RFC 9880 and the IoT Validation Problem: From Standards Fragmentation to a Device-Model Compiler The Internet of Things has a data-model problem that no amount of protocol engineering can fix. RFC 9880's Semantic Definition Format offers a way out — but only if we treat it as a language to compile, for data validation, not only as a document to read.
