Discurso Institucional

Hi everyone,

I am having a terrible time translating the following sentence, especially with respect to the expression: "Discurso Institucional". Can someone please help me??? Thanks very very much.

Es según este modelo como hemos organizado finalmente los diferentes relatos de investigación, que han tomado forma de tres grandes ejes (1/ La idea de arte e interpretación en el discurso institucional.

Unless you know something I don't, I can't see why you couldn't translate it literally:

We have finished organizing the different accounts of investigation according to a model that has taken the form of three large axes (1/ The idea of art and interpretation in institutional discourse.

Oops. Of course, in English, we would say "major axes" instead of large axes.
