I would concur with William’s explanations/assertions here. I would add one slight comment though that at a model level “Collection” or any of its subclasses reference 0 or more Elements rather

Interesting article and a good analogy. I’ll add one more caveat to Williams list below: Currently, the SPDX 2.x graphs are cyclic due to use case requirements and resultant designs (despite

I like the idea of clarifying the distinction between STIX Bundle and Document. BTW - I may be able to join the call tomorrow morning – the time zone difference isn’t as large as I thought

I think this is mostly accurate with a couple of caveats/observations: We have been very careful to not depend on ordering or creation time. The order of creation of elements has no implied meaning

The October Scientific American had a fascinating article on mathematics: https://www.scientificamerican.com/article/infinity-category-theory-offers-a-birds-eye-view-of-mathematics1/. I'm not a

Clarifying the distinction between STIX Bundle and Document is my motivation for proposing Bundle: There has been discussion of "unit of transfer" as being a justification for Document. I don't

Just catching up on this conversation (whew!). A lot of good points made, many of which I agree with. I just wanted to add a couple of points – I won’t attempt to make these inline since

Just one point for now: The tech group will need to have a discussion of a new requirement. The previous long discussion was whether to use "Document" or "Bundle" to refer to an Element that has the

Comments in line.

The drawing you emailed in September shows Collection with subclasses ContextualCollection and Document. Package/BOM/SBOM inherit from ContextualCollection, and ExternalMap is a property of Document,

Collection was created to be a superclass of both ContextualCollection and Document because they have shared traits and are both containers. SBOMs do have external maps (because they indirectly

A Collection is like a set or array containing 0 or more Elements. It can contain many Elements but can also be empty (like an empty manifest for a deadheading truck). ContextualCollection is a

Greetings SPDX tech team, Based on feedback from the SPDX community, we are moving the spdx-sbom-generator to its own GitHub organization. This allows the SPDX GitHub organization to be more

Another example to illustrate the difference between ContextualCollection and NonContextualCollection: Imagine three web resources that have nothing in common: A chapter from Leo Tolstoy's "War and

1. Is a "Collection" an object containing 1 or more "Elements"? Technically 0 or more elements. This is a base class that provides the ability to contain elements, identify root elements, and to

Bubbling this to the top of everyone's email as a follow up to this week's SPDX tech meeting (Nov 2 2021): 1. Is a "Collection" an object containing 1 or more "Elements"? 2. Is a
