I generally support this proposal.
I agree with Chelsea's observation and have the following additional comment:
Recommendation 3: Create a new element, Manifestation: duration of embodied content. Add Manifestation: duration of embodied content as a subtype of Manifestation: extent of embodied content.
Comment: Generally agree - but where is the text of the instructions? This proposal stops after the definition & Prerecording section. For suggested new elements, I expected to see the full text, even if it is as brief as note on collective agent. To fully understand how all of these proposals interrelate, the full context would be helpful.

Only one minor editorial comment and that is that "notated music" is listed twice in the scope note in Recommendation 3. (I think one of those "notated musics" is supposed to be a "notated movement".) But otherwise I support this proposal and think the proposed recommendations provide much needed clarification for recording duration.

This approach seems reasonable for both catalogers and users to me.

Below is the abstract for this proposal. Please see the attached for the full proposal and comment no later than Monday, December, 22, 2025.
Abstract
This proposal paper recommends changing the current condition options for Expression: duration to exclude the option to record the total duration of aggregating expressions. It also includes a proposal to remove a condition and options for Work: duration of representative expression element, and a proposal for a new element for Manifestation: duration of embodied content that would record the duration of embodied content for manifestations with embodied content in temporal form (including performed music, sounds, spoken word, two-dimensional and three-dimensional moving images, and performed movement) or embodied content with an envisioned temporal duration (including notated music and notated movement).
