# Atomic Markdown **Domain:** Authorship / Semantic Publishing / Document Systems **Doc Type:** Canonical Concept Node **Maturity:** Operational **Related:** [[wiki/Dual-Render Composition|Dual-Render Composition]], [[wiki/Transformational Extraction|Transformational Extraction]], [[wiki/Semantic Annotation|Semantic Annotation]], [[wiki/Content Atomization|Content Atomization]] --- ## Definition **Atomic Markdown is Bryant McGill's composition-time authoring grammar for declaring autonomous quotations and reusable passages inside continuous prose.** Its visible interface is a double-brace notation, with a four-field transformational form that can produce a document surface and a separately authored quotation surface from one source span. The grammar is atomic because marked sentences and passages become independently addressable semantic objects while retaining provenance to the document that produced them. In the deployed publishing architecture, those objects can become pages, slugs, posters, feed records, search records, graph nodes, and programmable distribution inputs. ## Canonical Project Record [[projects/Dual-Render Authorship and the Atomic Markdown Double-Brace Grammar|Dual-Render Authorship: The Atomic Markdown Double-Brace Grammar]] specifies the grammar, measures its twenty-six-year corpus, reports its defects and validation requirements, reconstructs its publishing and syndication architecture, reviews prior art, and interprets its paired surfaces as human supervision for faithful decontextualization. ## See Also [[wiki/Multi-Surface Serialization|Multi-Surface Serialization]], [[wiki/Surface Realization|Surface Realization]], [[wiki/Dual-Surface Validation|Dual-Surface Validation]], [[wiki/Fractal Publishing Architecture|Fractal Publishing Architecture]], [[wiki/Ground Truth Annotation|Ground Truth Annotation]], [[wiki/Parameterized Syndication|Parameterized Syndication]]
