I am developing a timetabling application. We invite constraints/preferences from teachers on what hours they can teach. Constraints can be invited for time slots as
- Exactly-identified slots- the teacher checks specific hours from a work-week ("...hour 2 on Friday")
- Abstractly-identified slots- not specific to any particular hour ("...in the same day")
A constraint is composed of [preference]-[identified slots] such as
- [prefer not to take] [4 slots a day]
- [must take] [hour 2 on friday]
What are good terms for exactly-identified slots and abstractly-identified slots? I prefer (one-word) nouns as they are already described by adjectives.
