NOTAMuri

NOTAMuri is a proposed concept for encoding and dereferencing NOTAM data using Uniform Resource Identifiers (URIs) to enable stable, machine-readable references to NOTAMs across systems. It is not an official ICAO standard, but a community-driven approach intended to improve interoperability among NOTAM publication systems, flight planning tools, and air traffic management.

The core idea is to assign a persistent URI to each NOTAM, allowing clients to retrieve the current or historical record via standard web protocols. A NOTAMuri typically points to metadata about a NOTAM, such as issue and validity times, geographic area, subject, severity, and issuer. Underlying data may be delivered in machine-readable formats such as JSON or XML, often via an API or a dereferenceable web resource. Implementations may use registries, versioning, and dereferencing rules to preserve stability even when content changes.

Potential benefits include easier linking in digital workflows, improved aggregation of NOTAM data across providers, and more robust archiving. Limitations include lack of universal adoption, potential privacy or operational sensitivity concerns, and the need for governance to prevent dead or ambiguous URIs.

In aviation data discussions from the 2020s, NOTAMuri has appeared in pilot projects as a possible enabler of better interoperability. No formal standard has emerged, and adoption varies by provider and jurisdiction.
