Dependency:

Please install boost and raptor, you can use the following versions or other versions.

boost-1.39.0.tar.gz raptor-1.4.21.tar.gz

On Ubuntu 18.04 / 18.10 / 19.04 / 19.10 run the commands below to install the perquisites for building TripleBit.

## install perquisites via apt
sudo apt install librdf0-dev libxml2-dev flex bison autopoint gtk-doc-tools libtool m4 automake gcc g++ build-essential git libboost-all-dev cmake
## compile old versions of libraries that are no longer in the ubuntu apt repos 
# old curl for raptor 
wget https://curl.haxx.se/download/archeology/curl-7.19.7.tar.gz
tar -xvzf curl-7.19.7.tar.gz
cd curl-7.19.7/
./configure
make -j
sudo make install

Building:

TripleBit must be build using GNU make and a reasonable C++ compiler. Ideally a simple

make

is enough, it will build the tree high-level executables in bin/lrelease/.

Using:

TripleBit currently includes three high-level executables. The first buildTripleBitFromN3) is used to build a new database from an turtle/ntriples input:

buildTripleBitFromN3 mydata.n3 database_directory

The input file can be arbitrarily large, the buildTripleBitFromN3 spools to disk if main memory is exhausted.

The second (buildTripleBitFromRDF) is similar to the first executable except the input file is a rdf file.

After loading the database can be queried with triplebitQuery:

triplebitQuery database_directory query_directory

triplebitQuery database_directory

The program shows a command prompt and accept SPARQL queries. Just type your SPARQL query in a single line and press ENTER.

Note: TripleBit currently only supports "select" queries.
