Subject: InformationSource

While I understand the great flexibility that can exist with using a relationship object to tie a source to a TLO, I really question if the extra complexity is worth it.  

In an effort to target the 80% and to make STIX super easy to use, I am wondering if it would not be better for 2.0 to just use an optional created_by_id that points to some InformationSource Object.  In doing this I can see a lot of these InformationSource objects becoming "well known".

Then in some future release, if the community and tools need more flexibility, we could again look at using relationships.  But lets learn to walk before we try to run. Further, we have a tendency to flirt with the slipper slope of scope creep.  Lets focus on the minimum amount of things that actually need to be done to meet an 80% target.  We can always rev the standard and add stuff later.
