Description

Background

Sling Pipes modify content without leaving a trace in the repository. Developers should have the ability to mark resources modified by the Sling Pipe. While modifying the resource, the 'Write' Sling pipe could also set metadata info indicating the time of modification and the author of the change.
Example: pipe 'enable-foo' sets the property foo=true on nodeA.
without metadata:
nodeA
    foo=true

with metadata:
nodeA
    foo = true
    jcr:lastModified = 2021-08-09T11:06:56.753+02:00
    jcr:lastModifiedBy = sling-pipe-enable-foo

 

Suggestion

To add a 'metadata' flag to content modification pipes. When set to true, the pipe will set 2 properties on each modified resource:

•  'jcr:lastModified' - current server's DateTime.
• 'jcr:lastModifiedBy' - 'sling-pipe-${pipe_name}'

By default, the metadata flag is set to false and will do nothing.

Q1. should we make 'jcr:lastModifiedBy' - 'sling-pipe-${pipe_name} on behalf of ${user}'?
Q2. what other pipes to adapt
