So, you're saying we have a working draft of a proposal for a standard for
proposing working drafts, proposals, and standards? ;-)

> Things we need to track:
>
> Specification Document Version - (IPP 1.0, IPP 1.1, PSI 1.0,
> PSI 1.1, etc) Specification Document Revision - (Date?)
> Specification Goodness - (3 states, with ability to
> differentiate a document that has just been published from
> one that has been accepted)
> - States: (a) Draft, (b) Proposal, (c) Standard
> - Acceptance: (1) Working, (2) Accepted
> Individual Interface Version - (0.01 - 0.99, 1.0.0, 1.0.1,
> 1.0.2, 1.0.3, 1.1.0, 1.1.1, 1.1.2, etc) Individual Interface
> Revision - (1, 2, 3, 4, 5...) Individual Interface Namespace
> - (?) Schema Revision - (0.01 - 0.99, 1.0.0, 1.0.1, 1.0.2,
> etc) Schema Namespace - (?)
>
> Requirements:
> Published WSDL and Schema needs to remain accessible.
> A Specification Document should be able to refer to different
> Interface Revisions. (i.e. 1.1 of the PSI Specification
> should be able to reference QueryEndPointsInterface v1.0.5 if
> we don't need to change it for 1.1)

> Versioning
> Everyone who developed COM applications: How many of you
> remember the golden rules of versioning? Okay, hands down. As
> a quick review, here are the
> rules:
> 1. Always increment the version number.
> 2. Freeze the interface on the previous version. All new features
> should go into a new interface.
> 3. Freeze all structures used on the previous version. Any
> enhancements
> to those structures should show up in new structures.
> WSDL version indication is done via the targetNamespace
> attribute of the definitions element. This namespace gives
> the SOAP messages meaning by relating the messages to a
> specific bit of code implemented somewhere on the server. The
> targetNamespace attribute has an XSD type of anyURI. This
> attribute could be used in a large number of ways to indicate
> the version. For a service named Foo that was hosted at
> msdn.microsoft.com, a few options exist for the first
> version. Option 1: The targetNamespace could be named
> http://msdn.microsoft.com/foo. This works by giving the
> interface a unique namespace name. This option does not fit
> our needs, however, because it does not include an obvious
> mechanism for indicating whether one version is earlier or
> later than another. I suppose you could follow up later
> versions of the interface with namespaces such as
> http://msdn.microsoft.com/foo1 and
> http://msdn.microsoft.com/foo2, but that seems silly. Option
> 2: The targetNamespace could be named
> http://msdn.microsoft.com/1.0/foo.
> Again,
> this gives the interface a unique namespace identifier. This
> option fits our needs, because it gives us an obvious
> indicator of version as well as a place to increment that
> version in a way people are used to seeing. As we are dealing
> with an XML-centric world, however, we might do well to
> follow the lead of the newer XML specifications, such as SOAP
> 1.2, XML Schema, and XSLT. While this option is viable, it
> does not follow this lead. Option 3: Call the targetNamespace
> http://msdn.microsoft.com/2002/04/foo. > This has a few small
> advantages over option 2. For one, this is the versioning
> scheme employed by the newer XML specifications. People who
> are used to looking at XML will find versioning by date more
> familiar. As an added bonus, versioning by date allows a
> person or machine to easily figure out when the version was
> released. You can increase the resolution of the version to
> reflect the frequency of releases. A resolution down to the
> hour would indicate that releases are coming out far too
> frequently. If your team does nightly builds, extend the
> interim granularity of the version to the date of the build.
> Regardless of what you do, don't be cute and use zero-based
> month and day-of-month numbers. It's counterintuitive. Of the
> above options, both 2 and 3 fit the bill, with 3 being the
> versioning option that many XML users I have talked to like
> the best. An added advantage of date-based versioning is that
> you will know how long the interface has been available. When
> changing an XSD type, create a brand new type in a brand new
> namespace. This new namespace should still stick with your
> versioning model. If the first version was in a namespace
> such as http://foo.org/bar/2001/11/20/types, the new
> namespace should only change the date information. That new
> type, if published on April 5, 2002, should be in the
> namespace http://foo.org/bar/2002/04/05/types. Any related
> sub-types should remain in the old namespace and simply get
> imported into the new one. Here, no wishy-washy answers. To
> sum things up, here are the guidelines to use when updating an
> interface:
>
> * The changes always go into a new namespace.
> * The new interface should be a superset of the old one.
> * It is a good idea to keep the data model the same when
> versioning
> the interface.
> * Never revise data structures. Instead, add new ones as needed.
