Layton principles of digital heritage

  1. 1. Second International Conference on African Digital Libraries and Archives (ICADLA-2) University of the Witwatersrand : 17-18 November 2011 Roger Layton CEO, Roger Layton Associates 1
  2. 2. We are at a unique point in history….ours is theONLY generation which has to shift fromphysical to digitalAND WE ONLY GET ONE SHOT AT THIS!We need to plan for a future in 5, 20, 50, 200 and 500years and beyondCurrently we cannot see beyond 2 years into thefuture! 2
  3. 3. ETHER = ETernal HERitage “How do we build computing systemsthat last forever?”Heritage : the ONLY discipline with an eternalagendaThe most exciting area to be in in ICT atpresent. 3
  4. 4. Tangible Intangible Documentary Knowledge OBJECTS Oral History Libraries Scientific Museums Archives Indigenous Engineering SITES Knowledge Oral History Archaeological HealthBuilt Environment Indigenous Knowledge Data SetsWITHIN THE DIGITAL WORLD, ALL HERITAGEOBJECTS START TO LOOK THE SAME 4
  5. 5. Mechanisms Policy Implementation recommendations27 core statements Strategy Repository Contracts Access Digital Heritage Preservation Metadata Body of Knowledge (DHBOK) Practical guidelines 5
  6. 6.  Principles Participant s Processes Practices Precedents 6
  7. 7. participants processes Products / Practices Scoping Audit Custodian Strategising Digitisation strategy Planning Project plans Preparing Prepared environment Producer Capturing Digital objects (e.g. scanning of glass negatives) Describing Digital masters (rich digital package with provenance) Loading Logs Repository Storing Digital repositories Accessing Search requests / results / user interfaces Consumer Using Repackaged products 7
  8. 8.  AS-IS Analysis • Stakeholders, Collections, Programmes, Capacity, Skills, Documentation, Systems TO-BE Design • Institution Identity and Structure, Internal Policies and Procedures, Prioritisation Policy, Programme/Project Structure, Skills Development Plan, Resource Plan, Standards, Repository Plan, Preservation Strategy, Disaster Management Plan, Funding Strategy, Sustainability Plan, User Experience Goals, Performance Measurement 8
  9. 9. A common set of principles that embody theunderlying qualities and enduring values thatdefining what we should be aiming for thedigital heritage…These principles should be valid in 50, 200,500 years into the future…The role of science fiction literature ininforming our long future. 9
  10. 10.  When confronted with key decisions that do not appear to have a clear path ahead – we need principle-base guidance as an aid The Principles are key factors to inform the development of a Digitisation Strategy and other decisions in the digitisation life cycle of processes Principles should be self-evident and obvious to the reader…should not be a shock 10
  11. 11. “Any best practice structure is required tohave an underlying set of principles that arewidely accepted”Each institution should make explicit whichprinciples that they will user and why, and howthey will be used 11
  12. 12. “Standards must be used where possible toenforce best practices and to enhanceinteroperability and these standards shouldbe continually reviewed and refined”Each institution must select the standards they willuse, from an agreed list of acceptable standards,and must justify why these are suited to theirneeds 12
  13. 13. Digital heritage should not been seen as acollection of disconnected files and folders butshould contain powerful semantics that canenhance and can embrace the context andmeaning of the digital objects and render themcapable of being connected in ways notanticipated at the time of their creation. Web 3.0 : Semantic Web : Linked Data 13
  14. 14. At the time of digitisation it is essential toconsider how semantics will be built into thedigital object to embed maximum meaning –beyond metadata.OUR CASE STUDY : Massively linkedbiographical records of victims of apartheid(Oral History Conference 2011) 14
  15. 15. “Heritage is best managed in collections,and this includes the digital heritage”Shift from physical to digital to virtual collectionsDecisions on digitisation should be preferably atthe level of collections 15
  16. 16. “The growth of digital content appears tohave no upper bound as everyone becomesa producer of such content, and as directsensing and record systems increase inusage.”There is too much data being generated by toomany people and stored in too many placesLittle control over born-digital government records 16
  17. 17. “The protection and control of intellectualrights is a core economic principle of ourmodern world. This applies no matterwhether there are commercial rights or openrights associated with digital content.” 17
  18. 18. In the rapidly expanding world of digitalcontent, there is an increasing need foraccess to valid, authentic, and reliablecontent.Provenance of digital content will becomethe distinguishing factor between trustedand untrustworthy repositories. 18
  19. 19. All records are essentially massively connectedand these connections between the items willbecome more important than inventory lists as wemove into a semantic future.Derived from “The Glass Bead Game”, HermanHesse, 1946.Connections within and between repositoriesContinental structures : Europeana 19
  20. 20. “Ethical consideration arise frequently indecisions on the digital heritage and it isimportant to have an explicit stance in theirDigitisation Strategy on how such decisionsare treated.” 20
  21. 21. “In the absence of anything to the contrary weshould expect that what we consider today tohave enduring value will be valid for futuregenerations.”Institutions must explicit plan for migration offormats and repositories in protecting the contentforever.Forever is a long, long time. 21
  22. 22. “Everything is always changing in the digitalworld. We cannot stop this, but we canadapt.”The only constant is change.Adaptation strategies must be a corecomponent of a digitisation strategy. 22
  23. 23. “There is a strong association between thecommunity and heritage since communities areowners, producers and consumers of heritage,and in the case of the oral history they are alsothe long-term custodians of this heritage.”Every custodian MUST engage with itscommunities 23
  24. 24. “The ultimate reason that we create digitalheritage is to allow this to be shared withothers, both current and future.”The largest future community of users are high-school students 24
  25. 25. “Digital repositories run the risk of normalisingcontent and creating uniformity. A consciouseffort is required to encapsulate diversity anddifferences.”We can use digital content as a means to enlivencultural identity.OUR CASE STUDY: Access to heritage for tourismpurposes, in all local languages which are normallyspoken but not written or read. 25
  26. 26. “Future engagement with history will bemostly through digital technologies – ourdecisions of today have considerable impacton the future.”What will be lost to future generations?Can we control this risk today? 26
  27. 27.  Universal Principles should be timeless They will guide the development of our • Digitisations strategies • Decisions on prioritisation, methods, technologies, metadata, interfaces The Principles will be subject to peer review, as well as rest of the DHBOK 27
