URL Namespacing

[clemiller]

As a user of Workbench, I want to be able to configure a namespace for URLs:

• ATT&CK ID URLs. The ATT&CK ID object in the list of external references contains a URL that is currently hardcoded to attack.mitre.org. I would like to be able to configure this URL.
• LinkById tags. LinkById tags are parsed into a markdown link formatted as [Object Name](https://attack.mitre.org/type/object_id) when exporting objects & collections. I would like to be able to configure the URL for this markdown link, rather than use the hardcoded attack.mitre.org URL.
  • The specified URL should be used to convert LinkById tags to markdown links. For example, if the admin configures https://example.com/ as the URL, LinkById tags should be converted to [Object Name](https://example.com/type/object_id)
• The admin should be able to define an ATT&CK ID URL and/or LinkById URL on the organization settings page. If no URL is specified, default to attack.mitre.org
