   $docs-descriptors as map:map+,

) as map:map

Summary

This function constructs document rows from the docsDescriptors.

Parameters
$docs-descriptors A map of document descriptors. Each document descriptor describes a document. A document descriptor contains a combination of uri, doc, collections, metadata, permissions, quality and temporalCollection. This is a simpler form of op:from-param.
