Embargo

Embargo content indefinitely or till specified date, limiting access to specific users and/or IP addresses.

This module is intended to be a successor to https://github.com/discoverygarden/embargoes

Installation

Install as usual.

Migrating from embargoes

Migrations exist in the migrate_embargoes_to_embargo module for migrating from embargoes's entities onto embargo's. See the module's docs for more info.

Configuration

Configuration options can be set at admin/config/content/embargo, including a contact email and notification message.

Embargoes can be managed at admin/content/embargo.

To add an IP range for use on embargoes, navigate to admin/content/embargo/range and click 'Add IP range'. Ranges created via this method can then be used as IP address whitelists when creating embargoes. This CIDR to IPv4 Conversion utility can be helpful in creating valid CIDR IP ranges.

search_api processor(s)

We have multiple search_api processors which attempt to constrain search results based on the effects of embargoes on the entities represented by search results, including:

• embargo_processor ("Embargo access (deprecated)")
  • Adds additional properties to the indexed rows, requiring additional index maintenance on mutation of the entities under consideration, but should theoretically work with any search_api backend
• embargo_join_process ("Embargo access, join-wise")
  • Requires Solr/Solarium-compatible index, and indexing of embargo entities in the same index as the node/media/files to be search, tracking necessary info and performing Solr joins to constrain results

Typically, only one should be used in any particular index.

Embargo Notification Block Configuration

The Embargo Notifications Block provided by this module can be placed like any other Block, and it will only be visible if there is an Embargo entity associated with the content being viewed because otherwise it has nothing to display. For general information about managing and placing Blocks, see Drupal community documentation such as Managing Blocks

There is also a "Node is Embargoed" Condition provided by this module that can be used to set Block visibility for any Blocks based on the embargoed status of the node being viewed:

• "Always trigger regardless of embargo status"
• "All embargoes on node"
• "Current embargoes on node (ignore expired)"
• "Active embargoes on node (ignore bypassed)"

If you would like the Embargo Notifications Block to stop displaying when a timed Embargo expires, you would want to set the "Node is Embargoed" block visibility condition to Current embargoes on node (ignore expired) or Active embargoes on node (ignore bypassed), depending on whether you want the block displayed for users who have access to bypass the given Embargo.

Usage

Applying an embargo

An embargo can be applied to an existing node by clicking the "Embargoes" tab on a node, or navigating to embargoes/node/{node_id}. From here, an embargo can be applied if it doesn't already exist, and existing embargoes can be modified or removed.

Known Issues/FAQ

• Embargoed items show up in search results
  • Enable one of our search_api processors to handle applying embargo restrictions.
• "Embargo access, join-wise" does not show up as an available processor
  • Ensure embargo entities are being indexed in the given index.
  • Ensure that eligible node/media/files entities are being indexed in the given index.
