Should S3I Directory data model also express security scheme?
Metadata is also supposed to describe the configuration of a security mechanism. Although the main mechanism used in the S3I is OAuth 2.0 and the required URLs should be documented somewhere else, we should also include this information in the directory data model, like what WoT also did [1]. So far, I modeled PKIScheme and APIKeyScheme as well, because they are currently being used or will be used for some S3I communication use cases, like encrypted S3I-B messages and LoRa packages.
