% 0.21/0.42 % SZS output start Proof
% 0.21/0.42 Take the following subset of the input axioms:
% 0.21/0.42 fof(owl_class_objectproperty_ext, axiom, ![X]: (icext(uri_owl_ObjectProperty, X) <=> ip(X))).
% 0.21/0.42 fof(owl_class_thing_ext, axiom, ![X2]: (icext(uri_owl_Thing, X2) <=> ir(X2))).
% 0.21/0.42 fof(rdf_type_ip, axiom, ![P]: (iext(uri_rdf_type, P, uri_rdf_Property) <=> ip(P))).
% 0.21/0.42 fof(rdfs_cext_def, axiom, ![C, X2]: (iext(uri_rdf_type, X2, C) <=> icext(C, X2))).
% 0.21/0.42 fof(rdfs_ir_def, axiom, ![X2]: (ir(X2) <=> icext(uri_rdfs_Resource, X2))).
% 0.21/0.42 fof(simple_iext_property, axiom, ![S, O, P2]: (iext(P2, S, O) => ip(P2))).
% 0.21/0.42 fof(simple_ir, axiom, ![X2]: ir(X2)).
% 0.21/0.42 fof(testcase_conclusion_fullish_005_Everything_is_a_Resource, conjecture, iext(uri_rdf_type, uri_ex_s, uri_rdfs_Resource) & (iext(uri_rdf_type, uri_ex_s, uri_owl_Thing) & (iext(uri_rdf_type, uri_ex_p, uri_rdfs_Resource) & (iext(uri_rdf_type, uri_ex_p, uri_owl_Thing) & (iext(uri_rdf_type, uri_ex_p, uri_rdf_Property) & (iext(uri_rdf_type, uri_ex_p, uri_owl_ObjectProperty) & (iext(uri_rdf_type, uri_ex_o, uri_rdfs_Resource) & iext(uri_rdf_type, uri_ex_o, uri_owl_Thing)))))))).
% 0.21/0.42 fof(testcase_premise_fullish_005_Everything_is_a_Resource, axiom, iext(uri_ex_p, uri_ex_s, uri_ex_o)).
% 0.21/0.42
% 0.21/0.42 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.21/0.42 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.21/0.42 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.21/0.42 fresh(y, y, x1...xn) = u
% 0.21/0.42 C => fresh(s, t, x1...xn) = v
% 0.21/0.42 where fresh is a fresh function symbol and x1..xn are the free
% 0.21/0.42 variables of u and v.
% 0.21/0.42 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.21/0.42 input problem has no model of domain size 1).
% 0.21/0.42
% 0.21/0.42 The encoding turns the above axioms into the following unit equations and goals:
% 0.21/0.42
% 0.21/0.42 Axiom 1 (simple_ir): ir(X) = true.
% 0.21/0.42 Axiom 2 (simple_iext_property): fresh(X, X, Y) = true.
% 0.21/0.42 Axiom 3 (owl_class_objectproperty_ext): fresh10(X, X, Y) = true.
% 0.21/0.42 Axiom 4 (owl_class_thing_ext): fresh9(X, X, Y) = true.
% 0.21/0.42 Axiom 5 (rdf_type_ip_1): fresh6(X, X, Y) = true.
% 0.21/0.42 Axiom 6 (rdfs_ir_def): fresh3(X, X, Y) = true.
% 0.21/0.42 Axiom 7 (testcase_premise_fullish_005_Everything_is_a_Resource): iext(uri_ex_p, uri_ex_s, uri_ex_o) = true.
% 0.21/0.42 Axiom 8 (owl_class_objectproperty_ext): fresh10(ip(X), true, X) = icext(uri_owl_ObjectProperty, X).
% 0.21/0.42 Axiom 9 (owl_class_thing_ext): fresh9(ir(X), true, X) = icext(uri_owl_Thing, X).
% 0.21/0.42 Axiom 10 (rdf_type_ip_1): fresh6(ip(X), true, X) = iext(uri_rdf_type, X, uri_rdf_Property).
% 0.21/0.42 Axiom 11 (rdfs_cext_def_1): fresh4(X, X, Y, Z) = true.
% 0.21/0.42 Axiom 12 (rdfs_ir_def): fresh3(ir(X), true, X) = icext(uri_rdfs_Resource, X).
% 0.21/0.42 Axiom 13 (simple_iext_property): fresh(iext(X, Y, Z), true, X) = ip(X).
% 0.21/0.42 Axiom 14 (rdfs_cext_def_1): fresh4(icext(X, Y), true, Y, X) = iext(uri_rdf_type, Y, X).
