Hi everyone, I really have difficulties with the bibliograpy system. Sorry about that. I would like to print the whole bibliography so I followed mkiv-publications.pdf and ended up with the file:

\usebtxdataset[example][./mkiv-publications.bib]

\definebtxrendering
  [example]
  [dataset=example,
   method=local,
   alternative=apa]

\starttext

\showbtxdatasetfields[example]
\placebtxrendering
  [example]
  [criterium=all]

\stoptext
