#3 virtuoso in RDFLIB

[Daniele Santamaria]

Dear team, there is any upgrade of the virtuoso plug-in for python 3.x and the latest version of RDFLib.
When I try to install the library via pip I receive the error:

Collecting virtuoso Using cached https://files.pythonhosted.org/packages/95/3b/110a435f7bed5e9dbade1a6f213ddb98352a70524e92a09ddc2e5df0a59f/virtuoso-0.12.6.tar.gz Collecting pyodbc==virtuoso-2.1.9-beta14 (from virtuoso) Could not find a version that satisfies the requirement pyodbc==virtuoso-2.1.9-beta14 (from virtuoso) (from versions: 2.1.1, 2.1.2, 2.1.3, 2.1.4, 2.1.5, 2.1.6, 2.1.7, 2.1.8, 2.1.9, 2.1.10, 2.1.11, 3.0.3, 3.0.6, 3.0.7, 3.0.8, 3.0.9, 3.0.10, 3.1.1, 4.0.1, 4.0.2, 4.0.3, 4.0.5, 4.0.6, 4.0.7, 4.0.8, 4.0.9, 4.0.10, 4.0.11, 4.0.12, 4.0.13, 4.0.14, 4.0.15, 4.0.16, 4.0.17, 4.0.18, 4.0.19, 4.0.20, 4.0.21, 4.0.22, 4.0.23, 4.0.24, 4.0.25, 4.0.26, 4.0.27, 4.0.28, 4.0.30b1, 4.0.30) No matching distribution found for pyodbc==virtuoso-2.1.9-beta14 (from virtuoso)

Many thanks.

After forcing the installation and executing a simple example I receive:

Traceback (most recent call last):
  File "D:\Python37\lib\site-packages\rdflib\plugin.py", line 100, in get
    p = _plugins[(name, kind)]
KeyError: ('Virtuoso', <class 'rdflib.store.Store'>)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/danie/PycharmProjects/EndpointTest/python/virtuoso/virtuoso-wrap.py", line 4, in <module>
    Virtuoso = plugin("Virtuoso", Store)
  File "D:\Python37\lib\site-packages\rdflib\plugin.py", line 103, in get
    "No plugin registered for (%s, %s)" % (name, kind))
rdflib.plugin.PluginException: No plugin registered for (Virtuoso, <class 'rdflib.store.Store'>)

Hi Daniele,

The Python RDFLib was not built or maintained by OpenLink Software and does not seem to have been updated since 2011. The question would be best asked of the maintainers of the package at https://pypi.org/project/virtuoso/ ...

Ok, I contact the team and update this ticket ASAP. Many thanks!.
