Proper formulation of "contribute to" in subordinate sentence

I am writing a text about our project (say Project A), and I want to say that something which I am talking about (the three dots below), was motivated by requirements of project X, which I didn't talk about before. I want to say that our project A contributed the data to project X and the requirements of project X were a motivation for something I am talking before. I wanted to say it all simply in a subsentence (or subordinate clause or how do you call it). Could it be said like this? :

... It was also motivated by the requirements of Project X, to which the data from our project also contributed.

or like this? :

... It was also motivated by the requirements of Project X, where the data from our project also contributed.

Solution 1:

Neither of those is quite right. Your project contributed its data; the data wasn’t a contributor. Try:

It was also motivated by the requirements of Project X, to which our project also contributed data.

That is the more formal version of:

It was also motivated by the requirements of Project X, which our project also contributed data to.

You could also simply say:

It was also motivated by the requirements of Project X, which used data from our project.

(Without further context, I’m not certain the second also belongs in any of the above.)
