Keeping Up with the Changing Web


Business focus:
IBM, Microsoft, and BEA Systems are joining in a new consortium

called the Web Services Interoperability Organization
--
to try to accelerate the
development of the next
-
generation technology

of the Internet, Web services.
1
The
purpose of this group is to agree on a framework for testing Web software from different
suppliers to verify that it allows the open sharing of data across the Internet. This sharing
will enable Web services, clever sof
tware that can use the Web to find the data it needs in
databases or to share data.

Using Web services, company software handling inventory data could
communicate with the software keeping track of a supplier’s data and, obeying
programmed instructions,
reorder parts automatically when they ran low. An
individual might have an electronic calendar do things like automatically
interacting with software at a dentist’s office to schedule a checkup. . . . The
proponents of Web services say it will lead to big
gains in economic
productivity and convenience.

Individual use:

Feeling web
-
logged, or “blogged”? The use of Weblogs, or “blogs.” is
growing. Weblogs are Internet sites where users can post random thoughts and
commentaries and read musings posted by oth
ers.

Weblogs look like online diaries. One
example of a Weblog is
www.mybluehouse.com/weblog
, where Weblog entries from
France are posted. Pyra Labs runs
www.blogger
.com
, a site that sells Weblog software
subscriptions and services.
UserLand Software also sells Weblog software.


According to John Leo of
U.S. News & World Report,

Andrew Sullivan may be the most
quoted blogger. His 1,000
-
word analysis of President Bush
’s State of the Union message
appeared 33 minutes after the president finished

way ahead of any columns written for
newspapers and magazines. Sometimes he launches attacks on newspaper columnists
around 4 a.m. so blog fans can read his version before they
get to the columns.

One blog supporter has bet that by 2007, more readers will get their news from blogs than
from the
New York Times.

Web enhancement?

In 1990 Tim Berners
-
Lee gave to the world the software innovation
called the World Wide Web. Now he
hopes to enhance it by 2005 with the Semantic
Web, which will allow machines to easily understand and work with the words and
information humans stuff into e
-
mails, documents, and databases.
7

Although computer programs can easily hunt for a header or a key
word in a
document, they don’t understand those words or the context in which the words
appear. The words have meanings to people, not the machines. That greatly
limits the way in which programs can work with information on websites and
stored in documents
.

In the Semantic Web, much of the information could be processed by machines,
its meaning embedded in websites in a way that machines could interpret.
8


As a result of this new development, experts expect that programs could automatically do
many tasks th
at people now handle. Innovations would come about through an evolution
of the Web, not through a replacement of it.


For example, with a few simple commands, someone interested in attending an
out
-
of
-
town business convention could direct his or her comput
er to schedule
the trip, book plane tickets, generate a map from the airport to the convention
center, and reserve a hotel room within a set price range.
