Canonical grammars

Nested parentheses grammars introduced in “Context-Free Path Queries on RDF Graphs”. Template for these grammars is described on the Nested Parentheses page.

\[\begin{split}S \, \rightarrow \, \overline{subClassOf} \, S \, subClassOf \, \mid \, \overline{subClassOf} \, subClassOf \, \\ S \, \rightarrow \, \overline{type} \, S \, type \, \mid \, \overline{type} \, type \, \\\end{split}\]

Pyformlang CFG:

S -> subClassOf_r S subClassOf | subClassOf_r subClassOf
S -> type_r S type | type_r type

---

\[\begin{split}S \, \rightarrow \, \overline{subClassOf} \, S \, subClassOf \, \mid \, \overline{subClassOf} \, subClassOf \, \\\end{split}\]

Pyformlang CFG:

S -> subClassOf_r S subClassOf | subClassOf_r subClassOf

---

\[\begin{split}S \, \rightarrow \, \overline{type} \, S \, type \, \mid \, \overline{type} \, type \, \\\end{split}\]

Pyformlang CFG:

S -> type_r S type | type_r type
