BibTeX, biblatex and biber ⇒ using bib keywords in the document

[jena]

Hi all,

I was wondering if there is any tool like biblatex (or biblatex itself?) which can extract keywords from the bib records? Something like \citekeywords{bibkey} (similar to \citeauthor or \citetitle in biblatex). I would like to have the author, title and keywords in my document for quick reference.

Another use would be an index at the end of the document over bib keywords. Something like:

optimisation .............. [1], [4], [12]
problem formulation ....... [1], [3]
...

Or having an automatically generated table with rows for keywords and columns for papers and 'X' in each cell when a paper is annotated with a particular keyword.

I was searching the web but so far without success. Thanks for any help!
