Hi All,
Passing along some SOA-RM news: "IDS Scheer Supports OASIS Reference
Model" (see below, a few pages down). If anyone needs more details on
this support of SOA-RM by ARIS, I have some contacts at IDS Scheer (one
is sitting next to me right now at a client site) who can connect you to
the folks behind this.

Web Security Experience, Indicators and Trust: Scope and Use Cases Tyler
Close (ed), W3C Working Group Note
W3C has announced an update from the Web Security Context Working Group
in the form of a published Note "Web Security Experience, Indicators and
Trust: Scope and Use Cases." Web user agents are now used to engage in a
great variety and number of commercial and personal activities.
Though the medium for these activities has changed, the potential for
fraud has not. The W3C Web Security Context Working Group, as part of
the Security Activity, was chartered to recommend user interfaces that
help users make trust decisions on the Web. The updated Note explains
the group's technical aims, complementing the WG charter. It explains
what the group aims to achieve, what technologies may be used, and how
proposals will be evaluated. This elaboration is limited to the group's
technical work and does not cover additional activities the group
intends to engage in, such as ongoing outreach and education. The work
outlined in the document is expected to take existing standards and best
practices into account; where relevant, such existing work will be
leveraged. (1) Security information within the Working Group's scope
will be catalogued, along with corresponding presentations and user
interpretations reported in user studies. (2) Members will analyze
common use cases to determine what security information the user needs
to safely accomplish their current task and recommend security
information that should, or should not, be presented in each case. (3)
The WG will recommend a set of terms, indicators and metaphors for
consistent presentation of security information to users, across all web
user agents. For each of these items, the Working Group will describe
the intended user interpretation, as well as safe actions the user may
respond with in common use cases. (4) Group members will recommend
presentation techniques that integrate the consumption of security
information by the user into the normal browsing workflow.
Presenting security information in a way that is typically ignored by
the user is of little value. (5) The Working Group will recommend
presentation techniques that mitigate deceptive imitation, or hiding, of
the user agent's presentation of security information.

Improving Performance of Healthcare Systems with SOA Girish Juneja,
Blake Dournaee, et al., InfoQueue
Healthcare organizations today are challenged to manage a growing
portfolio of systems. The cost of acquiring, integrating, and
maintaining these systems are rising, while the demands of system users
are increasing. Organizations must address evolving clinical
requirements as well as support revenue cycle and administration
business functions. In addition, demands are increasing for
interoperability with other organizations to regionally support care
delivery. Service oriented architecture offers system design and
management principles that support reuse and sharing of system resources
across the healthcare organization. SOA does not require the
re-engineering of existing systems. With SOA, existing processing can be
combined with new capabilities to build a library of services that are
used as a part of solutions. Using shared services that are aligned with
business processes, SOA strengthens interoperability while reducing the
need to synchronize data between isolated systems.
Services may be made available, no matter their location, to create
solutions that reach beyond the desktop, the department, and the
healthcare organization.

Services-Based Enterprise Integration Patterns Made Easy, Part 2 Waseem
Roshen, IBM developerWorks
This serial article presents some of the central concepts and features
of enterprise integration patterns, introducing several basic concepts
and features involved in Service-Oriented Architecture (SOA). Part 1 and
Part 2 of this series describe the basic concepts essential for
understanding a services-based integration pattern. These concepts
include loose coupling, code reuse and layering, language and platform
independence, language independent interface, the idea of discovering a
remote object at run time, invoking methods remotely, and asynchronous
messaging for scalability. To improve on RPC functionality, two methods
are used: (1) Distributed objects, also known as the Object Request
Broker (ORB): This approach focuses on code reuse and language
independence. (2) Asynchronous messaging: This approach addresses the
problem of tight coupling between applications. In addition to
introducing the benefits of object orientation, such as inheritance,
polymorphism, and encapsulation, CORBA introduced a number of new
features. Probably the most important was the concept of ORB, which
extracted the code for marshaling input and output arguments and the
code for communication from the client and server applications into a
separate software component. In addition, ORB provides a facility to get
a reference to a remote object so that methods can be invoked on that
remote object. This separation let the same code be reused by many
applications and allowed a certain amount of decoupling between the
applications by moving away from point-to-point integration. This move
away from point-to-point integration may be considered the first step in
the evolution of the concept of ESB. A parallel development based on
asynchronous messaging contains the seeds for the development of another
type of ESB. This type of ESB provides a more scalable solution than the
ESB type based on ORB. In asynchronous messaging, the client or client
object sends a message to the target application, but doesn't wait for
the response to continue its work. This leads to a certain amount of
decoupling between the applications involved.
Thus asynchronous messaging may be employed as the integration basis if
high transaction volumes are expected. In messaging, the applications
don't communicate with each other directly and don't have a dedicated
communication link established between them. Instead, they communicate
indirectly through queues. A central message broker can receive messages
from different applications, determine the correct destination for each
message type, and route the message to the appropriate destination
application. This lets applications communicate with each other without
knowing the location of the receiving applications.

Surveys from BPTrends and BEA Reflect on 'The State of BPM in 2008'
Jean-Jacques Dubray, InfoQueue
In the past couple of weeks, two major reports on "The State of BPM in
2008" were published. The first one (54 pages) was based on a survey
filled by 274 respondents and published by Paul Harmon and Celia Wolf,
Executive Editor and Publisher of BPTrends.com. The second one
(36 pages) was based on analyst reports, articles and a survey of
customers and was published by BEA with Sandy Kemsley as a co-author.
BPTrends reports that a wide variety of process standards are being used
by the respondents. However, BPMN shows the strongest momentum with 41%
(from 22% in 2006) and BPEL showing a modest progression with 26 % (from
23% in 2006). XPDL (6%) and the OMG Process Metamodel
(7%) are far behind while UML (30%) and CMM/CMMI (28%) remain fairly
stable. The most popular tools to capture business processes remained
Visio and PowerPoint. The respondents deployed a wide spectrum of BPMS
suites with a prominence of the leading SOA infrastructure
vendors: IBM (including FileNet), SAP, and Oracle.

Extensible Resource Identifier (XRI) Resolution Version 2.0 Gabe Wachob,
Drummond Reed (et al., eds), OASIS Committee Draft
OASIS announced the release of an approved Committee Draft 03 of
"Extensible Resource Identifier (XRI) Resolution Version 2.0" for
fifteen-day public review 26-March-2008. The Relax-NG schema files
referenced normatively in the prose specification document are also
available separately. Extensible Resource Identifier (XRI) provides a
uniform syntax for abstract structured identifiers. Because XRIs may be
used across a wide variety of communities and applications (as Web
addresses, database keys, filenames, object IDs, XML IDs, tags, etc.),
no single resolution mechanism may prove appropriate for all XRIs.
However, in the interest of promoting interoperability, this
specification defines a simple generic resource description format
called XRDS (Extensible Resource Descriptor Sequence), a standard
protocol for requesting XRDS documents using HTTP(S) URIs, and standard
protocol for resolving XRIs using XRDS documents and
HTTP(S) URIs. Both generic and trusted versions of the XRI resolution
protocol are defined (the latter using HTTPS (RFC 2818) and/or signed
SAML assertions. In addition, an HTTP(S) proxy resolution service is
specified both to provide network-based resolution services and for
backwards compatibility with existing HTTP(S) infrastructure.
Resolution is the function of dereferencing an identifier to a set of
metadata describing the identified resource. For example, in DNS, a
domain name is typically resolved using the UDP protocol into a set of
resource records describing a host. If the resolver does not have the
answer cached, it will start by querying one of the well-known DNS root
nameservers for the fully qualified domain name. Since domain names work
from right to left, and the root nameservers know only about top level
domains, they will return the NS (name server) records for the top-level
domain. The resolver will then repeat the same query to those name
servers and 'walk down the tree' until the domain name is fully resolved
or an error is encountered. A simple non-recursing resolver will rely on
a recursing nameserver to do this work. For example, it will send a
query for the fully qualified domain name docs.oasis-open.org to a local
nameserver. If the nameserver doesn't have the answer cached, it will
resolve the domain name and return the results back to the resolver (and
cache the results for subsequent queries). XRI resolution follows this
same architecture except at a higher level of abstraction, i.e., rather
than using UDP to resolve a domain name into a text-based resource
descriptor, it uses HTTP(S) to resolve an XRI into an XML-based resource
descriptor called an XRDS document.

IDS Scheer Supports OASIS Reference Model, ARIS SOA Architect Staff, IDS
Scheer Announcement
IDS Scheer has announced support for the OASIS SOA Reference Model used
in tandem with ARIS SOA Architect. The structure and management of a
business process-oriented service landscape requires close cooperation
between specialized departments and IT within companies. IDS Scheer has
leveraged its expanded methodology for Business-Driven SOA into
developing comprehensive support for describing, planning and managing
services -- designed specifically for this type of collaboration within
an organization. The new methodology, based on the OASIS SOA Reference
Model, categorizes services using business criteria with a concentration
on those with the greatest strategic importance -- the end result is
mitigation of risks within SOA projects. SOA projects are designed to
help companies become more flexible to react efficiently to changes in
the market. With the new reference model, these projects can now be
achieved directly without moving from pillar to post because the
development and management of the services work in conjunction with the
relevant business unit. The technical specification of individual
services within a SOA is a new feature and it ensures the continuing
provision of target-oriented service development in IT and subsequent
service reuse. This methodology is fully integrated into ARIS SOA
Architect. Existing models for describing IT landscapes and web services
can be reused, thus securing investments and enabling service
orientation and Enterprise Architecture measures to work together. ARIS
SOA Architect reduces implementation costs considerably because
redundant implementations within a service are compiled, thereby
producing an efficient service architecture. If a service fails,
alternative implementations can be identified with ease.

NETCONF Configuration Interface Advertisement with WSDL and XSD Hideki
Okita, Tomoyuki Iijima (et al., eds), IETF Internet Draft
Members of the IETF Network Configuration (NETCONF) Working Group have
released "NETCONF Configuration Interface Advertisement with WSDL and
XSD" as an updated I-D. This IETF Working Group has created the NETCONF
protocol as a standard configuration protocol between a network
management system and network devices. By using this unified
management/configuration protocol, operators can reduce management/
configuration cost. The updated memo describes a configuration interface
advertisement method for NETCONF device developers. In the proposal, the
developers take a configuration interface definition information of
target NETCONF devices. On their development environment, they generate
stab classes to control the devices. The NETCONF device advertises their
configuration interface by a WSDL file. The WSDL file describes message
type of each NETCONF operation of the device.
The WSDL file contains XML Schema in its types element and describes
definition of the types definition used to configuration data. By this
configuration interface advertisement, Network management System
(NMS) developers can improve their development efficiency of the NMS.

Mozilla's Firefox 3, Beta 4 Faster, Touts UI Changes, Vista Integration
Larry Dignan, ZDNet News
Mozilla says that the fourth beta of its Firefox 3 browser is available
to download with more than 900 enhancements, better handling of memory
and interface tweaks for Vista. Among the key features: (1) Improved
memory usage: Mozilla says 'several new technologies work together to
reduce the amount of memory used by Firefox 3 Beta 4 over a web browsing
session. Memory cycles are broken and collected by an automated cycle
collector, a new memory allocator reduces fragmentation, hundreds of
leaks have been fixed, and caching strategies have been tuned.' (2) More
personalization -- via an algorithm in the location bar that tracks site
visit (visit recency and frequency); the aim is to better match URLs
with your history and bookmarks; the algorithm adapts to your browsing
habits; (3) Better search support in the download manager; (4) Full page
zoom allows you to scale layout, text and images; (5) Integration with
Vista and specific icons to go along with it; integration with Mac OS
and Linux too; (6) Support for offline data storage for Web
applications; (7) Tweaks to the JavaScript engine: the optimization
resulted in significant gains over previous releases in the popular
SunSpider test from Apple, web applications like Google Mail and Zoho
Office run much faster, and continued improvements to memory usage
drastically reduce the amount of memory consumed over long web browsing
sessions.
