====================
The following annotated list of specs related to Web services was
originally compiled by Roger Cutler. Paul Denning subsequently added
significantly to the references and organization of the list. The
annotations are one person's opinions of what is going on, and do not
reflect a consensus of the Working Group, the W3C or anybody's
employer. As will be apparent, some of the annotations reflect the
limitations of what I happen to know about.
SOAP - Basic messaging spec for Web services. SOAP 1.1 has been very widely
implemented and is part of the WS-I Basic Profile Version 1.0. SOAP 1.2
went to Recommendation status in June, 2003. It does not seem likely that
SOAP 1.2 will be particularly controversial and major vendors will probably
implement it quickly now that it is a recommendation.

EbMS - EbXML Messaging - transport, routing and packaging of business
transactions. Part of the larger ebXML structure, this spec leverages SOAP
1.1 but adds a number of business-critical capabilities such as security
(roughly at the level of WS-Security, I think) and reliability. EbMS 1.0
was part of the original ebXML package, ebMS 2.0 is a significant
improvement, currently in "final draft" in OASIS (I think). In practice it
appears that much of the industry uptake of ebXML has been essentially ebMS
as opposed to the higher level portions of the ebXML package.

WSDL - Basic Web services description spec. WSDL 1.1 has been very widely
implemented and is part of the WS-I Basic Profile Version 1.0. WSDL 1.2 is
being developed in the W3C and is in a "middle" stage of the process. There
does not seem to be any particular competition to WSDL 1.2 in other
standards organizations and major vendors will probably implement it
quickly once it becomes a recommendation (which will take a while).

EbCPPA - EbXML Collaboration Protocol Profile and Agreement - The
Collaboration Protocol Profiles (CPPs) and Agreements (CPAs) which define a
business partner's technical capabilities to engage in electronic business
collaborations with other partners, and the technical agreement between two
or more partners to engage in electronic business collaboration. Version
1.0 was part of the original ebXML package, version 2 has significant
upgrades and was ratified Dec, 2002. Although the CPP/CPA framework seems
very business oriented, I do not know of many (or any, to be honest)
examples of it being used in production.

UDDI (Universal Description, Discovery, and Integration)- Web services
registry. Version 2 adopted 4/2003 has been implemented by a number of
vendors. Version 3, under development, includes new features like
subscriptions/notification, support for digital signatures, keys assigned
by publishers rather than registry providers (which may facilitate the
development of federation), better support for copying of registry entries
between non-replicated registries. UDDI v3 specifies Schema Centric
Canonocalization when using digital signatures. Implementation of UDDI on
the internet has stalled but there is widespread interest in using UDDI in
corporate intranets.

AS2 - Probably best viewed as an alternative to Web services, AS2 is a
draft spec from the IETF. It has not made it completely through the IETF
process, but it appears to be relatively stable nonetheless. It provides
basic but non-extensible security and reliability features for a payload
that may be a binary file (typically an old fashioned EDI file) or XML. AS2
seems to be appropriate for simple transactions, particularly those that
can be performed synchronously, but may not lend itself to more elaborate
scenarios. WalMart has provided a huge boost to AS2 implementation by
requiring in order to do EDI business with them. See, for example,
discussions in product offerings from Isoft and Sterling Commerce.
XML Signature - Digital signature for an XML document, providing proof of
data integrity, message and user authentication. Used by WS-Security and
ebXML security. This is a mature, widely used spec.
W3C, XML-Signature Syntax and Processing - W3C Recommendation, 12
February 2002, http://www.w3.org/TR/xmldsig-core/
XML Encryption - Digital encryption of documents or portions of documents.

WS-CHOR - Web Services Choreography WSCI, from Sun and others (not MS/IBM),
was a major submission but the working group has received other submissions
and has moved significantly beyond WSCI. Describes the flow of messages
exchanged by a Web Service participating in choreographed interactions with
other services. Considerable overlap with BPEL, but more declarative and
oriented toward message sequencing rather than process description. WS-CHOR
is intended to be a language that allows machines to figure out how to use
Web services, BPEL focuses on how to control Web services. (See also
http://xml.coverpages.org/bpm.html)

BPEL - Web Services Business Process Execution Language business process
execution language which form the necessary technical foundation for
multiple usage patterns including both the process interface descriptions
required for business protocols and executable process models. Based on
BPEL4WS submission from Microsoft, IBM and BEA. WSFL (IBM) and XLANG
(Microsoft) were earlier efforts. Considerable overlap with Web Services
Choreography, but more process oriented. See above.

ebBPSS - ebXML Business Process - Representation and model compatible with
an underlying generic metamodel for business processes, activities, and
collaboration. This is the ebXML version of choreography, and I think it is
simpler than either WS-CHOR or BPEL. Version 1.001 was part of the original
ebXML package, and I think that an OASIS TC is just now in the process of
starting up to work on enhancements. I am not aware of any significant
applications of ebBPSS.
OASIS-UN/CEFACT, ebXML Business Process Specification Schema
(BPSS), Version 1.01, 11 May 2001, http://www.ebxml.org/specs/ebBPSS.pdf
WS-Security Construct secure SOAP message exchanges, including provision
for multiple security tokens for authorization and authentication, multiple
trust domains, multiple encryption technologies and end-to-end
message-level security (not just transport-level security). Out of scope:
multiple message exchanges, key exchange, establishing and maintaining
trust. WS-Security defines two core capabilities: 1- how to use
XML-Signature and XML-Encryption with SOAP messaging. It specifies how to
pass signatures and key information in a SOAP header. 2- how to pass
security tokens with a SOAP message. WS-Security supports a variety of
security tokens (each defined by its own binding specification), such as
userid/password, X.509 certificates, Kerberos tickets, and SAML tokens. The
WS-Security TC is just starting in OASIS, but major vendors (MS, IBM) have
already implemented the submitted spec.

SAML Security Assertion Markup Language. Exchanging authorization and
authentication information. Version 1.0 finalized 11/2002. SAML defines
three core capabilities: 1- how to represent security tokens in XML. These
tokens are called assertions, and SAML defines three types of assertions --
authentication, authorization, and attributes. (attributes provide
qualifying information that constrain the other assertions -- such as
spending limits or timing constraints). An assertion is made by some type
of trust authority. 2- a process model for obtaining security tokens from a
trust authority. This includes a set of protocols for accessing a trust
authority. SAML defines two types of trust authorities: Policy Decision
Points (PDPs) and Policy Enforcement Points (PEPs). SAML has defined
bindings for multiple protocols, including SOAP/WSDL. 3- a set of protocol
bindings for conveying SAML tokens. SAML 1.1 defines how to pass SAML
tokens for browser applications. It does not define bindings for how to
pass SAML tokens in SOAP messages -- that is left to WS-Security. It
appears that this spec may be getting some real traction in terms of
practical implementations. See, for example, this auto industry implementation.

Reliable Messaging: A protocol that allows messages to be delivered
reliably between distributed applications in the presence of software
component, system, or network failures by implementing an acknowledgement
infrastructure. There are two major specs that differ in some technical
respects but which by and large implement the same type of functionality:
- Web Services Reliability - OASIS TC. Based on WS-Reliability submission
from Oracle, Sun and others.
Fujitsu/Hitachi/Oracle/Sonic/Sun, Web Services Reliability
(WS-Reliability) Ver1.0, 8 Jan 2003, http://www.sonicsoftware.com/wsreliability
- WS-ReliableMessaging from BEA Systems, Microsoft, IBM, Tibco. Not
currently submitted to any standards body but being implemented
nevertheless by several technology vendors.

Protocol (WS-ReliableMessaging)", 13 March 2003,
http://msdn.microsoft.com/ws/2003/03/ws-reliablemessaging/
XACML XML Access Control Markup Language Fine-grained access control to
XML documents, including by element, sub-tree, temporal, data dependent and
so on. Here is a brief introduction to XACML. XACL from IBM, was one of the
major submissions for this spec but there were a number of others and XACML
differs substantially from XACL. Spec finalized 2/2003.

1.0, OASIS Standard, 18 February

WS-Transaction Framework - WS-Transaction and WS-Coordination were
originally released by IBM, Microsoft and BEA along with BPEL4WS. These
specifications have recently been updated and revised. The latest set of
specifications for the WS Transaction Framework, published by the same
authors, include an updated WS-Coordination spec, WS-AtomicTransaction
which replaces part 1 of WS-Transaction, and WS-BusinessActivity (still to
be published) which replaces part 2 of WS-Transaction. WS-Coordination
defines the protocols for creating activities, registering in activities,
and transmitting information to disseminate an activity.
WS-AtomicTransaction defines the Atomic Transaction coordination type,
which is appropriate to use when building applications that require a
consistent agreement on the outcome of a short-lived distributed activity,
where strong isolation is required until the transaction completes.
WS-BusinessActivity defines the Business Activity coordination type, which
is appropriate to use when building applications that require a consistent
agreement on the coordination of a distributed activity, where strong
isolation is not feasible, and application-specific compensating actions
are used to coordinate the activity. It appears to me that the
WS-Transaction Framework and the Web Services Composite Application
Framework (described below) are playing in more or less the same space and
are not obviously compatible. That is, that they are in competition.

Web Services Composite Application Framework (WS-CAF) - WS-CAF defines a
generic framework for applications that contain multiple services used in
combination (composite applications). It specifies interoperable mechanisms
to set the boundaries of an activity (such as start/end, or
success/failure), to create, access and manage context information, and to
inform participants of changes to an activity. And it supports a range of
transaction models, including simple activity scoping, single and two phase
commit ACID transactions, and recoverable long running activities. The
WS-CAF suite includes three specs published by Arjuna, Fujitsu, IONA,
Oracle and Sun: Web Service Context (WS-CTX ) a lightweight framework for
simple context management, Web Service Coordination Framework (WS-CF) a
sharable mechanism that manages context augmentation and lifecycle, and Web
Services Transaction Management (WS-TXM) which comprises three distinct,
interoperable transaction protocols that can be used across multiple
transaction managers.

WS-Policy is a grammar for specifying Web services policy assertions such
as authentication schemes, transport protocol selection, privacy policy,
QoS characteristics. Another Microsoft, IBM, BEA spec, not submitted yet to
any standards body.

WS-Addressing - provides transport-neutral addressing for Web services that
work through firewalls, gateways, etc. Another spec from MS/IBM/BEA, it
apparently replaces WS-Routing. I don't think it has been submitted to any
standards body.
BEA/IBM/Microsoft, Web Services Addressing (WS-Addressing), 13
March 2003, http://msdn.microsoft.com/ws/2003/03/ws-addressing/
WS-Federation - A spec for standardizing the way companies share user and
machine identities among disparate authentication and authorization systems
spread across corporate boundaries. Developed by IBM/MS/BEA/RSA, I think it
is at least partly in competition with the ID-WSF from the Liberty
Alliance, discussed below..

SPML - Service Provisioning Markup Language
–http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=provision -
framework for exchanging information between provisioning service
points. Provisioning refers to what happens, for example, when a new
employee shows up and changes are required in corporate LDAP, HR database
and so on. This spec does not seem particularly controversial, but there
also doesn’t seem to be a whole lot of interest in it, although it has
apparently been implemented in the catalyst industry.
ID-FF - IDentity Federation Framework, from the Liberty Alliance. Defines
an architecture for providing federated network identity that enables
single signon functionality for a user to multiple service providers.
Liberty is a major consortium that does not include MS or IBM, and the
products are more or less in competition with varioius WS-* specs. I think
that ID-FF is more or less along the same lines as WS-Policy. Submitted to
OASIS.
ID-WSF - IDentity Web Services Framework - Another spec from the Liberty
Alliance, it builds on ID-FF and provides a framework for identity based
web services in a federated network identity environment. I believe that
ID-WSF is pretty much in the same space, and incompatible with,
WS-Federation. Detailed comparison is beyond the scope of this document,
but it appears that both have a number of components for which there is no
comparable function in the other, with Liberty possibly being the more
fully developed. In addition, they have made different technology choices
for similar functions (e.g. ID-WSF Discovery Services vs UDDI for
WS-Federation.
WSRP - Web Services for Remote Portlets - Intended to provide "plug-n-play"
for portals and other apps that aggregate content. Recently adopted as an
OASIS standard, the players in the interop testing include BEA, IBM and
Oracle. Microsoft, Sun and many others participated in the TC. This spec
seems to have wide industry participation, but I have no idea how soon to
expect implementation.
