Thanks Luigi!

It turns out that with some slight modifications I could typeset the mentioned project with mkiv. 
Then after having added the following from your article:

%% For PDF/A
\setupbackend[
format={pdf/a-1a:2005},
profile={default_cmyk.icc,
         default_rgb.icc,default_gray.icc},
intent={%
ISO coated v2 300\letterpercent\space (ECI)}
]
%% Tagged PDF
%% method=auto ==> default tags by Adobe
\setupstructure[state=start,method=auto]

I could get a PDF which looks fine: but now I have to make sure that it is PDF/A compliant.
Right now I don’t hav etime to check this, but in any case you gave me good hope… Thanks!

Best regards: OK

Thanks Luigi for the hint to that paper.
Unfortuantely the project has been done with mkii… that’s why I would like to know if it’s possible to produce a PDF/A compliant file with ConTeXt mkii.
By the way, is there an easy way to check whether a PDF file is PDF/A compliant?

Best regards: OK
afaik there is only and experimental extension of pdftex that used with latex can make pdf/a-1a (tagged pdf) -- but i'm not sure. 

But pdf/a-1b are different (not tagged) so you can use ghostscript, even if it's not easy.
Here an article by C: Beccari for xelatex
