Hi all,

This is redirected from the Matterhorn-Users list...

Is it "safer" to place the Archive workflow operation before all distribution operations? Is that the same as omitted distributed source-tag in the archive operation's source-tags configuration?

  ref: http://opencast.jira.com/wiki/display/MH/The+Episode+Service
|<||operation| |id||=||"archive"|
|||fail-on-error||=||"true"|
|||exception-handler-workflow||=||"error"|
|||description||=||"Archived"||>|
|||<||configurations||>|
|||<||configuration| |key||=||"source-tags"||>engage,-publish</||configuration||>|
|||</||configurations||>|
|</||operation||>|

If information about distributed media is omitted from Archive, can media still be retracted from distribution channels?

MH-9237, "Episode Service fails making archive of media package after distribution to YouTube" http://opencast.jira.com/browse/MH-9237
has a nearly identical stack trace to
MH-9172, "archive operation fails with null pointer exception after streaming distribution" http://opencast.jira.com/browse/MH-9172 We thought MH-9172 was because the stream media is RTMP. Is it possible that this was because the RTMP link did not end with a file extension?

Thanks!
Karen

Hi All,

I recall a Matterhorn expert saying that the Archive step must occur prior to steps that change resource paths in the mediapackage. But I cannot recall where this was stated. Is there general guidance on which steps the Archive step should precede in a workflow?

Our Archive step occurs just before Distribute-Streaming, per ticket http://opencast.jira.com/browse/MH-9172, and after Distribute-Download. We tried to apply a zip operation on an Episode (from 1.4rc2) but significant files are not found within our current Archive.

Also, I notice Archive is placed after Distribute-Streaming in opencast wiki http://opencast.jira.com/wiki/display/MHDOC/Archived+Workflows.

Thank you,
Karen
