enables users to remotely control the device and
monitor its operating state. The consumer receives a
full set of tools for would-be resale of the item,
which also contributes to the product’s added
consumer value.
There can be different approaches to site editing.
Editing can be arranged:
• On the side of the server hosting the
website
• On the side of the client
• With the help of specialized Web-
services
In the first case the customer sends modification
requests in response to which the host server
modifies the information. In the second case the
client modifies the modules him/herself. In the third
case the site is maintained by specialized Web
services on behalf of and for the client, and the host
server’s role is limited to storing the information.
Each of the above arrangements has its strengths
and limitations.
The advantages of accomplishing the site
maintenance tasks directly on the host server include
low dependence on the qualities and capabilities of
the web client (user’s browser) and moderate load
on data links (the sever only receives requests to
modify the information, whereas modification
proper is performed on the server). However, this
approach presupposes availability of a high capacity
server with necessary software components (at least,
an XML parser, an XSLT processor and
environment for program execution). These
requirements can make the hosting services
prohibitively costly.
The strengths of managing the site on the client
side include much lower demand for the server
capacity and, hence, a lower cost of site hosting. But
this places stringent requirements upon the client
(the same as the server requirements in the fist
instance). Furthermore, in this case the network load
is much higher due to exchange of complete
information modules between the client and the host
server (though this demerit can be minimized by
optimized distribution of information between
modules).
The third approach involves transfer of all site
editing functions to an independent set of Web
services. This will reduce requirements to both the
server and client, though the cost of developing
specialized Web services may pose a great hindrance
to introduction of the entire system.
4 WEBID: MOTIVE FORCE FOR
GLOBAL TRADE
Support of globalization processes is another
challenge coming into being with adoption of the
system . The buyer and the needed product can be
located in different countries, with dissimilar trade
and export/import regulations. Moreover, a
transaction perfectly lawful in one country can turn
out illegal in another. In such cases transfer of the
website ownership rights should be prevented. We
wish to propose a mechanism that will effectively
address this issue.
If the product is sold locally and does not cross
national borders, transfer of the privileged access
right to the new owner is performed by a local
access control server. In case of an international
transaction (when the commodities cross state
borders), transfer of the privileged access implies
involvement of both local and national access
control servers of the buyer’s and seller’s countries.
National servers check if the product may cross the
border and control the appropriate change of local
access servers associated with the product website.
Let us consider a case illustrating conveyance of
the privileged access right associated with an
international sale.
A company, registering a sale, sends a
transaction confirmation to the appropriate local
access control server, situated in the seller’s country
and currently involved with the product website. The
local server checks whether the transaction is
international. If the check is positive the server
reports the transaction to the national control server
of the seller’s country. The national server examines
the legitimacy of the product export. If it is legal the
national server of the seller’s country informs the
national access control server of the buyer’s country
about the transaction. The latter examines the
legitimacy of the product import. Thus, if the
product transfer is legal in both countries, a change
of the local access control server takes place. As a
result, the product becomes associated with the local
access control server in the buyer’s country. Finally,
the new local access control server grants the new
owner the right of privileged access to the website.
If the product import is illegal, conveyance of
rights will not take place and the illegitimate
transaction will be reported to the relevant
authorities.
We witness an onset of a new world of goods
turnover, of truly free global trade. Supply links turn
into supply nets. Reuse of products will open the
world of technology-intensive goods to those who
cannot afford buying high tech products at the
manufacturer’s price, it will alleviate the stress load
