ConTeXt Project Structure: Add metadata to component

Question

I am setting up a project structure for a new journal and I want to use a structure like the one in this answer. However, instead of using document:start I tried \startsetups component:start, but no results.

My structure looks like this:

• test.tex

\startproject *
\environment test_env

\product test_prod

\stopproject

• test_env.tex

\startenvironment *

\setuphead
    [section]
    [textstyle=\em]

\startsetups component:start
  \startalignment[middle]
    {\bfa\setupinterlinespace 
    This should appear somewhere!
     \endgraf}
    \blank[big]
   \stopalignment
\stopsetups

\stopenvironment

• test_prod.tex

\startproduct *
\project test

\component test_comp

\stopproduct

• test_comp.tex

\startcomponent *
\product test_prod
%\project test

\section{Test}

Blabla


\stopcomponent

Answer 1

There is not component:start. The idea is that you only set metadata for the whole document once when you place \startdocument. If you still want to insert your setups before \startcomponent you can write

\directsetup{component:start}
\startcomponent

or more programmatically

\prependvalue{startcomponent}{\directsetup{component:start}}

Of course this has to be placed before the first \startcomponent.
