16		-As stated above, openMINDS supports JSON-LD as serialization format for the metadata representations (instances) of its schemas. In the following we will briefly explain the JSON-LD syntax essential for writing a correct openMINDS instance.

19		-Let us first start with the example of an openMINDS core schema that is not linked to any other openMINDS schema: the ##ContactInformation##. According to its schema template (cf. its HTML), the only required property for a contact information instance is ##"email"##. Nonetheless, every valid JSON-LD needs two more properties: ##@type## and ##@id##.
