Challenges of Information Collaboration

Does Web 2.0 leapfrog Internet constraints?

Roles Methods Responsibilities Context Scalability / Level of Service

slide 3

Example interface: Amazon.com AWS

3) Delivered entirelyvia XML / REST andAmazon AWS

2) HTML “look” rendered dynamically via XSLT

QUESTIONS?

•Who controls content? •What role is information playing? •Who controls access/ service?•Who manages changes?

ROLES?•Virtual Merchant•Competitor•Comparison service

•Shopper•Search agent•Alerter

1) XML delivers: Catalogue Prices Stock / Supplier

slide 4

Example Web 2.0 application Mash-up Amazon AWS with Mapping Service Show who has particular products

geographically Challenges – finding consistent geographic

information in AWS catalogue data Encouraging AWS suppliers to provide more

geographic markers Amazon could “game” your application by

manipulating the sequence information is provided in – for preferred merchants

Delivery Methods Synchronous (near real time) –

REST/SOAP/ebXML Asynchronous (interaction model) – ebXML/

Responsibilities

MoU / MoA setup / enforcement Role clarification and determination Short term and long term

commitments / implications Sustainable business model Technology stewardship / control Notification of changes Enabling agent technologies Fair play and neutral information

slide 7

Context

Enabling context is challenge for next generation information collaboration

Core components approach founded on need to understand and use context

Context in legacy systems is hidden inside static code and not exposed

Ability to use open public standards to expose rules and context in consistent way – OASIS CAM work

slide 8

Summary Early adopter applications are finessing

most of these questions with very limited use models, and constrained roles

Human interpretation of information presentation avoids difficulties with machine handling of diverse sources (BPM “above the line” human workflow)

Business Process Integration will be increasingly the challenge (BPM “below the line” human workflow control / machine tasking – enterprise application integration)
