Hypercat standard is a hypermedia catalogue format designed for exposing information about the Internet of Things assets over the web.
Hypercat is an open, lightweight JSON-based hypermedia catalogue format for exposing collections of uniform resource identifiers (URLs) for exposing information about IoT assets over the web. It is extremely simple, described by one participant as "the most that 40 companies could agree on" with a strong security model. Using HTTPS, REST and JSON, each Hypercat catalogue may expose any number of URIs, each with any number of resource description framework-like (RDF-like) triple statements about it. Hypercat allows a server to provide a set of resources to a client, each with a set of semantic annotations. Implementers are free to choose or invent any set of annotations to suit their needs. A set of best practices and tools is currently being developed. Click here to access the Hypercat Wiki and FAQs for further information.
