Enterprise Mashups Get Caught in the Web 2.0

Although discussions of the W3C’s Semantic Web project often go deeply into ontologies—the concepts and relationships that describe and represent an area of knowledge—and the use of the Resource Description Framework to model these relationships, there’s no formal requirement for either of these concepts in a mashup. In the cases of both the Semantic Web and a mashup, Uniform Resource Identifiers are used to define the relationships as well as their end points.

To date, many of the mashups one finds use the same model as the initial example: Take some data, add a map, and there’s the mashup. That’s due in part to the relative accessibility of high-quality maps online, thanks to Google, Yahoo and others, and the relative simplicity of displaying data against a map.

The combination of APIs, XML and good old-fashioned screen-scraping can become increasingly complex, but since many Web APIs attempt to be language-agnostic, developers can assume that their choice of tools is likely to be driven more by their own comfort level than by a tool’s compatibility with a given API.

But that’s just the beginning, compared with where some of the Internet’s big players want to go with the mashup model. Whether it’s Microsoft’s focus on communications (see “Microsoft Creates Sandbox for Telco Mashups,” above), or Sun’s blend of entertainment and news at The Big Mashup (www.sun.com/thebigmashup), it’s clear that the Web-as-a-platform is the next big thing.

But for it to be useful in the enterprise, it requires more than just APIs and XML, Bloomberg contends. “The overlap between the Web 2.0 world and the enterprise world is what we call the ‘enterprise mashup.’ What makes them ‘enterprise’ is that the services are loosely coupled; that is, they’re managed, they’re secure, there’s governance in place to deal with…the policies that apply to how organizations use services,” he said.

“Governance is really the key,” Bloomberg continued, “because no enterprise is just going to allow anyone to put any service they want together, however they like, the way you would with Google Maps. In the enterprise, services have sensitive information, and sensitive capabilities. You can’t just take the free-for-all… aspect of Web 2.0 and import it into the enterprise, without thinking through the whole governance question.”
