Do you have a .NET Passport identity? You may not realize it, but chances are reasonably high that you do. If you have a HotMail or MSN account, Microsoft assigned a Passport identity to you automatically. Microsoft claims to have more than 160 million users registered in the Passport identity service. Pretty soon you'll need a Passport ID to have any interaction with Microsoft. In December 2001, quite a few gamesters were surprised to discover that their old accounts at the Microsoft Zone gaming site wouldn't work without a Passport ID. Microsoft also requires a Passport ID to join MSDN, to register for a Microsoft seminar, or to access Microsoft's node in the UDDI public registry. The new Windows XP Product Activation (WPA) system uses Passport by default. You can also use your Passport ID to log in to your XP system. So just what does a Passport identity do for you... (more)

The Secret Sauce

How do you define a Web service? If you ask five people to give you a definition, you'll probably get at least six answers. Is a Web service any application that can be accessed over the Web, or is it limited to applications that expose a programmatic interface? Is it the code that implements the service or the interface to the code? Do you have to use SOAP? What about XML-RPC? Or RosettaNet? Or FIXML? Or some other XML protocol? And do you have to use XML? Does SWIFT qualify as a Web service? I know that many people will disagree with me, but my basic definition is as follows: ... (more)

Infrastructure-Level Web Services

When discussing Web services, most people tend to focus on the core Web services framework (the standards and protocols) and the applications that you can build with the framework. Although I have no trouble waxing profusely on these topics, I get even more jazzed when I start to think about infrastructure-level Web services. (I know. I need to get a life.) Infrastructure-level Web services are Web services that implement part of the distributed computing infrastructure. They help other Web services communicate. In particular, these services make the Web services framework more ... (more)

The State of Standards

There is an old saying among standards wonks: "The most wonderful thing about standards is that there are so many of them." And this truism is more applicable today than ever before. There are so many WS-* specifications, I've started referring to them as WS-Vertigo. But there is a reason that there are so many of them. The Web Services Framework (WSF) relies on a composable architecture. One of the primary tenets of the WSF is to keep things as simple as possible. Therefore, if an application doesn't require security, reliability, or transactions, you shouldn't clutter up the i... (more)

Registering a Web Service in UDDI

UDDI (Universal Description, Discovery and Integration) is a registry for Web services. It provides a mechanism to advertise and discover Web services. Although you don't need to use UDDI to implement a Web services solution, you'll find that a UDDI registry greatly simplifies the management and administration of your services, particularly once they have reached a certain critical mass. Once you've developed more than a few services, and once you start giving access to those services to more than a few controlled individuals, management starts to get more challenging. Potential...
