Why Animated Icons Need Embedded Motion Metadata to Work Properly

Animated icons carry behavioral properties — such as triggers, duration, looping, and easing — that static metadata fields like name, size, or viewBox cannot capture. A single icon design can serve entirely different purposes depending on whether it plays once on click, loops during a pending state, or responds to keyboard focus, making those distinctions critical for correct integration. Without structured motion contracts, developers importing icons from libraries or APIs must manually reconstruct intended behavior in every implementation. Proposed metadata fields like trigger events, loop conditions, and intended duration would allow assets to communicate their design intent directly. This becomes especially important for accessibility, where animation must not be the sole means of conveying application state to users.
