Flexible Metadata
Element Sets
Metadata Element Sets Provided:
• Standard Dublin Core (DC)
• Qualified Dublin Core (QDC)
• 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^”
http://www.loc.gov/standards/sru/specs/cql.html

Support for Apache SOLR as alternative search engine!

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
http://www.ﬂickr.com/people/footage/


Adding metadata, the traditional approach:
Manual annotation

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


Adding metadata, the new approach:
Exploiting Speech technology for
metadata generation
Audio Extraction

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

Indexing and Search:
Search on fragment level

DEVELOPMENT MEDIAMOSA FRONTEND
• Support for basic functions like:
federative login, screening, uploads, transcoding, metadata, playback,
collections, search.

• Works together with MediaMosa 3.x.
• Based on Drupal CMS and makes use of the MediaMosa Construction Kit
(Drupal Modules).

• Skinable: easy to change template to change look and feel.
• Installable as a ‘ready to use’ frontend application or as a SURFconext service.


Next Steps
• SURFnet funding for development ends 1-1-2012
• SURFnet is ending enduser services like SURFmedia as of 1-1-2013
• Dutch education is looking for alternatives:
- MediaMosa in the Cloud?
- MediaMosa as a service of SURFconext?
- Alternative video services as a service of SURFconext?
- Using MediaMosa as an institutional service?

The role of the Community becomes more
and more important!

• Future of MediaMosa depends on it.
• Secure commitment from educational
institutes.


MediaMosa Funding
• SURFnet/Kennisnet Innovation Program (until 1-1-2012)

• Sponsoring from SURFnet / Institutions /
Partners / Developers
• Contributions from MediaMosa Community

SURFnet’s decision to end enduser services like
SURFmedia will boost the uptake of MediaMosa.

The role of the Community becomes more and
more important!

MediaMosa is there to stay!
