___REQUIRES_GATEWAY_PR___="116"

Description

This PR adds external source and event attribute validation to AERIE.

It is explained more in depth here.

The main updates to the UI for this PR surround the displaying of source and event attributes in the UI, namely in the External Source Manager, as well as an external source/event type creation page (previously Modals). Derivation group creation has presently been moved out of a modal and is delegated to the Derivation Group field where sources are uploaded.

Below is a view of the new 'External Types Manager' with an External Source Type's attribute schema being shown:

Walkthrough

Upload

To use this feature, navigate to the External Sources page of Aerie

Select the Types button in the top-right to switch to the /types sub-page.

Click the 'Choose File' button and select a complete External Source & Event type schema (see bottom of this section for an example file). The pane should display the External Source & Event types that will be created once the 'Upload' button has been clicked - click the 'Upload' button to submit & create the types.

After the types have been created, a source can be uploaded by clicking the Sources button in the top-right, then selecting the Choose File button in the left-pane, selecting the related External Source, and clicking Upload.

Viewing Schemas

The attribute schema for an uploaded External Event or Source Type can be viewed by navigating to the External Sources page and selecting the Types button in the top-right to switch to the /types sub-page.

Once on the Types page, select the tab for the desired type (Event or Source) and then hover the row containing the desired type. Click the View button that appears. On the left-pane, the type should be displayed with two collapsible categories for Attribute Schema - Definition and Attribute Schema - Properties. Definition contains any top-level fields included other than Properties, which is shown under the other collapse.

Viewing Attributes

The attributes of a given External Source or Event can be seen by navigating to the External Sources page, hovering over the row for the desired External Source, and clicking the View button. In the Selected External Source pane on the left, there is a section for Attributes which when clicked will show the specific attributes for the given source.
