\acdhOeaw\utilOntology

Ontology cache class.

Fetching full ontology (resolving class and property inheritance) from a triplestore is time consuming. At the same time the ontology changes rarely. Thus caching is a perfect solution.

The ontology is cached in a JSON file (path is taken from the repoConfig:ontologyCacheFile config property). It is automatically refreshed if the repository resource storing the ontology owl (as set in the repoConfig:ontologyResId) modification date is newer then the cache file modification time.
