An initiative providing open infrastructure for collaborative annotation of stimuli used in neuroscience research. Uses git branches as stackable annotation layers, BIDS/HED standards for interoperability, and AI-accelerated annotation generation with human refinement. Directly relevant to ReproStim-captured audio/video stimuli and generalizable to any experiment with media needing temporal annotation.
