Utdanning.no

• Owned by the Norwegian Ministry of Education and Research.

• The website is a national common gateway that provides easy access to everything you need to know about education.

• Utdanning.no has no governing authority but is coordinating The Norwegian Cooperation of Websites in the Educational sector (SANU).

• Utdanning.no website is all designed on open source software.

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!).

Learning object repository

• Metadata collection harvested from minor collections.

• Norwegian biggest repository for educational digital content. (5500 resources)

• The number of resources and the number of users are increasing steadily. – Since last summer we have doubled the number

of resources and have 4 times as many users.

Strategic process

“Marketplace for commercial and non-commercial producers”

1. Harvest small governmental websites. (ims LOM)2. Fine tune routines for import / export. (API)3. Offer services to 3 part organisations. (Gdata, SRW/SRU, OAI-

PMH )4. Offer framework for Learning content publishing. (CMS)5. Offer harvesting from commercial producers. (ims LOM)6. Offer harvesting mechanism for content and metadata harvesting.

(Atom publishing server. Files + metadata)7. Offer harvesting from a collection of resources for people with

disabilities.

Service oriented repository

• Harvesting of minor collections.• GUI with IMS LOM fields filtering. (HTML) • Search boxes• RSS• Fedora support OAI-PMH harvesting.• SRW and GData search API.• Combination of GData and OAI filtered

To do

• Extend with more service-oriented services.

• More Web 2.0 communication with the end user.

• Connect our repository to international federated search projects. (Fire / LRE)

• Change from the use of open source to become open source.

Behind the scene

• In Norway we use http://bak.domain.noPartner information, what happens

behind the portal? What technology to we use?

• http://bak.utdanning.no instead of

• http://www.utdanning.no

Technology

• Fedora Repository software.

• FEZ administration interface.

• Drupal end user interface. (Todo)

• Solr (Lucene) search engine. (Todo)

• Format: HTML, LOM, DC, RSS

• API: OAI-PMH, SRW, Gdata

• Filtered Harvest: Gdata + OAI-PMH

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
