Aliases, Tags, and WikiLinks... Where have I gone wrong?

I think you’re overcomplicating things and trying to use WikiLinks and aliases in ways they’re not intended.

With aliases, you should not have multiple files with the same alias. Adding an alias of NASA to a document named National Aeronautics and Space Administration would make sense and be an appropriate use of an alias.
.
WikiLinks aren’t for creating context. They just link to an item, typically a document. If you had a document named Edwin Hubble, with info about him and his work, WikiLinking to that document would make sense.

Why aren’t you just tagging their documents with their names?
