A Semantic Web Primer for Object-Oriented Software Developers
Holger Knublauch, Daniel Oberle, et al (eds), W3C SWBPD Note
Members of W3C's Software Engineering Task Force, part of the Semantic
Web Best Practices and Deployment Working Group (SWBPD, have released
a document explaining how object-oriented applications can be designed
and implemented with the help of Semantic Web technologies. According
to the abstract for the "Semantic Web Primer for Object-Oriented Software
Developers," Domain models play a central role throughout the software
development cycle, from requirements analysis to design, through
implementation and beyond. As such, great progress has been made in the
consistent use of models throughout this process. Modern software
development tools with support for the UML and code generation as well
as Model-Driven Architectures allow for developers to synchronize and
verify technical implementation with user requirements using models.
However, the reusability of domain models is often limited because they
are, by definition, domain specific and only take into consideration
abstractions needed to make possible a solution within the confines of
their own individual problem space. But the Web is broader than that and
provides a multidimensional solution space capable of referencing an
almost limitless set of domains. While much of our software becomes
increasingly embedded in the Web, our development processes do not
fully exploit the potential of model reuse from the Web yet. The note
therefore introduces Semantic Web languages such as RDF Schema and OWL,
and shows how they can be used in tandem with mainstream object-oriented
languages.

SOA Software Rolls Out Registry-Independent SOA Suite
Darryl K. Taft, eWEEK
SOA Software has announced that its service-oriented architecture and
Web services management, security and run-time governance suite is
registry-independent and supports registry offering from Flashline,
Infravio, LogicLibrary and Systinet, a division of Mercury Interactive.
The announcement validates the company's registry-independent approach
and signals the next phase in enterprise SOA adoption, in that the SOA
market is maturing with UDDI (Universal Description, Discovery and
Integration) registries as core building blocks of SOAs, said officials
at Santa Monica, Calif.-based SOA Software. Anne Thomas Manes, vice
president and research director at Burton Group, in a statement said,
"Registries can use SOA management solutions to help manage the
service provisioning process, and SOA management solutions can use
registries to maintain information about managed services and to learn
about new services that need to be provisioned and managed." Flashline's
registry software interoperates with SOA Software's products through
UDDI Version 3, according to Cathy Lippert, vice president of
product management at Flashline.
DIA: Interoperability Runs Through Service-Oriented Architecture
Dawn S. Onley, Government Computer News
The intelligence community is moving beyond collaborative applications
to achieve interoperability across its agencies and toward building a
service-oriented architecture. The Defense Intelligence Agency feels
that true interoperability must occur at the data level, instead of the
system level. To this end, the agency is building a SOA with a set of
common data standards that will use Web services, XML, meta-data tagging
and other tools that should ease collaboration.
Vasont CMS Provides Standard DITA Setup
Staff, eCONTENT Magazine
Vasont Systems, a provider of content management software and data
services, has announced that a standard Darwin Information Typing
Architecture (DITA) setup is included with every installation of the
Vasont Content Management System. Vasont's standard DITA setup is
included at no extra cost and users can choose to install the optional
DITA setup when installing Vasont. In addition, Vasont is able to
support any XML DTDs such as DocBook and S1000D. For users with complex
content, Vasont also supports proprietary DTDs created to accommodate
an organization's specific business logic.

IBM Goes After the Midmarket with SOA Offerings
Ed Scannell, InternetWeek
IBM on Monday kicked off a redoubled effort to drive its services-
oriented architecture (SOA) initiative down into the midmarket,
announcing at its PartnerWorld conference a raft of programs, tools and
software directed at business partners. Chief among the new offerings
is an SOA Specialty within its PartnerWorld Industry Networks that will
provide technical enablement and a skills-building road map for partners.
The program makes available a number of benefits for those partners who
reach milestones, including access to SOA Connection Events, which
allows them to meet with SOA sales specialists, get discounted print
advertising and help with closing SOA-related deals. Partners who
become members of SOA Specialty will be included in the company's SOA
Business Central, which is a federated catalog listing IBM and SOA
software created by all of its business partners. The catalog is
expected to contain more than 3,000 SOA industry-specific assets or
services, combinations of software code and best practices. SOA Business
Central will include the upcoming WebSphere Registry and Repository,
which details how partners can read and publish services and change
management on those services. Trying to build momentum for its upcoming
DB2 Viper database, expected this summer, the company also announced
the DB2 Viper early partner community. The company will supply partners
who join the community with education and product-launch participation.
IBM thinks Viper is critical to SOA because of the XML portion of the
database.
Migrating to WSE 3.0
Aaron Skonnard, Microsoft MSDN Magazine
The new version of Web Services Enhancements (WSE) for the Microsoft
.NET Framework simplifies the process of building secure Web services.
What you may not know is that most of these improvements derive from
some core architectural changes made in WSE 3.0. This column discusses
what's changed and examines the major migration issues you'll face in
moving to WSE 3.0. The new version offers simplified security through
a new-and-improved policy architecture, and support for sending large
amounts of data with Message Transmission Optimization Mechanism (MTOM).
Additional changes include improved session management (via
WS-SecureConversation), support for hosting ASMX services outside of
IIS, and support for the latest WS-* specifications. Although the WSE
team tried hard to ensure backward compatibility, some of these changes
affect the core programming model that you must address to update
existing WSE 2.0 solutions. WSE 3.0 supports the latest WS-*
specifications -- the same ones supported by Windows Communication
Foundation (WCF) -- making WSE 3.0 and WCF wire-compatible. This means
WCF clients can interoperate with WSE 3.0 services and vice versa,
removing the need for continued migration.
Accessing Enterprise Information Systems in a Service-Oriented Architecture
Ahmed Abbas, IBM developerWorks
Enterprise Information Systems (EIS) are key IT assets in any
organization. Service-Oriented Architecture (SOA) makes EIS available to
other members of its enterprise service bus. This article discusses the
underlying technologies for accessing EIS in a Service-Oriented
Architecture, along with tooling and target runtime to implement such an
access. This article provides an overview of the technologies used in a
J2EE environment to access EIS, and how these technologies can be
extended to fit in a Service-Oriented Architecture. The author starts
with a walkthrough of the technologies, and then discusses the tooling
and runtime that enable implementations based on those technologies. A
listing of possible tasks for implementing such an access to EIS using
these technologies, tooling and runtime is included.
Writely = Microsoft's Pearl Harbor?
Dan Farber and Gary Edwards, ZDNet Blog
Writely is a masterpiece of an ODF AJAX engine, able to upload any
OpenDocument file for collaborative work, publication, and/or
distribution. Highly structured information in, highly structured
collaborative information out. All of which is Internet ready. The
killer for Microsoft is that they now face an open stack of highly
structured, Internet ready information services that with the flick of
the download switch could easily stretch across the over 450 million
desktops that make up the mighty Windows monopoly base, over every
Linux, OSX, and Solaris desktop, up through Writely collaboration
services, through the Google mash of services and information and out
across the Open Internet, and back again. Amazing what can happen when
you finally are able to separate information from application, package
it in a highly structured self describing open XML file format, and
put the power of Google behind it.
