WS-I Promotes Profiles To Final Material Status
The Web Services Interoperability Organization (WS-I) announced the
publication of its Basic Profile 1.1, Attachments Profile 1.0 and Simple SOAP
Binding Profile 1.0 as Final Material. The Final Material designation is
applied to those deliverables that have been formally approved by the WS-I
member community. The profiles address interoperability issues with Web
services attachments and are available for download at www.ws-i.org.
"WS-I understood from its members that existing Web services attachment
specifications were increasingly presenting interoperability difficulties,"
said Chris Ferris, chair of the WS-I Basic Profile Working Group. "The new
profiles provide Web services developers with a flexible mechanism for
creating attachment-enabled applications with predictable interoperability."
Basic Profile 1.1
Basic Profile 1.1 describes how core Web services specifications should be
used together to develop interoperable Web services. Specifically, the
document consists of a set of non-proprietary Web services specifications and
clarifications, refinements, interpretations and amplifications of them that
promote interoperability.
To create version 1.1, the Basic Profile 1.0 was re-architected to relocate
all binding-specific envelope serialization requirements to its own profile;
the Simple Soap Binding Profile 1.0. This new structure enables the Basic
Profile 1.1 to easily compose with any profile that specifies envelope
serialization, including the Simple SOAP Binding Profile 1.0 and the
Attachments Profile 1.0.
With the release of the profiles, Web services that use attachments can be
tested for WS-I conformance with a composition of Basic Profile 1.1 and
Attachments Profile 1.0. Those that do not use attachments can be tested for
conformance with a composition of Basic Profile 1.1 and Simple SOAP Binding
Profile 1.0. A claim of conformance to both the Basic Profile 1.1 and the
Simple SOAP Binding Profile 1.0 will be equivalent to a claim of conformance
to the Basic Profile 1.0 plus the published errata.
Simple SOAP Binding Profile 1.0
SOAP 1.1 defines an XML structure for transmitting messages, called the
envelope. The Simple SOAP Binding Profile mandates the use of that structure
and places certain constraints on its use. Simple SOAP Binding Profile 1.0 is
derived from the Basic Profile 1.0 requirements related to the serialization
of the envelope and its representation in the message.
Attachments Profile 1.0
SOAP Messages with Attachments (SwA) defines a MIME multipart/related
structure for packaging attachments with SOAP messages. This profile
complements the Basic Profile 1.1 to add support for conveying interoperable
SwA-based attachments with SOAP messages.
Next Steps
WS-I is currently working to develop sample applications and testing tools for
use with the newly approved Basic Profile 1.1, Attachments Profile 1.0 and
Simple SOAP Binding Profile 1.0. In addition, at its recent community meeting,
WS-I chartered a new working group, called the XML Schema Work Plan Working
Group, to focus on collecting and understanding interoperability issues
related to the use of XML Schema as the means by which application data is
defined with the intent of determining the most suitable course of action for
WS-I in addressing those concerns.
