- ### Items

  - #### name

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Short name of the mapping. Used for debugging purposes.

  - #### description

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### documentation

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Technical documentation for a particular object or construct.

    The purpose of this element is to document system configuration and behavior. The documentation will not be presented to end users. In fact, it will probably not be presented at all in midPoint user interface. This documentation element is supposed to be a part of the technical documentation of midPoint deployment. The tools than generate deployment configuration will look for these elements and combine them to compiled documentation document.

    AsciiDoc formatting is assumed for this element. Any leading or trailing whitespace is skipped. Indentation equivalent to he indentation of the first non-blank line of text is also skipped.

  - #### extension

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Place for non-standard object properties. The elements placed here will be handled exactly like the elements in the object body. It must NOT contain standard elements.

  - #### trace

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Explicitly trace the execution of this mapping. The execution will be logged on INFO level if this property is set to true to make sure that it will be visible in the logs.

  - #### authoritative

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Authoritative flag controls the way how mapping is used to remove values. It does not influence adding of values. If mapping is authoritative then it will add value and also remove the value. If mapping is not authoritative it will only add the value.

    Non-authoritative mappings are used if there are several possible sources for a particular value. E.g. the value may be added by the mapping and also added directly on the resource by system administrator. In this case midPoint cannot remove the value when the assignment (or role) containing the mapping is removed because the value might have been added manually. Other settings, such as tolerance may apply on attribute level.

    The default value for authoritative flag is true.

  - #### exclusive

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Exclusive mapping may be applied only as a single mapping for a particular target property. If an exclusive mapping is applied together with any other mapping it results in an error.

    The default value for exclusive flag is false.

  - #### strength

    Flags: RAM,runtime,AVals:3

    Multiplicity: [0,1]

    Strength of the mapping defines how aggressively will the mapping be applied. The strongest mappings are applied all the time (regardless of the consequences) and the weakest mappings are applied only if nothing else can be applied.

  - #### channel

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Limits application of this mapping only to specific channel. If the channel is listed then the mapping will be applied. If it is not then it will not be applied. If no channel is specified then no limitations apply and the mapping will be applied for all channels.

  - #### exceptChannel

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Limits application of this mapping except for channel specified. If the channel is listed then the mapping will be not applied in this channel. If it is not then it will be applied. If no channel is specified then no limitations apply and the mapping will be applied for all channels.

  - #### timeFrom

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### timeTo

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### source

    Flags: RAM,runtime

    Multiplicity: [0,-1]

  - #### expression

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### target

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### condition

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### scope

    Flags: RAM,runtime,AVals:2

    Multiplicity: [1,1]

    Is this mapping to be used during value transformation, value consolidation, or in both contexts?
