This package is intended to be a collection of modules for
interacting with OpenLink Virtuoso
_ from python.
The goal is to provide drivers for SQLAlchemy
and RDFLib
.
At the time of this writing it requires a fork of pyodbc, which you can find on this branch: https://github.com/maparent/pyodbc/tree/v3-virtuoso
It can be installed normally with pip install -r requirements.txt
You have to set up your ~/.odbc.ini
(or /etc/odbc.ini
) file with a block similar to this:
::
[VOS]
Description = Open Virtuoso
Driver = /usr/local/virtuoso-opensource/lib/virtodbcu_r.so
Address = localhost:1111
Locale = en.UTF-8
Most parameters depend on your installation, but be sure to use virtodbcu_r.so
as opposed to any other variant. Wo have used virtuoso 7.1 in production, and also virtuoso 6.1. As of this writing, there is an issue with using LONG VARCHAR columns in virtuoso 7.2.

This package also contains an experimental generator of Virtuoso Linked Data Views, which was presented as a poster at ISWC2014: http://ceur-ws.org/Vol-1272/paper_60.pdf
The original design of this library is by William Waites
, and development is continued by Marc-Antoine Parent
for an earlier stage of the Assembl
project.
