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. Recently (12/2002) finalized, not yet widely used but
presumably it will be.

10 December 2002, http://www.w3.org/TR/2002/PR-xmlenc-core-20021003/


XKMS - XML Key Management - Protocols for distributing and managing
public keys, intended for use with XML Signature and Encryption. Work in
progress. Based on XKMS proposal http://www.w3.org/TR/xkms/

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.

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.

currently submitted to any standards body but being implemented
nevertheless by several technology vendors.

Messaging Protocol (WS-ReliableMessaging)", 13 March 2003,

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.

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.

(WSAtomicTransaction), September 2003,
http://ftpna2.bea.com/pub/downloads/ws-at-pub.pdf

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. 

Here is the general OASIS reference:

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..

http://www.ibm.com/developerworks/library/ws-fedact/

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.
