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.
- 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;
-
Install Raptor2.
On Fedora:
sudo dnf install raptor2-devel
On Ubuntu:
sudo apt-get install libraptor2-dev
-
After the prerequisites are installed, the HDT library can be installed from within Prolog using the following command:
?- pack_install(hdt).
If the installation went well, you can load the HDT library with the following command:
?- [library(hdt)].
Usable, but still experimental.
