PART A


1. Evaluator:

Johannes Echterhoff (echterhoff at uni-muenster.de)

EU project OSIRIS - Open architecture for Smart and Interoperable 
networks in Risk management based on In-situ Sensors

2. Submission: OGC 06-028r5, OGC Sensor Alert Service Implementation 
Specification


PART B


1.1. Requirement: improve filtering

right now filtering happens only based upon SensorID OR an EventFilter, 
filtering based upon SensorID AND EventFilter should be made possible

1.2. Implementation Specification Section number: 16

1.3. Criticality: Major

1.4. Comments/justifications for changes:

The schema of the Submit operation allows to only filter based upon 
sensor ID or an event filter (location, offering or value filters). 
Filtering based upon sensor ID AND other criteria should be made possible.



2.1. Requirement: Advertisement profile

define an “Advertisement”-profile for SAS

2.2. Implementation Specification Section number: General

2.3. Criticality: Minor

2.4. Comments/justifications for changes:

An “Advertisement”-profile for SAS should be defined, because 
implementing RenewAdvertisement (for example) without the other 
operations does not make sense



3.1. Requirement: Acknowledgement handling

define default behaviour for what happens if alerts are not acknowledged

3.2. Implementation Specification Section number: General

3.3. Criticality: Major

3.4. Comments/justifications for changes:

At least a default behaviour for handling alerts that are not 
acknowledged should be defined for SAS.
