DEMP Specification version 0.4.0 is now available.
This release focuses on clarification and robustness, introducing a mandatory deterministic fallback procedure for tie-breaking, refining the normative definition of alerts and increasing flexibility in network deployment by making Internet reachability optional.
Version 0.4.0 also formally designates the Markdown (MD) file as the canonical source for all future versions of the specification, ensuring a single authoritative reference.
Minor editorial refinements were made throughout the document with no normative impact.

The Mobility of Physical Zones, introduced in version 0.3.0 of the Decentralized Emergency Management Protocol Specification (DEMP-SPEC), extends DEMP’s spatial model to support dynamic and moving safety zones. This update allows Safety Information Systems (SIS) to track, manage, and coordinate safety operations in areas whose spatial references change over time — such as vehicles, vessels, aircraft, or mobile rescue perimeters.
Until now, Safety Zones in DEMP were typically defined as static physical areas, such as buildings, campuses, or geographic sites.
With the addition of mobility in DEMP-SPEC 0.3.0, Physical Zones can now be classified as either:
Static — fixed in position, defined by constant spatial references (e.g. a building).
Dynamic — moving or evolving zones whose position changes with time (e.g., a vehicle or rescue area).
By introducing Mobility of Physical Zones, Safety Information Systems are now capable of managing both fixed and moving environments — a step toward a fully adaptive and spatially aware emergency management ecosystem.
Zone Mobility extends DEMP’s spatial model beyond fixed locations, enabling Safety Information Systems (SIS) to operate seamlessly across moving and adaptive environments.
Transports: Dynamic zones for vehicles, vessels, trains, and aircraft allow continuous situational awareness and real-time coordination while in motion.
Disaster Response: Evolving rescue perimeters adapt to changing terrain and operational conditions during emergencies.
Industrial Sites: Dynamic zones support mobile worksites and large-scale construction operations in constant movement.

The Ad Hoc Network introduced in DEMP 0.2.0 enables decentralized, mesh and peer-to-peer communication between Safety Information Systems (SIS) and devices, ensuring alerts and coordination continue even without Internet connectivity.
The introduction of the Ad Hoc Network capability in version 0.2.0 of the Decentralized Emergency Management Protocol Specification (DEMP-SPEC) extends DEMP’s flexibility by allowing Safety Information Systems (SIS) to operate even when Internet or local connectivity is unavailable.
An Ad Hoc Network is a local, decentralized communication environment formed dynamically by the devices that participate in it. Instead of relying on a local or Internet link, each node can connect directly to others nearby, creating a temporary mesh or peer-to-peer network capable of forwarding information securely across multiple hops.
In the context of DEMP, this means that alerts and safety information can still propagate between participating Entities during network outages or in isolated areas.
The Ad Hoc Network section defines that a Safety Information System (SIS) may operate in mesh or peer-to-peer mode to exchange DEMP messages. Messages are transmitted over any compatible communication protocol that supports secure, multi-hop, or direct propagation.
Each participating SIS or entity authenticates locally and continues to apply DEMP’s cryptographic trust model, ensuring that even offline exchanges remain verifiable and tamper-resistant.
For the technical definition of Ad Hoc Network support, see:
The Ad Hoc Network capability reinforces DEMP’s vision of a fully decentralized, resilient emergency communication ecosystem—capable of operating anywhere, anytime, even beyond the reach of the Internet.
DEMP: decentralized, secure, and adaptive by design.
Version 0.2.0 of the Decentralized Emergency Management Protocol Specification (DEMP-SPEC) introduces two major improvements that strengthen the flexibility and accessibility of the specification.
This release adds support for Ad Hoc Network operations and establishes a stable web path for referencing the latest version of the specification. Together, these changes enhance both the practical resilience of DEMP implementations and the long-term reliability of its documentation.
