Reference Use Cases
Original list
These are the winners of the vote on the Favorite Use Cases List. As we decided to have 4 use cases as reference (see http://www.w3.org/2009/09/23-SSN-irc#T20-49-25) and 4 were on 4th place (having 3 votes), the one having 3 votes first was selected as No.4; please feel free to comment on this.
| Use Case Class | Responsible | Short Description | Description |
|---|---|---|---|
| Data discovery | Oscar + Kevin | Find all observations that meet certain criteria. The user may use different criteria to select the area and window to be considered in the spatio-temporal constraint. Or the user may select specific types of constraints in terms of the types of observations to be found. | see Use Case Data |
| Device discovery | Holger | Find all the devices that meet certain criteria. The criteria can be something like type, geographic region, measured phenomenon, range of measurement, availability, owner/responsible party, manufacturer etc. and also combinations of those. | see Use Case Device |
| Process/provenance | Laurent | Provide extra information about the instrument to better evaluate or process the data | Use Case Process Provenance |
4th use case
We have found that the ontologies modules required to document and analyse the sensor outputs for provenance management or for the diagnosis of errors/quality control are more centered on the sensor ability to sense than the ones that are require to task or program a sensor or sensor networks where external factors having an impact on the operation of the sensors are important.
So it is important to identify a fourth use case as an important one and document it, even partially.
