An essential problem in need of a fresh look

Services and the Semantic Web: it's complicated.

The Semantic Web's relationship with services has been a long and complicated one. Many of the early service description efforts had a solid theoretical foundation, yet failed to find broad adoption.
The Web changed a lot since then, and so did the mindset of its researchers.

Today, resource-oriented APIs or “REST APIs” are on the rise – and herein truly lies an important opportunity for the Semantic Web. Services no longer have to exist on a separate island, because the Semantic Web shares with these REST APIs the most essential feature of the Web: resources.

What is our answer, as a community, to this evolution?

With this workshop, we aim to discover new ways to embrace the opportunities that resource-oriented APIs offer to the Semantic Web. We want to challenge researchers to think out of the current box through both paper submissions and interactive on-site discussion and dialog.

Can links do for APIs what they did for the Semantic Web?

The Linked Data movement has provided the Semantic Web with a powerful injection thanks to the power of links. Since REST APIs also center around resources, key questions for the workshop are: How can we enable Linked APIs? And how can they create added value for the Semantic Web?

We look forward to submissions that tackle these and related important questions, by focusing on the specific nature of resource-oriented APIs, the functionality they bring, and their path to integration.
We also actively invite participants to discuss and challenge new ideas.

Workshop description and motivation

The notion of Web services has been around since the beginning of the Web. When the Semantic Web community started evolving, it thus came as no surprise that people had the desire to work on the bridge between services and semantics, especially given the importance of services in various agent scenarios for the Semantic Web. Since SOAP and WSDL were the predominant service technologies at that time, researchers worked on describing their low-level technical details – such as parameters and exception handling – in semantic models, notably OWL-S and WSMO.

When SOAP and WSDL turned out not to be a satisfying answer for a resource-oriented Web, providers shifted from Web services to resource-oriented APIs, commonly called REST or RESTful. In response, researchers ported the concept of describing low-level details to this new situation, giving rise to WADL, MicroWSMO, and others.
However, the ideas themselves were not questioned: can technical descriptions alone satisfy the vision and aspirations of the Semantic Web? New paradigms do not only demand new answers, but – more importantly – new questions.

The questions we look for can be found in different sources.
One of them is the initial Semantic Web vision: what are the missing links to construct a Web for agents, given the Linked Data cloud and resource-oriented APIs? Another source stems from concrete business situations and needs: what do current resource-oriented APIs lack on a semantic level, and how can we provide this?
Clearly, these questions convey fundamental problems that have been neglected for too long.
