With what standards does CDISC SHARE comply, beyond CDISC? 

CDISC SHARE's metamodel allows us to specify how content within a standard is related and how different standards relate to one another. CDISC SHARE features a CDISC metamodel that implements the international ISO/IEC 11179 standard for metadata registries. We use it to define and register normative standards content such as variables or domains from CDISC standards, such as SDTM, CDASH, Controlled Terminology, etc.
