Thesaurus view
From OpenKM Documentation
A thesaurus is a book that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which contains definitions and pronunciations.
Thesaurus view is a hierarchical tree structure of SKOS (Simple Knowledge Organization System) folders. SKOS concepts are linked many to many, but are represented as a tree structure.
A document can be linked with many SKOS folders at the same time. Each time some SKOS folder is selected, all related documents will be displayed in the file browser panel. All the major document functionalities are available from this view.
