[oslc-core] Core WG topic: Attachments and non-RDF resources

[James Conallen]

I think there are a couple of points related to attachment lifecycle that
Nick had mentioned that are critical to the definition of an attachment
that could be added to this document.

1. Attachments are deleted when the referencing resource is deleted.
Attachments can be explicitly deleted without deleting the referencing
resource.
2. Attachments should (must?) be owned an managed by the same provider that
manages the resource that references it.

We had a good discussion of the topics of Attachments and Non-RDF
Resources. I think that some were confused because I was conflating
the two topics and covered many approaches, including an overly
complex one, but I think it was useful to discuss both topics
together.

To follow up, I have written a page that focuses on Attachments only.
Here's what I believe are the three important use cases for
attachments and a simple pattern for each:

I think we want all domains to handle attachments in a consistent way,
so perhaps we should work to create a guidance document? Other ideas?

As always, feedback is most welcome.

Thanks,
- Dave
