Looking at the licensing terms for Pellet 2.0, it is not really about the
type of the user, but rather about the application Pellet 2.0 is part of. It
can be used for free only if it is a part of an open source application,
otherwise, it requires a commercial license.

Subject: [tbc-users] Re: xsd:tme and pellet


Thomas,

when Clark and Parsia announced (a few months back) that Pellet would become
dual-license, we made a user survey to find out how important OWL 2 and
Pellet are for our user base. It turned out that there was almost no
interest in those technologies.

We do not bundle any commercial software as part of the TBC download, only
drivers to commercial software such as Oracle. It would complicate our
licensing model if we shipped Pellet, because depending on the type of user,
they would need to acquire license keys first before using Pellet.

So if there were more demand we could certainly revisit this decision.  
We take your vote into consideration but still this does not change our
plans yet. If anyone knows of alternative implementations of OWL 2 beside
commercial options, please let us know.

Holger
