[Verse 1]
Start with words that matter most, define each term with crystal precision
SBVR principles guide your vocabulary, no ambiguity or derision
Every concept needs a definition, compliance domains require control
Formal language starts with meaning, let semantics play their role
[Chorus]
Five layers deep, we're climbing high
Vocab, authoring, data, enforce, verify
ACE patterns make it readable
OSCAL keeps it traceable
From controlled terms to Rego rules
These are your formal language tools
[Verse 2]
Actor, action, object, frequency, condition complete the frame
Write your controls with ACE-like structure, semi-formal is the game
Human eyes can read the statement, machines can parse it too
Bridge the gap 'tween documentation and what computers do
[Chorus]
Five layers deep, we're climbing high
Vocab, authoring, data, enforce, verify
ACE patterns make it readable
OSCAL keeps it traceable
From controlled terms to Rego rules
These are your formal language tools
[Bridge]
Layer three brings OSCAL magic, catalogs become machine-read
Framework mappings, assessment data, interoperability fed
Cedar, Rego for enforcement, trace back to original source
Deontic logic for the critical, verify with formal force
[Verse 3]
Not every control needs full formalization, choose your battles wise
High-risk domains get verification, consistency analyzed
Pragmatic layering beats perfection, incremental wins the day
Management controls need structure, formal languages show the way
[Chorus]
Five layers deep, we're climbing high
Vocab, authoring, data, enforce, verify
ACE patterns make it readable
OSCAL keeps it traceable
From controlled terms to Rego rules
These are your formal language tools
[Outro]
Vocabulary first, enforcement last
Each layer builds upon what's passed
Formal languages tame complexity
Your compliance speaks with clarity
