CCOW Web Context Participant Responsibilities

Locating the Context Management Registry:

The ContextManagementRegistry interface contains the Locate method. Use the method to locate CCOW components.

For example, to locate the context manager component:
```
var registryData = contextManagementRegistry.locate("CCOW.ContextManager", "1.5", null, clientUrl);
```
This method returns LocateData, which contains the following properties:
- componentUrl (Context Manager URL)
- componentParameters
- site (Domain Name)
Activating\Creating a Context Session:

The ContextSession interface supports the following operations:
1. Activating a Context Session
  
  Activates a context manager so that it represents the active session for a point-of-use device.
2. Creating a Context Session
  
  Instructs the context manager to create a new context manager.
  
  Note: A new session deactivates the current session, allowing users to share the same session.
Joining a Context Session:

To join a common context session, create a Context Manager object, and call the JoinCommonContext method.

Calling JoinCommonContext returns a participant coupon, which is an integer number assigned by the context manager to the application when the application joins a common context session. This coupon is subsequently used by the application to identify itself when it calls a context manager method that requires application identification.

Note: Setting survey to true when joining the common context means the application will participate in context change surveys. If survey is false, the application will only be informed when a context change has been accepted.
Suspending\Resuming a Context Participant:

To suspend an active participation in a common context session while remaining registered as a participant, call the ContextManager.SuspendParticipation

To resume a suspended participation in a common context session, call the ContextManager.ResumeParticipation method.
Leaving the Context Session:

To disconnect the application from the context session, call the ContextManager.LeaveCommonContext method.

Notes:
- To Log off an application: To leave the common context session call the ContextManager.LeaveCommonContext method.
- To Log off all applications (only valid if the signon was performed with SSO enabled): To log off all of the applications that signed onto the common context with SSO enabled, set a logon subject item in the common context with an empty value.
Getting/Setting the Context Change:

The ContextData class is used by applications to get/set the data items that comprise the common context.

The ContextData class contains the following methods:
1. GetItemNames: Gets the names of common subject context items in the context.
2. GetItemValues: Gets the value of one or more common subject context items.
3. SetItemValues: Sets the value of one or more common subject context items.
