Proposed change affects: AS Imp Spec X Best Practices Paper Other
Title: Enhancement of Connections
Source: University of Muenster, Institute for Geoinformatics (IfGI)
Work item code: Date: 20.10.09
Use one of the following categories:
F (Critical correction)
A (corresponds to a correction in an earlier release)
B (Addition of feature),
C (Functional modification of feature)
D (Editorial modification)
Detailed explanations of the above categories can be found in the TC Policies and Procedures.
Reason for change: The connections in SensorML are insufficient for automatic processing. It only allows one instance of each process or data block. It is not possible to use one process or processChain with different data sources or destinations.
Therefore, the parameterization of 'source' and 'destination' should be extended to specify the desired instance/group.
This attribute (here: ‘group’) should be optional.
Summary of change: Enhances parameterization of ‘source’ and ‘destination’ elements
Consequences if
not approved: No possibility for complex processing /reuse of processes.
