Hello Henry and Alan and Wolfgang!   

If I have this example, wich works really fine , I would like to know , how the same sample works

if i have a link in a footnote  and want to write \cite ,with an autor and a year ? .

\startbuffer[biblio]

@url? , what is next to write, the autor, the year? Or only the link?

}

\stopbuffer

\mainlanguage[en]

\usebtxdataset[biblio.buffer]

\starttext

\startbodymatter

  \startchapter[title={Me}]

    Your attachment actively impedes the aim that brought you to it initially

\footnote{\cite[url] [www.contextgarden.net]?

  \stopchapter

\stopbodymatter

\startbackmatter

  \startchapter[title={Bibliography}]

    \placelistofpublications

  \stopchapter

\stopbackmatter

\stoptext

Thanks for your help.
