Österreichische Tage der Digitalen Geisteswissenschaften
save the data - workshop on digital repositories, Dec 2nd 2014
Johannes Spitzbart
Phonogrammarchiv, Austrian Academy of Sciences
Collecting, preserving and documenting primary audiovisual
research sources (unique) and making them available for research
use
Scholarly research (ethnomusicology, ethnology, linguistics, context
& discourse)
Technical research & development (standardization, i.e. IASA-TC,
preservation, replay & digitization of recordings, patent “Method
for Reconditioning of Data Carriers”) and training
Role in the digital research infrastructure:
Digitization, long-term preservation, data accessibility
Metadata capture, comprehensive documentation, database
access, searchability (online catalogue)
Manually managed system:
File Server – RAID 10 (= mirrored) HDD array, 40TB (usable capacity); LTO Tape Library
(two backup copies)
Eternal preservation through continuous data and format (if needed) migration
Checksums for file integrity check
Pros:
easy files/folder management, in-house maintenance, flexible (independent from
proprietary management software; hosting of any file format), probably easier disaster
management
Con:
additional effort for manual file/folder management and linking to database (human
resources)
Network Switch
1-Gigabit Ethernet
Content:
Several workstations
•
Digitized (approx. 50%) tape/disc collection (audio)
•
Born digital output of supported external & own
projects (audio)
•
Digitized acquired collections (audio)
Gigabit Ethernet
file servers
•
Workspace (for temp data)
2 independent, scalable hard drive storage units in
storage area network environment (mirrored hard
drives, RAID 10)
Data backups managed by system administrator
Tape library with LTO (=tape
data storage) drive
MySQL DB, PHP frontend, custom developed (daily backup onto
storage system)
Elaborate structure due to archival documentation needs
(comprehensive metadata capture)
Taxonomies & controlled vocabularies (Hornbostel-Sachs, languages,
ethnic groups, etc.)
Different access levels (visitors read only, admin for taxonomies and
CV)
AV playback in browser (MP3, MPEG-2)
English version (work in progress)
Content:
Comprehensive documentation
(technical, content descriptive and
contextual) at item level (=recording)
which is a prerequisite for accessibility
and potential use
… slimmed down copy of in-house database on dedicated
“exposed” server
Reduced data set & short samples
Focus on usability and sophisticated search possibilities
Connected to Europeana through Dismarc (weekly updated)
Open Access?
Legal constraints
(Intellectual property rights)
Ethical issues (sensitive content)
full length online publication not possible
to date
