Architecture Subdomains
#######################

Currently, these are the `architecture subdomains`_ used by the Open edX Filters library:

+-------------------+----------------------------------------------------------------------------------------------------+
| Subdomain Name    | Description                                                                                        |
+===================+====================================================================================================+
| Content Authoring | Allows educators to create, modify, package, annotate (tag), and share learning content.           |
+-------------------+----------------------------------------------------------------------------------------------------+
| Learning          | Allows learners to consume content and perform actions in a learning activity on the platform.     |
+-------------------+----------------------------------------------------------------------------------------------------+

Here we list useful information about Open edX architecture subdomains and their use in the Hooks Extension framework:
