WSO2 has announced the launch of the WSO2 Web Services Framework for
PHP (WSF/PHP) 1.0 open source framework for providing and consuming Web
services in PHP. WSF/PHP 1.0 is "the only extension to the popular PHP
scripting language that supports the full Web services (WS*-) stack.
For the first time, developers can bring to PHP the security and
reliable messaging that are required for trusted, enterprise-class
SOAP-based Web services." WSF/PHP 1.0 is one of the first PHP
extensions to support the Web Services Description Language (WSDL)
on both the client and server side, as well as backward compatibility
with the PHP5 SOAP extension. As a result, developers can create new
PHP-based Web services and enable the use of existing code in Web
services that take advantage of the WSF/PHP's enterprise-class
capabilities. WSF/PHP 1.0 is a binding of the Web Services Framework
for C (WSF/C) into PHP, providing a fully open source PHP extension
based on Apache Axis2/C, Apache Sandesha2/C, and Apache Rampart/C.
The WSO2 Web Services Framework for PHP supports basic Web services
standards, including SOAP 1.1, SOAP 1.2, WSDL 1.1 and WSDL 2.0. It
is fully tested and provides proven interoperability with Microsoft .NET,
the Apache Axis2/Java-based WSO2 Web Services Application Server (WSAS),
and other J2EE implementations. Key features of WSF/PHP 1.0 are: (1)
Full support for the WS()- stack includes WS-Addressing, WS-Security,
WS-SecurityPolicy, WS-Reliable Messaging, and SOAP Message Transmission
Optimization Mechanism (MTOM). (2) Secure Web services are enabled by
advanced WS-Security features, such as encryption and signing of SOAP
messages. Users also can send messages with UsernameToken and TimeStamp
support. (3) Reliable messaging for Web services and clients means
basic SOAP messages, as well as messages with attachments can be sent
in a reliable way. (4) Backward compatibility with PHP5 lets developers
use their existing code as is within WSF/PHP. (5) WSDL generation lets
developers generate WSDL for PHP service scripts (serving WSDL 1.1 or
WSDL 2.0). (6) WSDL mode supports a contract-first style of
implementing Web services. A user can simply provide a WSDL and
implement Web services and clients based on the interface given in the
WSDL. (7) Attachments with Web services and clients take two forms.
Users can send and receive attachments with SOAP messages in optimized
formats and non-optimized formats with MTOM support. (8) REST support
lets a single service be exposed both as a SOAP-style and as a
REST-style service. The client API also supports invoking REST services
using HTTP GET and POST methods. As a fully open source solution
released under the Apache License 2.0, WSF/PHP 1.0 does not carry any
software licensing fees.

XML to DDL Imports, Synchronizes Database Schemata
The Freshmeat project known as xml2ddl provides a set of Python
programs under the GNU General Public License (GPL). Given a working
Python runtime environment, this set of tools works on many operating
systems, including most Windows, Linux, and UNIX platforms. It also
works with the following database engines: PostgreSQL, MySQL, Oracle,
and Firebird. Basically, xml2ddl permits users to convert an XML
representation of a database into a corresponding set of SQL or DDL
statements. According to its creator and custodian, Scott Kirkwood,
"XML to DDL strives to be database independent so that the same XML
can be used for a variety of databases. This is great for quickly
testing out a variety of databases for performance, for example".
Project description: XML to DDL is a set of Python programs that
converts an XML representation of a database into a set of SQL or DDL
(Data Definition Language) commands. In addition, it can examine the
difference between two XML files and output a sequence of SQL statements
(normally ALTER statements) to bring one database up-to-date with the
XML schema. You can also download the XML schema directly from the
database. Finally, there's a tool to convert your schema into HTML for
documentation purposes. XML to DDL currently supports the most recent
versions of PostgreSQL, MySQL, Oracle, and Firebird databases."

Mozilla Aims at Cross-Site Scripting With FF3
Web 2.0 has enabled a broad array of Websites to be more engaging for
users. It has also enabled a new and now very common attack, namely
cross site scripting, commonly referred to as XSS attacks. Mozilla is
aiming to put an end to XSS attacks in its upcoming Firefox 3 browser.
The Alpha 7 development release includes support for a new W3C working
draft specification that is intended is secure XML over HTTP requests
(often referred to as XHR) which are often the culprit when it comes
to XSS attacks. XHR is the backbone of Web 2.0 enabling a more dynamic
web experience with remote data. The W3C working draft is officially
titled, "Enabling Read Access for Web Resources." It is intended to
define a mechanism by which Web developers can safely provide
cross-site Web resource access. The specification will let developers
define via an HTTP header or an XML instruction which sites are allowed
read-access and which are not. A typical XSS attack vector is one in
which a malicious Web site reads the credentials from another that a
user has visited. The new specification could well serve to limit that
type of attack though it is still incumbent upon Web developers to be
careful with their trusted data. The W3C working draft warns that
"user agents which implement this specification should take care not
to expose other trusted data (cookies, HTTP header data) inappropriately."
In addition to the new XSS support in Firefox 3 Alpha 7, Mozilla
developers have also fixed some bugs and implementation errors that
cropped up in the Alpha 6 release, which came out in early July. The
latest release isn't just about bug fixes and new feature support.
Mozilla developers have actually dropped support for the SOAP Web
services messaging protocol, according to the official Alpha 7 release
notes. Firefox 3 is Mozilla's next generation browser and will be the
successor to the current 2.x browser. The open source group has been
working on Firefox 3 (code name Gran Paradiso) since October of 2006
when the first Firefox 3 alpha appeared.

Public Review for OASIS Production Planning and Scheduling Specification
Members of the OASIS Production Planning and Scheduling (PPS) Technical
Committee have approved a Public Review Draft of the PPS (Production
Planning and Scheduling) specification. The review extends through
21-October-2007. The PPS Standard deals with problems in all
manufacturing companies who want to have a sophisticated information
system for production planning and scheduling. The PPS standard
provides XML schema and communication protocols for information exchange
among manufacturing application programs in the web-services environment.
The "Part 1: Core Elements" document especially focuses on information
model of core elements in the production planning and scheduling domain.
Since the elements have been designed without specific contexts in
planning and scheduling, they can be used in any specific type of
messages as a building block depending on the context of application
programs. The "Part 2: Transaction Messages" document especially focuses
on transaction messages that represent domain information in accordance
with the context of the communication, as well as transaction rules for
contexts such as pushing and pulling of the information required. The
"Part 3: Profile Specifications" document especially focuses on
profiles of application programs that may exchange the messages defined
in this standard. The profile shows capability of application programs
in terms of services for message exchange. The profile can be used for
definition of a minimum level of implementation of application programs
who are involved in a community of data exchange.

Generating Semantically Precise XForms Applications
The NIEM is a federal XML-centric metadata standard created for the
precise exchange of documents. Although the scope of many of the NIEM
sub-domains concerns national security issues, the NIEM is successfully
implemented in other domains, such as K-12 education and property
taxation. The NIEM contains a general "upper ontology" that is
applicable to many other domains that deal with concepts such as
activities, documents, organizations, regions (GIS), and persons.
There are many benefits for beginning a Web application with a
controlled vocabulary or metadata registry such as the NIEM. Metadata
registries contain useful information that can be used to create a
consistent set of XML schemas and forms. Using a metadata registry
also forces users to declare early in the application lifecycle exactly
what data elements they will transmit between organizations. This
article demonstrates how XForms applications can be automatically
created from a NIEM constraint schema, and shows how graphical tools
can allow non-programmers to automatically create rich Web applications
using a model-driven approach. It gives an example of how a short XML
transformation (XSLT) is used to achieve this task and how the
transformation can be modified and extended by developers. By using
NIEM XML Schema structure, naming conventions, and additional metadata,
the transformation task is much easier to extend. Although the example
code included in this article will create working forms, its intent
is a starting point to enable non-programmers to create working XForms
applications. A software developer willing to become familiar with
and modify the transformation can facilitate the extension of the
transform to meet specific business requirements. This transform is
just one of the first steps an IT department can adopt to empower
non-programmers to create precise specifications that automatically
generate correct Web forms. This process and many similar processes
like it are part of the declarative revolution that has great potential
to lower overall IT development costs and empowers a much larger
audience to play a direct role in Web development.

ebXML Registry/Repository
The freebXML Registry [OMAR] team is pleased to announce the release of version 3.1 of our royalty-free open source implementation of the ebXML Registry standard [OVERVIEW].
This release culminates more than a year of work and incorporates experience gained from a diverse community of users of freebXML Registry [USAGE].
*Release Contents*
Our latest release provides numerous bug fixes and a few new features. For a detailed list see [RELNOTES].
The new version provides a near, feature complete implementation of Registry Full conformance profile for the OASIS ebXML Registry 3.0 standard [ebRR]. The only missing feature is support for Single Sign On (SSO) based on the Registry SAML Profile. This implementation therefor currently only claims conformance to the Registry Lite profile for the OASIS ebXML Registry 3.0 standard.
The freebXML Registry also provides a feature complete implementation of level 1 conformance profile of the Java API for XML Registries API [JAXR].
