## Notes

OpenACS is a toolkit for building community-oriented web applications, written in Tcl and published on GitHub under the GNU General Public License. The core packages live in the [openacs-core repository](https://github.com/openacs/openacs-core), whose install notes name Oracle or PostgreSQL as the database. The OpenACS community maintains the software.

It runs as a server process that a keepalive mechanism restarts when it halts, and it carries internationalization and localization for the user interface.

## Worth knowing

The project's own website, openacs.org, did not answer when this record was checked, so the record has no homepage link and is listed as a stub until the site responds again.
