Introduction

Evolution: http://blog.zopim.com/2013/11/28/evolution-sale/

• Service Oriented Architectures (SOA)

• SOA itself is an evolving architecture

5th December, 2013

Introduction

• Reference Architectures (RA)

• RAs in context of SOA (SOA-RA)

5th December, 2013

Motivation

• eGovernment Extensive use of Information and Communication Technologies

(ICT)

eParticipation is an important component of eGovernment

• eParticipation Tools Blogs

Discussion Forums

Wikis

Social Media Platforms (Facebook and Twitter)

5th December, 2013

Motivation

• Puzzled By Policy (PbP) eParticipation tool

European Commission Project

Led by INSIGHT @ NUIG, Ireland

Twelve participating countries (9 European)

• PbP Framework Policy Profiler

uDebate

Social Media

5th December, 2013

Motivation

• Inclusion of Social Media Data in PbP Specifically, Facebook, Twitter

Data retrieval, sharing and integration

High volume of heterogeneous data

• Integration with other eParticipation data Data Retrieval…………

High volume………

5th December, 2013

Motivation

• Solution Introduction of SOA

Data integration and sharing made easy through SOA

Effective SOA?

Bring RA into the picture

SOA-RA defined specifically for eParticipation domain

Approach

Reference Architectures (RA)

Batke and Didier, 2007. Batke, B. and Didier, P. (2007). The importance of reference architectures in manufacturing networks. In CIP Networks Conference.

• Definition No universal definition

IBM, SAP, ORACLE, MICROSOFOT etc. have their own way of

defining RA

Our conclusion: a diagram/pattern/specification or a set of

diagram/pattern/specification to:1. Depict the administration of system functions2. Provide a map for how those functions relate to each other.

• Importance[Batke and Didier, 2007]

• Ensure addressing core problem

• Reduces risk of deployment based on known and tested

solutions

• Simplifies decision making

• Relies on proven solutions

• Helps bridging cultural gaps 5th December, 2013

Criterion for RA

Muller, 2008. Muller, G. (2008). A reference architecture primer. Eindhoven Univ. of Techn., Eindhoven, White paper.

• Muller’s Criteria [Muller, 2008]

Should be understandable for all stakeholders

Should be easily accessible

Addresses key issues of domain

Provides consistent models

Should have high quality

Should be up-to-date

Should add value to business

5th December, 2013

Criterion for RA

• Our Criteria Should be applied in conjunction with Muller’s criteria

Considers level of Abstraction

Takes note of context

Most importantly highlights the goal of RA

Service Oriented Architecture (SOA)

Linthicum, 2008. Linthicum, D. (2008). Reader roi. Service Oriented Architecture (SOA) in the Real World.Erl, 2006. Erl, T. (2006). Service-oriented Architecture: Concepts, Technology, and Desing. Pearson Education India.

• Definition Mostly confused because of different definition in different

literatures

A better understanding can be formed after looking at a set of

facts presented by [Linthicum, 2008] and SOA principles

enlisted by [Erl, 2006]

5th December, 2013

Criterion for SOA-RA

• Basic Criterion Make sure to follow general RA Criterion in first place Collect domain specific requirement Communicate requirements properly Involved teams should be made clear about abstraction level,

context and goals Derive a set of principles from requirements that align with SOA

principles Based on principles, define corresponding concepts The defined concepts represent the component that will become

part of reference model The components need to be as much independent and decoupled as

possible Similar components are combined into layers Multiple reference models are combined to create a reference

architecture5th December, 2013

Criterion for SOA-RA

• Most generic and important components Business rules and business process services

Data sharing and transformation services

Infrastructure and component services

Third party communication services

Identity and security services

Integration and event management services

Packaged application services

Presentation Services, registry and repository services

Messaging Quality and Governance

The list of generic components presented here doesn’t imply

direct application, domain specific requirements might introduce

more components not listed here.

Conclusion

• Successful inclusion of Social media in PBP• Big Data Management (Volume, Velocity,

Variation)• Successful implementation of SOA for PBP-Social

Media integration component

• Future Work:• Sentiment analysis of Social Media content

• Integration with other eParticipation tools

• Exploitation of LOD Cloud within eGovernment domain to

further sustain and support eParticipation
