public @interface Tag

This object represents a tag. A tag is meta-information you can use to help organize your API end-points and it can appear in two contexts.

Define tag objects on a method that implements an operation or on a class that contains operations. They will be gathered and stored in the root object of the OpenAPI document.

If the tag annotation definition is associated with a method that corresponds to an operation then the tag name will be added to the OpenAPI document and also be added to the operation tags.

Reference to a Tag can be created by setting the 'ref' attribute.

If the Tag annotation is specified on a class then each operation in the class will inherit the tag unless the operation specifies Tag(s). An operation can specify an empty Tag to not to be associated with any tag(s) inherited from the class.

This annotation is Repeatable.

If more than one tag is defined with the same name then only one tag with that name will appear in the OpenAPI document and the results are implementation dependent.

Note: If both Tag and Tags annotations are specified on the same method or class, then both tag definitions should be applied.

 @Tag(name = "luggage", description = "Operations related to luggage handling.")
 @GET
 public Location getLuggage(LuggageID id) {
     return getLuggageLocation(id);
 }
 

 @Tag(ref = "Bookings")
 @GET
 public Location getBookings() {
     return Response.ok().entity(bookings.values()).build();
 }
