The LAT suite covers the set of software tools that are being developed by the development group at the MPI for Psycholinguistics. This note describes the LAT deployment package (LAT-DP) that allows interested users to install the LAT suite on their servers.

The deployment package covers the following components:

• IMDI metadata framework (browsing, searching)
• LAMUS and AMS2 (archive and access managing system)
• ANNEX annotation viewer including Flash Pseudo Streaming server
• TROVA annotation search tool
• IMEX image viewer

The LAT deployment package

• is ideal for testing or giving presentations
• comes with low system requirements and a manageable download size.
• is based on an custom made embedded Linux with an Apache web server,
• includes a Postgresql database server, an Openldap server and Apache Tomcat instances containing the MPI for Psycholinguistics built language tools all wrapped up in a VMware image

System requirements for running the LAT suite:

• A system capable of running Vmware Player, Vmware Server, Esx Server 3 or Vmware Fusion with at least 512 Mb of free memory for the demoserver guest image and 1 GB of free disk space.

Installation Manual:

• Download the demoserver.zip file: http://www.mpi.nl/tools/latserver/demoserver.zip (299MB)
• Unzip the file in the folder where you want to store your virtual machines.
• Start the Vmware console (or similar) and choose “open virtual machine”, browse to the demoserver.vmx file in the demoserver folder, and boot the machine.
• When finished booting take the assigned guest ipaddress as shown in the guest startup screen and add the following line to the host-machine's hosts file:
  • “<ipaddress of guest> demoserver.gov.is demoserver”
    (in windows c:\windows\system32\drivers\etc\hosts, on unix /etc/hosts)
• You can now use your browser to reach the lat server: http://demoserver.gov.is Or for LAMUS: http://demoserver.gov.is/jkc/lamus
• Initial corpman password for both the lat applications as the Linux corpman user is “demo”.
• When superuser access is needed on Linux the root password is “demoserver”.

Version2 will also contain the OAI PMH metadata gateway.

This distribution can also be adapted for use in a production environment with some adaptations;
adding more disk space for a big corpus and database, changing the host and domain name to something appropriate for your site by using DNS-servers and using bridged networking for direct access to the lat server on the entire network.
In case that using VMWare is not an option for your site, then a native installation directly on Linux is required. Such an installation is much dependent on configuration parameters so that an interaction with Tobias van Valkenhoef is recommended.
