The Activity Explorer which originated in Capella and was contributed to Amalgam last year provides a nice way for complex modelling workbenches to guide their users and avoid the "blank slate" syndrome when starting with the tool. The objective here is to allow specifiers to configure the Activity Explorer directly from the VSM (with all the nice properties this implies, like high-configurability with expression, dynamic behaviour etc.), and to integrate the resulting explorer/editor nicely in the Sirius usage workflow.
Some pointers: * the source code for the Activity Explorer is available in the Amalgam repo, at https://git.eclipse.org/c/amalgam/org.eclipse.amalgam.git/tree/plugins/org.eclipse.amalgam.explorer.activity.ui * some documentation is available at https://wiki.eclipse.org/File:Activity_Explorer-1.0.0.pdf and https://wiki.eclipse.org/ModelingAmalgam/ActivityExplorer. * UML Designer's usage is implemeted in https://github.com/ObeoNetwork/UML-Designer/tree/master/plugins/org.obeonetwork.dsl.uml2.dashboard. * Capella's own usage can be found at http://git.polarsys.org/c/capella/capella.git/tree/core/plugins/org.polarsys.capella.core.explorer.activity.ui.
FWIW, a quick grep on the current source code of KitAlpha and Capella shows the following classes imported: org.eclipse.amalgam.explorer.activity.ui.ActivityExplorerActivator org.eclipse.amalgam.explorer.activity.ui.IImageKeys org.eclipse.amalgam.explorer.activity.ui.api.editor.ActivityExplorerEditor org.eclipse.amalgam.explorer.activity.ui.api.editor.input.ActivityExplorerEditorInput org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.BasicSessionActivityExplorerPage org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.CommonActivityExplorerPage org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.OverviewActivityExplorerPage org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.helper.SelectionHelper org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.viewers.AbstractActivityExplorerViewer org.eclipse.amalgam.explorer.activity.ui.api.editor.pages.viewers.DiagramViewer org.eclipse.amalgam.explorer.activity.ui.api.editor.predicates.IPredicate org.eclipse.amalgam.explorer.activity.ui.api.hyperlinkadapter.AbstractHyperlinkAdapter org.eclipse.amalgam.explorer.activity.ui.api.hyperlinkadapter.AbstractNewDiagramHyperlinkAdapter org.eclipse.amalgam.explorer.activity.ui.api.hyperlinkadapter.PopupMenuLinkAdapter org.eclipse.amalgam.explorer.activity.ui.api.manager.ActivityExplorerManager org.eclipse.amalgam.explorer.activity.ui.api.preferences.PreferenceConstants This is juste grepping for "import org.eclipse.amalgam.explorer.activity.ui", so there might be others which are referenced indirectly. Anyway, this gives a first very rough idea of the "API surface" that KitAlpha and Capella explictly depend on right now.
Continuing the high-level review of code dependencies, here are all the Java classes which seem to depend on static configuration information defined in the plugin.xml files: % git grep -E 'import org.eclipse.core.runtime.(IConfigurationElement|IContributor|IExecutableExtension|IExtension|IExtensionPoint)' -- '**/*.java' | sort src/org/eclipse/amalgam/explorer/activity/ui/api/editor/activities/ExplorerActivity.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/api/editor/pages/ActivityExplorerPage.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/api/editor/pages/BasicSessionActivityExplorerPage.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/api/editor/pages/CommonActivityExplorerPage.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/api/editor/pages/CommonActivityExplorerPage.java:import org.eclipse.core.runtime.IExecutableExtension; src/org/eclipse/amalgam/explorer/activity/ui/api/editor/sections/ActivityExplorerSection.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/internal/extension/point/manager/ActivityExplorerExtensionManager.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/internal/extension/point/manager/ActivityExplorerExtensionManager.java:import org.eclipse.core.runtime.IContributor; src/org/eclipse/amalgam/explorer/activity/ui/internal/extension/point/manager/ActivityExplorerExtensionManager.java:import org.eclipse.core.runtime.IExecutableExtension; src/org/eclipse/amalgam/explorer/activity/ui/internal/extension/point/manager/ActivityExplorerExtensionManager.java:import org.eclipse.core.runtime.IExtension; src/org/eclipse/amalgam/explorer/activity/ui/internal/extension/point/manager/ActivityExplorerExtensionManager.java:import org.eclipse.core.runtime.IExtensionPoint; src/org/eclipse/amalgam/explorer/activity/ui/internal/preferences/ActivityExplorerManagementPreferencePage.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/internal/preferences/ActivityExplorerSelectionBlock.java:import org.eclipse.core.runtime.IConfigurationElement; src/org/eclipse/amalgam/explorer/activity/ui/internal/preferences/ActivityExplorerSelectionBlock.java:import org.eclipse.core.runtime.IExtension; src/org/eclipse/amalgam/explorer/activity/ui/internal/preferences/ActivityExplorerSelectionBlock.java:import org.eclipse.core.runtime.IExtensionPoint; src/org/eclipse/amalgam/explorer/activity/ui/internal/preferences/DefaultPreferenceInitializer.java:import org.eclipse.core.runtime.IConfigurationElement; Most of these dependencies should probably be removed, or more precisely isolated in a single place as an implementation detail. Given its name, ActivityExplorerExtensionManager sounds like a good candidate. The information it provides should be exposed using an abstract API that can then be implemented in a different way. Note that this change will technically break APIs, as all the page implementation classes actually "implement IExecutableExtension" and read their configuration by a call to IExecutableExtension#setInitializationData(IConfigurationElement, String, Object). A different mechanism will be required to provide pages their configuration data which does not assume that information comes from plugin.xml configuration elements. This only covers (part of) the code dependencies that can be detected easily by grepping the code, but does not cover the fact the the current page implementations probably assume this configuration data, wherever it comes from, can be considered static. If we want the Sirius integration to feel "Sirius-native", page configuration will almost certainly contain dynamic information (e.g. interpreted expressions), and itself be dynamic (e.g. appearing/disappearing when viewpoints are enables/disabled, or in development mode when a VSM is modified by the specifier and then reloaded).

Changing the title to reflect the updated scope. Instead of trying to modify the existing Activity Explorer runtime (which is more complex and risky than initially thought), we will create a new implementation with similar concepts but maybe more oriented towards workflow definition, with: * a way for specifiers to define and organize global "actions" that apply to a session/project, which may depend on the current state. This is similar in scope to the pages/sections/activities supported by the Activity Explorer, but maybe a little more dynamic (at least that's the idea); * at runtime, the presentation of these actions inside the aird editor (as a new page). Instead of reusing the Activity Explorer runtime (which is not a good match), we'll use an embedded browser widget with dynamically rendered HTML/CSS/JS.

Closing for the first version for 6.0.0, which should be considered experimental. We'll try to fix the most glaring bugs for 6.0.1 and provide a more stable a functional version for 6.1.0.
Available in Sirius 6.0.0, see https://wiki.eclipse.org/Sirius/6.0.0 for details
