Return of the Jedi Blogger with HTML5 and Web Services

It has been a very busy summer and three months have slipped away since my last post. Since then, I’ve been working on other projects and doing some summer time traveling, which included visits to Los Angeles and Las Vegas. I have also been doing some very interesting work with HTML5 and web services. Well, with summer time activities winding down, it’s time to get back to work on the World of Art Web App project. In coming posts, I will be enhancing the server side of the web app, with a new web service, based on Microsoft’s Windows Communication Foundation (WCF). I will also enhance the client, with a new artist page based on the new web standard, HTML5.

My next post will cover the WCF web service. The purpose of the web service, is to listen for requests from various software clients, and respond to the requests with information from the World of Art Web app. The architectural objective in the design of the web service, is not to expose the business logic of the web app to world wide web. Instead, the design objective is to only expose specific data elements and implement a scheme, that enables client applications to access this data, and manipulate it using their own business logic. With these design objectives in mind, I have decided to use the Representational State Transfer (REST) architectural model.

The web service will reuse all of the Entity Framework and the data access layer components already developed. As previously stated, these components will not be exposed by the web service. However, the web service will use the output of these components to satisfy a basic contract for information, as requested by a client application.
