Regarding schemas for validation For validating payloads you have more than open-licensed 700 data models with a json schema at the Smart Data Models Program. In the menu option Search you can look for anything in a data model . There is always a file named schema.json which contains the json schema you could use. Anyhow this has to be done externally to the broker.Besides this it is a colalborative program so you can contribute with yours as long as there is an actual use case and you accept to release it with an open license. There are plenty of libraries for schema validation or online services. As far as I know this can be validated externally. I've heard that somebody from the university of cantabria have developed some libraries to validate with NGSIv2 but I guess they could provide you with more info.
