The EPSG database can be downloaded from <A HREF="http://www.epsg.org">http://www.epsg.org</A>. The SQL scripts (modified for the HSQL syntax as <A HREF="doc-files/HSQL.html">explained here</A>) are bundled into this plugin. The database version is given in the edition attribute of the authority. The HSQL database is read only. <P> <H3>Implementation note</H3> The SQL scripts are executed the first time a connection is required. The database is then created as cached tables ( and files) in a temporary directory. Future connections to the EPSG database while reuse the cached tables, if available. Otherwise, the scripts will be executed again in order to recreate them. <p> If the EPSG database should be created in a different directory (or already exists in that directory), this directory can be specified in two ways: <p> <ul> <li>It may be given explicitly as an argument to the <A
