Header Dictionary Triples (HDT) for SWI-Prolog

This repository is work in progress to provide access to HDT files from SWI-Prolog based on the C++ library for these files.

HDT files form a natural addition to SWI-Prolog's memory based RDF store to access large amounts of static background knowledge without enlarging the memory footprint.

This repository is organised as a SWI-Prolog pack. To install it, perform the steps below. Installation and usage is tested on Ubuntu and Fedora. This should work on most Unix-like machines. Installation on Windows requires more creativity though.

Installation

  1. Install a recent version of Serd:
curl -s http://download.drobilla.net/serd-0.26.0.tar.bz2 | tar -xj && \
  cd serd-0.26.0 && \
  ./waf configure && \
  ./waf && \
  sudo ./waf install;

  1. Install Raptor2.

    On Fedora: sudo dnf install raptor2-devel

    On Ubuntu: sudo apt-get install libraptor2-dev

  2. After the prerequisites are installed, the HDT library can be installed from within Prolog using the following command:

?- pack_install(hdt).

Usage

If the installation went well, you can load the HDT library with the following command:

?- [library(hdt)].

Status

Usable, but still experimental.
