Offer Management
Providers of learning resources may wish to
specific offers for their learning services. An offer has a specific duration
and includes usage conditions and rights associated with a learning service.
An offer might be target audience-specific. Educational nodes might want to remove
or alter an offer of a learning service. Specific input shall also be
provided by the Ten-A project.
Specification of Federation Scenario
In a smart space for learning, or any network
of repositories for learning, educational nodes are federated. In such
a network dependencies between the educational nodes exist, which need
to be reflected by the infrastructure. For example, currently in Edutella
the routing of search request is based on schemas, but such a routing
might also be based on federation agreements. Federation agreements might
also be the source for access rights management and transitive offers.
Query Interface
The query interface specification is still in
a proposal stage. The specifications need to be refined and first prototypes
implemented.
Session-based Communication
When one of the components of the interface
framework are called, communication goes through a sequence of calls (e.g.
the availability of a search interface is checked, the search interface
is called to request the search languages supported, finally a search
request is placed). A session-based communication framework shall be considered.
Input can be expected from Universidad Politécnica de Madrid, IMC, and
Allweb. The OASIS business transactions protocol might be additional valuable
input for this task
Input from Implementers on Access control
Access control is one crucial part of the specification,
which has not been implemented using SOAP. Input is expected from developers
would be crucial to further shape this section of the document.
Standardizing Interoperable Systems
The specification should communicate clear,
which system properties are required to become interoperable. A distinction
between MUST properties and MAY enhancements should be made. This could
ultimately lead to tools for conformance testing.
