Service-oriented strategy
“Everything you need to know about education in on place.”
• This is solved with technology and not editorial tasks. – Data harvesting instead of editorial tasks (“cut
& paste”)
• We consider ourselves a service provider where our webpage is one of many services.

Utdanning.no
• The website is mainly a metadata portal where the key services that we offer are: – A national centralised repository with Course
descriptions of “all” educations in Norway (course description metadata). CDM
– A national centralised repository of learning object metadata.
– A framework for learning content publishing (new!).

of resources and have 4 times as many users.

Publishing framework
• Utdanning.no offers this as service for external editorial groups.
• Utdanning.no does not want any editorial responsibility. • By now it is offered to a cooperation of local governments.
They use it for three different subjects at high school. • Their ambition is to make the content so comprehensive
that it could replace the traditional book.• The content is partly produced by teachers and partly
bought from publishing companies. • Fag.utdanning.no
