What Is an Information Architect?

What is my actual job? I don't have a great name for it, and neither does anyone else. I sometimes used to call myself a business analyst. One definition of that job, from the International Institute of Business Analysis (www.iiba.org) is:

A business analyst works as a liaison among stakeholders to elicit, analyze, communicate and validate requirements for changes to business processes, policies and information systems. The business analyst understands business problems and opportunities in the context of the requirements, and recommends solutions that enable the organization to achieve its goals.

Okay, that does cover quite a lot of what I do, but my job is a bit more specific than that because I work specifically on SharePoint projects. Also, I do more than “recommend” solutions; I design and build stuff as well.
