Future of the Web

Abstract OWL 2 extends the W3C OWL Web Ontology Language with a small but useful set of features that have been requested by users, for which effective reasoning algorithms are now available, and that OWL tool developers are willing to support. The new features include extra syntactic sugar, additional property and qualified cardinality constructors, extended datatype support, simple metamodeling, and extended annotations. This document is a simple introduction to the new features of the OWL 2 Web Ontology Language, including an explanation of its differences with respect to OWL 1. It also presents the requirements that have motivated the design of the main new features, and their rationale from a theoretical and implementation perspective.

Wall Street has all but given up on Jonathan Schwartz.The chief executive of Sun Microsystems has been pushing one of the most drastic turnround strategies Silicon Valley has seen. Yet he now also has to contend with a severe economic downturn, the early stages of which have already exposed Sun's vulnerabilities: its reliance on expensive high-end equipment that does not sell well when times are hard, and its large exposure to the financial services industry.At barely $3 a share, Sun's $2.3bn stock market value is 40 per cent below its book value, and little more than 1 per cent of its value at the start of the decade. The announcement earlier this month of job cuts of up to 18 per cent of Sun's workforce has done little to change investors' minds.

Open source is the very thing that has crippled Sun, yet Sun is looking to open source, to hobble its competitors and revive its future. We often talk in the technology industry about the need to cannibalize your own business before someone else does it to you. Sun may be a little late off the starting blocks, but it's fascinating to watch its race against time.

Having open-sourced its own Solaris operating system, Sun has now tried to corner the market in open source databases with its $1bn purchase of MySQL, the database management system. It now also has its eyes set on the storage market, with a plan to inflict the same pain on incumbents there that it has itself felt from the rise of Linux. It's a hugely gutsy move. It remains to be seen whether it will work, but with Sun's OpenStorage business growing dramatically faster than the rest of the storage industry, it just might work.

Abstract The Web is designed to support flexible exploration of information by human users and by automated agents. For such exploration to be productive, information published by many different sources and for a variety of purposes must be comprehensible to a wide range of Web client software, and to users of that software. HTTP and other Web technologies can be used to deploy resource representations that are in an important sense self-describing: information about the encodings used for each representation is provided explicitly within the representation. Starting with a URI, there is a standard algorithm that a user agent can apply to retrieve and interpret such representations. Furthermore, representations can be grounded in the Web, by ensuring that specifications required to interpret them are determined unambiguously based on the URI, and that explicit references connect the pertinent specifications to each other. Web-grounding reduces ambiguity as to what has been published in the Web, and by whom. When such self-describing, Web-grounded resources are linked together, the Web as a whole can support reliable, ad hoc discovery of information. This finding describes how document formats, markup conventions, attribute values, and other data formats can be designed to facilitate the deployment of self-describing, Web-grounded Web content.

"Business challenges: (1) Enterprises needed to aggregate/reuse business content trapped in disparate repositories: Different systems deployed in different departments, Systems inherited through business acquisition and merger. (2) Companies needed to get up-to-date information from business partner's repository: E.g. Aircraft maintenance crew needed to access manufacturers' vast manual repository to get the latest spec and procedure to comply with FAA regulation. (3) ISVs wanted a single application code-base that can be deployed in different repository environments: Lower development and maintenance cost, Bigger addressable market... Content Management Interoperability Services is a Web-based, protocol-layer interface to enable application to interoperate with disparate content management systems. It is platform-and language-agnostic, message-based, with loose coupling.

The specification was drafted by EMC, IBM, and Microsoft in a project started October 2006. Additional collaborators include: Alfresco, Open Text, Oracle, and SAP. Interoperability has been validated by all seven vendors.

John McCreesh, an evangelist for OpenOffice.org, the main open-source competitor to the Microsoft Office productivity suite, told ZDNet UK on Wednesday that he was surprised to hear Microsoft was continuing to work on OOXML's compatibility. "The feeling had been that OOXML was dead in the water, so it's interesting to see that Microsoft is still trying to revive it in the marketplace," said McCreesh. "The response in the marketplace [to OOXML] hasn't been that encouraging, but they've clearly decided it's worth another push."

Extensible Markup Language (XML) embodies the potential to alleviate many of the interoperability problems associated with the sharing of documents and data. Realizing the potential requires cooperation not only within but also across organizations. Our purpose is to facilitate the efficient and effective use of XML through cooperative efforts among government agencies, including partnerships with commercial and industrial organizations.

I am thrilled to announce today the release of a new version of the W3C Markup Validation Service, also known as "HTML Validator". Use it online http://validator.w3.org/ .... or download it: it is Free and Open Source http://validator.w3.org/source/ The new version, 0.8.4 may sound like a very minor step from the version 0.8.3 released in August, but this new release of the W3C Markup Validator brings some very important change: in addition to checking documents against etablished standards such as HTML 4.01 and XHTML 1.0, the validator can now check documents for conformance to HTML5, thanks to the integration with the Validator.nu html5 engine.

HTML5 is still work in progress and support for this next generation of the publishing language of the World Wide Web will remain experimental. The integration of the html5 engine in the validator should provide experimentation grounds for those interested in trying on authoring in this new version of HTML, as well as a feedback channel for the group working on building a stable, open standard.

Microsoft's newest facility is drawing lots of oohs and ahs from experts in this specialized field. Most data centers are open, warehouse-style buildings filled with racks of gear. But the first floor of this vast 700,000-square-foot facility looks more like an indoor parking lot, with gear packed into preconfigured shipping containers. Suppliers such as Sun Microsystems (JAVA) and Rackable Systems (RACK) have been advocating similar approaches for years, but this is by far the most ambitious implementation. Each of the containers can hold 2,500 servers, and the floor can hold up to 224 containers. That's a potential maximum of 560,000 servers. "They're pushing the concept to the extreme," Cappuccio says.

To be sure, we should not - must not - try to reframe the traditional definition of a document. For those mainstream folks that will make up the bulk of the user population for the foreseeable future, their definition of what a document is is set, and it would be folly to try and change this. But neither should we let that definition carry forward, tainting more capable formats with the legacy of its limited capabilities. No, we need a new definition or term, I believe. Something more accurately descriptive, and yet non-threatening. Database? Too intimidating, too misleading. Web page? Likewise. Container? I don’t love it.

A survey by Gartner found that the number of enterprises planning SOA adoption this year dropped by more than half, to 25 percent from 53 percent in 2007. The number of companies with no plans to adopt SOA jumped to 16 percent from 7 percent.

“ARM believes this partnership will develop optimized Adobe Flash and AIR implementations that will run on billions of devices from our partners such as pocket-sized mobile devices, mobile computing platforms, set-top boxes, digital TVs and automotive infotainment,” said Ian Drew, vice president, Marketing, at ARM

Today, in an effort to bring more of the Web to mobile devices, Adobe and microchip maker ARM, which powers 90 percent of mobile phones worldwide, have announced a collaboration to ensure that Adobe's software runs well on future ARM devices. Specifically, the companies say that Adobe's Flash Player 10 and AIR (a platform for building complex Web applications) will be compatible and optimized for the ARM chips available in 2009. While ARM is used in a huge number of mobile phones, the announcement has broader implications: the chips are also used in set-top boxes, mobile Internet devices, personal media players, and automotive platforms.

In 2006, the European Commission has started the revision of the European Interoperability Framework (EIF) and the Architecture Guidelines (AG).

The European Commission has started drafting the EIF v2.0 in close cooperation with the concerned Commission services and with the Members States as well as with the Candidate Countries and EEA Countries as observers.

A draft document from which the final EIF V2.0 will be elaborated was available for external comments till the 22nd September. The proposal for the new EIF v2.0 that has been subject to consultation, is available: [3508 Kb]
