SCHAC Schema IIEvolution and usage

Some uses of SCHAC (I know of)

FUNET is using ituma.es is in the process of phasing out iris* attributes thathave schac* equivalents or improvements, likeschacPersonalUniqueID and schacPersonalUniqueCode,in favour of irisPersonalUniqueID or internal values foreduPersonEntitlement.uma.es is also preparing to load schac attributes into theinstitutional SmartCard, through attribute certificates.Others? Will you please come forward?I think I know who you are.

URN registry proposalTracking contents of values for URN based attributes

Controlling the URN explosion, which is not necessarily bad.

Owner’s LDAP directoryThe objects would be stored in thenamespace owner’s LDAP directory, in orderto ease both maintenance and local queries.

Human interfaceA web query system in the lines of theSchema Registry Project, though with adistributed flavor.Any namespace owner local registryinterface should be able to follow the LDAPURIs in the delegation objects, forpresenting public URN values, from anyparticipating registry, perhaps in the locallanguage.

Machine interfaceApplications. local or foreign, should be ableto query the directory and get informationwith the appropriate level of access. Forexample, for obtaining local languagehuman representations of a given URNvalue.

DDDS?It could be used for transforming URNnamespaces into information for finding theappropriate service to query about URNvalues.

SCHAC based federated Student Registration Systeman application with Bologna inside

Some crazy ideas

(or not so crazy?)

Bologna is about moving lots of students around EuropePresent systems tend to store a lot of information locallyFederations may be used for more than just IdMWhy not use a federated service for sending studentcredits back to their home organisations?
