View source for EMF/CDO 1.0/New and Noteworthy

CDO 1.0 (available as part of [http://www.eclipse.org/ganymede/ Ganymede] and also separately on the [http://www.eclipse.org/modeling/emf/ EMF] site) contains a number of important and long-awaited features, changes, and enhancements. 
<br>
<br>

==Model Integration Features==
* EMF integration at model level (as opposed to the edit level)
* Supported model types:
** Generated models (just switch two .genmodel properties)
** Dynamic models (just load .ecore file and commit to repository)
** Legacy models (for compiled models without access to .genmodel)
** Ecore meta meta model and descendants
<br>

==User Interface Features==
* Eclipse view for working with CDO sessions, transactions, views and resources
* Package Manager dialog per session
* Eclipse editor for working with resources and objects
<br>

==Client Side Features==
* Multiple sessions to multiple repositories on multiple servers
* Multiple transactions per session
* Multiple read-only views per session
* Multiple audit views per session (an audit is a view that shows a consistent, historical version of a repository)
* Multiple resources per view (a view is always associated with its own EMF ResourceSet)
* Inter-resource proxy resolution
* Multiple root objects per resource
* Object state shared among all views of a session
* Object graph internally unconnected (unused parts of the graph can easily be reclaimed by the garbage collector)
* Only new and modified objects committed in a transaction
* Transactions can span multiple resources
* Demand loading of objects (resources are populated as they are navigated)
* Partial loading of collections (chunk size can be configured per session)
* Adaptable pre-fetching of objects (different intelligent usage analyzers are available)
* Asynchronous object invalidation (optional)
* Clean API to work with sessions, views, transactions and objects
* CDOResources are EObjects as well
* Objects carry meta information like id, state, version and life span
* Support for OSGi environments (headless, Eclipse RCP, ...)
* Support for standalone applications (non-OSGi)
<br>

==Network Protocol Features==
* [[Net4j]] based binary application protocol
* Pluggable transport layer (shipped with NIO socket transport, polling HTTP and JVM embedded transport)
* Pluggable fail over support
* Pluggable authentication (shipped with challenge/response negotiation)
* Multiple acceptors per server
<br>

==Server Side Features==
* Pluggable storage adapters
** See [[#DB Store Features|DB Store Features]]
** See [[#Hibernate Store Features|Hibernate Store Features]]
** Objectivity support coming soon
** Native memory storage adapter
* Multiple repositories per server
* Multiple models (packages) per repository
* Multiple resources (instance documents) per repository
* Expressive XML configuration file
* Configurable storage adapter per repository (see below)
* Configurable caching per repository
* Clean API to work with repositories, sessions, views, transactions and revisions
* Support for OSGi environments (usually headless)
* Support for standalone applications (non-OSGi)
<br>

==DB Store Features==
* Supports all optional features of the [[#CDO Server|CDO Server]]
* Pluggable SQL dialect adapters
* Includes support for Derby, HSQLDB, MySQL and Oracle (TBD)
* Pluggable mapping strategies
* Includes horizontal mapping strategy (one table per concrete class)
* Includes vertical mapping strategy (TBD, one table per class in hierarchy)
* Supports different mapping modes for collections
<br>

==Hibernate Store Features==
* Integration with EMF Teneo
* Supports most of the Teneo features. See [[EMF/Teneo_1.0/New_and_Noteworthy|Teneo New and Noteworthy]]
<br>

==More information==

The CDO project uses dynamically-generated [http://www.eclipse.org/modeling/emf/news/relnotes.php?project=cdo&version=HEAD release notes], using Bugzilla and CVS data to create accurate lists of bugs closed in each build. This also allows developers and users to see [http://www.eclipse.org/modeling/emf/searchcvs.php?q=project%3A+org.eclipse.emf+days%3A+7 what files were changed] for each bug, by who, and when. For details on how this is done, see [[Search CVS#Parameter_List | Parameter List]].
