Key Concepts and Principles in Service Oriented Computing

In essence, "Web services" technology was the descendant of RPC taking the places of CORBA and DCOM as the solution for software interoperability.

REST and Service

Roy Fielding (2000) proposed the concept of Representational State Transfer (REST) to describe an architectural style of networked systems. He explained - “Representational State Transfer is intended to evoke an image of how a well-designed Web application behaves: a network of web pages (a virtual state-machine), where the user progresses through an application by selecting links (state transitions), resulting in the next page (representing the next state of the application) being transferred to the user and rendered for their use.” In science, REST is about Web application or Web page, according to Roy’s dissertation. REST "service" is invoked using HTTP GET|POST methods and thus may not have much relevance to software engineering.

OGC Web Services (OWS)

Traditionally, OGC generated a variety of standards to enable data interoperability. Except Web Processing Services (WPS), most OWS specifications are about data and map, such as WMS, WFS, WCS, and so on. OWS are mostly REST services developed for online GIS application, not for software engineering.
