1 Single-Vendor Commercial Open Source Business Model
OOSMOS, LLC uses the Single-Vendor Commercial Open Source Business Model as
a paper by Dirk Riehle
of Friedrich-Alexander-University in Erlangen, Germany.
Because OOSMOS, LLC owns the copyright to
we are able to offer two licenses:
One very important aspect of this business model is that we
cannot accept outside contributions to the code base unless the contributor
transfers the copyright to those changes over
to OOSMOS, LLC.
- An open source GPLv2 license for the open source community.
Many different terms are used for this kind of license, namely, restrictive, viral,
reciprocal and copyleft.
- A commercial license that supersedes the GPL license allowing
companies to integrate
into their commercial products and distribute them without the GPL restrictions.
This type of license is called a permissive license.

Dirk Riehle's paper
