Dear colleagues,

we are glad to announce the release of Cowl v. 0.2.0, a lightweight C API for working with OWL 2 ontologies, developed by SisInf Lab at the Polytechnic University of Bari, and distributed under the Eclipse Public License (EPL) v. 2.0.

Github repository: https://github.com/sisinflab-swot/cowl

Documentation: http://sisinflab.poliba.it/swottools/cowl/howto/index.html

Cowl is a complete implementation of the OWL 2 specification. As of now, it allows parsing OWL 2 ontologies and querying them for axioms and other constructs.

Cowl is designed to be lightweight and portable, so:

- it is written in standard C11 with no compiler-specific extensions and no platform-specific API calls;

- it is completely self-contained, with no external dependencies other than Vector(T) and uHash (which are also self-contained);

- it strives to have a tiny memory footprint while being very fast, meaning it can run even on very resource-constrained devices.

Please help us understand your needs by answering this anonymous survey: https://docs.google.com/forms/d/1GkQyvADFVRzMhnnKACk65v-b3oAboHMbWkoUDq9LN-0

We look forward to hearing about your projects and experiences with Cowl, as well as your suggestions, bug reports and feature requests. And don't hesitate to contact us if you want to work with us on Cowl or related ideas.

Thanks for your attention and cooperation.
