2.7.3 Map Definitions

 
ForeignKey (MapTypes) map map
A map meme which indicates that its meme can be used as a foreign key into another table. The foreign occurrence of the meme is indicated by the isa_mid.

 

Identity (MapTypes) map map
A map meme which indicates that its meme has all the characteristics (min, max, legal values, ...) of another meme. In actuality this is probably an abuse of our current understanding of memes schema.

 

ISOdateFmt (MapTypes) map A19
This is a format for an ISO date/time string to the precision of seconds.
