Hi Dimitris, The Orion context broker does not support any schema validation. This means that if this is key to you, you will need to build your on solution for doing that. The problem anyhow would be that synch schema validation introduces latency which is far from ideal in almost real time apps. An idea could be to do validation asynchronously, for example leveraging envoy proxy, you could implement validation on response and log failed validations in a message queue or returned in the response. Data will be injected without delay, and you will be able to get some insight on the validation process. Still, this work easily for post (i.e. full entity validation), implementing the logic for single (or multiple) attribute updates would require some schema manipulation.

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. > > Best > > >> On Mon, 2022-03-14 at 19:56 +0200, Dimitris Kalogeras wrote: >> Hi to all of you, >> >> I am doing a data modeling utilizing NGSIv2 for a specific domain.
