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 experiences issues in both storing and displaying data when the VisualEditor extension is also in use on the wiki.
 * Although Cargo in theory supports the MySQL, PostgreSQL, MS SQL Server, Oracle and SQLite database systems, in practice only MySQL and PostgreSQL have been tested; it is likely that there are bugs in the handling of one or more of the other systems.

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.
