License & Terms for Jomres

Jomres is released under two licenses

I want you to use Jomres, and I don't want you to be limited by the type of license, therefore Jomres is released under both the GPL and MIT licenses.

Why the GPL license, which is famously restrictive?

To get maximum exposure, Jomres is listed on both the Joomla and WordPress extension directories. One of the conditions of being listed on those directories is that the software be released under the GPL license.

Why the MIT license?

The MIT license, normally used for libraries, is generally considered to be the most business friendly license, in this context. Many businesses do not allow use of GPL software as a part of their portfolios, but they do allow use of MIT licensed software. If you're using Jomres, you are free to choose which of these two licenses you want to be bound by.

vince picDeveloped and maintained by Vince Wooll, Jomres was initially conceived in early 2005 as a Mambo based solution to a client’s hotel management needs. While it wasn't originally expected to be an online booking system it quickly morphed into one as users requested more and more features.

As the number of feature requests grew Vince knew that he would need to dedicate more time to the project and in July 2005 Jomres was released as a commercial project. Since then Jomres has become the world's oldest online booking plugin for any PHP CMS. It has been used in Joomla 1.0, 1.5, 2.5, 3 & 4 and WordPress 4, 5 & 6.

Aladar joined the project in 2010 after using Jomres for his own projects. He was active on the forum, helping other members of the community and eventually Vince invited him to join the team. Between 2010 and 2018 he was an integral part of the project and made many significant contributions.

Whilst not formally part of the Jomres project, Rodrigo Rocco and Vince have become firm friends. Rod is a freelancer who specialises in doing custom work for Jomres users and developing custom plugins for the system that take advantage of it's modular design. He has built many useful extensions including his fabulous Valentina Template Override Package.
