WLCG evolution
--------------

In June 2015, OSG announced their plans to stop using the BDII to publish their
computing resources (See :download:`Slides <files/WLCGOpsCoord-OSGBDII.pdf>`
presented at the WLCG Operations Coordination Meeting in 18th of June). This
announcement has triggered the review of the current WLCG Information System.
It has been decided to create a
`task force <https://twiki.cern.ch/twiki/bin/view/EGEE/WLCGISEvolution>`_
to evaluate how WLCG is going to evolve to be able to cover the existing use
cases and finally improve all the existing drawbacks and weaknesses of its
current implementation.
