A Format and Protocol for Machine-to-Machine OWL Data Streams

Semantic technologies are increasingly adopted in resource-constrained environments such as the Internet of Things (IoT) and sensor networks, yet little attention has been given to encoding formats and protocols for semantic data transmission. This paper introduces ProtocOWL, a compact binary format and lightweight protocol designed for efficient, stream-based Web Ontology Language (OWL) data interchange in resource-constrained and volatile machine-to-machine networks. ProtocOWL supports incremental updates and a novel adaptive memory scheme. Preliminary experiments show that ProtocOWL achieves very high space savings over standard OWL serializations, with significantly faster coding performance, and enables communicating devices to trade off encoding size for resource usage, paving the way for practical semantic interoperability across the Semantic Web of Everything.
