Basic Widget Authoring Process• Make a webapp (HTML5, JS, CSS, jquery etc)• Make a basic config.xml with name, author• Give it an icon (icon.png)• Zip it up• Change extension from .zip to .wgt
Other config.xmlclever stuffI18n/l10n distribute multi-local apps as a single widget!Updates automatic updates! Not patented by Apple!Signing Author-trust and store-trustWidget JS Object Preferences, metadata…WARP Configure access policies for remote services
Mobile Web: Widgets vs Sites• Largely same access to device APIs though widgets may have simpler permissions config depending on the WRT• All files distributed and installed in the package, supporting offline access• Package versioning and updates• Metadata and icons for app store distribution

A Java server application in the Apache Incubator. Includes a W3C Widget parser library. http://incubator.apache.org/wookie* “Wookie” is not a clever acronym. so if you spell it WOOKIE you’re shouting!
Wookie is…• A standalone widget runtime designed for supporting web applications• Enables any web application to become a widget container
• How we went from a funded academic project to an ASF incubator• How commoditization is enabling R&D• Why a very, very small dept with limited funding chose to invest it in this…
the proposition• Implementation of emerging standard• Can be extracted from larger project context as a discrete project• A good fit with ASF - home to other W3C ref implementations• Already some interest from outside the project
Questions I was asked by my boss• “What is our commitment and exposure?”• “How can you work on this when there isn’t a cost code for it?”• “What if we get another project that needs you to work on it?”
The Business Case• With some help from Ross @ OSSWatch…• Identified a “survival budget” for core staff to manage the transition to ASF and maintain basic contributions for 2 years• Identified a range of potential sources of value and funding – New projects – Consultancy – Internal ITS adoption/support
The Proposalhttp://wiki.apache.org/incubator/Wo okieProposalThank you Ross !
The Process• Incubator vote• IP due diligence – Rewriting some code – Lots of emails• CLA• ICLA• Transfer of codebase• Induction
So what happened?• Income generated from this work far, far exceeded the survival budget.• Total income generated for next 4 years: ~£700k from two FP7 projects• Plus very substantial value added by the community• Only actually core funded from Dec 09-Sep10 @ 0.2FTE (around £12k)• Wookie reused by at least six other EU consortia projects• Wookie has already effectively paid for 20% of me and 100% of two developers for the next three years

Added Value• Work contributed to Wookie by the incubator community• Bug fixes• New features• Build and install process• Connection framework• New plugins• New persistence layer• Connectors in PHP, C#, Python, Ruby …• Documentation, screencasts etc
New Partnerships• T-Systems MMS• SAP• Gesfor SA• Huawei• University of Trento• Chemnitz University• University of Madrid• University of Vallodolid• TIE Kinetix• SMART• Promethean• Icodeon• Opera
New R&D• OMELETTE: – Telecom service mashups with widgets – Portable device-agnostic multi-widget workspaces• ITEC: – Interactions between widgets on interactive whiteboards, tablets and mobiles• Apache Rave
New practices• Rather than just build stuff in projects, ask… – Would this be a viable piece of OSS outside this project? – Who is not in our consortium but would contribute? – Are there existing communities we can tap into? – How can we manage this?If its not viable, find out why its not viable and that is a valid research outcome; don’t invest resources building it just because “it’s a deliverable”
So what have we got out of it?• Better software than we could have created alone• More interesting research opportunities• Research impact• Partnerships• Money
