and Wilde, Erik From SOA to REST Tutorial: Introduction.
This introduction presents the schedule, the tutorial presenters, and some background for the tutorial. Specifically, we briefly mention all the *OA terms that have been invented in recent years, such as SOA (Services), ROA (Resources), WOA (Web), SynOA (Syndication), and EOA (Event), and briefly set them into context. Our main goal is to explain our notion of SOA for the purpose of this tutorial, and what we perceive as the core tasks when moving from SOA to REST.
Wilde, Erik REST in Practice.
REST's level of abstraction and its simplicity as a small set of constraints can make it hard to get a grasp on how it can be applied for real-worl projects. This presentations introduces real-world REST by looking at how REST ce be used by reusing existing RESTful designs in terms of representations and interaction protocols; Atom and the Atom Publishing Protocol (AtomPub) are used as examples for existing RESTful designs. In addition, we take a brief look at how to go beyond using these canned REST approaches, and how existing programming framework provide support for designing and implementing RESTful services.
Pautasso, Cesare REST vs. WS-* Comparison.
In this part we summarize the WS-* vs. REST debate by giving a quantitative technical comparison based on architectural principles and decisions. We show that the two approaches differ in the number of architectural decisions that must be made and in the number of available alternatives. This discrepancy between freedom-from-choice and freedom-of-choice explains the complexity difference perceived. However, we also show that there are significant differences in the consequences of certain decisions in terms of resulting development and maintenance costs. The comparison helps technical decision makers to assess the two technologies more objectively and select the one that best fits their needs: REST is well suited for basic, ad hoc integration scenarios, WS-* is more flexible and addresses advanced quality of service requirements commonly occurring in enterprise computing.
Pautasso, Cesare RESTful Service Design.
REST is simple to define, but understanding how to apply it to design RESTful services is more difficult. The goal of this part of the tutorial is to present the main design elements of a RESTful architecture and introduce a design methodology for RESTful services. A selection of useful patterns and anti-patterns will be discussed with some examples that will be further developed in the practical part.
Wilde, Erik What is REST?
Representational State Transfer (REST) is defined as an architectural style, which means that it is not a concrete systems architecture, but instead a set of constraints that are applied when designing a systems architecture. We briefly discuss these constraints, but then focus on explaining how the Web is one such systems architecture that implements REST. In particular, the mechanisms of the Uniform Resource Identifiers (URIs), the Hypertext Transfer Protocol (HTTP), media types, and markup languages such as the Hypertext Markup Language (HTML) and the Extensible Markup Language (XML). We also introduce Atom and the Atom Publishing Protocol (AtomPub) as two established ways on how RESTful services are already provided and used on today's Web.
About this site
This website has been set up for WWW2009 by Christopher Gutteridge of the University of Southampton, using our EPrints software.
We (Southampton EPrints Project) intend to preserve the files and HTML pages of this site for many years, however we will turn it into flat files for long term preservation. This means that at some point in the months after the conference the search, metadata-export, JSON interface, OAI etc. will be disabled as we "fossilize" the site. Please plan accordingly. Feel free to ask nicely for us to keep the dynamic site online longer if there's a rally good (or cool) use for it... [this has now happened, this site is now static]
