PopulationDataServiceDesignNotes

The service API will reuse the GIPSEService developed for PHGrid with some modifications.

The service will use the 8/31 gipse schema that includes a filter field to filter the query by data source. This additional element is added to support the rapid recruitment of H1N1 data sources.

The service will provide two operations:

QueryMetadata - returns descriptive metadata for service characteristics and allowed stratifiers

QueryGIPSE - allows querying by the following stratifiers:

• Indicator (EDVisits-Low Temp, EDVisits-High Temp, EDVisits-Unknown Temp, ILI-b-Low Temp, ILI-b-High Temp, ILI-b-Unknown Temp, ILI-n-Low Temp, ILI-n-High Temp, ILI-n-Unknown Temp)
• Region (zip3)
• Age Group
• Disposition/ServiceArea

QueryGIPSE will return counts. Ratios can be determined by dividing the count of the syndrome by the EDVisits.
