Hoi.
Many items were created for Wikimania talks. They were created because
Wikimania talks represent the best practices of the Wikimedia projects. All
these talks were selected in a process to bring out the best our movement
has to offer in the many years Wikimania was held. All the persons who gave
these presentation are known by either their nick or their name as they
themselves identified them at the time of offering the presentation for
consideration/
For whatever reasons a Wikidata admin removed these items without any
discussion. In the discussion that followed other people presented the
arguments why there are no valid arguments for this deletion. A request was
made repeatedly to undelete the items involved.
Given the current state of affair there is little option but to recreate
these items. It must be noted that the current situation is problematic on
many levels. Among them it became clear that admins do as they wish and are
not held accountable for their actions. The only thing asked is for the
undeletion of items and some sober thought on what may be expected of a
Wikidata admin.
Thanks,
