Designing the Microblog Media Type

The aim of this example is to illustrate the process of designing hypermedia types using HTML5 as the base format. Unlike the previous examples, which were based on XML and JSON (both formats devoid of native hypermedia controls), this example starts with a format that already supports basic hypermedia factors.

Starting with HTML5 provides both advantages and drawbacks when designing a hypermedia solution. The good news is the details of document design (which elements are valid, etc.), the specific hypermedia controls, and the method of expressing state transitions are already decided. This means designers do not need to worry about how to define and document much of the hypermedia type. However, with so many details already decided, there is less room for expressing the problem domain in ways clients can easily understand.

This duality of well-defined hypermedia controls and a limit on the options for expressing the problem domain is the key challenge behind working with existing hypermedia types and is, in part, the reason so few new APIs use HTML5 as the base. For many, it seems easier to start from zero using a non-hypermedia type such as XML or JSON and create all of the details from the beginning. But sometimes this option is not available to designers. Instead, designers often must be sure their implementations work well with existing clients (e.g. web browsers) with little or no support from custom scripting or other client-side plug-ins.
