The latest version of Mulgara can always be found on the main Download page. If you require an older version, then these can be found in the appropriate directory found in the general downloads directory.
If you just want to run Mulgara, then download either the mulgara-*-bin.zip or mulgara-*-bin.gz files according to which is the more convenient format (the * refers to the version number of the files). This file expands to:
mulgara-*/ mulgara-*/dist/ mulgara-*/dist/querylang-*.jar mulgara-*/dist/mulgara-*.jar
These files are also present in the mulgara-*-bin-all.gz and mulgara-*-bin-all.zip files, along with all of the source and configuration files required to build the system.
The mulgara-*.jar file contains the standalone Mulgara server. The querylang-*.jar file contains all the client code.
