Technical Operability
ITU : 4 Different levels of interoperability:
ETSI (European Telecommunications Standards Institute) distinguishes four layers:
• Technical interoperability associated with the hardware components / software, systems and platforms that enable machine to machine communication. This layer is centered on communication protocols and infrastructure needed to operate these protocols.
• Syntaxic interoperability associated with the formats and models of data representation.
• Semantic interoperability associated with the meaning of the content, and therefore relates to human interpretation of the content, not the machines. Interoperability at this level implies that there is a common understanding of the meaning of the content exchanged.
• Organizational interoperability associated with the ability of organizations to communicate effectively. Builds on the previous 3 layers. May depend on the culture of the organization.
ITU : 4 Different levels of interoperability:
• Why is interoperability important? – Interchange, Persistence & Migration – Open exploitation: in production and distribution processes – Search: ability to conduct research on several different sets of
metadata in order to obtain meaningful results (OAI-PMH and Z39.50 protocols) and crosswalk., Merging catalogs (Catalogs Union) , Cross search (Cross-system search)
– Navigation between objects
• How to ensure the interoperability of metadata?

Plain text • Fundamental capacity of expression for humans • No loss of information • Poor suitability for computers (aka searches)
Tagging • Low treshhold • Good enough for a single user (delicious) • Moderate precision on large databases • Visibility depends on popularity

Semantic
The semantic modelling of media in the
audiovisual process:
Semantic middleware SaaS
(Software as a Service)
represents the relations: relations need to be qualify in order to classify and browse links,
link actors: each actor has his own specific view on the editorial object. It means adjusting the views to the relations and to the actor that handles them (role and qualifications),
monitor actions: a contextual GUI helps to filter and to optimize the management and the configuration of the process.

Main CONCLUSIONS
Going to SEMANTICS cannot be avoided
The technologies of the SEMANTICS are ready , powerful and easy to use
Modeling SEMANTIC objects is easy and funny
Retrieving & exploiting SEMANTIC objects is easy
The EMPOWERMENT of your assets
can be made in a quasi automatic way!
Progressively, ‘born digital’ works will be created SEMANTICALLY modeled
• The predictable bidirectional compatibility with the ‘Flat’ models
• The predictable persistence & OAIS adherence
• The predictable interoperability & isolation of ‘proprietary’ features
• Powerful contextual searches & exploitation opportunities
• Compatibility with the existing metadata
• Easy presence on aggregation portals
The EMPOWERMENT of your assets gives you:
