    What is a digital archive?

    Two essential dimensions
       • Long-term Preservation of all resources and relations
       • Accessibility and Interpretability
Why preserve?
• face the loss of our cultural memory on electronic media
       UNESCO: 80% of the recordings about languages and cultures
                are highly endangered

There are no guarantees for preservation but we can increase chances of survival
      • store everything in a well-organized repository
      • take care of redundancy, migration and curation on various dimensions
      • establish organizations that take responsibility

          Digital Archives are living Entities!
Live Archives Concept: allow enrichments (standoff), relations etc
         What is in MPI’s archive?

• Endangered Language Documentation resources
    –    Representative record of a language in its cultural context
    –    Crucial is the active involvement of the community
    –    May help in maintaining and revitalizing languages
    –    Therefore: trend towards complementing linguistic information with
         ontological one in collaborative spaces

• Child language, bilingualism, gesture, sign language, corpus
  spoken Dutch, sound corpora, second learner corpora, etc.

Mostly annotated audio/video recordings
   30 Terabyte, 53.000 AV resources, 24.000 annotation files,
   60 Mio annotations, lexicons, sketch grammars, etc.

All from a large number of depositors

      Still in a download first paradigm – not cyberinfrastructure usage
          (result of an ESF/NSF workshop)
      ‘Download first…’ problems and disadvantages

• Tool and format updates are propagated to users at a slow rate
    ’legacy’ formats offered to archives pose an increasing
     burden on archives or tool builders (conversion/migration)
    New techniques slowly spread through the community

• Orchestration between tools becomes much more difficult if not
• Users need to install tools locally

        Can we provide more incentives on the tools side?
          How to extend LAT?
• Paper dictionaries’ limited usefulness in language maintenance &
   language revival (Manning et al., 2000)
• “Linear” lexicons not at all interesting except for linguists
• Speech community may prefer explicit semantic acces and links, possibly
   of a wide variety of types (i.e. beyond formal systems)
• Semantic view not limited to lexicons, but should include all fragments

Therefore, introduction of conceptual spaces, where concepts are
 related to others anchored in language illustrated with multimedia

Extension of LAT with ADDIT and VICOS
 towards cyberspace paradigm
          relations between arbitrary fragments
          VICOS (Visualizing Conceptual Spaces):
          relations within and across lexicons
          and easy visualization

make VICOS a collaborative tool
          ADDIT: Commentary & Relations

• allow authorized people to make arbitrary comments on and relations between
  object fragments
• visualize them in tools and via VICOS
      VICOS: Lexical relations & navigation

• Allow users to create relations within and across lexicons
  across: cognate sets etc
• Visualize and allow easy navigation in conceptual spaces
• Empower community members to actively describe their L&C
  and to learn from such resources
   – Decide which words offer key access to cultural concepts
   – Technology needed to link words (and the associations they
     evoke) to other words and to all sorts of relevant fragments
• Conceptual Spaces = informal ontology of fuzzily-defined
  concepts and relationships
       • But where “concepts” are anchored in corresponding
         formal lexicon entries
