Richard,
Very interested in your angle here. Concur with others on this list that this
is indeed synergistic with Kendra Initiative vision [1]. EU funding for Kendra
is imminent [2]. Currently on world tour evangelizing Kendra so time
constrained [3]. However, in London for a media networking party on October
12th [4]. Do come along and meet other media visionaries and we can also chat
about moving this forward. Moving website to Drupal CMS in the new year so hope
that Kendra ecosystem will flourish with user participation [5]. And will
create more formal ways to join and raise funds - there is good support [6].
Solutions to an interoperable open media marketplace need to be cross industry,
cross sector, cross media and cross format.
Hope to see you on the 12th...
Cheers Daniel

*Subject:* [backstage] DMI prototype - a global media hub
Having left the BBC back in February when I was aware of initial
rumblings of the Digital Media Initiative, I was pleased to see that the
BBC released information about DMI through Backstage. Joined-up
end-to-end production of cross-media services will deliver a whole load
of new and exciting services to the user and DMI is about providing the
core technology for the capture, production, distribution and archive to
do just that. For some great examples of the services of the future, see
the use cases developed as part of the micro-navigation of data under
development by “JUMMP: Joined Up Metadata for Media Playback”
<http://www.jummp.net/>
I have a very ambitious idea about implementing a prototype version of
the DMI model outside of the BBC using only open-source tools and open
standards, possibly hosted in an environment such as the Amazon Elastic
Compute Cloud with the Amazon Simple Storage Service
(<http://www.amazon.com/gp/browse.html?node=3435361>). My vision is to
create a global media hub using web services. Rather than using the data
model released by the BBC, the prototype would map the concepts
contained in the model to existing open standards, such as:
* Advanced Authoring Format and Material Exchange Format (AAF/MXF)
for wrapping essence (video, audio, data) with its metadata
(<http://www.amwa.tv/>), including edit decision lists, as
supported by Avid, Quantel, Adobe et al.;
* Ingex for low-cost content ingest of file-based content
(<http://ingex.sourceforge.net/>);
* Descriptive Metadata Scheme DMS-1 – a standard and extensible set
of metadata to use in describing production content (SMPTE 380M
downloadable for a fee from <http://store.smpte.org/>), which can
be mapped to any of the following:
o Dublin Core (<http://dublincore.org/>),
o TV Anytime (<http://www.tv-anytime.org/>),
o MPEG-7
(<http://www.chiariglione.org/mpeg/standards/mpeg-7/mpeg-7.htm>);
* MPEG-21 for expressing rights management information
(<http://www.chiariglione.org/mpeg/standards/mpeg-21/mpeg-21.htm>);
* MXF Mastering Format – for management of multiple versions of the
similar content (different languages, title sequences for the same
core video content etc.) (also <http://www.amwa.tv/>);
* Open Document Format for scripts, financial data, presentations,
diagrams etc. associated with a production
(<http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=office>).
All of the above standards should be generic enough to avoid the need to
commit to any specific codec. What surprises me is that the data model
as released by the BBC makes no external reference to existing standards
such as those listed above. Surely this conflicts with a stated aim of
DMI ... that it should “support open standards”?
So what is my motivation? I am about to release an open-source API for
AAF in Java that can be deployed to JBoss
(<http://www.portability4media.com/publications/p4m_ibc2007_handout.pdf>)
and this would be the ultimate project to test it with. My concept is to
set up a load-balanced cluster of JBoss application servers, possibly
configured as a JBoss ESB, and to create process orchestration driven by
JBPM (see <http://www.jboss.org>). Business processes can be then be
mapped to a common core of atomic media services, such as transcoding,
metadata management, media asset management etc.. Behind this all could
sit a clustered MySQL database and perhaps even an Apache Hapood store
for large essence files.
Resources such as the Amazon cloud, access to open specifications that
require a fee to access them or other computing resources do not come
for free but the initial costs of prototyping would be relatively small
and could be sponsored. Eventually, if the prototype proved valuable, it
could be made available commercially on a pay-as-you-go basis at a
margin above the Amazon or other hosting fees. For the BBC, this
provides a parallel implementation of the system to be built by their
chosen technology partner(s), reducing the corporation’s risk. For
anyone involved in the project, it would offer the kudos of being at the
forefront of the creation of a world-class digital media hub.
What do you think? Has this been done before? Anyone interested in being
involved?
Richard
