  1. Real music libraries in the virtual future: for an integrated view of music and music information Michael FingerhutIrcam – Centre PompidouParis, France Contactforum: Digitale bibliotheken voor muziek. 3/6/2005

  2. Need to organize and provide access to: Collections and archives Physical, ephemeral and virtual objects Local and remote Audiovisual, symbolic and textual data Data and metadata (and metametadata, metametametadata…) Approach Domain-specific (music information) Share resources Provide structured and efficient search and navigation tools In collections In objects Provide appropriation tools (remember, analyze, explain) The new challenges facing librariesand their users

  3. A (simplified) map of music information data audio multimedia similarity interpretation form orchestration melody polyphony key harmony tempo instrumentation segments chords dynamics rhythm pitch duration timbre intensity spatial room audio programs user rights owner cognitive, social taste, mood DRM interaction annotation musicology playlists analysis similarity metadata synchronization, summarization theory genre indexation pattern extraction, form recognition… semantic information motives structure features feature extraction,identification musicalacoustical characteristics concept → sign → signal → sign → concept … symbolic fingerprint pitch, voice extraction metadata data automatic textual sound text score stored data lyrics about symbolic digital OCR paper physical performance (live, recorded) publications music librarian work abstract performer author composer

  4. Webreference Federating internal contents and information sources Common search point OAI protocol (name, title, instrumentation, date, place…) Library catalogue Audio concertarchives Concertnotes Biographies,articles Calendarof concerts Read Read Where When, where Listen

  5. Federating contents and information sources of distinct organizations Common search point OAI protocol (name, title, instrumentation, date, place…) Organization1 Organization2 Organization3

  6. Characteristics Distributed catalog vs. directory Domain-specific search vs. googling Sharing metadata Distributed search Z39.50, ZING… “Real-time” Harvest metadata OAI (Open Archive Initiative) Light How to share data (full-content search) Share the indexes Underlying software: SDX Open source search engine and publishing framework for XML documents Includes OAI Browse, search, thesauri http://adnx.org/sdx/ Current projects Sharing contemporary music resources within and across institutions Sharing ethnomusicological collections across institutions Technical information

  7. Example: ethnomusicological portal

  8. Displaying musical structure and navigating within a document

  9. Displaying semantic structure of a sound recording and navigating within it

  10. Arbitrary multipage background Arbitrary shapes, images and text Layers (overlays) allowing selective display at play time Timed events Automatic synchronization with different audio files using cue points Cursor (forward, backward) Play same annotation with distinct audio (video) files Multiwindow (Automatic tools) Annotating multimedia documents for analysis and comparison

  11. Efficiency (and rights): produce music excerpts via automatic summarization 1. Find which parts sound like other parts (timbre similarity, e.g.) 2. Extract segments 6 5 4 3 2 1 0m0s 5m25s 3. Produce summaries 0m0s 5m25s similarity matrix The warmer the color (red = warmest), the more similar Courtesy of Geoffroy Peeters, Ircam

  12. Less hard-core cataloguing Automatized procedures Not just “google” collecting Collection building Selection of documents Validation Valorization Virtual works Virtual collections Physicaland virtualmediation VRML, etc. Informationspecialist The new librarian
