At Open RV 27db5464 the OTIO reader imports markers (name, range, colour, metadata as JSON) and turns OTIO annotation layers into RVPaint strokes placed on each layer's end-inclusive frame, with hold/ghost as session settings; the writer exports markers only when the importer-created otio_metadata property exists and has no annotation/paint code, so drawn notes are import-only and RV-native markers may not export (inference from the guard). No Marker.comment is carried either way.
