What is the best way to model document references?

[mse]

I am importing PDFs, word document or other files into the model so that I can track the references we are using. I want to generate a report with a table listing like this:

Reference	Summary	Version	Title
Ref. [1]	SysML Standard	1.7	OMG Systems Modeling Language (OMG SysML™)
Ref. [2]	DO-178	C	Software Considerations in Airborne Systems and Equipment Certification

It seems I can do this in many ways. I could go with Artifact, and give it a name (for the summary column), alias (for the "Ref. x" column), notes for the title column, and version using the Version column.

I am using Artifact option because when I drag and drop a PDF onto a diagram, I am presented with Artifact (internal) or Artifact (external) in a context menu. This seems to work, and I can also generate a report, but is there a better way? The only reason I ask is because of that first column Reference. I have to use the Alias field of the element, but I'm not sure if that's the proper use of Alias, even though it could be anything.

I would also like to reference the artifact from other Notes fields. This may be stretching EAs capabilities a bit, but I want to see the reference text update in the notes if [Ref. 1] for example is deleted or changes (just like maintaining a list of citations in academic papers).

When using references like this, I tend to keep away from numbers.
For the list you present I would use e.g.:
Reference
[SysML] ....
[DO-178] ...

The advantage is that you don't have to wonder how to renumber when a reference is removed (or not used).
And I think it would be easier to keep the references unique.
Lastly, you can always use the correct reference in the text when referring to a document as it is not likely that a reference will change once it has been defined.

One last remark, you probably would even be able to sort the list of references based on the name of the reference.
