6 | * We first query the scheme using the $dao->fields function & then augment | |
7 | * that information by calling the _spec functions that apply to the relevant function | |
8 | * Note that we use 'unique' field names as described in the xml/schema files | |
9 | * for get requests & just field name for create. This is because some get functions | |
10 | * access multiple objects e.g. contact api accesses is_deleted from the activity | |
11 | * table & from the contact table | |

17 | * - function: callback (mixed) | |
18 | * - params: array, varies | |
