submodule reference to ActiveRDF no longer working

[stepheneb]

The submodule reference in talia to your fork of ActiveRDF no longer works.

[submodule "vendor/plugins/ActiveRDF"]
    path = vendor/plugins/ActiveRDF
  url = git://github.com/net7/active_rdf_talia.git

$ git submodule update --init --recursive
Submodule 'vendor/plugins/ActiveRDF' () registered for path 'vendor/plugins/ActiveRDF'
Submodule 'vendor/plugins/assit' () registered for path 'vendor/plugins/assit'
Submodule 'vendor/plugins/semantic_naming' () registered for path 'vendor/plugins/semantic_naming'
Submodule 'vendor/plugins/widgeon' () registered for path 'vendor/plugins/widgeon'
fatal: remote error:
  Repository not found.
Unable to fetch in submodule path 'vendor/plugins/ActiveRDF'

FYI: ActiveRDF seems to be active and maintained: https://github.com/ActiveRDF/ActiveRDF
