This relates 1 and 3. The relation with 2 is more classical: for $X/\mathbb{C}$ an abelian variety, $H^1_{dr}(X)$ classifies rigidified vector extensions, identified with flat connections on rank 1 affine bundles. This is in the first half of Mazur-Messing. | |

I might be blind or bad at reading French, though. | |
