es:instance-converter-generate

es:instance-converter-generate(
   $model as map:map
) as document-node()

Summary

This function is deprecated and will be removed in a future release.
Generate an XQuery library module containing stub code for converting source data to entity instances.

Parameters
model A valid basic entity model.

Usage Notes

The output of this function is an XQuery library module containing boilerplate code you can customize for ingestion scenarios. You must insert the generated module into your modules database to use it.

The generated module contains code to get you started on a data integration pipeline. The module also contains comments that explain the default code and provide tips for customization.

The generated code is runnable out-of-the-box, but the default implementation is suitable for only those entity instances that already conform to the canonical representation. Any transform from source systems should be implemented by customizing the generated functions.
