Abstract Developers reuse source code ﬁles in other project and library to develop large software eﬃciently. A
license of the software must meet their licenses. In this paper, we extract inclusion order among software licenses
from open source software. We conducted empirical study using a set of source packages in Fedora 17 as a set ofopen source software. The result shows that we can extract inclusion order from source package and we can connect
these relations. In addition, based on these inclusion relations, we also show that license inconsistency may occur.
Key words Reuse, Software license, Software package, Open source software, Partial Order
