Motivation (1)<br />

◮ Model and proof theory complementary (soundness,<br />

completeness), but also in philosophical conflict<br />

◮ Successful logical frameworks focusing on one of the two:<br />

◮ institutions, the most successful model theoretical framework<br />

◮ dependent type theory (LF), the most successful proof<br />

theoretical framework<br />

◮ Complementary strengths:<br />

◮ institutions: abstraction over concrete syntax, strong support<br />

for translations<br />

◮ dependent type theory: elegant syntax, strong support for<br />

effective reasoning<br />

◮ Goal: Give a logical framework that combines and subsumes<br />

institutions and dependent type theory<br />
