<A HREF="http://news.yahoo.com/s/zd/20060315/tc_zd/173570">What comes after open-source software?</A> Open services, said Sun Microsystems Executive Vice President and Chief Technology Officer Greg Papadopoulos. Open services provide freedom for service developers and represent a place where open-source-based services can be shared and executed, Papadopoulos said. In an open services development scenario, developers work on common patterns for service levels and management, he said. And developers will "not just publish code but prototypical services, too," he added.
