N-GraphML: Language and Formal Grammar for Proof-Graphs
Daniel Vaz dos Santos, Lucas Fernando Souza de Castro, Gleifer Vaz Alves · 2013
N-Graphs is a formal proof system based on natural deduction and sequent calculus rules, where derivations are represented via proof-graphs. The N-GraphML language has been developed in order to define a computational representation for N-Graphs. Here our work has a two-fold goal: i. define a formal grammar for N-GraphML, ii. build a proof editor for N-Graphs.
