1 Scope
The primary purpose of the ISO/IEC 19763 series is to specify a metamodel framework for interoperability. This document specifies a metamodel for registering document models (or schemata). Examples of such document models include:
-
— specifications for XML documents (using XML schema[3]);
-
— specifications for JSON documents (using JSON schema[2]).
This metamodel was developed taking into account the requirements for both XML schema and JSON schema, but is applicable to all current specifications for document models.
