Dear Alan,
Thank you very much for your reply. Unfortunately, I don’t get this working. Also, I don’t find the documentation for flushbtxrendering.
Here’s a minimal working example I’m trying:

\startbtxrenderingdefinitions[mybib]

\definebtx
  [mybib]
  [default=default,
   specification=mybib]

\definebtxrendering
  [mybib]
  [specification=mybib,
   numbering=yes]

\stopbtxrenderingdefinitions

\startsetups btx:mybib:list:link
   \btxdoifelse {title} {\btxflush{title}:\space} {No Title}
   \btxdoifelse {url}  {\btxflush{url};\space} {}
   \btxdoifelse {date}  {abgerufen \btxflush{date}.} {}
  \removeunwantedspaces
\stopsetups

\startsetups btx:mybib:list:imagelink
   \btxdoifelse {url}  {\btxflush{url};\space} {}
   \btxdoifelse {date}  {abgerufen \btxflush{date}.} {}
  \removeunwantedspaces
\stopsetups


\startbuffer[maindata]
@link{herbariumathome,
    title={Herbarium At Home: A Beginner's Guide},
    url={https://youtu.be/2kEbCaTe8XM},
    date={04.04.2024}},

@imagelink{zooniverse_logo,
    url={https://www.sciencelearn.org.nz/images/3873-zooniverse-logo},
    date={04.06.2024}}
\stopbuffer
% enable tracing
\enabletrackers[publications, publications.crossref, publications.details, publications.cite, publications.strings]

\definebtxdataset[main]
\usebtxdataset[main][maindata.buffer]
%\definebtxdataset[bilder]
%\usebtxdataset[bilder][imagedata.buffer]
\usebtxdefinitions[mybib, aps] % aps for stuff which isn’t a link or image
\setupbtx[dataset=main]
\definebtxrendering[bibrendering][mybib, aps][dataset=main]

\starttext
\cite[herbariumathome]
\cite[zooniverse_logo]

\section{Quellen: Bilder}
%\placelistofpublications[bibrendering]
\flushbtxrendering [bibrendering]
[method=dataset,
 sorttype=index,
 filter=match(category:imagelink)]

\section{Quellen: Webseiten}
\flushbtxrendering [bibrendering]
[method=dataset,
 sorttype=index,
 filter=match(category:link)]
\stoptext

I would very much appreciate more ideas.

Thank you very much and kind regards

Ben

Try something like:

     \flushbtxrendering [bibrendering]

       sorttype=index,
       filter=match(category:article)]

I have used the filtering mechanism to select fields, such as filter=match(year:2023).

Hey there,
I would like to place a list of bibliography according to types
(article, book, in proceedings) in my document. Similar like here:
https://tex.stackexchange.com/questions/112874/sectioning-bibliography-by-type-with-multiple-types-per-section
Sectioning bibliography by type (with multiple types per section)
tex.stackexchange.com

and here:
https://www.mail-archive.com/ntg-context@ntg.nl/msg77056.html
The example provided by Hans doesn’t seem to properly work any more,
and I cannot make the suggestion work of using two different datasets
work as suggested in the same thread. So this is where I’m stuck:

\definebtxdataset[main]
\usebtxdataset[main][maindata.buffer]
\definebtxdataset[images]
\usebtxdataset[images][imagedata.buffer]
\usebtxdefinitions[mycustom, aps]
\setupbtx[dataset=main]
\definebtxrendering[bibrendering][mycustom, aps][dataset=main]
\definebtxrendering[bibimgrendering][mycustom, aps][dataset=images]

\placelistofpublications[bibrendering]
\placelistofpublications[bibimgrendering]

It would be much appreciated if someone could provide a working
example?

Thank you very much

Ben
