While MetaConfigurator primarily focuses on the local JSON schema and data files, it provides basic support for external references. External references allow you to include content from other files or URLs into your schema or data, enabling modularity and reuse.
Currently, the data tab and validation by default ignore external references, but the schema tab provides options to resolve all or some external references or bundle all content within the same schema with one click. Once resolved, also the data tab and validation will take the content of the reference into account, as it is now part of the schema.
In the menu bar of the schema tab, there is a set of utility options for resolving all references or bundling a whole schema, as well as an inverse option (extract all inlined schema elements into definitions and replace them with references).
Furthermore, the schema diagram visualizes external references as nodes with a blue color frame and provides a button to resolve the reference directly in the diagram.
If (external) references can not be resolved due to cyclic dependencies, instead use the utility to bundle the references. This way all external content is moved into the same file, but the schema still uses internal references, which can model cyclic dependencies.
