[NTG-context] Multiple bibliographies (bib-module, mkiv)

Dear all, I am searching for a solution where I can use two different sources of bib files separately. I found that the same question was asked before at this mail list. Since it was few years old, could I ask if there is any new work done towards it? Thanks! Peng http://www.ntg.nl/pipermail/ntg-context/2010/048290.html Hello, I need two bibliographies for my document, »Primary sources« and »Secondary sources«. Two bibliographies was created and loaded with \setupbibtex[database={prim,sec}]. But for the last step in my intention I’m looking for something to the effect that \placepublications[database=prim] or in a similar manner to \nocite{*} for every bib-database. Is there any solution or workaround? Thanks Markus
