Presentation Transcript
project goals
Project Goals
  • Archiving recorded field material from the region around Australia
    • Preservation (longterm storage and backup)
    • Description (metadata or cataloguing information)
    • Rights (access and deposit conditions)
    • Access (providing data online)
    • Training in appropriate methods to support these goals
rationale
Rationale
  • Records of cultural material are themselves becoming endangered
    • (reel to reel tapes are deteriorating, audio-cassettes are becoming obsolete)
  • Such records are held in poor conditions, not catalogued and so unlocatable remotely
policy issues
Policy issues
  • Research policies of participating universities with regard to safeguarding research data
  • Policies of engagement with the Australian region
university of melbourne
University of Melbourne
  • “A core principle is that research data and records should be maintained for as long as they are of continuing value to the researcher and in accordance with the requirements set down by the University, research funding bodies, legislation, regulatory authorities and patent agencies. ..... Recognising that there is a requirement for researchers to retain research data and records, the University seeks to facilitate compliance by requiring each department or unit to make arrangements for facilities to be available for the storage of research data and records. Researchers may either use such storage space or make alternative arrangements acceptable to the supervising staff member or head of department.”

University of Melbourne
  • Encouraging the Melbourne Institute of Asian Languages and Societies and the Asialink Centre to work together to implement the 'Melbourne Agenda', particularly by promoting political, industry and community understanding of Asia in Australia, and positioning the University of Melbourne as a significant East Asian institution.

preservation longterm storage and backup2
Preservation (longterm storage and backup)

Distributed data

  • Mirrored data in different locations using the Australian Partnership for Advanced Computing national facility (APAC) at the ANU.
  • Moved between Sydney and ANU via GrangeNet
  • Stored on tape and hard disk
  • downsampled version provided to depositor (MP3 or similar)
metadata cataloguing info
Metadata (cataloguing info)
  • For discovery / harvesting
  • For assessment
  • For preservation
discovery
Discovery

Conforms to Open Languages Archives Community (OLAC), which itself conforms to Dublin Core

Export to XML

  • PARADISEC is a static repository of OLAC conformant metadata.
  • BWF encapsulated data

Use of controlled vocabularies

  • language names / codes, from Ethnologue
  • Country names / codes, ISO
  • Roles (OLAC)
  • Etc

Database used to constrain entry (FMPro)

discovery1
Discovery

Ability to locate data via a standard search mechanism. Metadata in OLAC format

Allows a user to identify material using standard descriptors

Assessed (ie not just digitised) data also listed

Tapes undiscoverable

Tapes + catalogue discoverable locally

Tapes + catalogue + web discoverable globally

Tapes + catalogue + web+digital objects discoverable globally

and available

(subject to permissions)

data assessment metadata cataloguing information
Data assessment (metadata / cataloguing information)

Assessing tape collections for ingestion (=digitisation), triage based on:

- state of current media

- content (regional, endangered)

- state of current storage

- share of services between partner campuses

Selection based also on individual items within a

collection that may have special value.

data preservation metadata cataloguing information
Data preservation (metadata / cataloguing information)

Tracking data through the process of ingestion and duplication for depositor’s copies. Metadata exported to BWF to transcript level

  • Digital preservation copy stored on 100 GB digital access tapes in the MSS at the University of Sydney
  • Mirrored at the robotic mass storage system at the ANU (APAC)
  • Digital data in the mass storage system is automatically backed up and migrated to new tapes on a regular basis.
  • Examples
technicalities hardware
Technicalities - Hardware
  • Quadriga AudioCube 4-II has 2 Pentium III 1Ghz processors, 256 MB RAM, 36 GB audio hard-disk (shuttle), and a 9GB system hard disk.
  • Digital Audio Denmark ADDA 2402 converter box, located between the analogue playback equipment and the AudioCube, handles analog-to-digital conversion.
technicalities software
Technicalities - Software

Wavelab sound editing software to record the audio data at 24-bit 96khz .wav files (PC-standard PCM raw audio files).

Audio File-Inspector

  • converts standard WAV-files into BWF
  • analyses them for maximum and average level, signal-to-noise ratio, dynamics and phase correlation, with results being recorded automatically and saved as metadata in the ‘quality chunk’ of the BWF file.
  • BWF files are then digitally 'sealed' with a File Security Code to maintain the integrity of the audio and metadata.
rights access and deposit conditions
Rights (access and deposit conditions)
  • Deposit / access forms
  • Embedding rights information in the processing system for eventual automated access or restriction of access
access providing data online
Access (providing data online)
  • Data store
