The RV reference manual documents pen and text component properties (width, gauss/circle brush, normalised points, join, cap, over/erase mode, start frame and duration; text position, colour, spacing) under names pen:id:frame:user; the interactive Mu mode actually appends the user and a process id, and Python/OTIO writers use the literal 'annotation' (CA-AM-0040). The node code also handles rect, ellipse, arrow and line components not listed in the table (producer reading).
