6 The Mobile Web – Overview (I) Accessing web applications and contents from mobile handsets – From the old days of WAP to the Mobile Web (HTTP + (X)HTML + CSS + Javascript) Particularities of the mobile environment Delivery Context – A myriad of devices and web browsers (multiple combinations) – Different markup language varieties, image formats, CSS support – Different form factors subject to orientation changes – Different interaction resources (multi-touch, stylus, track ball, numeric keypad, …) – Network latencies, disconnections… Valencia, 12 and 13 April 2010NESSI Projects Summit

7 The Mobile Web – Overview (II) Users use their mobiles to do different tasks – Different Context of Use Mobile Applications and Portals optimized Mobile Web Development is not easy if you wish to support the majority of devices without compromising functionality or the user experience Mobile Web Development is not easy if you wish to support the majority of devices without compromising functionality or the user experience Valencia, 12 and 13 April 2010NESSI Projects Summit

8 The Mobile Web – Why? Valencia, 12 and 13 April 2010NESSI Projects Summit 3 Mb – 57 seg ! 31 Kb – 2 seg 28 Kb – 2 seg 12,5 Kb – 17 seg

9 Voice from the experts Unless websites are redesigned for the special circumstances of mobile use, the mobile Web will remain a mirage. Users won't realize the benefits promised by mobile vendors, and site owners won't reap the profits that would follow from gathering hordes of loyal mobile customers. In user testing, website use on mobile devices got very low scores, especially when users accessed "full" sites that weren't designed for mobile. So, if mobile use is important to your Internet strategy, it's smart to build a dedicated mobile site.

10 MyMobileWeb Valencia, 12 and 13 April 2010NESSI Projects Summit

11 MyMobileWeb - Introduction MyMobileWeb is an open source, standards-based software framework that simplifies the rapid development of mobile web applications and portals. MyMobileWeb encompasses a set of technologies which enable the automatic adaptation of applications to the target Delivery Context (browser, device, network, location,…), thus offering a harmonized user experience. How: – Using an XML-Based language (IDEAL2), that makes it possible the description of device independent user interfaces and their adaptation policies – Using a set of client and server-side runtime libraries that realize the automatic content & application adaptation MyMobileWeb enables the creation of Mobile Web Applications that can adapt seamlessly to multiple devices with minimal effort from the developer Valencia, 12 and 13 April 2010NESSI Projects Summit

12 The Mobile Web – Realizing is potential Making the Mobile Web a reality it is not only a question of using highly capable devices and browsers MyMobileWeb makes it possible what users are expecting from the Mobile Web – Any application / service / portal adapted and optimized for every device used at a given moment – Rich user interfaces enabling higher functionalities while optimizing traffic costs: AJAX, Graphics, Maps – Context-Awareness : providing what I need, now, here … MyMobileWeb provides application and portal developers powerful technologies that enable the creation of advanced, high-quality mobile web applications in time to market without investing a lot of money – Using open and standard technologies – Without the need of highly specialized (and hard to find) developers Valencia, 12 and 13 April 2010NESSI Projects Summit

13 MyMobileWeb - More than 5 years on the edge History – Born on November 2004 as an internal innovation project at TI+D – Released as open source (Morfeo) in November 2005 – From 2006 has been funded by the Spanish Ministry of Industry – In 2007 the project was labeled as Eureka-CELTIC – Now it is a Proyecto Singular y de Carácter Estratégico (Avanza I+D) During the last 5 years MyMobileWeb has made outstanding contributions to the state of the art in the area of the mobile web – MyMobileWeb is a product in continuous development which has been adapting to the permanent changes in the mobile market Valencia, 12 and 13 April 2010NESSI Projects Summit

14 Company: Cod. Name Date MyMobileWeb in 4 steps Valencia, 12 and 13 April 2010NESSI Projects Summit Authoring Deployment User Experience in different Delivery Contexts

15 MyMobileWeb Functional View Valencia, 12 and 13 April 2010NESSI Projects Summit

16 MyMobileWeb – Key Technologies IDEAL2 (Interface Description Authoring Language, version 2), for the declarative description of device-independent user interfaces and adaptation policies. IDEAL2 SCXML, language for describing application flows modeled as state machines. SCXML Device Description Framework concerned with obtaining information about the characteristics of devices and web browsers by interfacing with different Device Description Repositories (DDRs). Adaptation and Rendering Engine, in charge of selecting and generating the final markup, script, style sheets and other resources (images, audio, video) to be delivered to the mobile device. Client-side Framework (a.k.a. Mobile AJAX Framework) which enables rich interactions in different Javascript-enabled browsers. Valencia, 12 and 13 April 2010NESSI Projects Summit

17 Valencia, 12 and 13 April 2010NESSI Projects Summit MyMobileWeb Architectural View

18 MyMobileWeb – Core Functionalities (I) Main Feature: content and application adaptation. Adaptation is a process of selection and generation of the applications user interface or contents in order to: (a) accommodate to the restrictions imposed by the target delivery context (b) to ensure that the resulting user experience is sufficiently harmonized with such a delivery context. Adaptation encompasses a number of sub-functionalities Valencia, 12 and 13 April 2010NESSI Projects Summit

19 MyMobileWeb – Sub-Functionalities Automatic generation of the most suitable markup, style sheets and Javascript to realize the different user interface elements (specified using IDEAL2). – from legacy (WML [16]) to the most modern (WebKit-based) enhanced browsers selection of CSS style-sheets to customize the look-and-feel or layout for different devices. selection of user interface parts (including Javascript code), using W3Cs DISelect 1. pagination of long content such as tables with many rows, menus with many options or forms with many fields. selection or transcoding of different multimedia content (images, audio, video). While selection consists of choosing the best from a set of variants, transcoding implies a transformation process from a source to a target resource. – MyMobileWeb incorporates a simple image transcoding component and can interoperate with any OMA-STI compliant transcoding service, such as the open source Alembik system. internationalization and literal management which consists of selecting literals depending on the delivery context (for example to accommodate a short space by choosing an acronym) or the user preferences (preferred language). Valencia, 12 and 13 April 2010NESSI Projects Summit

20 MyMobileWeb – Core Functionalities (II) Runtime support for a wide variety of user interface components and statistical graphics – input (including automatic completion), date, time, selection, menus, chained menu, table, list, range, placard (for combining text and images), carrousel (for showing sequentially a list of items)... Data and content binding. (declarative) association of user interface components with the data or contents (and possibly their constraints) they are going to display or manipulate. – MyMobileWeb can interoperate with any JSR-170-compliant content repository, such as Alfresco. Awareness of the delivery context, compliant with the DDR Simple API W3C Recommendation. IDEAL2 incorporates an extension which allows to add semantic annotations to user interface descriptions. One possible application of this feature is the automatic completion of forms. Valencia, 12 and 13 April 2010NESSI Projects Summit

21 IDEAL 2 IDEAL2 is the result of four years of research and experience in authoring languages for the description of device-independent user interfaces. Features – Based on W3C standards (namely XForms 1.1, DISelect 1) – Modular and extensible. – To help web authors, the syntax of IDEAL2 is similar to XHTMLs but as an authoring language, it incorporates abstractions and extensionsdescribes user interfaces (UIs) in an abstract manner, i.e. without commitment on how such a UI will be finally rendered. IDEAL2 is only intended to provide the description of a user interface from a structural and behavioural point of view. All the aspects that have to do with look-and-feel and layout are specified by means of CSS2 and extensions. By using IDEAL2 developers can concentrate on the application functionality without worrying about markup languages or scripting capabilities. Valencia, 12 and 13 April 2010NESSI Projects Summit

22 Device Description Framework MyMobileWebs DDR Service provides information about the a priori known, i.e. static, characteristics of a delivery context. – For instance, the display width of a device when it is in its default orientation. MyMobileWeb is able to connect to any DDR supporting the W3Cs DDR Simple API Recommendation. – Connectors with the most popular DDRs such as WURFL, Device Atlas or UAProf are provided off-the-shelf. – Multiple vocabularies of properties, including the W3Cs DDR Core Vocabulary and the WURFLs vocabulary are supported MyMobileWeb implements an AJAX-based mechanism devoted to notify the server when a (dynamic) property changes at client (device) side during a session. – For example the screen orientation Valencia, 12 and 13 April 2010NESSI Projects Summit

24 SCXML State Chart XML (SCXML) is a W3C standard – General purpose language for describing state machines (based on Harel States Tables) – Used to specify MyMobileWebs application flows Application Flows describe the behavior to be performed in reaction to the interaction of the user with the system. – The set of actions to be performed by an application flow does not only depend on the events raised by the user interface but also on the application state. Valencia, 12 and 13 April 2010NESSI Projects Summit

31 MyMobileWebs contribution to standards (I) Mobile Web Best Practices. This W3C Recommendation specifies Best Practices for delivering Web content to mobile devices. The principal objective is to improve the user experience of the Web when accessed from such devices. – MyMobileWeb contributed to this Recommendation with several best practices. – MyMobileWeb is a mobileOK compliant framework Mobile Web Applications Best Practices. This is work in progress. It specifies Best Practices for the development and delivery of Web applications on mobile devices. The recommendations expand upon statements made in the Mobile Web Best Practices (BP1), especially those that relate to the exploitation of device capabilities and awareness of the delivery context. – The MyMobileWeb team has made important contributions to this specification, particularly those related with the optimization of Javascript and DOM operations in order to save bandwidth or battery life. Valencia, 12 and 13 April 2010NESSI Projects Summit

32 MyMobileWebs contribution to standards (II) DDR Simple API. A W3C Recommendation that describes a minimal API for retrieving device properties needed for content & application adaptation. /. / – The MyMobileWeb team leaded the edition of the standard. MyMobileWeb developed and integrated the first open source implementation of the specification. See DDR Core Vocabulary. A W3C Note describing an essential vocabulary of properties for adaptation in the Mobile Web environment. – MyMobileWeb contributed to such a vocabulary with different properties that resulted from our experience on the field. Delivery Context Ontology. The Delivery Context Ontology provides a formal model of the characteristics of the environment in which devices interact with the Web or other services. The Delivery Context includes the characteristics of the Device, the software used to access the service and the Network providing the connection among others. – The MyMobileWeb team participated and contributed in a decisive manner to such an API. Mr José M. Cantera, leader of MyMobileWeb, is the main editor of the document. Valencia, 12 and 13 April 2010NESSI Projects Summit
