Configuration Management
Working Group
Jim Amsden
Charter

Enable distributed Web authoring
tools to perform
– Versioning
– Parallel Development
– Configuration Management
Put the “V” back in WebDAV
 Represents an expansion of the
original goals to support scaling
across users and content

Versioning

Tracking multiple revisions
 Maintaining predecessor/successor
relationships
 Accessing version history
 Based on a checkout/checkin metaphor
for managing potential update conflicts
Parallel Development

Increases resource availability
 Allows multiple changes to the same
revision at the same time
 Uses merging to reconcile parallel
updates
 Necessary for multi-user, distributed
environments
Configuration Management

Supports tracking and accessing multiple
interrelated resources over time
 Recognizes complex relationships
between Web resources
 Provides a way to specify and manipulate
related resources as a set
In Scope:
Creating versioned resources
 Naming and accessing revisions and
configurations
 Mapping revisions to the URL
namespace
 Creating new revisions
 Parallel development
 History retrieval

In Scope (cont.-)
Merging of revisions and
configurations
 Differencing
 Operations on configurations
 Versioning support for down-level
HTTP and WebDAV clients

Not in Scope:

HTTP server-to-server communication
protocols
Workflow, process and change request
management
Versioning and configuration management
by non-HTTP and WebDAV protocols
