TTTBot creates and updates tables with information about software products in the OpenStreetMap wiki using data from Software2 templates. The bot is operated by User:Tordanik and runs on the FOSSGIS development server.
How to ...
... edit information about software?
Do not edit the tables directly - TTTBot will inevitably overwrite your edits the next day. Instead, update the information on the software's description page. For each OSM-related program, there usually exists a page on this wiki that has the program's name as its title and contains an infobox template (called "Software2"). This template is where TTTBot extracts the information for the tables from, and this is what you should edit.
A lot of information from the template won't even show up in the infobox itself, by the way, but it is still available for tables. To find out what the parameters of the template mean, have a look at Template:Software2.
... add new software to the tables?
If there is no page about the program yet, or that page contains no "Software2" template, then TTTBot cannot know about that program. In this case, you should create the page or add the template to the existing page.
It is possible that a program does't show up in a table even if it has a "Software2" template. That's usually because the software doesn't match the filter criteria of the table, defined by the "SoftwareTable" template. For example, Windows-only software (or software incorrectly categorized as Windows-only in the "Software2" template on its page) will not appear in a table of Linux applications.
... edit entire tables or add new tables?
If you want TTTBot to create a table somewhere in this wiki, place the template "SoftwareTable" there and wait for the next bot run. Similarly, if you want to change the columns of a table, or the selection of software that is supposed to show up in a table, you need to find the existing SoftwareTable template on the page and modify its parameters.
