One more btx issue. The output from the following \startbuffer[TestBib] @FILM{Film1, producer = {Lasta, A.}, director = {Lastb, B.}, title = {Title1}, year = {2017}, publisher = {Publisher}, address = {Address}, } @FILM{Film2, producer = {Lasta, A.}, director = {Lastc, C.}, title = {Title2}, year = {2017}, publisher = {Publisher}, address = {Address}, } \stopbuffer \loadbtxdefinitionfile[apa] \usebtxdefinitions [apa] \usebtxdataset [TestBib.buffer] \definebtxrendering [Pubs][apa] \enabletrackers[publications.authorhash] \starttext \placelistofpublications[Pubs][method=dataset] \stoptext is incorrect. The director of the second film is lost, and the use of a bib dash makes it look like Film1 director is associated with Film2. There should be two separate entries: Lasta, A. (Producer), & Lastb, B. (Director) (2017). /Title1./ [Motion picture]. Address: Publisher. Lasta, A. (Producer), & Lastc, C. (Director) (2017). /Title2./ [Motion picture]. Address: Publisher. -- Rik
