4 Fundamental Concepts Kahn/Wilensky Framework for Distributed Digital Object Services (1995)

5 CCSDS Open Archival Information System Reference Model (2002)

6 RLG-OCLC Trusted Digital Repositories: Attributes and Responsibilities (2002)

7 Growing recognition that the digital library is an institutional endeavor

8 Digital Curation "IRENE," courtesy of (CC)

9 Enabling digital curators to mitigate risks to their data Abandoning the notion of preservation as place Acknowledging that the curation process begins early

10 Emerging principles First and foremost, preserve the bits "Lots of copies keep stuff safe"

11 Divisions between access and curation continue to blur

12 Challenges 1. Cost and scalability of, e.g., storage 2. New and unfamiliar formats, maybe 3. Scholarly communication and collaboration

13 Repositories Courtesy of (CC)

14 The evolution of repositories collection-building tools (Greenstone, DLXS) display applications with harvestable metadata (DSpace, CONTENTdm) OAIS-inspired monolithic frameworks (Fedora, adore) decoupled micro-services + web architecture (California Digital Library, SWORD, OAIORE)

15 Building trust in repositories

16 How? By ensuring: content will not change except, e.g., for planned format migration derivatives and migrations of content are faithful to the original masters content is authentic and has documented provenance content is accessible via known identifiers

17 Technologies for trust digital signatures persistent identifiers audit trails / provenance metadata content versioning authorization / authentication rights / access control

18 Growing the repository

19 Broad growth electronic theses & dissertations research data learning objects pre-prints electronic records public domain documents

20 Deep growth Incorporating the repository into institutional programs and workflows

21 Acknowledging the tension between preservation and growth

22 Metadata Courtesy of (CC)

23 Serving as a conduit between library metadata and the web's best practices and "2.o"style uncontrolled metadata

24 Outward Contributing authority metadata and schemas to efforts to build a more descriptive web

25 Inward Adding value to services by augmenting them with "crowd-sourced" metadata

26 Emergence of the Linked Data pattern "Use URIs as names of things. Use HTTP URIs so that people can look up those names. When someone looks up a URI, provide useful information. Include links to other URIs, so they can discover more things."

27 Linked Data sites in library-land id.loc.gov dewey.info metadataregistry.org viaf.org chroniclingamerica.loc.gov wdl.org (soon)

28 Challenges Expensive human description efforts do not scale with all the data Will provenance and preservation metadata suffice in the trust framework? To what extent should embedded metadata be used?

29 Interoperability Courtesy of (CC)

30 Much of the recent convergence between library technology and the web has occurred in the digital library context

32 Libraries and cyberinfrastructure

33 Integrating library systems and processes into campus cyberinfrastructure

34 How? Standards and best practices help, as does alignment with technologies from outside libraries

36 Sustain the digital library through a framework of partnerships, institutional commitments, and technology strategies
