Title: REQUEST PROCESSING IN THE SERVICE LAYER
Abstract:
Methods, systems, and devices may be used to support freshness-based processing of requests. Freshness-based processing may involve the service layer examining the age of stored content (e.g., resource representation) that it hosts and determining whether it is fresh enough to satisfy a retrieve or discovery request with a specified freshness requirement. If not fresh, the service layer can contact an application to refresh the content. In addition, freshness-based processing can also involve the service layer examining the semantic state of a command oriented update request to determine whether its state is fresh or not with respect to prior commands processed by the service layer. For example, the service layer may compare stored content associated with controlling a particular application (e.g. door is locked) and against the semantic content of an update request (e.g., unlock door) to determine whether it is the same (e.g., stale) or not (e.g., fresh). If fresh, the service layer can then re-target the update request to an application to have it perform the command (e.g., unlock door).
