Perhaps the word you are looking for is "Rite", "Use", or "Usage".
Yes but... is the 1979 BCP a new "Rite" after adopting the Revised Common Lectionary, or after publishing Holy Women, Holy Men?
No. The 1979 BCP Rite 1 is a Rite/Usage, Rite 2 is another Rite/Usage. The lectionary, calendar, and set of votives there is a single [word-i-am-looking-for], and the Revised Common Lectionary is another, and the current Roman OF propers-plus-lectionary is another.
@MichaelDickson I saw your post above about that way of naming it. The problem is that in English, I think "Formulary" is more often used for a single named set of Propers.

Enchiridion is handy. Denzinger's reference work of conciliar and papal teaching is "Enchridion Symbolorum" (Handbook of Creeds), and the reference book of indulgences is another one.
I have recently discovered that the Gregorio project documenters use the word "occasion" to describe a specific feast day or celebration. This would still necessitate use of a word like "formulary" to describe the specific set of propers, since a single occasion would have several formularies (at a minimum, one for each rite).
