Mashup?!?!

Its a Hybrid Web Application

Reuse formatted data from existing sources

Access and display data with dynamic JavaScript AJAX, DHTML

Analogous to Portal Servers Portlets writtenin J2EEor.NET

Mashups written with mostlyJavaScript

Mashupwidgets workinboth .NET and J2EEenvironments

More of a design philosophy than a tool or a framework

WhatstheMashup DesignPhilosophy?

1) Separate yourinformation from its presentation

2) Upgrade your enterprise architecture for easy data access1) Service-Oriented Architectures (SOA) withSOAP

2) Resource-Oriented Architectures (ROA) withReST

3) Create an easy-to-use JavaScript API for data access1) AccessSOAPorReST services with AJAX

2) LoadRSSorotherXML-formatteddata

3) Keepitsimple! Dont breakthe web!

4) Tell people about your API

5) Step back, and see what happens!

Whatsthe ValuetoMe?

If data is easy to reuse; innovation is bound to follow Noenterprise Javalearningcurve!

JavaScriptWidgets, insteadofcomplex J2EEPortals

Don't need enterprise programmers for enterprise products! Mashupsruninusers browser, notanappserver

Security, performance, uptime managedinyourinfrastructure

TechnologyBehindMashups

Back-End: data repositories Largeenterpriseapplications:ERP, CRM, ECM

Raw databasetables

Middle Tier: application server Securelyconnectto backenddatarepositories

Single-sign-on strongly encouraged

SOA / ROA interface

Publishcontentstaticallyin JSON orXMLformat

Placedynamiccontentinacache foroptimalperformance

Front End: web browser widgets (JavaScript,Flash, Silverlight) Usecustom APIconnectortoMiddle Tier

EnterpriseMashupChecklist

Google Maps is the gold standard Publiclyavailablestaticresources:images, JavaScript

Easytouse JavaScript API

Also supports XML, KML, and JSON

LimitationsofEnterpriseMashups

Accessibility for the blind Text-to-speechreadersdontsupport JavaScript

Have not been seriously updated since 1998

Existing web standardsthat ban JavaScriptareobtuseandoutdated

WAI, WCAG 1.0, WCAG 2.0, Section 508

Accessibility solutions Avoidstandards, usenew tools, empowerthehandicapped!

Web 2.0 can be much more empowering than Web 1.0

Use Firevox andAxsJAX toaddaccessibilityto AJAX andMashups

http://www.firevox.clcworld.net/

http://google-axsjax.googlecode.com/

Use mashups to add accessibility to non-accessible pages!

The FutureofMashups

App servers used more to mashup-enable back end systems

Service-Oriented Architectures more common Lendthemselvesvery wellto mashups

As do Resource-Oriented Architectures MakeEnterpriseServiceBus (ESB)optional

Keep the bar low for hobbyists

New formats:

JSON willsurpass XMLfordatatransfer ATOM willsurpassRSSforsyndication

Accessibility standards will eventually catch up Goodtoolsandeaseofuseare moreimportantthan standards

Mashups empower users to find data in silos

Enterprise Widgets replace portal servers AJAX and JavaScriptreplaces J2EEand .NET forsomeportals
