1. The Stanford Digital Repository in the Digital Library Ecosystem Katherine Kott, Stanford University RDAP Institutional Repository Panel Denver, CO March 31, 2011

2. Framing the IR Discussion Ed Summers (LoC) adapted Ranganathan’s five laws Repository objects are for use Every reader his/her repository object Every repository object its reader Save the time of the reader [service?] The repository is a growing organism

3. First Generation Repository Development Violated several laws Heavyweight requirements for depositors did not scale (time intensive) Difficult to return objects to depositors in “native” state (difficult to enable use, reuse) Monolithic design prohibited adjustment without total redesign (no capacity for organic growth)

4. SDR 2.0 Infrastructure Support a “growing organism” (scalable) Lower barrier to deposit Save the time of the [depositor] Base development path/priorities on use cases Repository objects are for use Every reader his or her repository object Every repository object its reader

5. The IR within the Digital Library Ecosystem

6. Microservices in the Ecosystem
