In order for automation scripts to produce content inside a working copy of &TCAR;, it is required that all work lines be related somehow. The automation scripts take the relation between work lines as reference to determine the place the information they will work with will be retrieve from (e.g., scalable vector graphics, documentation, translations, etc.), as well as the place where it will store the final files produced as result of automation process (e.g., portable network graphics, documentation ready for printing and reading online, etc.). In order to implement the relation between work lines it is required to establish a path name convenction, so we can conceptually organize different components and relate them one another using predictable path constructions in a scalable way. Based on this need, we identify three different path types inside &TCAR;. These path types are: Output Paths, Input Paths, and Auxiliary Paths.

The output paths point to directories inside the working copy which contain files produced from files inside the input paths. For example, the following paths are consider as output paths: trunk/Identity/Images/Brands/ trunk/Documentation/Manuals/Tcar-ug/ trunk/Identity/Images/Themes/Modern/2/Distro/5/Anaconda/ Output paths are also known as Render-able Directories because they are the type of path you should provide as argument to functionality so as to produce content through it.

The input paths point to a directories inside the working copy which contain files used to produce files inside output paths. For example, the following paths are considered as input paths: trunk/Identity/Models/Brands/ trunk/Documentation/Models/Tcar-ug/ trunk/Identity/Models/Themes/Default/Distro/5/Anaconda/

The auxiliary paths point to directories inside the working copy which contain files used to create modified instances of inside input paths which are use in turn to produce files inside output paths. For example, the following paths are considered as auxiliary paths: trunk/Identity/Images/Brands/ trunk/Locales/Documentation/Models/Docbook/Tcar-ug/es_ES/ trunk/Locales/Identity/Models/Themes/Default/Distro/5/Anaconda/es_ES/ The relationship between input, output and auxiliary paths is created by combining the second directory level of input paths with the second directory level in the repository directory layout. In the repository directory layout, the second level includes the trunk/Identity, trunk/Documentation and trunk/Scripts directories. These directories are always used to create input and output paths. The trunk/Locales directory, on the other hand, is always used to create auxiliary paths only for input paths available under Identity, Documentation and Scripts directories. For example, if the LANG environment variable is set to es_ES.UTF-8 and you execute the functionality of centos-art.sh script with the trunk/Documentation/Manuals/Docbook/Tcar-ug/ input path as argument, it will produce &TCARUG; in Spanish language using translation messages from trunk/Locales/Documentation/Models/Docbook/Tcar-ug/es_ES/ auxiliary path and would save final documentation files under trunk/Documentation/Manuals/Docbook/Tcar-ug/es_ES/ output path.
