Meeting minutes


   McCool: wording change needed for TD Issue 940

   <McCool> for example, LDS might choose to use full URLs for
   JSON-LD canonical form, which would be problematic for us

   McCool: wording change needed in Signature section (attribute
   comment about Lagally action to OAuth)

   <McCool> change "Michael Lagally will look into those points"
   to "Regarding moving the detailed OAuth2 description and
   recommendations to the security best practices document, I will
   follow up with Michael Lagally"

   McCool: change for Signature section was reconsidered: remove
   the line about the above mentioned action

   McCool: one more wording change needed for TD Issue 940

   McCool: minutes approved with the mentioned changes
