id	Concept description	Example	AECdeltas naming	Speckle naming	3D repo naming	BHoM naming	Other proposed namings	Notes
1	Container for the "containers" (2) (collection of collections of objects)	An entire building	Project	Project	Project (/federation?)	-
2	A series of Revisions (3), each one containing objects	A Model, representing a part of a building, or a discipline specific-view of the whole building, that changes in time and whose state is recorded in a series of Revisions (3). For example, an MEP model of the plumbing of a building that will undergo change as the project evolves can be stored in here.	Stream	(Parent) Stream		-	Container, Project
3	Given state in time of the Container (2), expressed as a collection of objects	A snapshot in time of a Model.	Revision	(Child) Stream			Version, Revision, State, Snapshot, LampPost, Checkpoint
4	Upload on the online "container" (3)		Upload			Push	POST, PUT
5	Download from the online "container" (3)		Download			Pull	GET
6	Delta: Objects added in the UI	E.g. an user creates a new object; that object will then be pushed online on the container	OnlyA			ToBeCreated	New, Created, OnlySetA, AOnly	In BHoM, the point of view for the object status is looking from the external software. E.g. Created = it's been added in the external software
7	Delta: Objects deleted from UI		OnlyB			ToDelete	Old, Deleted, OnlySetB, BOnly
8	Delta: Objects modified in UI		Modified			ToModify	Modified, Intersection-Modified
9	Delta: Objects not changed in UI		Unmodified			-	Unchanged, NotModified, Intersection-NotModified
10	User choice in front of a conflict status emerged from his upload action	User pushed some change, but server responds with an error, e.g. because the user did not pull the lastest changes in a while	Conflict resolution				Conflict resolution, Pick&Choose, Modify, Merging
11	Id of an object; this id does not change when the object changes (it's maintained between different revisions)		Persistent ID
12	Id of an object; this id changes when the object changes (it's always unique at any point in time)		Unique ID					Is it an GUID or a hash? Does not matter
13	Delta message, used to transfer the information. Should be as stripped down as possible, minimum amount of information needed						DeltaMessage, DeltaPayload,
14	Delta as result of the collection level diffing						Delta, DeltaDiff
15	Delta as result of the property level diffing		DeltaStream				DeltaStream, HistoricalDelta, DeltaHistory, DeltaTracked
