Pack hdt -- README.md |
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.
The currently installed version can be found by the command serdi
-v
. The minimum version of Serd is 0.28.0 (see hdt-cpp/README.md
or
the before_install
rule in `hdt-cpp/.travis.yml`).
If that isn't available, it can be installed and built by:
curl -s http://download.drobilla.net/serd-0.30.0.tar.bz2 | tar -xj && \ cd serd-0.30.0 && \ python2 ./waf configure && \ python2 ./waf && \ sudo ./waf install;
You may wish to specify `--prefix=/usr/local or
--prefix=$HOME/.local
to
waf configure`.
You can uninstall by `python2 ./waf uninstall`
On Ubuntu: `sudo apt-get install libraptor2-dev`
?- pack_install(hdt).
If the installation went well, you can load the HDT library with the following command:
?- [library(hdt)].
Usable, but still experimental.
