| Expert | Herma van Kranenburg (TELIN) Niels Snoeck (TELIN) Marco Marengo (TILAB) |
| Priority | mandatory |
| Description | The SPICE platform must allow context queries based on the semantic context schema. A context query may include additional parameters such as required "level of confidence". A knowledge source may answer the query only if it matches all these parameters. |
| Rationale | Upon requesting or subscribing to contextual information from a knowledge source, the requesting party should be able to state additional conditions on the information that is to be provided. Conditions could include general quality measures of context information such as cost, accuracy, or precision. Knowledge sources may not be obliged to provide only information that conforms to the stated conditions. |
