Learn English – the difference between ‘curricula’ and ‘curriculum’

In India, curd is marketed as "yoghurt."

see http://en.wikipedia.org/wiki/Curd

Curd and Yoghurt are indeed used interchangeably in many parts of (mostly urban) India and the region in general, though probably not in the UK, the US and some other parts of the world. (Thanks to @Peter Shor for the guidelines).

'[Rahmencurriculum]1' (Ger.) translates to model curriculum (curriculum according to a specific framework) in English. The reference is to curriculum.

It is clearly not curricular framework in OP's case.

[EDIT]
A framework curriculum is a sample/ model built on the basis of guidelines (the 'framework'). Individual institutions can design their curricula on this model, or probably adopt it as such.

A curricular framework (loosely, curriculum framework) is a set of guidelines defining and explaining what a curriculum is required to be like or contain.
