Extension:Cargo/Known bugs and planned features

Known bugs

 * The buttons in the 'calendar' display format (like "today") currently still have their values hard-coded in English.
 * There is currently no way to query on fields that hold a list of coordinates.
 * If a table is recreated via the web interface and the "job run rate" (set via $wgJobRunRate) is too high, it can lead to some pages not getting their data stored.
 * Cargo has in the past experienced issues in both storing and displaying data when the VisualEditor extension is also in use on the wiki; it is not clear if this still a problem.
 * Cargo is known to work with the MySQL, PostgreSQL and MS SQL Server database systems. It has not been tested with either Oracle or SQLite, and most likely will not work with either one.

Planned features
Features that it would be useful to add to Cargo include:
 * More display formats, including slideshows and more complex charts.
 * Allow for defining "child tables" for templates, so that all templates that show up together on certain pages can be queried and displayed together more easily, especially in Special:Drilldown.
 * Better automatic display of data, including automatic maps, calendars/timelines and bar charts for tables that contain fields of type Coordinates, Date/Datetime and Integer/Float, respectively.
 * Allowing for defining a field's allowed values to be a hierarchy, rather than just a simple list - for use in forms, drilldown and possibly queries (i.e., querying on a field matching some value and getting back the set of pages where the field matches not just that value but its children values).
 * A new "Ratings" field type, which would have special handling in forms and drilldown.
