# Interoperability `kaal:entity:interoperability` **Status.** derived This node is assembled mechanically from the 25 claims that carry the concept tag `interoperability`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself. ## Every claim under this term 25 claims across 12 works, 2018 to 2025. **2018** - [3249860-034](https://wulfkaal.github.io/claims/3249860-034) [predictive/argued] -- Layered tokens are expected to remain more popular in the future because the interoperability of tokens generally assures survivability. > The author expects the layered tokens to remain more popular in the future as the interoperability of tokens generally assures survivability.
