% 123.34/16.20  
% 123.34/16.20  % SZS output start Proof
% 123.34/16.20  Take the following subset of the input axioms:
% 123.34/16.20    fof(conclusion_rdfbased_sem_prop_topdataproperty_ext_lo, conjecture, iext(uri_owl_topDataProperty, uri_ex_x, uri_ex_y)).
% 123.34/16.20    fof(owl_parts_lv_def, axiom, ![X]: (lv(X) <=> iext(uri_rdf_type, X, uri_rdfs_Literal))).
% 123.34/16.20    fof(owl_prop_topdataproperty_ext, axiom, ![Y, X2]: (iext(uri_owl_topDataProperty, X2, Y) <=> (ir(X2) & lv(Y)))).
% 123.34/16.20    fof(premise_rdfbased_sem_prop_topdataproperty_ext_lo, axiom, iext(uri_rdf_type, uri_ex_y, uri_rdfs_Literal) & iext(uri_rdf_type, uri_ex_x, uri_owl_Thing)).
% 123.34/16.20    fof(simple_ir, axiom, ![X2]: ir(X2)).
% 123.34/16.20  
% 123.34/16.20  Now clausify the problem and encode Horn clauses using encoding 3 of
% 123.34/16.20  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 123.34/16.20  We repeatedly replace C & s=t => u=v by the two clauses:
% 123.34/16.20    fresh(y, y, x1...xn) = u
% 123.34/16.20    C => fresh(s, t, x1...xn) = v
% 123.34/16.20  where fresh is a fresh function symbol and x1..xn are the free
% 123.34/16.20  variables of u and v.
% 123.34/16.20  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 123.34/16.20  input problem has no model of domain size 1).
% 123.34/16.20  
% 123.34/16.20  The encoding turns the above axioms into the following unit equations and goals:
% 123.34/16.20  
% 123.34/16.20  Axiom 1 (simple_ir): ir(X) = true2.
% 123.34/16.20  Axiom 2 (premise_rdfbased_sem_prop_topdataproperty_ext_lo_1): iext(uri_rdf_type, uri_ex_y, uri_rdfs_Literal) = true2.
% 123.34/16.20  Axiom 3 (owl_parts_lv_def): fresh253(X, X, Y) = true2.
% 123.34/16.20  Axiom 4 (owl_prop_topdataproperty_ext_2): fresh157(X, X, Y, Z) = iext(uri_owl_topDataProperty, Y, Z).
% 123.34/16.20  Axiom 5 (owl_prop_topdataproperty_ext_2): fresh156(X, X, Y, Z) = true2.
% 123.34/16.20  Axiom 6 (owl_parts_lv_def): fresh253(iext(uri_rdf_type, X, uri_rdfs_Literal), true2, X) = lv(X).
% 123.34/16.20  Axiom 7 (owl_prop_topdataproperty_ext_2): fresh157(lv(X), true2, Y, X) = fresh156(ir(Y), true2, Y, X).
% 123.34/16.20  
% 123.34/16.20  Goal 1 (conclusion_rdfbased_sem_prop_topdataproperty_ext_lo): iext(uri_owl_topDataProperty, uri_ex_x, uri_ex_y) = true2.
% 123.34/16.20  Proof:
% 123.34/16.20    iext(uri_owl_topDataProperty, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 4 (owl_prop_topdataproperty_ext_2) R->L }
% 123.34/16.20    fresh157(true2, true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 3 (owl_parts_lv_def) R->L }
% 123.34/16.20    fresh157(fresh253(true2, true2, uri_ex_y), true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 2 (premise_rdfbased_sem_prop_topdataproperty_ext_lo_1) R->L }
% 123.34/16.20    fresh157(fresh253(iext(uri_rdf_type, uri_ex_y, uri_rdfs_Literal), true2, uri_ex_y), true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 6 (owl_parts_lv_def) }
% 123.34/16.20    fresh157(lv(uri_ex_y), true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 7 (owl_prop_topdataproperty_ext_2) }
% 123.34/16.20    fresh156(ir(uri_ex_x), true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 1 (simple_ir) }
% 123.34/16.20    fresh156(true2, true2, uri_ex_x, uri_ex_y)
% 123.34/16.20  = { by axiom 5 (owl_prop_topdataproperty_ext_2) }
% 123.34/16.20    true2
% 123.34/16.20  % SZS output end Proof
% 123.34/16.20  
% 123.34/16.20  RESULT: Theorem (the conjecture is true).
