Thankfully, as the popular press tries to make anything that is a combination of two things a "mashup," the trend is actually now toward building enterprise-class services to create enterprise-class mashups. The litany of companies (new and old) we talked to at the recent Mashup Camp in Mountain View, Calif., was a respite from the Map + Something Else mentality of the early mashup days.Let's start with WSO2, the erstwhile open source SOA company, which has added an open source Mashup Server to its lineup. Using simple JavaScript, mashup director Jonathan Marsh told us, you can take advantage of this Apache-license software to compose Web services that yank data from the Internet and deliver it as output or as a service to other programs.

This one's a bit of a stretch for the enterprise, but then what industry (or company) doesn't have or attend events? Eventful is a master search site for any and all events, scraping data from more than 2,000 sites and exposing its APIs so you can add events to your own site and calendar. It's actually also a pretty cool Web 2.0 tool in that you can network with friends about an event, or even create demand for an event or performer. The company told us that performers even use its "eventful demand" feature to find out where they should go next. User-generated touring, they call it.

I mistakenly stopped paying attention to most of AOL years ago, but it's been busy, or so the director of AOL's Developer Network, Naveed Anwar, told me. Between Open AIM, its Truveo video search platform APIs (which we are attempting to use ourselves), and Open Mobile, there's plenty for smaller startups to like. AOL was at Mashup Camp (alongside Yahoo ... which at least gave me a shirt!) reminding these mashup developers about all its great services.

Final one for today: We had a little fun with some attendees from Cal State University, Chico (yes, it's a real school). These guys run a series of user groups, including one on Flex and they were at the conference looking for speakers for an upcoming (and Adobe-sponsored) Flex Camp. These guys are great.
