The W3C published last month an update to its "Guide to Versioning XML Languages Using new XML Schema 1.1 features" which details the new features of XML Schema 1.1 in the context of schema versioning. They represent real advances for web service practitioners and should become part of your guidelines and best practices when the W3C releases XML Schema 1.1.
In this presentation recorded at JAOO, IBM's Rod Smith discusses the read/write web, and discusses how the approach known as "Mashups" might be used in enterprise scenarios for "do-it-yourself" IT.
In contrast to Google, who base their public RESTful services on the Atom Publishing Protocol (APP), Microsoft has found the need to go down a different route and has introduced Web3S.
Dara Obasanjo writes about the limitations of the Google Data API (Google's implementation of the Atom Publishing Protocol with some extensions) as a general purpose protocol and explains why Microsoft will not support or standardize on GData.
14 Ruby projects were accepted for the Google Summer of Code bounty program. The projects range from a debugger for Rails, to a project writing an RSpec specification for Ruby, to protocol implementations using EventMachine and Ragel, and more.
Microsoft's Data blog has five short demos on Orcas and post-Orcas features for editing XML files and XSD files, debugging XSLT, and working with Entity Data Models (EDM).
InfoQ has assembled a summary of the features included in the March CTP of Visual Studio Orcas. The Orcas CTP, which is expected to be released as VS 2007, can be downloaded from MSDN.
"Web 2.0" expert Dion Hinchcliffe elaborates on eleven ideas he considers valuable for SOA architects in 2007, most of them connected to merging Web 2.0 and "classical" SOA concepts.
Microsoft has released a preview of it LINQ to XSD technology. Like LINQ to XML, this provides query capabilities for XML documents. The difference here is that while LINQ to XML works over arbitrary XML in a late-bound fashion, LINQ to XSD is strongly typed.
With a very funny blog post that takes a critical look at the history of SOAP, written in the form of a dialogue between a Web services expert and a hypothetical developer, Pete Lacey has started an amazing chain of postings.
InfoQ Ruby editor Obie Fernandez interviews Tim Bray, one of the inventors of XML and current Director of Web Technologies for Sun Microsystems. We cover varied topics such as his opinions about Ruby and Rails, the impact of dynamic languages on web development, static versus dynamic typing, Sun's support of the JRuby project, Atom, and WS-* versus REST approaches to systems integration.
WS-MetadataExchange, the Web service standard that specifies how information about a service's interface, policy, and other metadata can be retrieved at runtime, has been updated to version 1.1.
The WCF RSS Toolkit has been released. The toolkit supports exposing a service as an RSS 2.0 feed, Atom 1.0 feed and SOAP endpoint simultaneously; it can also be extended to support other wire formats. Yasser Shohoud has also blogged some code examples today.
In an article published on Martin Fowler's web site, Ian Robinson describes a new strategy for evolving contract versions in a community of service providers and consumers.
The Java community might soon have a single coherent stack for doing any form of syndication, by merging the efforts and contributions from all the key contributors in the field. Discussions have emerged between the creators of IBM's Atom Reference Implementation code, the ROME community, and others about merging into a new Apache project called Abdera.
