On the 10th February, speaker Martin Ledvinka presented the topic of how to give semantics to Web Services using JSON-LD. The whole session was recorded.
REST is nowadays the most popular architecture for building Web services. However, data produced by REST Web services assume their consumers have prior knowledge of their structure and meaning.
JSON-LD is a lightweight data format that can be used to provide easily accessible context in a backwards-compatible way.
This talk discussed the options of using JSON-LD to enhance REST Web service output with contextual information without requiring significant development costs on either server and client side.
In a Java application, one can use JB4JSON-LD - a library allowing to easily serialize and deserialize POJOs to JSON-LD.
