Dear Taco,

I would like to add some additional fields to bibliography.

I would like to have

\newbibfield[cobissid]

\startpublication

    [...]

    ...

    \cobissid{70615}

\stoppublication

and then I would modify \setuppublicationlayout[book] to transform the

number written above into "cobiss.si-id: 70615" pointing to the

following URL:

http://www.cobiss.si/scripts/cobiss?command=DISPLAY&base=cobib&rid=70615&lani=EN

The simple answer is: search for DOI in the bib module and do whatever

that does. But, just in case:

 \unprotect

 \newbibfield[cobissid]

 \def\bibinsertcobissid#1#2#3%

   {{\bibdoifelse{\@@pb@cobissid}%

      {\edef\ascii{\@EA\detokenize\@EA{\@@pb@cobissid}}%

       #1\expanded{\goto{\@@pb@thekey}{\ascii}}#2}{#3}}}

  \protect

should come close to what you had in mind, you hyst have to tweak the

\goto arguments a bit.

Thank you very much. It was of extreme help. I'm now using

\unprotect
\def\bibinsertcobissid#1#2#3%
 {{\bibdoifelse{\@@pb@cobissid}%
     {\edef\ascii{\@EA\detokenize\@EA{\@@pb@cobissid}}%
      #1\expanded{\gotoCOBISS{\@@pb@thekey}{\ascii}}#2}{#3}}}
\protect

\def\gotoCOBISS#1#2%
 {\ifbibinteractionelse
   {\useURL[bibfoo#1][http://www.cobiss.si/scripts/cobiss?command=DISPLAY&base=cobib&rid=#2]%
    \goto{#2}[url(bibfoo#1)]}%
   {#2}}

and then

  \insertcobissid{ {\sc cobiss.si-id}: }{.}{}%

(Just for a reference in case that any other Cobiss user will ever
want to repeat the same.)

Now I have just remembered something that has bothered me earlier, but
I have never mentioned it so far. When interaction is off, DOI gets
written in plain text which is perfectly OK, but when interaction is
on, it gets written in typewriter font as if it was URL. I see no
reason for writing out DOI number in typewriter font since it's not
really URL on its own, it only points to some URL. This is exactly the
modification that I have done above for COBISS numbers. What do you
think about that aspect?

Thank you very much,
   Mojca
