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.

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 may0 | Add new comment

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.

Dear Jeremy, Jeff, Gary, You are right, that the purpose of the collection definition of the collection WG is to set a minimum bar to get as much specificity as necessary in order to outline an API at the end, that is able to handle specific queries on collections. The question whether DOs might be identified by a formal ID, or by a query, or by some other method, is currently not really solved in this context, and the idea to construct a collection by some function is rather new in the collection WG.0 | Add new comment

If I am following correctly (and please disregard if not) a key question to formulating the definition is how digital objects are identified (and whether they have to be). That is, they might be identified by a formal ID, or by a query, or by some other method (including that someone might say a collection of bits--which themselves might have no identifying features, though they could collectively be described--make up the collection or entity they are interested in understanding as a collected whole).0 | Add new comment

Re: [rda-datafabric-ig][rda-collection-wg] Some thoughts on "Data Aggregations" terminology & concepts
Keith, In short I think the answer is yes, that collections such as generated by queries can be parts of DO collections. I would go back to Reagan Moore's early observation (to effect if I understand right) that " "Digital collections implement arrangement by a community for organizing their digital entities.." They are then aggregations of interest defined by communities. Now this ultra flexibility may, I have a sense of worry without having figured this out, overload the role of digital object since it seems to0 | Add new comment

I was also thinking along the lines of Jacob's suggestions, but hadn't gotten as far. >Rather than define the collection as multiple sets (one of identifiers, one of links, and one of metadata), why not just define it as a set of digital objects (each of which has an identifier, some link pointing to it, I was also thinking along the lines of Jacob's suggestions, but hadn't gotten as far. >Rather than define the collection as multiple sets (one of identifiers, one of links, and one of metadata), why not just define it as a set of0 | Add new comment

Re: [rda-datafabric-ig][rda-collection-wg] Some thoughts on "Data Aggregations" terminology & concepts
Dear all, since this discussion gets a bit less agile in the last days, it is perhaps a good point in time to reflect the outcome of this discussion in the definition I proposed. I think we identified the mayor problems in this preliminary definition. The suggestion I give to avoids these problems essentially goes along the lines, Jakob made some Emails earlier (12.4.): "... A better definition might be: A collection is a digital object which consists of a set or a list and is named by a PID (which when0 | Add new comment
