Description

The MariaDB JDBC is compatible with the MySQL JDBC driver. It has different license; the MariaDb JDBC driver is LGPL and the MySQL JDBC driver is GPL with a special FOSS exception.

In addition, the MariaDB JDBC driver response to "jdbc:mysql:..." URLs.

Supporting the driver has two parts:

When MariaDB is explicitly chosen in "sdb:sdbType", we have a registration for "MariaDB" to map to "org.mariadb.jdbc.Driver" and ideally build the right JDBC URL for the case when the URL is not explicitly provided.

The other part is for a setup is for MySQL but only the MariaDB JDBC driver is on the classpath. We can treat this as a special-case during the loading of the JDBC driver so if looking for the MySQL classname ""com.mysql.jdbc.Driver" fails, the code also looks for "org.mariadb.jdbc.Driver".

At no point is Jena (source or binary) shipping either JDBC driver.
