ConfigurablePublishWorkflowOperationHandler

Description

The ConfigurablePublishWorkflowOperationHandler will distribute the given elements and create a publication element for it. By default it will retract all publications before publishing anew.

Parameter Table

These are the keys that are configured through the workflow definition. At least one media package element must match the supplied source-flavors or source-tags or else the operation will not know what to publish. The channel-id and url-pattern are also mandatory.

Key	Description	Example	Default
channel-id	Id of the channel to publish to	internal
mimetype	Mime type of the published element	text/html	Type of last distributed element
source-flavors	Flavors of the media package elements to publish	*/trimmed
source-tags	Tags of the media package elements to publish	engage
url-pattern	Pattern to create the URI for the published from	ftp://…/${event_id}
with-published-elements	Use the current contents of the media package instead of publishing elements to a channel	true
check-availability	Check if the media is reachable after publication	false	false
strategy	Strategy for when there is already published material	fail	retract
mode	How elements are distributed	mixed	bulk

Mode

The configuration key mode can be used to control how media package elements are being distributed:

Mode	Description
single	For each media package element, a job is created
mixed	One job for all media package elements that are not tracks and one job per track
bulk	One job for all media package elements

This allows you to choose a lot of jobs and parallelism (single), just one job and no parallelism (bulk) or something in between (mixed). The best choice depends on your setup.

URL Pattern Variables

These are the variables available in the url-pattern configuration. They will be replaced with the value during the execution of the workflow operation.

Variable	Description	Example
${element_uri}	URI of the last media package element	http://ex.com/files/mediap...xy.mp4
${event_id}	The event (media package) identifier	18633e04-1a3f-4bbb-a72a-99c15deba1b9
${player_path}	The player path for the event	/engage/theodul/ui/core.html?id=
${publication_id}	The id of this publication.	54f6c12d-8e68-4ec8-badf-cd045b33d01e
${series_id}	The id of the series if available	36f3c5d8-ad4d-4dab-beb1-1400ffab4a69

Publication Channel Labels and Icons

Using this workflow operation, you can create arbitrary custom publication channels. Without further action, the administrative user interface will label these channels "Custom". You can specify both a label and an icon for each custom publication channels in the configuration files etc/listproviders/publication.channel.labels.properties and etc/listproviders/publication.channel.icons.properties.
