To build a thesaurus
The ‘thesaurus’ table and the ‘Concept’ detailled view provide access to thesaurus construction and management functions.
To start a thesaurus
- Add a top concept
The top concept is tjhe highest concept in the hierarchy to which it belongs. It is represented by a top term. Located at the ‘root’ of the vocabulary, the top concept is an entry point into one of the branches of a thesaurus.
- Add a narrower concept
- To import a list of concept
– CSV preparation file
The file to be imported must first be structured according to the SKOS classes
→ See the section on the SKOS datamodel in the ‘Best practices’ article and the section on importing in CSV format in the ‘Import a thesaurus’ article.

If the identifier (URI) already exists in the thesaurus, the concept to be imported will be rejected.
The identifier (URI) is mandatory to express hierarchical relationships with a broader term, whose own identifier must be indicated in the skos:broader column.

The notations
Notation refers to a code for identifying a concept whithin a classification system. Examples are the Dewey classification system, the Periodic Table of the Elements or the Aarne-Thompson classification of tales.
The chemical symbol ‘O’ is the notation for oxygen:
<skos:preflabel xml:lang=”fr”>Oxygène</skos:preflabel>
<skos:notation>O</skos:notation>
The standard tale ‘Cinderella’ has the number 510A in the Aarne-Thompson classification:
<skos:preflabel xml:lang=”fr”>Cendrillon</skos:preflabel>
<skos:notation>510A</skos:notation>
