[dwbp] Updating contributors on the BP-status

Dear all,

thank you for the call today, it was very helpful to have your agreement 
to the assigned BPs. Thank you all for contributing :-)

We updated the table [1] and there are still two BPs without member 
assignments to take care of, so we kindly ask the group if there are 
volunteers to work on the BP 6: Provide data provenance information 
<http://w3c.github.io/dwbp/bp.html#DataProvenance> and BP 27: Assess 
dataset coverage <http://w3c.github.io/dwbp/bp.html#EvaluateCoverage>.

cheers,
Berna, Carol and Newton
