1. Metadata files updates
The metadata file format is in a transition period.
Both 2.2 and 2.3 format versions are valid.
The metadata format version 2.3 is described in the User’s manual.
The purpose of the 2.3 is to handle the float deployment and mission information, in particular for floats that have multiple and changing configurations.
The format version 2.3 configuration parameters section is similar to technical parameter format 2.3 :
It handles an “unlimited” but standardized number of configuration parameters

2. 2.5.4 Configuration parameters
char CONFIGURATON_PARAMETER_NAME(N_CONF_PARAM, STRING128)
Name of the configuration parameter.
Example : “CONFIG_ParkPressure_dBAR”
char CONFIGURATON_PARAMETER_VALUE(N_CONF_PARAM, STRING128)
Value of the configuration parameter.
Example : "1500"
int CONFIGURATON_PHASE_NUMBER(N_CONF_PARAM)
Phase number of the configuration parameter.
Example : 0
int CONFIGURATION_PHASE_REPETITION(N_CONF_PARAM)
Number of cycle repetition for this phase.
Example : 99999

3. Floats with multiple configurations
For the basic configuration where all the cycles are programmed to be the same :
CONFIGURATION_PHASE_NUMBER is set to 0
CONFIGURATION_PHASE_REPETITION is set to 99999
For a float with changing configuration :
CONFIGURATION_PHASE_NUMBER is used to describe a phase
CONFIGURATION_PHASE_REPETITION is used for the number of consecutive cycles configured in a given phase.

4. Floats with multiple configurations
Example 1: a float is programmed to perform regularly 4 cycles with 400 decibar profiles and the 5th cycle with a 2000 decibar profile.
CONFIGURATION_PARAMETER_NAME = “CONFIG_ParkPressure_dBAR”
CONFIGURATION_PARAMETER_VALUE = "400"
CONFIGURATION_PHASE_NUMBER = 0
CONFIGURATION_PHASE_REPETITION = 4
CONFIGURATION_PARAMETER_VALUE = "2000"
CONFIGURATION_PHASE_REPETITION = 1

5. Floats with multiple configurations
Example 2: a float is configured with telemetry. The float operator randomly changes the park pressure to : 200, 400, 1500 decibars
CONFIGURATION_PARAMETER_NAME = “PRES_ParkPressure_dBAR”
CONFIGURATION_PARAMETER_VALUE = "200"
CONFIGURATION_PHASE_NUMBER PHASE_NUMBER = 0
CONFIGURATION_PHASE_REPETITION REPETITION_RATE = 1
CONFIGURATION_PARAMETER_VALUE = "400"
CONFIGURATION_PHASE_NUMBER PHASE_NUMBER = 1
CONFIGURATION_PARAMETER_VALUE = "1500"
CONFIGURATION_PHASE_NUMBER PHASE_NUMBER = 2
CONFIGURATION_PHASE_REPETITION REPETITION_RATE = 99999
The repetition rate of CONFIGURATION_PHASE_NUMBER PHASE_NUMBER 3 is 99999, the fill value. It means that the float will keep this configuration with a parking pressure equals to 1500 decibars.
