All LAMS tools must have a known signature. This signature will be used to ensure that jar file names do not conflict.
The signature will have the following format:
mm: is a two letter code denoting the maker of the tool
tttt: is a two to four letter code denoting the name of the tool
vv: is a two digit code indicating the major and minor version of the tool
For example, the survey tool produced by lams has a signature of lasurv10. The "la" indicates that it was developed by the main LAMS team, "surv" stands for "survey" and "10" indicates that it is version 1.0.
We are trying the ensure these codes are unique to each person/company/institution/etc but if we need to double up it won't be fatal as it is the combination of "mmtttt" that needs to be unique. LAMS doesn't split up the tool signature into its parts and assign them any meaning so if we start running out of codes we can switch to "mmmttt".
The tool's tables in the database should be named tl_<signature><rest of name>. For example, a survey tool table is tl_lasurv10_survey_content. _The signature is kept short to allow the <rest of the name> to be meaningful and yet be compatible with databases that allow 32 character tablenames. See Database Conventions and Datasources for more information.
The jar and war files for the tool must also use the signature. So the jar and war files for the survey tool are lasurv10.jar and lasurv10.war.
Existing Tool Signatures
Developed by the core LAMS team. They are "11" for 1.1 - LAMS 2.0 was originally going to be LAMS 1.1 and we had already determined the signatures when we changed the version to 2.0.
Example tool used as starting point for new tools. Not included as an usable tool in production.

Date Based Tool Version
When you create your tool entry, you find you also need to supply a version in the format YYYYMMDD. This is used for installation scripts to update your database and by the import/export logic to convert any old export files to a version compatible with the "current" version of your tool.
It is very important that you stick to this format for the lams_tool.tool_version column. LAMS will work initially if you use a different format, but there will be problems for your users in the future when you produce a new version. We would like to think your tool will be so popular that you will want to bring out new features for your tool and hence new versions.
This version does not have to match the vv in the tool signature. The vv in the tool signature should match something meaningful for your users.
