[gme-users] Equivalents of MetaGME's Reference and Set

[Sumant Tambe]

Hi,

MetaGME's Reference and Set are quite useful metamodeling tools. I was 
wondering whether other metamodeling technologies such as MOF, EMOF, 
ECore, XSD have comparable features. If yes, can you please tell me what 
they are and where they are documented?

Thanks,

Sumant.
