Support field in biblatex entries to overwrite citation formatting

[ghost]

Dear all,

I am confronted with issues due to weak intercomperability between special-purpose biblatex packages (oscola and the CSL oscola. I mentioned this problem previously here in issue #435 .

I think one solution would be to have pandoc-citeproc look in the biblatex bibliography for a special field like cite_overwrite = {citation \textit{here}} and use this one instead of the output from the CSL algorithm. Of course, this would prevent switching easy citation styles, but at least I could use the same bibliography file for biblatex and pandoc-citeproc.

Example of citations that I cannot produce with pandoc-citeproc from biblatex bibliography files:

My guess is that the biblatex-CSL crossover you’re proposing isn’t really on the cards.

However, it does seem there might be room for improvement concerning the treatment of legal material in pandoc-citeproc.

Currently, pandoc-citeproc -y file.bib converts your example from #435 to the following (CSL YAML for better readability, but CSL JSON fields should be identical):

If you could indicate what CSL field content does produce satisfactory results with pandoc-citeproc using oscola.csl, I am sure we could have a closer look at how to improve the biblatex -> CSL conversion process.

BTW, wrapping entire bib(la)tex title fields in braces is counterproductive. Only individual terms/phrases such as names should be protected in this way.
