Hi David,

1. Conceptually you need to find the objects/topics you want to change... across folders, or existing metadata filter criteria, etc...perhaps manual selection (be inspired by standard Out-GridView -Passthru)
2. Do the change in a save way (perhaps first with -WhatIf)

Some inspiration on https://github.com/RWS/ISHRemote/blob/master/Doc/ReleaseNotes-ISHRemote-0.13.md#repository-corrections

Best wishes,
Dave

Thanks for reply.

I did this but not with ISHRemote. It was a large number of DITA topics (about 1500) that needed to have various metadata fields updated. I exported the large publication and used scripts (Ant, XSLT, Python) to read the content and based on that, add certain metadata to the metadata files. Then I uploaded the changed topics and metadata files using Content Importer.
