Data format |
Download the schema format description. The data schema (created e.g. by the schema extractor) is a custom-formatted JSON file listing the classes and properties, as well as subclass information, information about property applicability to class instances, and cardinalities. Check code repository for a data schema example. Note. There are services for saving the schema as OWL ontology from within the ViziQuer/base tool. |
