doc-count-udf

A MarkLogic User Defined aggregation Function for accumulating elem/attr frequencies per uri

Compile

Run make on the appropriate target (or equivalent) system. You cannot compile on MacOS and run on CentOS for instance!

Install

Run the following in QConsole (database not important):

xquery version "1.0-ml";

import module namespace plugin = "http://marklogic.com/extension/plugin"
  at "MarkLogic/plugin/plugin.xqy";

plugin:install-from-zip("grtjn",
  xdmp:document-get("/path/to/grtjn/doc-count-udf/doc-count.zip")/node())

Use

For example:

cts:aggregate(
  "grtjn/doc-count", 
  "doc-count", 
  (
    cts:uri-reference(),
    cts:element-attribute-reference(xs:QName("file"), xs:QName("size"))
  )
)

This function returns a map:map with uri as keys, and sum of frequencies per uri as values.
