Web 2.0 services: these objects are closer than they appear EDUCAUSE Evolving Technologies Committee Malcolm Brown, Dartmouth College
[email protected] September, 2006 What is it? Web 2.0 services are a very broad range of network-based, cross platform services. This is an area that is expanding rapidly, so rapidly in fact that columnists and bloggers are drawing parallels to the dot com boom. The diversity of these services and their relentless pace of evolution make it challenging to define this evolving technology succinctly. A useful O’Reilly article1 suggests that the “Web 2.0” is less of a standard and more of a “gravitational core,” drawing applications into a common technology and functionality space rather than riveting them in place by means of a firm engineering standard. Much has already been written about these services, so there is no need to recapitulate that here. The O’Reilly article provides an excellent overview. But what may not be apparent unless you are following this technology closely is that it is evolving, expanding, and diversifying at an astonishing rate, and it is coming—has come—to a campus near you. While it might be difficult to define web services in a sentence or two, we can try to get a handle on it by identifying the technology’s key characteristics. They are diverse. Emily Chang’s eHub site2 provides an excellent overview of Web services. At last count, she documents 1,066 web-based resources using 64 categories, including business, Internet phone and TV, audio and music, collaboration and management, mashups, social web, travel, e-learning, e-mailing (and many more).
