erwin Evolve 2020.2.1 - User Guide

Users, Roles and Access Rights

Users, Roles and Access Rights

In order to view an access controlled Evolve Site, a User must log in with a valid Username and Password (or be given permission through Active Directory or SAML2 group acess). There are three types of User:

•Static Users - who can access a pre-generated static site. (If Static Authentication is turned off, anyone with access to the webserver will be admitted).

•Social Users - who only have read-only access to data, but can use all the Social features of Evolve, so they can Rate objects, set Favorites, collaborate using Comments and Questionnaires, and can Share pages with other Users

•Contributors - who can do all of the above, but can additionally Edit data as well, and can be involved in Workflow tasks.

•Diagrammers - who have the same rights as Contributors, but can additionally edit and create Diagrams using eModeler.

All Evolve Sites can have Static and Social Users, however a special license is required to have Contributors - and the license also controls how many Contributors you can have.

Web Modeler, for example, is a licensed application. Additional licenses are required on a per user basis in order to use Web Modeler on your Evolve Site.

Controlling who can see what?

There are two factors that determine which content a User can see in an Evolve Site:

•Roles - determine which Site pages a User can view

•CW Suite Access Rights - determine which objects a User can see, and whether they can create, read, edit or delete those objects.

Roles

Roles are used to determine which pages within the Site a User is able to view. That means the Menus and links in the interface are updated to remove all links to pages that the Role determines the User should not be able to see.

If a page has no Roles assigned to it, then all users in any Role can view it.

As an Evolve Administrator you can create as many Roles as you like, assign Users to those Roles, and then specify exactly which pages a Role is able to view.

If a User is in more than one Role, Evolve looks at all relevant Roles to see if the User is able to view the page.

Roles are also used with Evolve Workflow to specify who must approve changes made to data by other users.

For details on Roles and assigning Users to Roles, see: Working with Roles.

CW Suite Access Rights

While the type of User you are (Social User or Contributor) specifies what you can do in Evolve, and Roles control which pages you can see, CW Suite Access Rights and Extended Access Controls are used to determine what capabilities a User has with specific objects at a granular level.

CW Suite Access Rights can be used to make a User Read-Only, control which Models they can see, and what they can do with certain types of objects, like ones that are Frozen.

Extended Access Controls can be used to specify whether a User can Create, Read, Update or Delete objects based on either their Object Type or Category.

CW Suite Access Rights and Extended Access Controls are the final level of access control within Evolve. Even though a User might be a Contributor, and they can view a Table listing some Processes, they may not be able to edit all of the Processes listed. They may not even see all the Processes - and another User may see a different list of Processes.

For full details on CW Suite Access Rights and Extended Access Controls, please refer to the CW Suite documentation.

Active Directory or SAML2 Authentication

You can configure an Evolve Dynamic Site to automatically authenticate users based on Active Directory or SAML2 group membership.

Users authenticated in this way only have to browse to the Evolve URL and they are automatically signed in, without having to enter a username and password.

As an Evolve Administrator, you can state that Users in a specific Active Directory group should be Static Users, Social Users, Contributors or Diagrammers and you can assign them to an Evolve Role, and a CW Group.

Running Evolve Designer

Running Evolve Designer

Evolve Designer is the application used to create, configure and manage Evolve Sites.

How to access and run Evolve Designer

For Dynamic Sites, or Static Sites that are directly published to a web server machine running Microsoft Internet Information Services (IIS), Evolve Designer must run on the web server itself.

We recommend that you do the following two steps to access and run Evolve Designer:

1.Create a Desktop shortcut for Evolve Designer.

2.Configure the shortcut to force the application to run with administrator privileges.do you want to do?

Create a Desktop shortcut for Evolve Designer

To create a Desktop Shortcut for Evolve Designer:

          1. Right-click on your Desktop background and select New > Shortcut

The Create Shortcut wizard opens

          2. Click the Browse button to navigate to and select evolveDesigner.exe

The normal installation path is C:\Casewise\evolve\Site\bin\evolveDesigner.exe

          3. Click Next

          4. Enter a name for the shortcut

          5. Click Finish.

The shortcut is created.

Configure Evolve Designer to run with administrator privileges

To configure Evolve Designer to run with administrator privileges:

          1. Right-click the Desktop shortcut and select Properties

          2. Click Advanced

The Advanced Properties dialog opens

          3. Select the Run as administrator check box

          4. Click OK

Now, when you click the Evolve Designer shortcut on your Desktop, the program will run with administrator privileges.

Licensing

Licensing

As of the 2018 release of erwin EA/BP Server, licensing is migrating to the standard erwin Inc. license system. During the migration, there will be a grace period, whereby existing customers can continue to use their existing Casewise licenses. erwin do not intend to force customers onto the new licensing, and will work with them to ensure a successful migration.

The license types available for erwin EA/BP Server include:

Activating your erwin License

The process for activating an erwin EA/BP license is very simple.

          1. Support will provide you with a single license file per Server machine that requires licensing.

For example:

          2. Having installed the software, copy this file to your server's desktop.

          3. Double click on the file. You will be presented with a warning:

          4. Press "Yes" to allow the tool to change the registry.

          5. The software now has the purchased licenses activated on the server. To verify this, load the           License Manager.

Open erwin CW Suite - Start Here...

          6.          Click on License Manager, and login.

          7. License Manager will show the license code, activation count and various other attributes.

Returning your erwin License

If you need to move the license from on server to another, this can be performed up to 3 times, without contacting support.

1.Press "Return" in the "Online" section of the License Manage dialog
This will contact the licensing system, and return the license to the pool

2.Activate the software as usual on your new server.

If you run out of activations, you can have the counter reset, by contacting support.

URLs, File Paths and Directory Structures

URLs, File Paths and Directory Structures

This page explains how the URLs, file paths and directory structures work in Evolve.

Evolve Site URLs

There are three different URLs you can use to access Evolve, depending on how your deployment is configured.

Accessing the main Evolve IIS Site

When you install Evolve and Configure the Server, it creates a top-level Evolve IIS Site.

The Site is used to provide the Evolve login dialog, as well as to show the page displaying the list of Model Sites that are available.

The site can be accessed using the following URL:

http://<server-name>/<evolve-IIS-site-name>/

where <server-name> is the name of your web server machine, and <evolve-IIS-site-name> is the name you specified in the Server Configuration application.

Depending on which authentication method your Evolve server is configured to use, when you access the Evolve IIS Site you log on and are then shown a list of all the Dynamic Model Sites you have access to. You can click any of the Model Site links to visit that Site.

Accessing a Dynamic Site

Dynamic Sites are published at the following URL:

http://<server-name>/<evolve-IIS-site-name>/sites/<site-url-name>/

Accessing a Static Site

Static Sites are published at the following URL:

http://<server-name>/<evolve-IIS-site-name>/statics/<site-url-name>/

File paths and directory structures

This section explains the folder structure used by Evolve on the web server machine. The names used are the default names for a typical configuration.

The Evolve files are typically found at C:\Casewise\Evolve

Within this directory, the following directories exist:

Accessing object pages directly by the URL

There are two ways to access content directly in Evolve using URLs.

The Standard URL

Using the 'Share' button:

Will allow a user to share a page with another user. It is also possible to gain the same behaviour by copying the address bar URL from your browser and sharing this with other users. These URLs are model and site dependent. This means that they will only work for a given site, generated by a given model. This is because the identifier for the object is an ID that is local to the model. This is normal, and in almost all cases, is exactly what is required.

A sample of a Standard URL:

localhost/evolve/sites/voxdnoev/index.html#/cwtype=single&cwview=process&lang=en&cwid=1767

Where: cwid=1767 is the local ID for an object.

The UUID URL [Evolve 2016.1.1 and above]

A UUID based URL differs in the way that it identifies objects in Evolve. A UUID URL is still site dependent, in that the first part of the URL identifies the Evolve web site, however the latter part can be used with any site that supports the given object type, and has an object with the matching UUID. This means that objects which have been copied, or transfered by XML (or other means) from one model to another, will still be considered to be the same object.

A sample of a UUID URL:

localhost/evolve/sites/voxdnoev/index.html#/cwtype=single&cwview=process&lang=en&cwuuid= f0a9ed615e7b11e48273a08869a4da20

Where: f0a9ed615e7b11e48273a08869a4da20 is the UUID of the object.

How does this work?

When you access a URL using the cwuuid, Evolve will do a lookup in the model and redirect the page to the matching cwid.

Why might UUID based URLs be useful?

Take an example where you are running a master model in English, and take copies of this model to translate into French. You want to add the ability to reference the translated object from the English object. However, the IDs of the objects within the French model, may differ from those in the English model. It is therefore not possible to create a simple reference.

In this instance it is possible to use the UUID based URL. You can simply take the site portion of the French URL, and add the Object UUID from the English URL, and you have a new URL that can jump from French to English.

NB: To find the UUID of an object, either display this in your Evolve site design, or if you are developing a custom view, look to the JSON data structure that is returned by the Evolve server.
