AW: [rda-datafabric-ig][rda-dft][rda-collection-wg] Some thoughts on "Data Aggregations" terminology & concepts

Dear all,
the DFIG co-chairs are impressed about the intensive interactions. Due to some events and other tasks we were not yet participating in the debate. Coming event we will come up with some opinions, in particular since we also need to plan the sessions in Denver.
best
Peter

Some thoughts on "Data Aggregations" terminology & concepts

There may be useful analogy to a physical sample that is collected.
You have that object at birth with an id, but over time you can add to this
and take away from it. The original ID serves a purpose but you may need
an ID for the current state
of the object at any time there has been change.

Reagan, this is a really nice outline.
All – I am on this list, but not sure exactly why? I think I was part of the original Data Fabric IG?
In any event, I’m jumping in below, with a comment that I think is implicit in the ongoing discussion, but want to emphasize one of Reagan’s below points—about entities can change over time.
A collection—viewed as either an object or collection of object (however you like it), is also a convenient grouping, and, yes, can be marked theoretically — at a point in time, although it is not necessarily stagnant.

I realize I am not addressing all of the concerns that have been raised,
but I wonder if a way to move forward would be something like the
definition below:
A collection is a digital object which is identified by a PID and consists
of a set of digital objects with explicitly defined relationships that are
identified in explicitly defined ways.
It seems that for the machine actionability in particular, an explicit way
of identifying objects and understanding the relationship between them may

Assuming that collections can be dynamic, it occurs to me, without giving it a great deal of thought, that the general principles developed in the Dynamic Data Citation WG might answer some of the questions here.
I’ll also through in my view on Ulrich’s simple definition below as a decent starting point.

Ulrich,
U>My favorite definition for collection would actually be: A collection is
a digital object which is identified by a PID and consists of a set of
PIDs/Ids - full stop
​Simple is good but this may miss an important point which is that a
Collection has composition and a statement that it has parts (which your
have IDs for) is as important, it seems to me, to state as the IDs
themselves.

Gary:
We focus on collections that enable research collaborations. The types of entities we register into a collection include:
* sub-collections
* files
* soft links to other collections (micro-service structured objects)
* soft links to objects in external repositories (micro-service structured objects)
* database queries (micro-service invocation)
* workflows (workflow structured objects)
* sensor data streams (micro-service structured objects)
