Problem: The farmers have little choice to search forthe best available price and are forced to sell theirproducts in a local market.

Motivation: Grid Computing and Service-OrientedComputing can support required middleware anddevelopment of loosely-coupled, autonomous

services distributed across organizations. Aim: To identify requirements, propose architecture,

design and implementation of various grid services to

computerize nation wide APMCs and privatemarkets to enable seemless trade among buyers andsellers of agro-produce.

Background

The Model Act [1] is formulated to bring reforms in theAgricultural Marketing Process. Additional responsibilitiesare assigned to the existing Agricultural Produce MarketCommittee (APMC) to realize the reforms havingfollowing objectives:

To promote setting up of privately-owned markets To promote direct sale and contract farming

To provide transparency in trading transactions

To provide market-led extension

To ensure payment on the same day

To enable value addition in agricultural produce bypromoting processing

Motivation

A real life example of Agricultural Marketing Process inIndia is considered.

The Model Act is expected to bring reforms in theAgricultural Marketing Process in India.

A typical trade can span across the markets located atvarious places.

Privately owned markets are allowed, food processing andother related industries are allowed to trade directly with

the farmers. Hence the trading in such a competitive market will be

more complex than that in the existing scenario.

Our Proposal

The proposal is mainly depending upon WS-* specifications, specifically Web services Resource Framework WS-RF,

WS-Notification (WSN) specifications,

Grid Services for resource management, job scheduling,and execution and monitoring,

BPEL standard for workflow and composition schemagenerations.

The architecture shown in figure 2 comprises variouscomponents.

All the components are not participating in thisexperiment.

Execution of Seller Grid Service

$ java -DGLOBUS_LOCATION=$GLOBUS_LOCATIONorg.sws.examples.clients.GridManager.Clienthttp://10.100.64.65:8080/wsrf/services/sws/examples/GridManager seller wheat 50 kamla Bhopal 60 direct

Execution of seller grid service will start and will wait for appropriate offer to come froma potential buyer. Seller grid service will receive notification, once an appropriateoffer is floated by a buyer. Initially, following output will be generated:

END POINT STRING:

Here, execution of buyer grid service will start and it will wait forappropriate match to be identified in a market located at Bhopal.

Once market service of a particular location starts executing,

it tries to match potential buyers and sellers. If an appropriatebuyer is found for a seller, appropriate notification is sent toboth of them to inform them about success of entering into atrade deal. Otherwise both of them will wait for a potential

purchaser of a crop. In case of indirect trade mode, the sellerreceives various types of notifications, which are computedfor this trade.

Issues related to execution of workflow in a grid environment

are identified. Attention was towards the utilization and integration of existing

technologies to achieve seamless interoperable integration with

state, transaction, notification and scalability support.

To achieve these objectives, we proposed service-oriented grid

architecture based on relevant specifications and standards in

this area.

We have shown the use of WS-RF to provide statefull webservices, WSN for notification and BPEL to model the business

process with support for transaction and notification.

This work is a part of our ongoing research to achievedynamic event driven Web services composition forautomation of business processes, where diversity isobserved in product, terminology and at process level.

We have demonstrated the use of grid services to providerequired middleware support. Convergence of grid andWeb services standards and specifications for the completeexecution of a business process is discussed in this chapter.

The future work is diverted into several paths: implementation of policy, agreement, negotiation, and use ofsemantic web to provide meaningful integration and coordinationof resources in a grid environment.
