Thing Description Ontology

All Action-based interaction affordance of the Thing.

Defines any data that needs to be passed to cancel a subscription, e.g., a specific message to remove a Webhook

All Event-based interaction affordance of the Thing.

Set of form hypermedia controls that describe how an operation can be performed. Forms are serializations of Protocol Bindings.

Used to define the input data schema of the action.

Offers an affordance to interact with the Thing

Provides Web links to arbitrary resources that relate to the specified Thing Description.

Defines the data schema of the Event instance messages pushed by the Thing.

Used to define the output data schema of the action.

All Property-based interaction affordance of the Thing.

Set of security definition names, chosen from those defined in securityDefinitions. These must all be satisfied for access to resources. Note: multiple values are deprecated. Use a ComboSecurityScheme if necessary.

Defines data that needs to be passed upon subscription, e.g., filters or message format for setting up Webhooks.

Define URI query template variables as collection based on schema specifications. The individual variables DataSchema cannot be an ObjectSchema or an ArraySchema.

Indicates whether the action is idempotent (=true) or not. Informs whether the action can be called repeatedly with the same result, if present, based on the same input.

A hint that indicates whether Servients hosting the Thing and Intermediaries should provide a Protocol Binding that supports the observeproperty and unobserveproperty operations for this Property.

Signals if the action is safe (=true) or not. Used to signal if there is no internal state (cf. resource state) is changed when invoking an Action. In that case responses can be cached as example.

Indexing property to store entity names when serializing them in a JSON-LD @index container.

Define the base URI that is used for all relative URI references throughout a TD document. In TD instances, all relative URIs are resolved relative to the base URI using the algorithm defined in [RFC3986]. base does not affect the URIs used in @context and the IRIs used within Linked Data [LINKED-DATA] graphs that are relevant when semantic processing is applied to TD instances.

Indicates the WoT Profile mechanisms followed by this Thing Description and the corresponding Thing implementation.

Provides a version identicator of this TD instance.

Provides a version indicator of the underlying TM.

Provides information about the TD maintainer as URI scheme (e.g., mailto [[RFC6068]], tel [[RFC3966]], https).

Provides version information.
