Wirecloud (Application Mashup GE)
Hands-on Webinar (November, 2012)

DIAPOSITIVA 2
A small application or piece of dynamic content that can be easily placed into a web pageOften encapsulate a Web API (directly or through an operator)Can be easily embedded into webpages (HTML snippets)"Mashable" widgets generate/consume events, so that they can be wired together to create a lightweight application mashup This requires a widget platform

DIAPOSITIVA 3
Lightweight application combining data, services and UIs from multiple sourcesDeveloped by either IT or business staff, as well as by end usersCreated in hours or days, not monthsUses a Web Oriented Architecture (WOA)Often relies on internal + external web services (Web APIs)Done at data, logic and/or presentation layers

DIAPOSITIVA 4
Operators represents functionality managed at the presentation layerEmpower the user to create data mashups (Access + Transform data sources) by piping + Web API wrappingEnhance widget functionality by wiring them each other

DIAPOSITIVA 5
Different types of mashups
Presentation-focused (App Mashups) Assemble + wire Example scenario: Highly
personalized information/control dashboards (trouble tickets, stock quote, forge tools, etc.)
Operators represents Piping + Web API wrappingExample scenario: Decouple a “chat” widget from the target service: sms, twitter private msg, email, etc.
Data Mashups: Access + Transform data sources Example scenario: Take data of
insurance polices and merge with feed from National Weather Service
The term mashup encompasses both data and presentation mashups:

DIAPOSITIVA 6
Line of business, “self-service” application developmentDynamic, “at the glass” application assembly, without the underlying components (widgets, operators) needing to know about each other ahead of time (it fosters reusability)Rapid creation of situational / instant applications that solve day-to-day problemsRapid-prototyping of web applicationsUse cases:
Self-service aggregation of information from heterogeneous sources (e.g. sensors)Enabling customer-centric applicationsEffortless syndication of content

Situational ApplicationsRapidly created to address an immediate need of an individual or communityTypically short-lived (a just-in-time solution)Good enoughBuilt by domain experts (knowledge workers) to solve their own problems
Why companies want MashupFoster innovation by unlocking and remixing information in ways not originally planned forQuickly uncover new business insights by easily assembling information from multiple sourcesIncrease agility by supporting dynamic assembly and configuration of applicationsSpeed development and reduce development costs through lightweight integration, reuse and sharing
Targeting the Long Tail: > 90M end-users (incl. Business prof.) trying to solve day-to-day problems
US Estimates for 2012 (double for WW)
< 3M full-time application developers working on software intensive projects (IT department)

Demo Videos
Use case 1: Developing a mashup from the widgets and making it available through a catalogUse case 2: Enhancing / customizing a mashup, starting from the previous oneUse case 3: Developing a event-driven dashboard as an application mashup

Widgets and Mashups are to be offered in the FI-WARE Store GE and managed by the FIWARE Marketplace GE: RDF(S) vocabularies built upon Linked Data principles as Linked USDL extensions

Wirecloud Open Specs: Widget API & App Mashup API
© Javier Soriano
The Application Mashup GE offers two separate APIs that cannot be combined because of their different nature:
FIWARE.OpenSpecification.Apps.WidgetAPI FIWARE.OpenSpecification.Apps.ApplicationMashupAPI
Those APIs are "live" APIs. We are working on offering new functionalities, such as:
Providing widgets with RW access to platform data Getting access to other FI-WARE GEs (i.e. pubsub broker)
