Content Enrichers

Pluggable Context

Sometimes it's useful to optimize the number of requests you send to the server. For this reason, we provide a mechanism for requesting more information on the response, simply by specifying the context you require in the request header.

For example, sometimes you need to get the children, parents or workflow tasks of a document while requesting that document. The Nuxeo Platform provides you with several content enrichers out of the box for the most common use cases, and you can contribute your own if needed.

Default Content Enrichers

Enricher	Included in Response:
`thumbnail`	Related attached file thumbnail of the current document
`preview`	Related attached file preview of the current document
`documentURL`	Document's URL
`breadcrumb`	Document breadcrumb (list of all parent documents)
`subtypes`	Array of document types that can be created under the current document
`children`	List of all children documents
`hasContent`	Boolean flag indicating whether or not current Folderish or Collection document has children or members
`hasFolderishChild`	Boolean flag indicating whether or not current document has folderish child document
`favorites`	Boolean flag indicating whether or not current document belongs to user's Favorites
`collections`	The collections to which the current document belongs
`tags`	The tags on the current document
`firstAccessibleAncestor`	The closest document's ancestor which is used to find what safe document to redirect to when deleting some.
`runningWorkflows`	Workflow instances running on the current document
`runnableWorkflows`	Workflow models that can be launched on the current document
`pendingTasks`	Pending tasks on the current document
`acls`	All related ACLs of the current document
`permissions`	Current user's permissions on the current document
`publications`	Publication count of the current document
`userVisiblePermissions`	List of permissions available on current document
`audit`	Latest log entries related to the current document
`subscribedNotifications`	Current user's subscribed notifications for the current document
`userprofile`	DOB, phone number and avatar of current user

How To Call a Content Enricher

Content enrichers can be called by sending the proper header(s) in your request. The header you need to call depends on the entity-type being affected by the enricher. Enrichers on documents can be called using the header:

enrichers.document: enricherName

If you want to call an enricher on a user, you would do it through a slightly different header:

enrichers.user: enricherName

Several enrichers can be called in a single request by specifying a comma separated list in the header, or by sending several headers:

enrichers.document: enricher1,enricher2,enricher3

is equivalent to sending:

enrichers.document: enricher1
enrichers.document: enricher2
enrichers.document: enricher3

The enrichers can be called the same way by passing GET parameters.

Contributing Your Own Content Enricher

You can add your own content enricher by providing a Java class and a XML contribution. You can enrich a Nuxeo Document Model or any kind of specific object returned.

Document Model Content Enricher

Here is a sample to get you started. It provides a document's parent ID, title and description.
