Provided an
accepted mechanism for guarantees of existence exists, search engine
operators could use the guarantee of existence indicated in the
metadata of a piece of information to efficiently search the web for
new information resources.
At present, it
is nearly impossible for search agents to determine how long a
website will be available or when existing content will be changed.
If a website is provided with a guarantee of existence, it will not
be necessary to access it until the guarantee has expired.
Subsequently, a reduction of page requests by search engines, which
burden a system, could be achieved.
Please
note: The guarantee of existence is not supposed to prevent a
document (a concept) from being updated just because availability of
a specific version has been guaranteed.
