Enterprise Architecture OKF

A corpus, not a wiki

At the center of it sits the Corpus: one official archive, not a loose collection of documents that happen to be true. Everything inside the Corpus is part of the governed record, but corpus membership alone does not place an artifact in force — authority arises through the applicable issuance or authorization mechanism (Auctoritas). Everything outside the Corpus — notes, drafts, working files — is evidence: useful, but not part of the governed record at all. That distinction is what keeps a growing body of decisions from quietly drifting out of sync with what a practice actually does.

What it actually holds

A small number of entity kinds, kept cleanly separated: the Intent a practice exists to serve; Principles and Constraints that rarely change; named Standards the practice measures itself against (this is exactly where a maturity model like the ones in this family lives); Decision Records for choices already made, so they aren't re-litigated; Work Packages with a clear scope and owner; Authorizations — formal, constitutive acts by which a human owner sanctions specific work; the Systems and Operations doing the actual work day to day; and Observations, the feedback that sharpens Intent over time as those systems actually run.

Where the models in this family stand

EA OKF represents and connects the architecture; it is not the architecture itself, and not one of the models. Each model is the actual product: a named Standard, expressed as structured, machine-readable governance rather than a one-off document. Strata is the structure explaining how they relate to each other once they're in place.
