temporal:axis-create

temporal:axis-create(
   $axis-name as xs:string,
   $start-range-index as cts:reference,
   $end-range-index as cts:reference
) as xs:unsignedLong

Summary

This function constructs an axis definition based on the existing range indexes that can be added to a temporal collection in subsequent API calls. The axis definition is stored in the schema database.

For details on how to create an axis, see Create System and Valid Axes in the Temporal Developer's Guide

A TEMPORAL-NONDATETIME exception is thrown if range index scalar type is not dateTime. A TEMPORAL-DUPAXIS exception is thrown if the axis already exists.

Parameters
axis-name The name to be used to identify the axis.
start-range-index A reference to a range index to be used as the start of the time period.
end-range-index A reference to a range index to be used as the end of the time period.

Example

xquery version "1.0-ml"; 
 
import module namespace temporal = "http://marklogic.com/xdmp/temporal" 
      at "/MarkLogic/temporal.xqy";

temporal:axis-remove("system"),
temporal:axis-remove("valid"),
temporal:axis-create(
   "system",
   cts:element-reference(xs:QName("systemStart")),
   cts:element-reference(xs:QName("systemEnd"))),
temporal:axis-create(
   "valid",
   cts:element-reference(xs:QName("validStart")),
   cts:element-reference(xs:QName("validEnd")))

   (: 
      First removes, then creates two axes, named "system" and "valid",
      from the element range indexes, "systemStart", "systemEnd",
      "validStart", and "validEnd".  Then it returns the IDs of the
      new axes.
