title: UTM API (USS->DSS and USS->USS)
version: 0.3.15
description: |-
Interface definitions for 'Discovery and Synchronization Service' (DSS) and 'UAS Service Supplier (USS).
DSS functionality includes identification of peer UTM USS instances (managing flight operational intents and constraints).
USS functionality includes sharing details of flight operational intents and constraints.
Note: Unless otherwise specified, fields specified in a message but not declared in the API shall be ignored.
Whenever a object-type field may be omitted, it may also be set to null for the same effect.

Client may manage (create, edit, and delete) constraints they manage.

Client may read constraint references from the DSS and details from the partner USSs.

Client may set the availability state of USSs in the DSS.
description: |-
Authorization from, or on behalf of, an authorization authority. This authority shall issue access tokens that are JSON Web Tokens as defined in RFC 7519, using the `RS256` algorithm for the signature, publish to all providers the public key for verifying that signature, and implement standard OAuth server discovery mechanisms as described in RFC 8414.
The following fields shall be included in the JWT claim for access tokens issued by this authority:
* `iss`, with the URL at which the token generation request was received.
* `exp`, with a time no further than 1 hour in the future.
* `sub`, with unique ID of the client requesting the access token.
* `scope`, with a string composed of a space-separated list of strings indicating the scopes granted, per RFC 6749.
* `jti`, according to RFC 7519.
Following the principle of least privilege, only one of the scopes enumerated in this document shall be granted in a single token (though other scopes may accompany it). The tokens granted by this authority shall protect against reuse of received tokens to impersonate the sender to other recipients (via use of the `aud` claim or other means).
When using the `aud` claim to protect against the reuse of received tokens, and absent guidance on behalf of the competent authority to the contrary, the JWT `aud` claim requested by the client shall be included in each access token and shall contain the fully qualified domain name of the URL the access token will be used to access. For example, if a USS were querying the endpoint at https://dss.example.com:8888/rid/v2/dss/identification_service_areas, the access token included in the request should specify `"aud": "dss.example.com"`.
Clients shall provide these access tokens in an `Authorization` header in the form `Bearer <token>` in accordance with RFC 6750.

EntityOVN:
title: EntityOVN
description: |-
A token associated with a particular UTM Entity+version created
by the DSS upon creation or modification of an Entity reference and provided
to the client creating or modifying the Entity reference. The EntityOVN
is stored privately by the DSS and then compared against entries in a Key
provided to mutate the airspace. The EntityOVN is also provided by
the client whenever that client transmits the full information of the Entity
(either via GET, or via a subscription notification).

Key:
description: |
Proof that a client has obtained the latest airspace content, used to ensure that write
operations to the DSS occur only when the latest content is known (i.e. has been read). The
client is required to pass a current Key constructed from information obtained with
previous read operations and subsequent requests for full information, and optionally,
subscription updates for deconflicted write operations to the DSS. The contents of this
data structure are generated by the client.

The create or update request for this operational intent reference must include a Key containing all OVNs for

In this state, the `/uss/v1/operational_intents/{entityid}/telemetry' USS-USS endpoint should respond, if
available, to queries from USS peers. The create or update request for this operational intent may omit a Key
