Many thanks for your reply and your explanation, Wolfgang.

I can provide at the moment solutions which ensure the information appear in the PDF but none of the is very elegant and I hope Hans can help with a clean solution.

The first one avoids the issue until Hans provides a final fix.

Here is the official solution: \startxmlsetups xml:meta \setupmetadata [author={\xmltext{#1}{/author}}, title={\xmltext{#1}{/title}}] \stopxmlsetups The command is new and accepts the following keys: - title - subtitle - author - keyword - date Wolfgang

So now we have:

\setupinteraction [title=FooBar]

\setupdocument [metadata:title=FooBar]

\setupmetadata [title=FooBar]

Are any of those deprecated or the preferred way? I'm starting to get confused.

There’s also \settaggedmetadata; I actually didn’t know \setupmetadata. Both are missing in the wiki yet. Also https://wiki.contextgarden.net/Command/setupinteraction doesn’t talk about metadata. Sigh. AFAIK the metadata from \setupinteraction is used for everything, as long as you don’t overwrite it elsewhere. Hraban

that's for those who go global

Many thanks for the new command, Hans. I‘m afraid this new command breaks my compilation. The error message isn’t very helpful for me (see below). I wonder whether this requires a minimal sample to be fixed.

Yes, a minimal example would help because \setupmetadata works in your previous example.

Many thanks for your reply, Wolfgang. Now I have the minimal sample: \startbuffer[demo] <doc> <div id="header"> <h2 class="author">author</h2> </div> <text> text </text> </doc> \stopbuffer \starttext \startxmlsetups xml:initialize \xmlsetsetup{#1}{doc}{xml:*} \xmlsetsetup{\xmldocument} {(div|section)[@id='header']} {xml:meta} \xmlsetsetup{\xmldocument} {(h2|p)[contains(@class,'author')]} {xml:title:author} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:text \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:meta %\aftergrouped{\setupinteraction% \setupmetadata [author={\xmlconcat{#1}{/h2[contains(@class,'author')]}{, }}] %} \stopxmlsetups \startxmlsetups xml:title:author \xmlflush{#1} \stopxmlsetups \setupinteraction[state=start] \xmlprocessbuffer{main}{demo}{} \stoptext With \setupmetadata it breaks compilation. I know it is not the most elegant code, but in my real environment xml:title:author outputs text. Many thanks for your help, Pablo
