Before you Start

Who can use this feature

Users with Any account

Users with Edit access to the project

Included in the Obeo Cloud Platform Modeler

You can adjust various settings of a project from the Project Settings page, accessible using the gears icon in the top-right of the Project Editor:

  1. The Overview tab gives some general information about the project.

  2. From the Teams tab you can give fine-grained access to the project to specific groups of users.

  3. From the Webhooks tab you can configure which webhooks are enabled for this project.

Project Owner and Visibility

The current project owner and visibility are available in the Overview tab of the project settings.

A project is always owned by a single user, initially the one who created the project. Regardless of the other settings, the project owner always has complete admin access to the project and its settings.

If you are the owner of a project or have admin rights on it, you can transfer the ownership to a different user. In the Overview tab of the project settings page:

  1. enter the username (login) of the new owner in the text field.

  2. click on the Change owner button.

The effect is immediate. Note that if the project is private and you do not have explicit access to it as part of a Team (see below), transfering ownership to someone else can lock you out of the project. Use with caution!

A project also has a visibility, which can be either public or private.

  1. If a project is public, all users on the system will be able to view all of its content, but not make any modification (unless explicitly authorized).

  2. If a project is private, by default only the project owner can view it.

To change the visibility of a project after its creation, assuming you have the rights to do it, simply select your choice in the project setting’s overview tab. The effect is immediate.

To give Read-only access to a private project or give collaborators Edit access to a (public or private) project, you can define Teams in the corresponding tab.

Project Teams

Teams let you invite collaborators to access your project. You can control how collaborators interact with your Team using Access level.

Adjust Team Access Level

As the owner of a project, you can update the access level of a team at any time:

  1. Open the Project Settings page.

  2. Click the View all teams link next to the Teams section.

  3. Set the Access level for a team.

There are three to choose from:

  • Read-only: Viewers can only see all the models and representations of the project but can not make any change.

  • Edit: Contributors can see, create and edit all the models and representations of the project.

  • Admins: Administrators can see, create and edit all the models and representations of the project and manage the project owner and teams.

This setting will define what level of access each user or team has within a project. Note that a given user can be part of multiple teams; in that case, his access level is the highest one of all the teams he is part of.

Developer Guide

This sections describes the main APIs that are exposed by the Obeo Cloud Platform Modeler to build custom modelers and extend the platform.

Every instance of the Obeo Cloud Platform Modeler is a custom Spring Boot application built by using reusable frontend and backend components provided by the Open Source Sirius Components project. When running on the entreprise version of the Obeo Cloud Platform Modeler, additional, proprietary components are available to provide more features, but the principles are the same.

The Sirius Web repository provides an example of a complete, ready-to-run studio based on the Open Source components. It can be used as a starting point to create your own modeler.

4. Business Domain Definition

While the architecture of the Obeo Cloud Platform Modeler is not tied to the Eclipse Modeling Framework, EMF models are currently the first supported type of domain models.

If you have an existing EMF metamodel which represents your business domain, to use it in you modeler you need to:

  1. Make sure the JARs for the metamodel itself and its .edit support are in your application’s classpath. Typically this involves publishing the two JARs in a Maven repository and adding their coordinates into your sample application’s POM file. Example in Sirius Web.

  2. Register your metamodel in your application. This is done by creating a Spring @Configuration which provides your meta-model’s EPackage and AdapterFactory as Spring @Beans. Example in Sirius Web.

  3. Provide an implementation of org.eclipse.sirius.web.api.services.IImagePathService which tells Obeo Cloud Platform Modeler in which folders (relative to the root of the JAR) the icons for your metamodel types can be found. Example in Sirius Web.

If you do not yet have an EMF-based domain model, you can use Ecore Tools to design and implement it, and then follow the same steps as above.

5. Sirius Desktop Compatibility

Modelers based on the Obeo Cloud Platform Modeler can reuse Sirius Desktop modeler definition files (.odesign files). Only a subset of the Sirius Desktop features are currently supported, but you can safely use a complete odesign file in the Obeo Cloud Platform Modeler. The features which are not supported at the moment will simply be ignored. Future versions of the Obeo Cloud Platform Modeler will increase the scope of Sirius Desktop features supported. If you rely on specific features from Sirius Desktop, do not hesitate to contact us.

The Obeo Cloud Platform Modeler currently only supports a subset of Sirius diagrams and properties views. Tables, trees, and sequence diagrams are not supported at the moment.

For diagrams, the Obeo Cloud Platform Modeler currently supports the main features of:

  • nodes and containers;

  • relation-based and element-based edges;

  • border nodes;

  • style customizations;

  • creation tools, direct-edit tools, generic tools.

For properties view, the following widgets are supported:

  • text fields and text areas;

  • checkboxes;

  • radio buttons;

  • select/combos;

  • lists (read-only).

To use an existing odesign modeler definition in the Obeo Cloud Platform Modeler:

  1. Make sure the JAR which contains the modeler definition is in your application’s classpath. Typically this involves publishing the .design JAR in a Maven repository and adding its coordinates into your sample application’s POM file. Example in Sirius Web.

  2. In your application, provide a Spring @Configuration which implements org.eclipse.sirius.web.compat.services.api.ISiriusConfiguration and tells the platform the path (inside the JAR) where the .odesign file is available. Example in Sirius Web

6. Project Webhooks

Before you Start

Who can use this feature

Users with Owner access to the server can manage the webhooks

Included in the Obeo Cloud Platform Modeler

Learn the basics of how webhooks work to help you build and set up integrations.

Webhooks allow you to build or set up integrations which subscribe to certain events on the Obeo Cloud Platform Modeler. When one of those events is triggered, we’ll send a HTTP POST payload to the webhook’s configured URL. Webhooks can be used to update a database, update a backup mirror, integrate with another web appllication. You’re only limited by your imagination.

When a project event is triggered, the Obeo Cloud Platform Modeler provides a way to notify an external application. This mechanism is named webhook and works thanks to a REST API.

A webhook must observe the following prerequisites:

  • Expose an HTTP/HTTPS endpoint that implement a GET and POST method

  • The GET method must return a valid the Obeo Cloud Platform Modeler Webhook Manifest

  • The POST method should expect to receive a body with a Webhook Notification

The Obeo Cloud Platform Modeler provides several types of events to listen:

  • SEMANTIC: Triggered when a semantic object or a model is created, updated or deleted.

  • REPRESENTATION: Triggered when a representation is refreshed.

A webhook can listen one or a mix of these event types

6.1. Register a Webhook

When you register a new webhook, the only thing to define is its URL.

To register a new webhook:

  1. Open the Project Settings page.

  2. Click the Webhooks section.

  3. Set the URL.

  4. Click on Add.

6.2. Unregister a Webhook

To unregister a webhook: . Open the Project Settings page. . Click the Webhooks section. . Click on the Remove button.

6.3. Webhook Manifest

A valid webhook manifest:

{
  "manifestVersion": "1.0",
  "name": "Webhook Demo",
  "eventTypes": ["SEMANTIC", "REPRESENTATION"]
}

All fields must be valuated:

  • manifestVersion: The manifest version of the webhook API

The actual and only version of the webhook API is "1.0"

  • name: The webhook name to use in the project webhook admin page

  • eventTypes: The expected webhook event types to listen

6.4. Webhook Notification

The webhook POST endpoint will receive notification messages. You can retrieve the json notification message in the POST body.

A semantic notification example:

{
  "id": "f8b5d193-2ae1-413d-984b-ca3a2fd67cac",
  "projectId": "e8ee9867-61ab-41b3-b67c-ef564dab12b2",

Release Notes

Version 2020.10.0

Initial release!

The Obeo Cloud Platform Modeler is a unique technology to easily develop custom and state-of-the-art modeling tools to be deployed in the Cloud.

OCP Modeler is built as an open-core product relying on Sirius Web. It extends the Open Source Sirius Web with Enterprise features, to deploy on public, private clouds or on premise and includes support and upgrade guarantees.

New

  • Principles you like in Sirius Desktop, available on a modern cloud-based stack:

    • Graphical and Domain-Specific: Create custom graphical modeling workbenches support both your specific visual notation and your own domain concepts.

    • Defined by a Configuration File: Visual editors are declared by a configuration file which is interpreted at runtime, meaning very few lines of code and easy tuning.

    • Deployed on a Web Server: The backend of your modeling tool is deployed on a web server running with state-of-the-art technologies: Spring, React, PostgreSQL, GraphQL.

    • Rendered in a Web Browser: Once deployed on a server, just start using the modeling tool directly from a web browser, without specific installation on user’s desktop.

  • Easily create and deploy studios to the web:

    • Projects Browser: lists all the projects accessible with your account.

    • Project Editor: the main page where you can explore a project, edit a model and get a graphical representation

      • The Project Explorer: navigates through the models of a project,

      • The Details View: presents the properties of the current selected element,

      • The Diagram Editor to manage model elements graphically.

Fixed

  • None yet, this is the first release.

Changed

  • None yet, this is the first release.

Enterprise

  • Users management: Control who can connect, only users authorized by the administrator can access to the hosted projects and their contained models.

login

To share a project with other users, its owner can make it public and/or define access rights. Once connected, any user is able to create a project and share it with other users.

public

  • Teams: Define role-based access control, permissions on a project (read, write, admin) are defined by creating teams. It allows the administrators of a project to manage users depending on roles shared by a set of other users (rather than defining the permissions at the individuals' level).

team

  • Live collaboration: Indicators of Active Users, view in real-time who is working on a diagram. Visual indicators show you in real-time the other users who are currently working on the same diagram as you. Indicators also show you who is on the objects that you are editing and which properties are currently changing.

LiveCollaboration

Developer

  • Webhooks: Webhooks allow you to build or set up integrations which subscribe to certain events on the Obeo Cloud Platform Modeler. When one of those events is triggered, we’ll send a HTTP POST payload to the webhook’s configured URL. Webhooks can be used to update a database, update a backup mirror, integrate with another web application. You’re only limited by your imagination.

Known issues

Here is where you can find a list of issues currently being investigated by our engineering team. This list will be updated regularly, and issues will be added and removed as they are discovered and resolved.

Projects Management

Missing navigation links between some pages

  • Issue description: Some parts of the UI are currently missing navigation links to go back once they are opened. For example, when opening the Project Settings page, there is no explicit link to go back to the project.

  • Workaround: Either use the browser history to go back to the previous page, or go back to the Projects List page (click on the top-left icon) and then navigate to the target page from there.

  • Issue status: Planned.

In some circumstances, models do not appear immediatly inside the model explorer

  • Issue description: Under some circumstances (notably after a period of inactivity on an open browser tab), existing models are not visible inside the model explorer when opening a project, or right after they are created.

  • Workaround: Refresh the browser page (F5) to make the models visible.

  • Issue status: Fix in progress.

The Onboarding area can not be re-opened once a diagram has been opened

  • Issue description: When first opening a project, the center of the page displays an Onboarding UI with easy access to the most common actions to get started. However once you have opened a diagram it is not possible to get back to this UI.

  • Workaround: Go back to the Projects List and re-open the project to see the onboarding area again.

  • Issue status: Planned.

When downloading a full project, the files inside the archive do not have an extension

  • Issue description: When you download the full content of a project, you get a zip archive. The archive contains all the models and representations contained in the project, each in a separate file, but the files do not have an extension. In practice all the files are in JSON.

  • Workaround: if you need to inspect the files' content, rename them with the .json extension before.

  • Issue status: Planned.

Long operations do not provide an indication that they are in progress

  • Issue description: When triggering a long-running operation (e.g. creating or opening a very large diagram or invoking a costly tool), there is no feedback for the user that the operation is in progress. If the operation is running server-side, the client UI can still be reactive, which allows the user to trigger other operations on projet states which will soon be invalid, which can cause unexpected effects.

  • Workaround: None at the moment (keep calm and wait).

  • Issue status: Implementation in progress for some operations; planned for later for others.

Diagram Editor

The current zoom displayed in the combo is not synchronized

  • Issue description: In the top-right corner of a diagram, a combo-box is available to select a specific zoom level. However if you change the zoom level using the mouse wheel, the value displayed in the combo is not updated and thus does not reflect the current level anymore.

  • Workaround: None at the moment.

  • Issue status: Implementation in progress.

A left click on the diagram always opens the palette, even when clicking to drag/scroll

  • Issue description: When you left-click on the diagram, the contextual palette always opens, even if you simply wanted to select an element or scroll/pan inside the diagram, and not invoke a tool.

  • Workaround: You can use the right mouse button to scroll around the diagram, which does not open the palette, and use the left button only to select elements/open the palette.

  • Issue status: Under investigation (the palette should only open on a simple click, not on a click and drag action).

Under Firefox, the contextual palette on diagram does not open at the correct location

  • Issue description: Under Firefox, when you click inside a diagram to select an element, the contextual palette sometimes opens too far from the mouse location (especially when selecting elements inside containers). Note that despite its incorrect location, the palette and its elements still work correctly and apply to the selected element.

  • Workaround: Use a Chrome based browser.

  • Issue status: Planned.

Diagram tabs can not be closed

  • Issue description: When opening a diagram, it creates (or reuses) a tab at the top of the diagram area, but these tabs can not be closed.

  • Workaround: None at the moment, but note that this does not have any impact on memory/performance. Diagrams which are not currently visible in inactive tabs do not take up any resources.

  • Issue status: Implementation of a simple "close" button is in progress, with more complete tab management features in design phase and planned for later.

Direct Edition of edges' labels does not work

  • Issue description: If you select an edge on a diagram and hit F2 (or start typing), a direct edit field opens, but if you try to change the label it has not effect.

  • Workaround: Edit the corresponding model attribute using the properties view of the edge.

  • Issue status: Implementation in progress.

Deletion of edges from the palette does not work

  • Issue description: If you select and edge on a diagram and try to invoke the Delete tool from the palette, nothing happens.

  • Workaround: Edit the corresponding reference in the model using the properties view.

  • Issue status: Implementation in progress.

The palette and modal dialogs sometimes disappear without user intervention

  • Issue description: If you are working on a shared project and open the contextual palette or a dialog, sometimes the palette or dialog disappears without you doing anything. This is due to another user having made a change on the project while the palette/dialog was opened on your side. The remote change triggers an automatic update of your view of the project, which invalidates the palette or dialog currently opened.

  • Workaround: None at the moment.

  • Issue status: We are currently examining which behavior would be the best in such a case before implementing it.

Downloading and re-uploading a model may lose some information

  • Issue description: When downloading a model as a local file (Download context menu item from the explorer) and then re-uploading the same file (Upload Model from the project’s context menu), depending on the underlying metamodel it is possible that some references are lost in the process.

  • Workaround: None at the moment.

  • Issue status: Planned.

Project Explorer

The "New Object" menu entry sometimes open a dialog which does not offer any choice

  • Issue description: In the model explorer, all the model elements offer the "New Object" context menu entry to create sub-elements. However not all object types support sub-elements. For those, the menu entry is currently available anyway, but does not propose any concrete choice. It should simply not be proposed in the context menu in this case.

  • Workaround: None at the moment.

  • Issue status: Fix in progress.

Details view

Multi-valued references can not be edited

  • Issue description: If you select an element which has a many-valued reference to other elements, the properties view displays de list of referenced element, but no edition operations are available.

  • Workaround: None at the moment.

  • Issue status: A more complete list widget, with create/add/remove/reorder operations is planned for future versions.

Non-modifiable properties appear as editable in the properties panel

  • Issue description: Even if you have write access to a project, some elements can have properties which are not editable (for example if they are derived from others). Currently there is no feedback for this: the properties appear editable but trying to change them has no effect.

  • Workaround: None at the moment.

  • Issue status: Implementation in progress (widget of non editable properties will appear disabled).

Newly created elements are not automatically selected

  • Issue description: When creating new elements (either from the explorer or directly from a diagram), the diagram will automatically be updated and display them (if relevant to the current diagram), but they will not be selected.

  • Workaround: None at the moment (except manual selection after the refresh).

  • Issue status: Planned.

When trying to create an edge there is no feedback when the target element is incompatible

  • Issue description: If you select an element on a diagram and then click in the palette on an edge creation tool, you can then point to the target element for the new edge. There is currently no visual feedback if you point towards a target element which is not compatible with the source and/or the type of edge, which can cause confusion as nothing happens when you select the target element.

  • Workaround: None at the moment.

  • Issue status: Under investigation (the mouse cursor should change to indicate the target is invalid).

In the properties view, editing a text field is only taken into account with the 'Return' key

  • Issue description: If you select an element in the explorer or on a diagram, its properties are displayed in the properties view on the right. If you change the value of a text property, the change will only be taken into account reliably when you hit 'Return'. Just selecting another part of the UI may lose the change.

  • Workaround: Always validate your text properties change with 'Return'.

  • Issue status: Fix in progress.
