Conformance Targets

NIEM-conformance of JSON data is primarily focused on the relationship between the data in the JSON file and the definitions established by a NIEM-conformant schema, e.g., the schema defined by a NIEM IEPD.

There are two forms of conformance of a NIEM JSON document to a NIEM-conformant schema:

ID	Code	Conformance Target	Description	Spec
STRICT	STRICT	NIEM JSON document strictly conformant to a schema	A NIEM JSON document strictly conformant to a schema is a JSON-LD document that may be assigned a one-to-one correspondence to a conformant instance XML document valid against a conformant schema document set.	Link
LAX	LAX	NIEM JSON document laxly conformant to a schema	A NIEM JSON document laxly conformant to a schema is a JSON-LD document that may be interpreted using the RDF vocabulary defined by a conformant schema document set.	Link
