Palantir and Allied Interoperability

Interoperability in coalition operations is almost never a technical failure. The protocols exist, the standards exist, and competent engineers can connect most things to most things given a fortnight. What stops information moving is that one nation is not permitted to give another nation the material in question, and no amount of middleware resolves that.

This is why interoperability projects that begin with data formats tend to disappoint, and why the ones that begin with release policy tend to deliver. The useful question is not how to share everything, it is how to share the minimum that allows a partner to act.

Separating product from source material

The most valuable architectural decision in coalition working is keeping an assessment separable from the material behind it. A partner can then receive a judgement, with its confidence and reasoning, without receiving the protected source that informed it. They can see that a conclusion rests on corroborated material without being handed the corroboration.

Doing this properly requires the model to treat product, evidence and source as distinct linked objects, each with its own handling marking. Systems that store an assessment as a document with its sources pasted in cannot support selective release, which is why so much coalition sharing still happens by email with a human deciding what to redact.

Caveats have to travel with the data

Handling instructions written in a covering email are lost the moment the attachment is forwarded. Markings carried as properties of the object itself survive, and can be enforced by whatever system the recipient uses, provided both parties agree on what the markings mean.

That agreement is the genuinely hard part. Classification schemes differ between nations, and the mapping between them is imperfect and politically sensitive. Any serious coalition deployment spends more effort on reconciling markings than on connecting systems, and programmes that budget the reverse run into trouble late.

Who releases, and on what authority

Deliberate release means a named officer, a recorded justification, a defined recipient group and a retrievable record of the decision. It is slower than open federation and it is the only model that survives review. The platform’s job is to make it fast enough to be used under pressure rather than circumvented.

If the governed route takes an hour and the informal route takes a minute, people will use the informal route and the audit trail will be fiction. Usability is therefore a security property, not a nicety, and this is the single most common place where well-designed coalition sharing schemes fail in practice.

Neutral ground, and the dependency it creates

Commercial platforms have been useful in NATO and EU settings partly because they are nobody’s national system. A shared commercial environment is easier to agree on than one nation’s infrastructure, which is a political advantage rather than a technical one.

The cost is a shared dependency on a single supplier across an alliance, which several European governments have identified as a strategic concern. The sensible mitigation is at the model layer: if the ontology, the data and the release logic are owned by the alliance and documented, the platform underneath is replaceable at a cost that is painful rather than prohibitive.

What to do before the exercise

Coalition information sharing is almost always tested for the first time during a real operation or a major exercise, which is the worst moment to discover that two nations disagree about what a marking means. Agreeing the object model, the marking mapping and the release workflow in advance is dull preparatory work with a very high return.

AIC designs and facilitates scenario work of exactly this kind, and builds the release and governance layers that make it workable. Our PAL.NET SDK gives .NET teams typed access to Foundry and their own ontology where that is the platform in use.
