A possible solution for the search problem - and for the general issue

of letting automated "agents" roam the web performing useful tasks - is

to provide a mechanism which allows a more precise description of

things on the web. This, in turn, could elevate the status of the web

from machine-readable to something we might call

machine-understandable.

RDF encourages the view of "metadata being data" by using XML (the

eXtensible Markup Language) as its encoding syntax. The resources being

described by RDF are, in general, anything that can be named via a URI

(Uniform Resource Identifier). The broad goal of RDF is to define a

mechanism for describing resources that makes no assumptions about a

particular application domain, nor defines the semantics of any

application domain. The definition of the mechanism should be domain

neutral, yet the mechanism should be suitable for describing

information about any domain.

Once the web has been sufficiently "populated" with rich metadata, what

can we expect? First, searching on the web will become easier as search

engines have more information available, and thus searching can be more

focused. Doors will also be opened for automated software agents to

roam the web, looking for information for us or transacting business on

our behalf. The web of today, the vast unstructured mass of

information, may in the future be transformed into something more

manageable - and thus something far more useful.
