| name         | String    | Name of this measure                                                                                                                                                                                                                                               |
| column       | String    | Column which is source of this measure's values. If not specified, a measure expression must be specified.                                                                                                                                                         |
| datatype     | String    | The datatype of this measure: String, Numeric, Integer, Boolean, Date, Time or Timestamp. The default datatype of a measure is Integer if the measure's aggregator is *Count*, otherwise it is Numeric.                                                            |
| formatString | String    | Format string with which to format cells of this measure. For more details, see the **mondrian.util.Format** class.                                                                                                                                                |
| aggregator   | String    | Aggregation function. Allowed values are *sum*, *count*, *min*, *max*, *avg*, and *distinct-count*. The *distinct count* value is allowed for backwards compatibility, but is deprecated because XML enumerated attributes in a DTD cannot legally contain spaces. |
| formatter    | String    | Name of a formatter class for the appropriate cell being displayed. The class must implement the **mondrian.olap.CellFormatter** interface.                                                                                                                        |
| caption      | String    | A string being displayed instead of the name. Can be localized from Properties file using **#{propertyname}**.                                                                                                                                                     |
| description  | String    | Description of this measure. Can be localized from Properties file using **#{propertyname}**.                                                                                                                                                                      |
| visible      | Boolean   | Whether this member is visible in the user-interface. Default true.                                                                                                                                                                                                |
