David Radley commented on ATLAS-1098:
-------------------------------------

Hello,
I have just seen the commit going through for this. It looks like a tag of isa, 
clashed with a keyword in Gremlin and the fix was to police out these keywords. 
My feeling is that there should be no restrictions to tag names. If we want 
Atlas to be a widely used metadata server, I do not think it should have 
restrictions on the use of any metadata values (which I guess we would need to 
document) , based on restrictions passed through from the implementation. 
Without any restrictions metadata can be modelled intuitively without needing 
to be aware  and needing to compensate for the "quirks" of Atlas.  
                  all the best, David.
