28 Ottobre 2014 — Il World Wide Web Consortium (W3C) ha pubblicato una Recommendation di HTML5, la quinta versione del formato utilizzato per realizzare pagine e applicazioni Web, e base per l'Open Web Platform. Per gli sviluppatori di applicazioni e per il mercato HTML5 significa un insieme di funzionalità su cui ci si potrà basare per i prossimi anni. HTML5 è ora supportato su una larga varietà di dispositivi, riducendo il costo di creazione di applicazioni evolute che possono essere utilizzate dagli utenti ovunque.
"Oggi noi consideriamo naturale avere video e audio nativi nei browser, e utilizzare un browser in un telefono," ha dichiarato Tim Berners-Lee, Direttore W3C. "Ci aspettiamo di poter condividere foto, fare acquisti, leggere le news, e cercare informazioni ovunque, su ogni dispositivo. Anche se rimangono invisibili a molti utenti, HTML5 e l'Open Web Platform stanno indirizzando queste esigenze emergenti degli utenti."
HTML5 introduce il supporto nel Web di video e audio senza necessità di plugin; l'accesso programmatico a schermi che dipendono dalla dimensione del dispositivo, il che è utile per la visualizzazione di immagini, per la grafica dei giochi, o per altre applicazioni grafiche; il supporto nativo di grafica vettoriale (SVG) e di formule matematiche (MathML); notazioni importanti per la scrittura dei paesi dell'Asia dell'Est (Ruby); funzionalità che permettono di rendere accessibili le applicazioni evolute; e molto altro ancora.
HTML5 è utilizzato da anni. Secondo il 2014 Vision Mobile Survey, il 42% di 10.000 sviluppatori intervistati sta utilizzando la combinazione di HTML, CSS, e JavaScript per tutto o parte delle loro applicazioni mobili. Gartner ha identificato HTML5 come una delle loro 10 tecnologie e soluzioni mobili più importanti per il 2015 e il 2016, sostenendo che HTML5 "sarà una tecnologia essenziale per chi realizza applicazioni su piattaforme mobili."
Per consentire di realizzare la promessa di "scrivere una volta, distribuire ovunque" di HTML5 e dell'Open Web platform, durante i 22 mesi da quando W3C ha annunciato il completamento della definizione di HTML5, la comunità W3C ha continuato ad arricchire l'HTML5 test suite, che include oltre 100.000 test e continua a crescere. L'iniziativa Test the Web Forward gioca ora un ruolo importante e crescente per la realizzazione dell'interoperabilità dell'Open Web Platform.
Oggi, con la pubblicazione della Recommendation, chi implementa software può beneficiare di un impegno di licenze Royalty-Free da parte di oltre sessanta aziende secondo la Patent Policy del W3C. Consentendo agli implementatori di utilizzare la tecnologia Web senza pagare royalties è fondamentale per rendere il Web una piattaforma dove fare innovazione.
Anche se HTML5 è ampiamente utilizzato e popolare tra gli sviluppatori, abbiamo ancora molto da fare per raggiungere una delle promesse della Open Web Platform: abbassare il costo di sviluppo delle applicazioni multipiattaforma potenti. In un post sul blog di ottobre, il CEO W3C Jeff Jaffe afferma che "ora che HTML5 è fatto, il W3C dovrebbe fare di più per rafforzare le parti della Open Web Platform di cui gli sviluppatori hanno bisogno più urgentemente per il successo. "Per aiutare a comunicare e guidare l'accordo su tali priorità, Jaffe enumera "Le fondamenta per l'applicazione" da rafforzate per realizzare la piattaforma della prossima generazione:
W3C discuterà questo nuovo quadro ed il suo impatto sull'agenda W3C nel corso del meeting annuale dei Membri (TPAC) che ci sarà questa settimana.
Fondamenta più forti renderanno anche più facile incorporare le nuove funzionalità per il Web che vengono proposte ogni giorno, dentro e fuori il W3C. W3C sta ampliando il suo lavoro per comprendere casi d'uso delle aziende che operano nell'ambito dei pagamenti online, nell'industria automobilistica, nell'editoria digitale, nelle telecomunicazioni e nell'intrattenimento digitale. Allo stesso tempo, 4500 ingegneri stanno scambiando e confrontando nuove idee per il Web in più di 180 Community and Business Groups.
W3C desidera ringraziare per primo Ian Hickson (Google), il principale architetto della specifica HTML5, che ha fornito contributi fondamentali al linguaggio HTML.
W3C ringrazia i co-Chair del Working Group HTML Paul Cotton (Microsoft), Sam Ruby (IBM), e Maciej Stachowiak (Apple) per la loro guida nel portare HTML5 a diventare una Recommendation, e l'intero Working Group HTML per il suo contributo.
W3C ringrazia anche:
Il World Wide Web Consortium (W3C) è un consorzio internazionale nel quale le organizzazioni membri, uno staff full-time e il pubblico, lavorano insieme al fine di sviluppare gli standard del Web. Il W3C porta avanti la sua missione principalmente attraverso la creazione degli standard del Web e di linee guida concepite per assicurare una crescita del Web a lungo termine. La Open Web Platform è uno degli obiettivi principali del momento. Più di 375 organizzazioni sonoMembri del Consorzio. Il W3C è gestito congiuntamente dal MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) negli Stati Uniti, dall' European Research Consortium for Informatics and Mathematics (ERCIM) con sede amministrativa in Francia, dalla Keio University in Giappone, e dalla Beihang University in Cina, e ha Uffici in tutto il mondo.

Intel strongly supports the power of cross-platform development enabled by HTML5 for both application and website development. We know developers are constantly pushing to maximize revenue by publishing apps that work across multiple screen sizes and operating systems, and HTML5 tools allow them do that while reducing development costs and time to market. Intel recognized this need early, and we are investing in standards development at W3C and software such as the Crosswalk project and Intel XDK that help developers take full advantage of HTML5.

It’s good to see HTML5 reach the Recommendation stage. We were one of the first organizations involved in HTML5 because we believe in continuing to evolve the open Web platform to support innovation and help users. We contributed many widely adopted technologies such as WebGL and helped pioneer technologies like WebRTC. We have also expanded the functionality of the Web on mobile through the use of WebAPIs, bringing Web app developers the power to access phone hardware. Many of these APIs are currently going through the standardization process. We’re now working with the W3C to help lead the work behind the HTML5 test suite, ensuring that tests can be run in an automated way, so that users and developers can benefit from more consistent behavior between browsers.

HTML5 is a great leap forward for an accessible web. In HTML5, accessibility is a core design principle. For the first time the semantics of HTML have been mapped, and implementation requirements defined in terms of the way HTML semantics are conveyed to people using assistive technologies. The addition of new interactive controls, native video and captioning, and new structural elements in HTML5, make it easier than ever for developers to create HTML interfaces that are usable by everyone. The inclusion of WAI-ARIA in HTML also provides developers with the tools and information to create accessible custom content and controls that extend the core features of HTML. The Paciello Group (TPG) is both proud and honoured to have contributed to the development of HTML5, but recognises that it is not an end in itself. HTML5 represents a very positive step in the evolution of the language of the web, and TPG welcomes the opportunity to continue contributing to its positive development.
Mike Paciello, Founder The Paciello Group (TPG)
HTML5 represents to us a stable cross-platform technology for interactive applications which we support in our applications. Profium would like to thank those in and outside of W3C who have contributed to the development effort.
