Flexible Metadata
Element Sets
Metadata Element Sets Provided:
• Standard Dublin Core (DC)

• Learning Object Metadata (IEEE LOM / NL LOM)
Objects are organized in assets, media files and collections.
Metadata Harvesting using OAI-PMH

CRUD REST-calls on all objects possible. i.e.:
• POST /asset/create?user=John
• GET /asset/$asset_id
• POST /mediafile/$mediafile?filename=NewName
• POST /collection/$coll_id/delete?user=John



Transcoding Services

Based on FFMPEG a complete, cross-platform solution to record, convert and stream
audio and video. It includes libavcodec - the leading audio/video codec library.



Access Management
Screening
Default: Media is accessible for everyone.
Option to set access restrictions for playing media on the
following properties:

• Domain, or group of domains:
i.e only accessible from .surfnet.nl
• Realm, or group of realms:
i.e. using SURFfederation
authentication infrastructure
• User, or group of users:
only give rights to user=john or
group "class-24"



Search Services
Simple Search:
• GET /asset?owner=John
• GET /asset?collection=7
Advanced Search using CQL level 2 :
• “(dc.title = foo OR qdc.title_alternative = bar)”
• “NOT (dc.title = foo AND dc.title = bar)”
• “^cat ^dog tree^”

MEDIAMOSA TRANSCRIPTING TECHNOLOGY

Disclosure
of
audiovisual
archives

• The number of AV-archives on the Internet
increases rapidly
• Archiving is not enough: disclosure and reusing is
required!
• The use of speech technology is needed
(Reduce human effort).

UK National Film and Television Archive, Berkhamsted

Adding metadata, the traditional approach:
Manual annotation

Huge amount of work
and no time-coded relations with video



Adding metadata, the new approach:
Using speech-to-text technology for
metadata generation
Audio Extraction

Speech Recognition
(Speech-to-Text)
Time-coded Transcript

Indexing and Search:
Search on fragment level

• Dutch education is looking for alternatives:
- MediaMosa in the Cloud?
- MediaMosa as a service of SURFconext?
- Using MediaMosa as an institutional service

• MediaMosa is being used by others:
- Archipel (Belgium)
- E-Campus (Norway)
- Cineca (Italy)
- Arnes (Slovenia)



Next Steps
MediaMosa roundtable conference: 17 nov. 14.00-16.00 @SURFnet

The role of the Community becomes more and more important!
