Rights management for assets

These rights affect the manipulation and visibility of asset values for user-defined objects. The realms for assets are the same realms that apply for objects. In general, the rights management for assets works the same as for objects.

Asset versions can be subject to rights management or not (see EAS rights management configuration). The rights asset_show and asset_download refer only to the rights managed versions (the other ones are always visible).

Asset rights can be filtered. In all cases, an empty attribute means “do not filter”:

column_ids: which columns are affected by the right; if this parameter does not exist or its value is an empty array, all columns are allowed
limit: limit (in bytes) for an upload
classes: allowed file classes for an upload: if a class is allowed, uploading files of the class is allowed regardless of their extension
extensions: allowed file extensions for an upload

The versions have a hierarchy, defined by their order in the settings file.
