the “document” to be disseminated and preserved, including: Descriptive metadata (based on MODS*), administrative and event-based migration metadata Byte streams in both presentation and archival formats (non- proprietary, infrastructure independent forms) Persistent IDs and digital signatures Software for dynamic behavior * Metadata Object Description Schema

May 23 - 26, 2006 11 Data in a Multidisciplinary Repository  Data Characteristics: Born-digital, no corresponding physical artifact Specialized metadata standards – DDI, FGDC, etc. Large – gigabytes ranging to terabytes Life cycle changes – versions, editions, re-purposing, etc. Many contributors, spread over wide-area network Users from many different disciplines
