What relationship should excerpt recordings copy from its parent recordings?

I am editing this release, it’s basically a large single 3-hours recording that was released in different forms and splitted in different ways due to the length:

  • CD: 77mins excerpt from 2hrs 42 mins
  • 3LP: full recording splitted into 6 sides
  • 3CD-R: full recording splitted into 3 parts
    I am planning to structure the recordings this way:
Work
↓     ↓
↓  Event 
↓     ↓
Full recording (standalone recording) [2:42:32] 
- (has edit) CD recording [77:00]
- (has edit) CDr recording 1 [54:00]
  - (has edit) LP recording 1A [26:59]
  - (has edit) LP recording 1B [26:59]
- (has edit) CDr recording 2 [54:00]
  - (has edit) LP recording 2A [26:58]
  - (has edit) LP recording 2B [26:57]
- (has edit) CDr recording 3 [54:32]
  - (has edit) LP recording 3A [26:59]
  - (has edit) LP recording 3B [27:59]

I think this should represent the editing relationship relatively accurate. (The reason I put the LP per-side recordings as edit of the CDr recordings is the label mentioned that the CDrs feature the “complete digital mastering” used in the LP, so what I understand is that the 3 CDr recordings are in fact the same recordings of the 3 LPs, but been splitted further each into 2 sides due to the LP capacity.) There are some messy edits in the releases because I did not know about the standalone recording when I initially add the releases.

The question is, I now added all relative relationship (performer, recording of (work), etc.) to the Full recording with no problem, but I am not sure what relationship I should copy to the excerpted recordings. Like should I have all performer relationships in all of above recordings? Or should I not copy any of them to avoid redundancy (since there were only one “recording” happened) but just have the additional ones (edit of, editor, etc.) in the excerpt recordings?

In the two examples in the documentation none of the relationships but (recording of [work]) and (music videos) are inherited from the parent recordings to the edit ones. I could not find a related guideline though.

Personally I think either way makes some sense, just want to make sure if there’s any rule or common practice that I am missing.

I generally copy all (or all that apply, in cases where a performer is in the full recording but not the excerpt, for example)

i don’t know exactly if it is appropriate to use when dealing with excerpts, but the other recording-recording relationship you may consider instead is the “compilation of / compiled in” relationship, which would allow you to order the sequence of the excerpts linked to the complete recording.

Thanks! I was thinking of using the compilation relationship but was a bit hesitate in this case, I think the main issue is the division of this recording is not based on actual songs (like in the documentation description “one long recording that contains multiple songs”) but rather arbitrarily based on the length. In the “multiple songs” situation one sequence is usually enough because there are fixed number of songs in a recording, so simply put them in order should be enough. But in this kind of arbitrary split there could be multiple sequences (like in my case it has been splitted into 1 (shortened), 3, and 6 tracks which sequenced their own, and new release could just split it in a different way anytime, I’m sure there are other examples) which seems not easy to deal with one sequence of order numbers.
