Abstract: Various disclosed embodiments include methods and systems for determining whether representational state transfer (REST) application programming interfaces (APIs) are compatible. A method is performed by a processing system that includes a processor. The method comprises obtaining a first REST Chart describing a first version of a REST API and obtaining a second REST Chart describing a second version of a REST API. The method comprises determining whether the first version and the second version are compatible using the first REST Chart and the second REST Chart by determining whether a compatible path exists between the first REST Chart and the second REST Chart.

Abstract: A high frequency connector comprises a connector body and metal conductive wires. An embedding groove is installed on the longitudinal wall of the connector body. An embedding block is installed with respect to the embedded groove; and the embedded block has a plurality of through holes. The metal conductive wire includes a first conductive wire and a second conductive wire. The fixing end of the second conductive wire is inserted to the through hole of the embedding block, and a bent portion in the middle section of the second conductive wire resists against the lower surface of the embedded groove. As a consequence, a high frequency connector for transferring high frequency signals is constructed.
