The Semantic Web will bring structure to the meaningful content of Web pages, creating an environment where software agents roaming from
page to page can readily carry out sophisticated tasks for users. Such an agent coming to the clinic's Web page will know not just that the page has
keywords such as "treatment, medicine, physical, therapy" (as might be encoded today) but also that Dr. Hartman works at this clinic on Mondays,
Wednesdays and Fridays and that the script takes a date range in yyyy-mm-dd format and returns appointment times. And it will "know" all this
without needing artificial intelligence on the scale of 2001's Hal or Star Wars's C-3PO. Instead these semantics were encoded into the Web page
when the clinic's office manager (who never took Comp Sci 101) massaged it into shape using off-the-shelf software for writing Semantic Web
pages along with resources listed on the Physical Therapy Association's site.
