Vocabulary Bank •
Central portal for presenting, downloading, referering nad mangement of vocabularies.
•
For humans (website) and applications (API).
•
Vocabulary is a list of values for a specific data field (code list, classification, taxonomy, ontology, thesaurus).
•
Kennisnet is manager of the vocabulary, but the semantical responsibility is for the autority (SLO, COLO, a.o.).
•
At this moment mainly for metadata, especially classifications For example educational level and disciplines.

The Vocabulary Register
Expertisecentrum Standaarden voor het Onderwijs
Relation vocabulary Mappings (cross walks) • Mapping is a relation vocabulary to be able to transform data based on the vocabulary, e.g. metadata. • A mapping is published apart from the vocabulary; each mapping has an authority. • Relations have type from ISO 5964 “Equivalences” : exact, inexact, partial / singleToMultiple of nonexact. • In each Mapping for each term from one vocabulary is determined which terms from the other vocabulary are related and the relation is described. • Also make a mapping for the transformation the other way around. • The need for mapping will increase in the future.

‘Hot’ in NL: metadata streams
Expertisecentrum Standaarden voor het Onderwijs
New insights In the ‘old days’: •
metadata about a L.O. is added by the content owner (publisher f.e.) or content collector
In the new world: •
In the content chain, other members can add usefull metadata as well – Not only ‘social metadata’, but LOM-metadata – F.e. by creating a learning line

‘the egg of Columbus’ in useability (for now): Curriculum-relations
•
Amount of learning objects is exponentially growing – Edurep has 50+ repositories !
•
Teacher does need a learning line, not single learning objects
•
We need the connection between a single learning object and the learning line (curriculum)
