The Future of XML: How Will You Use XML in Years to Come?
Elliotte Rusty Harold, IBM developerWorks

XML's future lies with the Web, and more specifically with Web publishing.
It seems a little funny to have to say that. After all, isn't publishing
what the Web is about? The Web was designed first and foremost as a
mechanism to publish information. What else can it do? Quite a lot. The
last three years have seen an explosion of interest in Web applications
that go far beyond traditional Web sites. Word processors, spreadsheets,
games, diagramming tools, and more are all migrating into the browser.
This trend will only accelerate in the coming year as local storage in
Web browsers makes it increasingly possible to work offline. But XML is
still firmly grounded in Web 1.0 publishing, and that's still very
important... So now you know how you'll write XML in 2008 (Word or
OpenOffice), and you know how you'll send it to the server (APP - Atom
Publishing Protocol). The last question is where to put all this wonderful
XML. Traditionally, this question has had two answers. The first is to
save the XML in a file system. The second is to stuff it in a Binary
Large Object (BLOB) in a relational database. Both are kludges, and
neither performs very well for Web sites. What we need is a database
designed to work with the hierarchical structures of typical Web
documents rather than cutting across them. For the first time, such
databases now exist at multiple scales, they're stable, and they're
ready to use. On the low end, eXist and Berkeley DBXML are looking
better and better. On the high end, expensive big-iron XML databases
like Mark Logic will continue to convert big publishers who can afford
the cost of entry. Hybrid solutions like IBM DB2 9 pureXML will drive
XQuery adoption among customers who need to mix documents with tabular
data. Compared to earlier products like these, the new breed are more
stable, more scalable, and more reliable. Most important, they now
share a standard language, XQuery 1.0, finally released after years
of development.

W3C Releases Extensible Markup Language (XML) 1.0 (Fifth Edition)
Tim Bray, Jean Paoli (et al, eds), W3C Proposed Edited Recommendation

A Fifth Edition of "Extensible Markup Language (XML) 1.0" has been
published by members of the W3C XML Core Working Group. This fifth
edition is not a new version of XML. As a convenience to readers, it
incorporates the changes dictated by the accumulated errata to the
Fourth Edition of XML 1.0, dated 16 August 2006. In particular, erratum
'E09' relaxes the restrictions on element and attribute names, thereby
providing in XML 1.0 the major end user benefit currently achievable
only by using XML 1.1. A preliminary implementation report is available,
together with a Test Suite designed to help assess conformance to
this specification. The XML Core WG wishes to ensure continued
universal interoperability for XML 1.0. To this end, the WG will not
request that this Fifth Edition of XML 1.0 become a Recommendation
until the following criteria are satisfied: (1) At least three months
have passed since the publication of this PER; (2) There are at least
three implementations that pass the test suite for each of the errata
that have been newly applied to the Fifth Edition. Rationale for
Primary Change: "... The proposed change to XML 1.0 will relax the
restrictions on names, used not only for element and attribute names
but also identifiers and enumerated attribute values. Those who prefer
to retain the constraints on names from the previous version of XML
1.0 in their documents will be free to do so, but those who wish to
use names that incorporate these additional characters will be able
to do so."

Oracle Launches Data Integration Suite
Chris Kanaracus, InfoWorld

Oracle has launched the Oracle Data Integration Suite, which combines
traditional data integration capabilities with an array of middleware
and tooling for constructing a service oriented architecture. Data
Integration Suite costs $60,000 per CPU for a package that bundles
Oracle Data Integrator and Oracle/Hyperion Data Relationship Manager
with the company's BPEL Process Manager, enterprise service bus,
application server, business-to-business engine, and business rules
engine. Oracle's suite aligns its data-integration offerings with its
Fusion Middleware line for SOA. Additional options in the suite
include a new pair of data quality tools, Oracle Data Quality for
Data Integrator and Oracle Data Profiling, which the company developed
with Harte-Hanks Trillium Software. Also, Oracle is optionally offering
its Coherence Data Grid, technology acquired through Oracle's purchase
of Tangosol last year, and a number of adapters, including ones for
applications and unstructured content, as options... Marketing materials
announcing the Oracle's release stress the suite's applicability to
heterogenous environments, noting its support for a broad array of
databases, including IBM DB2, MySQL, Microsoft SQL Server, Teradata,
and Oracle.

Microsoft Declares Its Modeling Love With a New Language, 'D'
Mary Jo Foley, ZDNet Blog

A handful of Microsoft's top developers are working to create a new
programming language, code-named 'D,' which will be at the heart of
the Microsoft's push toward more intuitive software modeling. D is a
key component of Microsoft's Oslo software-oriented architecture (SOA)
technology and strategy. Microsoft outlined in vague terms its plans
and goals for Oslo in late fall 2007, hinting that the company had a
new modeling language in the works, but offering no details on what
it was or when the final version would be delivered. D will be a
declarative language aimed at non-developers, and will be based on
eXtensible Application Markup Language (XAML), sources, who asked not
to be named, said. Sources close to Microsoft confirmed the existence
of D, which they described as a forthcoming 'textual modeling language.'
In addition to D, sources said, Microsoft also is readying a
comlementary editing tool, code-namd 'Intellipad,' that will allow
developers to create content for the Oslo repository under development
by Microsoft. Intellipad is the Emacs.Net text editor for which
Microsoft has seeking developers over the past couple of months... At
last week's Lang.Net 2008 conference -- a meeting of programming gurus
from Microsoft and other vendors held on the Redmond campus --
Microsoft's Chief Modeling Officer Don Box provided some more clues
about where Microsoft is going on the tool and platform front with
Oslo. Box said Microsoft wasn't interested in creating some grandiose
1980s' style computer-aided-software-engineering (CASE) tool; it was
thinking more along the lines of providing a class designer. The goal,
according to Box: "putting more and more of your application into data
and putting less in code."

Real Web 2.0: Linking Open Data
Uche Ogbuji, IBM developerWorks

Throughout this column I've placed strong emphasis on the aspects of
Web 2.0 that concern open, shared data rather than flashy effects.
Certainly Ajax is important because when used well it can enhance the
usability of Web sites. But Web feeds, open, Web-friendly APIs, and
third-party plug-in and mashup capabilities are the real substance of
Web 2.0. One community closely associated with the Web's original
stewards, the W3C, is committed to a particular, coherent set of
practices along these lines. The Linking Open Data (LOD) community
combines the vision of the W3C for using semantic features to enhance
the Web with the pragmatism that characterizes mainstream Web 2.0. The
[stated] goal of the W3C SWEO Linking Open Data community project is
'to extend the Web with a data commons by publishing various open
datasets as RDF on the Web and by setting RDF links between data items
from different data sources.' The emphasis on RDF is natural for the
W3C, which has been pushing the technology for a decade, but one
development that gives LOD extra legs is the emergence of influential
voices realizing that insistence on strict RDF format across the board
is probably not the best present strategy for winning over Web
developers. LOD supports RDF as a conceptual model, but the new
emphasis is more on linking and openness than on any one syntax. After
all, RDF is merely URIs, links, and labels, so any model that includes
these three can readily work with RDF systems. The full LOD community
is a penumbra around the W3C-led core who support all the advantages of
opening up data that I've discussed so far in this column, and who see
RDF, Atom, JSON, and so on as merely tools for Web developers to open
up their data. LOD means making it easier for people to discover
important things you place on the Web, and making it easier for them
to do unexpected, fruitful things with them. The next time you have a
Web project, start by thinking of it in terms of what information and
non-information resources are represented in the Web app, and do
everything you can to give each one a well-designed HTTP URI and a
semantically rich data format, and create links, links, and more links.

Grails 1.0 Web Framework Ready
Paul Krill, InfoWorld

The Grails 1.0 open source Web application development framework was
announced this week by G2One, which specializes in Groovy and Grails
technology, and the Grails development team. Grails is built on Java
and the Groovy language. It leverages APIs from the Java enterprise
sphere including Spring, Hibernate, and SiteMesh, G2One and the
development team said. With Grails, Java and Ruby developers get
convention-based rapid development while leveraging existing knowledge
and capitalizing on APIs Java developers have used for years. Plug-ins
enable Grails to work with technologies such as Adobe Flex, Google Web
Toolkit, and the Yahoo UI library. The 1.0 version has been in the
making for two years and eight months. New features including an ORM
DSL (Object Relational Mapping Domain Specific Language) for advanced
mappings, support for easy-to-use filters, and content negotiation.
REST (Representational State Transfer) also is leveraged, as is JNDI
(Java Naming and Directory Interface). ORM DSL allows Grails to support
legacy databases in applications. Filters apply cross-cutting behaviors
to Web applications to apply capabilities such as security, tracing,
and logging. With REST support, Grails allows for existing Web objects
to be converted to XML or JSON (JavaScript Object Notation), with
tasks being automated. With JNDI, Grails provides the ability through
Spring to look up existing programming objects such as a data source.
