For preliminary binaries (contains lot of bug fixes, etc.) please ask GB Ianni (__ianni__at__mat.unical.it). == About DLT == DLT is a frontend for disjunctive datalog, extending Answer Set Programming with Template predicates, Higher order atoms and Frame Logic Syntax with nested frames. DLT works as a pre-parser and can produce output compliant with the syntax of [[http://www.dlvsystem.com|DLV]], [[http://www.mat.unical.it/kali/dlv-ex|DLV-EX]], [[http://www.kr.tuwien.ac.at/staff/roman/dlvhex/|DLV-HEX]], and, partially, [[http://www.tcs.hut.fi/Software/smodels/|Lparse+Smodels]] <> ---- == The Team == Project Coordinator * [[http://www.gibbi.com|Giovambattista Ianni]] Sr. Developers * [[http://www.mat.unical.it/calimeri|Francesco Calimeri]], Giuseppe Ielpa Jr. Developers * [[mailto:cozza_AT_mat.unical.it|Susanna Cozza]], [[mailto:a.pietramala_AT_mat.unical.it|Adriana Pietramala]], [[mailto:santoro_AT_mat.unical.it|Maria Carmela Santoro]], [[mailto:a.martello_AT_mat.unical.it|Alessandra Martello]], [[mailto:gisella_bennardo_AT_yahoo.it|Gisella Bennardo]], [[mailto:mario.alviano_AT_gmail.com|Mario Alviano]], [[mailto:marano_AT_mat.unical.it|Marco Marano]] Contact us at dlt_AT_mat.unical.it.

DLT works at its best with the [[https://www.mat.unical.it/dlv-complex|DLV-Complex]] binary. The official DLV binary can be found [[http://www.dlvsystem.com|here]]. A limited compatibility with lparse/gringo input format is also provided.

This web interface currently runs DLT 1.5.1).

It has been implemented and is currently maintained by members of the DLV team from Università della Calabria (some of them are involved also into the DLT project). Sooner DLV-EX features will be part of the DLV System. * [[http://www.mat.unical.it/dlv-complex|DLV-Complex]] extends DLV-EX with function symbols, lists and set terms. * [[http://www.kr.tuwien.ac.at/staff/roman/dlvhex/|DLV-HEX]] features "''second order''" external predicates taking relational input an returning relational output, as well as higher order atoms. <> ---- == Selected Publications == {{{[AIMMM+08]}}} Mario Alviano, Giovambattista Ianni, Alessandra Martello, Marco Marano.
