Centralizing online/offline status - step 1

1 Initial Problem

Currently there is no centralized implementation for handling the offline status in different modules.
With release 5.4 the following object types support offline status and each of them used an own implementation

• Booking Manager
• Chatroom
• Date Collection
• Glossary
• HTML Learning Module
• Course
• Learning Module
• Media Cast
• Poll
• Portfolio Template
• SCORM
• Survey
• Survey Pool
• Test
• Test Pool
• Wiki

2 Conceptual Summary

Methods for retrieving and manipulating the offline status will handled in the object service base classes.
ILIAS objects have to define whether they support online/offline settings in their module.xml

4 Technical Information

The following changes are required for implementing a centralized online/offline setting

4.1 Required Changes for  Repository Objects

• Remove online/offline form elements in settings
• Remove access checks regarding read access depending on offline status
• Refactor methods for offline status handling in object classes
• Remove offline status table columns in object settings
• Remove object specific language variables
• Migration to new of DB strucure
• Remove online/offline handling for copying objects
• Remove object specific ListGUI implmentation for the presentation of the offline status in the Repository, Personal Desktop and the Search
• Remove online/offline handling for import and export

4.2 Required Changes for Services

The following changes in the Service "Object" are required for a centralized offline status handling:

• The online/offline status presentation for repository objects in the Repository,  Personal Desktop and the Search will be handled class.ilObjectListGUI
• Access checks ("Visisble" is granted only if the object is online or the user has "Write" permission) will be handled in class ilAccessHandler
• The offline status will be kept after copying an object. The offline status of the top copied container will be set to "Offline".
• ilObjectGUI will provide methods for the handling of the offline status in settings forms.
• new methods in ilObjectDefinition for querying wether an object type support online/offline status

Services/Search:

The Lucene-Search needs to support the new offline status handling.

7 Discussion

JourFixe, ILIAS [jourfixe], 02 JUL 2018 : We highly appreciate this suggestion and schedule it for 5.4. Please provide some more information about the technical concept to give a better impression of possible dependencies, esp. for objects that do not support online/offline yet.

8 Implementation

No changes in existing views. Centralized online/offline status is supported for 5.4 by the following object types:

1. Course
2. ILIAS Learning Module
3. HTML Learning Module
4. SCORM Learning Module
5. Survey
6. Test
