      Wolfgang—

Can this be extended so as to allow the extraction of the individual
component files (as PDFs with their component names) when processing a
product file?

Hello,
In the production of (scientific) articles for journal submissions,
one is often expected to supply the figures as separate files.
One workflow can be through the use of \startTEXpage\stopTEXpage
followed by an external extraction of single pdf pages to separate
files.
However, is it possible or would it be possible to directly output to a
named file, as in:
     \startTEXpage{figure1.pdf}
     \stopTEXpage
or perhaps
     \startTEXpage [file=figure1.pdf]
     \stopTEXpage
? (I could not find an answer looking at the source.)
One could then (optionally) reinclude the figure in a review copy of
the full text through the use of \externalfigure [figure1]
You can put each graphic in a separate document and tell context to
create a pdf with the \typesetfile command.
\startbuffer[extract:before]
  \startTEXpage
\stopbuffer
\startbuffer[extract:after]
  \stopTEXpage
\stopbuffer
\def\startextract
  {\dosingleempty\dostartextract}
\def\dostartextract[#1]%
  {\edef\extractfilename{#1}%
   \grabbufferdata[extract:content][startextract][stopextract]}
\def\stopextract
  {\doifsomething\extractfilename
{\savebuffer[list={extract:before,extract:content,extract:after},file=\extractfilename.tex,prefix=no]%
      \typesetfile[\extractfilename][]}}
\starttext
\startplacefigure[title={External file}]
  \startextract[extract-1]
  \blackrule[width=4cm,height=4cm,color=orange]
  \stopextract
\stopplacefigure
\stoptext
...
Creating a new environment which does all of this itself isn’t hard
because most of the stuff which is needed can be seen in the example
below.
% the external file
\startbuffer[figure-1]
\startTEXpage
\blackrule[width=4cm,height=4cm,color=blue]
\stopTEXpage
\stopbuffer
\savebuffer[list=figure-1,file=figure-1.tex,prefix=no]
% process the external file at runtime
\starttext
\placefigure{External file}{\typesetfile[figure-1]}
The second argument for \typesetfile is needed to get this working:
\placefigure{External file}{\typesetfile[figure-1][]}
