Dear all,

is it really true that MOF contains/includes OCL?

If not so, MOF might in fact not really be defined with MOF itself but
rather its definition might rely on "external" information as Laurence
observed in his previous mail (and which also fits nicely with my
experience/understanding of MOF).

Even if OCL was part of MOF, shouldn't there then be a definition of OCL
~ in the form of a MOF meta-model? This meta-model would probably rely on
~ structural model elements of MOF (e.g. object types, ...) that are
defined using OCL in the first place. How should such a 'chicken and
egg' situation be resolved without the introduction of prior/external
knowledge of a few facts (like informally understanding what an object
type is)?

Sincerly

~  Andreas
