10 years ago I tweaked the schema a bit to fix id references and make sure an id is declared before it is referenced.
var statement = {
"id" : "fd41c918-b88b-4b20-a0a5-a4c32391aaa0",
"actor" : {
"objectType" : "Blowup",
"name" : "Project Tin Can API",
"mbox" : "mailto:user@example.com"
},
"verb" : {
"id" : "http://adlnet.gov/expapi/verbs/created",
"display" : {
"en-US" : "created"
}
},
"object" : {
"id" : "http://example.adlnet.gov/xapi/example/simplestatement",
"definition" : {
"name" : {
"en-US" : "simple statement"
},
"description" : {
"en-US" : "A simple Experience API statement. Note that the LRS does not need to have any prior information about the Actor (learner), the verb, or the Activity/object."
}
}
}
};

I was trying to validate an instance against the tincan.schema.json schema. My instance is:
The tool reports valid even though the actor.objectType is not a valid value according to the schema.
