Conservation Audio Using METS: The Sound Directions Project Robin Wendler r_wendler@harvard.edu Harvard University Library 7 May 2007

Slide 2

Goals “ Develop best practices and test rising measures for archival sound protection and capacity in the advanced domain” Establish programs for computerized sound safeguarding at every college that will empower us to proceed with this work into the future, and which will deliver interoperable results “ Preserve discriminatingly imperiled, exceedingly important, exceptional field recordings of extraordinary… interest.” Participants Indiana University (Archives of Traditional Music) Harvard University (Archive of World Music)

Sound Directions: Scope of interoperation today Preservation filing and trade just No end-client conveyance obliged No enlightening metadata obliged Exchange  Ingest  Re-send out

Slide 6

Standards Used in Sound Directions Audio document position AES31-2-2006 (Broadcast Wave) Audio choice rundown AES31-3-1999 under amendment to incorporate markers Archival bundling METS Technical metadata AES Audio Object (in draft) Digital provenance metadata AES Process History (in draft) Indiana utilizing current adaptation Harvard utilizing new draft

Slide 7

Digital Audio Object = What? Tune? Execution? Catch Event? Side/Track? Physical Item? For archival safeguarding, we make one METS for every unique bit of media. This does not forestall presentations in light of different structures.

Now we’ve got every one of the parts. How would we make a METS? Populate registry on a document framework Run one instrument (DMART) to develop a sound store bundle mets.xml Including Audio object specialized metadata Process history metadata ADLs Referencing outside records Archival expert sound Production expert sound Deliverable Real Audio SMIL a batch.xml document containing authoritative metadata about the store.

Different desires drive diverse decisions Role of METS for sound Navigation of substance for end clients Navigation of substance for sound architects Interaction of METS and sound gauges Should document references inside AES metadata reflect METS inward structure or unloaded index?

Slide 21

Interaction of METS and sound benchmarks References inside AES metadata: would it be a good idea for them to be right inside archival bundle or right once unloaded? In what applications/connections will the substance be utilized? End clients Audio engineers

Slide 22

Things Harvard wishes it did another way Don’t keep Mac Creator Codes. We plunk in standard ones, not the ones that quite to records in the bundle. Don’t require any. Don’t keep waveform documents New innovation creates them in less than a moment versus 40 minutes earlier. Keep specialized metadata for disposed of middle of the road substance records as metadata, not as substance. Don’t inquire.
