Viewing Resources

The UI defines different types of pages to display various resource information:

  • Facepage: The primary overview page used for viewing resource information and related resource information.
  • Command page: Used to interact with resources that can be commanded such as instruments and platforms

See CIAD UX UI Facepages for a list of UI facepages by resource type with content expectations.

Create and Edit of Resources

The Web UI provides a page to edit resource metadata and associations to other resources. The figure below shows the interactions with the OOINet backends during creation and edit of a resource.

Implementation Details


The Web UI Framework is based on a Python Flask extension to an Apache server. It provides the security session management and delegates to CIlogon for authentication.

The browser side UI has abilities to dynamically compose screens based on view and resource type and fill fields with resource attribute values.

Source Code Location

The source code for OOICI UI can be found in the "ion-ux" repository on Github (
