Kupu Resource Types

While libraries provide abstract locations for objects of any type, Kupu distinguishes objects by resource type. For example, a user might request a library showing objects to link to or a library showing objects to be inserted into a document. The abstract location (library) might be the same, but the former library would contain documents, the latter images.

This management screen allows you to define resource types using a list of portal types. A special resource type, collection, identifies portal types that are to be treated as collections. The resource type containsanchors is used to list types which may contain HTML anchors.

Also on this screen are urls for each type which can be previewed as an image. The expression may use object_url and portal_type, but should not attempt to access the object directly. The resulting URL should ideally return an image no larger than 128 pixels square.

`Preview` is an expression to use for the preview image in the drawer [default is no preview]. `Normal image` is an expression to use for the normal view of a mediaobject [string:$object_url]. `Fieldname` is the name of the field to use for scaled variants of the mediaobject [image]. `Classes` is a list of classnames which may be selected when inserting the object as media. `Type` controls whether kupu inserts an img tag or an object tag to embed flash.
