Requirements
This paragraph should be moved to the requirements documentation.
Interop1 - Transparency in sharing of locally edited data
Verify that it is visible for the user which locally edited data will be shared.
This includes explicitly visualising any removal of central data.
Interop2 - Transparency in sharing from central data
Verify that it is visible for the user which displayed data comes from the shared central source.
This includes explicitly visualising any removal of local data.
Interop3 - Exhaustive data mapping
Verify that all the data from the central source is visible for the user.
Interop4 - Erroneous data mapping
Verify that the user is consulted when incoming data from the central source can not be processed. If possible, the user interaction can't solve this immediately,
Interop5 - Input validation
Verify that the validation of user input is also applied for incoming data from the central source. If the validation fails, the data should be handled as erroneous data.
Interop6 - Transformation design
Verify that your transformation of central data is well-designed and documented. The design includes the restrictions the central data should apply to to be able to serve as input for the transformation.
All data that is not suitable for the transformation should be handled as erroneous data.
Interop7 - Server processing
Verify that the processing of erroneous data on a server (where there is no immediate user interaction) is logged, monitored and eventually presented to the user.
Interop8 - Logging
Verify that enough information about manipulation of central and local data is logged to enable later analysis of possible problems.
