About DLT

DLT is a frontend for disjunctive datalog, extending Answer Set Programming with Template predicates and Frame Logic Syntax.

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/ Smodels]

Download

Linux (i586) and Windows (32) binaries are available (updated June 10th, 2007).

• Download the [attachment:dlt.linux.1.5.1.tar.gz latest linux (i586) version] (1.5.1).
• Download the [attachment:dlt.win.1.5.1.zip latest windows version] (1.5.1).

Note: since DLT invokes DLV, you will need the DLV executable. Please find all versions at the official [http://www.dlvsystem.com DLV webpage]. A limited compatibility with other solvers is also provided (see for instance [http://www.tcs.hut.fi/Software/smodels/ Smodels]).

• [http://www.mat.unical.it/kali/dlv-ex DLV-EX] is an Answer Set Programming System with External Predicates, featuring a framework aimed at enabling ASP to deal with external sources of computation. 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. It allows DLT as a pre-parser.

• [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. It allows DLT as a pre-parser.
