Use Cases for Taxonomies
based on SKOS Core + SKOS-XL

3. SKOS is used
for taxonomy
management
in many
different
industries
▸ SKOS Core
With SKOS Core, only concepts can be used as resources;
labels are only ‘attached’ to concepts and cannot be described in more detail
or related to each other

4. With SKOS-XL,
labels can
become
resources
▸ SKOS-XL - the main difference
to SKOS Core
With SKOS-XL, each label can become a resource.

5. Use Cases for
SKOS-XL
▸ Introduce attributes for labels
With SKOS-XL, each label can have specific attributes,
e.g. ‘isSymbol’ or ‘isISOcode’, etc.5

9. Use Cases for
SKOS-XL
▸ Multiple and consistent
(re)usage of labels
With SKOS-XL, each label can be (re)used at multiple points of a
thesaurus. This helps to keep a taxonomy even more consistent
while labels are used in various contexts.
