Description

The JSON Renderer in the Sling GET Servlet does not export binary properties and prints the length instead of the data:

{
  "jcr:primaryType": "nt:resource",
  ":jcr:data": 20127
}

Note that the names of binary properties are prefixed with a colon.

I would like to introduce an OSGi flag to enable exporting binaries in base64. If enabled, the output would look something like

{
  "jcr:primaryType": "nt:resource",
  ":jcr:data": "iVBORw0KGgoA...."
}

The default is false which means existing consumers will keep getting the length.

There is a related ticket https://issues.apache.org/jira/browse/SLING-11891 to make sense of the base64 data when importing from JSON.

This change will improve symmetry between export and import in Sling GET/POST servlets and make round-trips more reliable.
