Subject: Re: Request for an agenda item on Tuesday, 14 Feb 2006 to discuss the potential liaison with FWSI TC


We did discuss briefly today - and I noted that we need to re-think call
schedule to allow you to attend.

George volunteered to re-post your PDF top the group - but you just did that
for us!

I'm at the end of my night here - so not enough time to respond to all your
long message.

However - one thing did catch my eye - log files - this is something I'm
right now with Hermes at NIH - and we're slated to switch over to the new
log4j XML
format - and there is also an open source viewer tool for log4j XML logs.

I'd pro-offer - no need to re-invent this wheel - the log4j approach here
seems more
than adequate - and one that people could duplicate from other languages
easily using calls to the log4j jar.

I think our group will be able to give more feedback for you at our next

More to follow...

Thanks, DW

Subject: Request for an agenda item on Tuesday, 14 Feb 2006 to discuss the
potential liaison with FWSI TC

Hi All,

Sorry, I was unable to attend the ebSOA TC Conference Call Today (i.e.
Wednesday, 01 February 2006) 4:00 AM to 5:00 AM Singapore Time.

Kindly, Have u all had a chance to go through our FE Specification in detail
which I mentioned during last ebSOA Biweekly Conference Call (held on
Tuesday, 17 January 2006 - 3:00 PM to 4:00 PM EST) and Also May I know what
u all discussed today on the agenda item 3. Communication with other OASIS

Hence, I would like to discuss with u all the potential liaison of our FWSI
TC with ebSOA TC during the next ebSOA Biweekly Conference Call & ebSOA
Editors Conference Call - Tuesday, 14 Feb 2006.


The FWSI TC has two subcommittees, namely, Functional Elements SC &
Implementation Methodology SC. The Functional Elements SC has come out with
specification for some functional elements like Notification Engine, Log
Utility, Configurable Search, Secure SOAP, EventHandler, Service Management,
etc. that any SOA-based application could make reference and use of.

We would like to further explore the possibilities of liaison with eb-SOA TC
in terms of making use of the following potential functional elements (which
have the two main characterestics - Multi-purpose, Re-usable, and
Distributed, Specialized Components as a Framework) in their

a) Transport (ebXML Message Service v3 0 - SOAP w/ Attachments, etc ),

1. Log Utility

In a Web Service-enabled implementation, the Log Utility Functional Element
can help to organise the diagnostic output that may be generated by the
implementation. In order to achieve that, the following capabilities should
be provided. They include:
* Logging information into different data sources,
* Allowing user defined log format to be used,
* Capability for storing log information, and
* Providing the capability to analyse the information log.

b) Message Reliability and Error Management (ebMS, WS-Reliability),

2. Notification

In a Web Service-enabled implementation, timely information is crucial for
the management of resources that it encompasses. Other uses of this
Functional Element include broadcasting of information to other services and
this could span across both the wired and wireless medium. In order to
fulfill these needs, this Functional Element will cover the following
aspects which include:
* Providing the capability to configure and link with the various gateways
so as to enable messages dissemination, and
* Providing the capability to send instantaneous or scheduled messages to
the intended audiences.

3. Error Management

Error management is an important aspect in any software application
development.  In particular, it is important to know the cause of error in
the Service Oriented Architecture (SOA) environment as an application can
consume any service provided from any domain space spans across the Internet
space.  When an error occurs, it can be from within the same application
domain or from different domain space.  Hence, it is important to know the
system state when the error occurred in the SOA environment.  For example,
when an error occurred, what services were used; which services' interfaces
were used; the passed in parameters and its associated values used for the
interfaces, the time when the error occurred, API or SOAP invocation, etc
are the important information for managing the application in the SOA

4. Event Handler

Information is in abundance in a service-oriented environment. However, not
all information is applicable to a particular enterprise and there lies the
need to control information flow in an organization. In a Web
Service-enabled implementation, the Event Handler Functional Element can
help to fulfill this need by:
* Managing the information flow through a subscription based mechanism,
* Streamlining information into meaningful categories so as to improve
relevancy to a potential consumer of the information, and
* Refining information flow via a filtering mechanism

c) Document Engineering (UBL, SOA Information Model, SOA Collaboration

5. Data Integrator

The Data Integrator Functional element is expected to be used for enabling
easy and simple mechanisms to access disparate data sources by:
* Providing unified data view of enterprise across various data sources,
* Enabling the partitioned view of data for different groups/departments
based on defined logical views, and
* Performing data processing or transformation before presenting the defined
logical data view(s).

d) Registry / Repository, Interface Management and Discovery (ebXML Registry
/ Repository v3 0),

6. Service Registry

In a Web Service-enabled implementation, there exist the needs to maintain a
central repository of all the services that are available. This facilitates
service lookups as well as management of Web Services within the application
that contains the Functional Element. In order to achieve these
expectations, the Functional Element will cover the following aspects.
* Simplify management of information in a XML registry server like UDDI and
ebXML, and
* Simplify information publish and query from a XML registry server like
UDDI and ebXML.

e) Security and Identity Architecture (Dig Sig, SAML, XACML, XML

7. Key Management

The Key Management Functional Element is expected to be related Web Services
security.  To enable Web Services security, cryptographic keys are used for
digital signatures and encryption.  XKMS defines a Web services interface to
a public key infrastructure.  With development of XKMS standard, more and
more PKI providers adopt XKMS to remove its complexity without sacrificing
its benefits.  Application developers will only ever need to worry about
implementing XKMS clients for key management.  As such it will cover aspects
that include.

8. Secure SOAP

In a Web Services implementation, it is envisage that confidential
information is being exchanged all the time. Against this backdrop, it is
imperative that an application in such an environment is equipped with the
capability to guard sensitive information from prying eyes. Secure SOAP
Management fulfills this need by covering the following areas.
* The facility of digitally signing SOAP message,
* The facility of encrypting SOAP message, and
* The capability to generate the original SOAP message after signing or
encrypting the message.

f) Message Format and Metadata (XML, Schema, CCTS), and

9. Transformer

Different applications support different format of files or message.
Sometimes same information needs to be represented in different format in
different use cases.  This element tries to provide a framework to
facilitate transformation between files or messages.

g) Service Management (WSDM):

10. Service Management

The ability to monitor Web Services invocation is crucial towards the
adoption of this technology from the security and performance standpoints.
A security framework should incorporate an authentication and authorisation
mechanism together with an audit trail.  These twin considerations will
serve to discourage resource misuse and in addition, will help to promote
the "pay-as-you-use" concept. Service throughput on the server end is
another important parameter that must be monitored.  Administrators of
services, which are sluggish, should be notified immediately via any
electronic means.
