-# Working with CDO Model Repositories
-This document is a brief guide to getting started with Papyrus UML models in the CDO Model Repository.
-
-For more information about CDO, see the [EMF CDO wiki](http://wiki.eclipse.org/CDO).
-
-## <a id="Installing">Installation</a>
-The CDO Model Repository integration feature is not installed by default with Papyrus; it is an optional extra component.  To install this feature, open the Papyrus discovery wizard from the **Help &rarr; Install Papyrus Additional Components** menu.  You should find an entry like the following in the list:
-
-![Install additional components](discovery_dialog.png)
-
-Select the CDO integration feature by checking the box on the left side and press **Finish** to perform the installation.
-
-## <a id="Connecting">Connecting to a Repository</a>
-Repository connections are managed in the **CDO Repositories** view.  Use the green plus (**+**) button in the view to create a new repository connection:
-
-![Add repository](addrepo.png)
-
-The new repository is then added to the view.  Select the new repository and pick **Checkout** in the context menu.  Complete the wizard.  A new checkout representing the contents of the repository now appears in the **Project Explorer** view.  Note that this checkout looks like a workspace project but does not physically exist in your workspace.  An online checkout does not store model data on your local disk at all; an offline checkout stores the checked-out baseline locally (but not in the workspace).  You can create as many checkouts from a repository as you want, for example when working with different branches.
-
-Creating new or opening existing Papyrus models in a checkout works similar to local workspace projects.  Note that because it is necessary to explicitly connect to model repositories, any model editors that are open when shutting down the Papyrus workbench are not re-opened on next launch.
-
-## <a id="Importing">Importing Models from the Workspace</a>
-
-You probably already have models in your workspace that you would like to import into a repository.  To do this, select one or more models in the **Project Explorer** and choose the **Import into Repository...** action in the context menu.  Alternatively, just drag and drop one or more model onto a repository.
-
-![Import Models](importmodels.png)
-
-By default, the wizard maps incoming models to paths in the repository according to their paths in the workspace.  This mapping may be customized in the last page.
-
-As a first step, the wizard analyzes the selected models for cross-reference dependencies.  It is highly recommended also to import any models that references the initially selected models.  Otherwise, they will be updated to reference the models in the repository and it may be difficult to edit them when Papyrus is not connected to the repository.
-
-It is also suggested to import models referenced by the initial selection.  However, references from models in a repository to models in the workspace do not present the same kind of problem of availability as the reverse case.
-
-## <a id="Validating">Validating Models</a>
-
-The **Validate** context menu actions work in repository models just as in workspace models.  Annotations are presented in the diagrams and in the **Model Explorer** view.  The difference is that validation issues are not shown in the **Problems** view.  Instead, they are shown in a new **Model Validation** view:
-
-![Model Validation](validation.png)
-
-The **Model Validation** view supports the usual functions, including:
-
-* double-click navigation to the problem element in the editor
-* copy selected problems to CSV text on the system clipboard
-* delete problems
-

-# Sharing Models with a Team
-One purpose of keeping Papyrus models in a CDO model repository is to share them with a team and enjoy the benefits of real-time collaboration that CDO offers.  However, this entails certain consequences that need to be accounted for in the workflow.
-
-## <a id="Locking">Locking Objects</a>
-The context menu in both the **Model Explorer** view and the diagrams has actions for locking and unlocking objects.  Locking a model element reserves it for the exclusive use of the editor that has it locked.  Other users connected to the same repository cannot edit it.  Locking an element in a diagram locks not only the model element, but also the view of it in the diagram.
-
-An object locked by you shows a key decoration.  To lock an element, use the **Locks/Conflicts &rarr; Lock** context menu action:
-
-![A locally locked element](locked.png)
-
-To unlock an object once you have finished editing it and saved the model, use the **Locks/Conflicts &rarr; Unlock** context menu action.  Locks are also automatically released when the editor that holds them is closed.
-
-When another user has locked an element, the editor shows a lock decoration:
-
-![A remotely locked element](remotely_locked.png)
-
-Note that in this case, the element cannot be edited:  the **Properties** view is disabled and the diagram editor does not show the selection handles.
-
-## <a id="Conflicts">Handling Conflicts</a>
-CDO is a real-time collaborative editing platform.  When other users save changes they have made in models that are open in your Papyrus workbench, the repository server pushes those changes into your editors.  You see those changes in real time.  There is no "synchronize" step as with Git or Subversion source control.
-
-Most changes saved by other users will be in different model elements and diagram views than those in which you have unsaved changes.  These do not present a problem.  However, the repository may push changes in objects that you *have* edited and have not yet saved.  Many of these changes, too, are automatically merged by Papyrus:  changes to features of an object that you have not modified and certain changes in multi-valued features can be merged automatically.  Other changes leave the objects that you have edited in a state of conflict.  This is indicated by a decoration in the diagrams and the **Model Explorer** view:
-
-![Conflicting changes](conflict.png)
-
-Papyrus cannot automatically resolve these conflicts by merging the incoming changes from the repository with the changes made in your editor.  They require manual intervention to resolve.
-
-On an object that shows conflict, invoke the **Locks/Conflicts &rarr; Resolve Conflicts** context menu action.  In the current release, the only strategy available is to rollback the editor's unsaved changes, leaving only the changes pushed by the server from other users.  Future releases will add more options, such as an interactive graphical merge.

+#Now you can work according to your Papyrus habits
+
+''Note'': The commit on the CDO server is automatically done by the standard save action (CTRL-S).
+
+
+==How to import Models from the Workspace==
+
+You probably already have models in your workspace that you would like to import into a repository.  To do this, select one or more models in the '''Project Explorer''' and choose the '''Import into Repository...''' action in the context menu.  Alternatively, just drag and drop one or more model onto a repository.
+
+[[File:images/CDO_ImportModels.png|frame|none|]]
+
+By default, the wizard maps incoming models to paths in the repository according to their paths in the workspace.  This mapping may be customized in the last page.
+
+As a first step, the wizard analyzes the selected models for cross-reference dependencies.  It is highly recommended also to import any models that references the initially selected models.  Otherwise, they will be updated to reference the models in the repository and it may be difficult to edit them when Papyrus is not connected to the repository.
+
+It is also suggested to import models referenced by the initial selection.  However, references from models in a repository to models in the workspace do not present the same kind of problem of availability as the reverse case.
+
+
+= Sharing Models with a Team=
+One purpose of keeping Papyrus models in a CDO model repository is to share them with a team and enjoy the benefits of real-time collaboration that CDO offers.  However, this entails certain consequences that need to be accounted for in the workflow.
+
+==Locking Objects==
+The context menu in both the '''Model Explorer''' view and the diagrams has actions for locking and unlocking objects.  Locking a model element reserves it for the exclusive use of the editor that has it locked.  Other users connected to the same repository cannot edit it.  Locking an element in a diagram locks not only the model element, but also the view of it in the diagram.
+
+An object locked by you shows a key decoration.  To lock an element, use the '''Locks/Conflicts &rarr; Lock''' context menu action:
+
+[[File:images/CDO_Team_locked.png|frame|none|]]
+
+To unlock an object once you have finished editing it and saved the model, use the '''Locks/Conflicts &rarr; Unlock''' context menu action.  Locks are also automatically released when the editor that holds them is closed.
+
+When another user has locked an element, the editor shows a lock decoration:
+
+[[File:images/CDO_Team_remotely_locked.png|frame|none|]]
+
+Note that in this case, the element cannot be edited:  the '''Properties''' view is disabled and the diagram editor does not show the selection handles.
+
+==Handling Conflicts==
+CDO is a real-time collaborative editing platform.  When other users save changes they have made in models that are open in your Papyrus workbench, the repository server pushes those changes into your editors.  You see those changes in real time.  There is no "synchronize" step as with Git or Subversion source control.
+
+Most changes saved by other users will be in different model elements and diagram views than those in which you have unsaved changes.  These do not present a problem.  However, the repository may push changes in objects that you *have* edited and have not yet saved.  Many of these changes, too, are automatically merged by Papyrus:  changes to features of an object that you have not modified and certain changes in multi-valued features can be merged automatically.  Other changes leave the objects that you have edited in a state of conflict.  This is indicated by a decoration in the diagrams and the '''Model Explorer''' view:
+
+[[File:images/CDO_Team_conflict.png|frame|none|]]
+
+Papyrus cannot automatically resolve these conflicts by merging the incoming changes from the repository with the changes made in your editor.  They require manual intervention to resolve.
+
+On an object that shows conflict, invoke the '''Locks/Conflicts &rarr; Resolve Conflicts''' context menu action.  In the current release, the only strategy available is to rollback the editor's unsaved changes, leaving only the changes pushed by the server from other users.  Future releases will add more options, such as an interactive graphical merge.
