Corpus Types

A guide to the object types used in the research corpus.

Type grammar

The corpus distinguishes object types so readers do not confuse definitions, lemmas, theorems, constructions, conjectures, remarks, and bridge claims.

The registry already exposes object IDs and book locations. Wave 3 makes the type grammar Corpus-owned metadata so the public page is no longer hand-maintaining these labels independently.

Axiom 7 current registry objects use this type.

A foundational commitment of the formal kernel.

Definition 1391 current registry objects use this type.

An introduced object, relation, construction, or term.

Lemma 107 current registry objects use this type.

A supporting result used by later statements.

Proposition 740 current registry objects use this type.

A local result or structured claim with narrower scope.

Theorem 944 current registry objects use this type.

A load-bearing result with stronger downstream use.

Corollary 33 current registry objects use this type.

A result obtained from prior statements.

Remark 915 current registry objects use this type.

Explanatory or interpretive material attached to the formal spine.

Construction 2 current registry objects use this type.

An explicit built object or method.

Why type matters

Type labels help readers decide what kind of burden a page carries. A theorem, a conjectural bridge, a definition, and an explanatory remark do not make the same kind of claim.

Reading the common types

  • Axiom: A foundational commitment of the formal kernel.

  • Definition: An introduced object, relation, construction, or term.

  • Lemma: A supporting result used by later statements.

  • Proposition: A local result or structured claim with narrower scope.

  • Theorem: A load-bearing result with stronger downstream use.

  • Corollary: A result obtained from prior statements.

  • Remark: Explanatory or interpretive material attached to the formal spine.

  • Construction: An explicit built object or method.
