Knowledge Management and Collaboration Archiving Object

The Knowledge Management and Collaboration (KMC) archiving object is a central concept in KMC data archiving. The KMC archiving object specifies which data is archived and how. It describes which resources must be handled together as a single compound resource, thus facilitating the archiving of Collaboration Rooms and other business objects that are constructed from more than one resource.

The KMC archiving object consists of one main KM resource, but may also contain additional resources associated to the main one, which might reside both in and outside KM (for example, associated discussion objects). It defines the namespace structure of the resources in the archive. The KMC archiving object is also responsible for the proper deletion of the resources once the archiving has been completed successfully.

Depending on the contained resources, the KMC archiving concept differentiates between the following provided out-of-the box object types:

Type	Content	Archiving Object Owner
KM resource	Contains the KM resource, including its properties and versions. You can optionally configure the default resource archiving object and activate the archiving of data stored by the following collaboration services: Feedback service Review service Rating service Personal notes service Discussion service For more information about the collaboration services, see: Collaboration Services . For more information about configuring the default resource archiving object, see Configuring the Default KM Resource Archiving Object .	The user who created the resource In the standard configuration, the archiving object owner of the KM resource is determined by the `Created By` resource property. You can optionally change the default configuration and specify another object owner. For more information, see Configuring the Default Resource Archiving Object
Folder	Contains the entire subtree of the folder. Note Folders themselves are not subject to the approval process.	Not relevant
Collaboration Room	Contains the KM resources and custom extensions relevant for the room. Therefore, the following Collaboration Room elements are subject to the archiving: Metadata such as room name Documents and external links Discussions Meeting material Announcements Member list The IDs and display names of room members are archived as plain text and serve only for reference purposes. Rooms are archived as a whole, room elements such as Discussions cannot be archived separately. Note The archiving of Collaboration Room-specific Portal Content Directory (PCD) content, such as iViews and roles, is not supported.	Room owner Note The archiving object owner of the Collaboration Room archiving object is configured by default. You cannot change the default configuration.

Type

Content

Archiving Object Owner

KM resource

Contains the KM resource, including its properties and versions.

You can optionally configure the default resource archiving object and activate the archiving of data stored by the following collaboration services:

Feedback service
Review service
Rating service
Personal notes service
Discussion service

For more information about the collaboration services, see: Collaboration Services .

For more information about configuring the default resource archiving object, see Configuring the Default KM Resource Archiving Object .

The user who created the resource

In the standard configuration, the archiving object owner of the KM resource is determined by the Created By resource property.

You can optionally change the default configuration and specify another object owner. For more information, see Configuring the Default Resource Archiving Object

Folder

Contains the entire subtree of the folder.

Note

Folders themselves are not subject to the approval process.

Not relevant

Collaboration Room

Contains the KM resources and custom extensions relevant for the room. Therefore, the following Collaboration Room elements are subject to the archiving:

Metadata such as room name
Documents and external links
Discussions
Meeting material
Announcements
Member list

The IDs and display names of room members are archived as plain text and serve only for reference purposes.

Rooms are archived as a whole, room elements such as Discussions cannot be archived separately.

Note

The archiving of Collaboration Room-specific Portal Content Directory (PCD) content, such as iViews and roles, is not supported.

Room owner

Note

The archiving object owner of the Collaboration Room archiving object is configured by default. You cannot change the default configuration.

Note

External links are subject to the archiving process and are archived together with the plain resources. Archiving of internal links is not supported.

The archiving object owner determines the user who receives the notifications and the archiving approval e-mails.

KMC archiving objects of type folder serve as a container for the residing KM resources. When the archiving takes place, the system archives and removes only the contained KM resources in status Marked for archiving . Folders themselves are not archived. After the successful archiving of all contained KM resources, archiving objects of type folder are also removed.

You can extend the list of archiving object types by defining your own archiving object types and implementing the relevant functionality.

Archiving Repository Manager

In the standard delivery, you can choose between storing the archived content on a remote WebDav-compliant server or in a file system. For this purpose, SAP offers two out-of-the-box implementations of the Archiving Repository Manager API:

Archiving WebDAV Repository Manager
Archiving File System Repository Manager

Content administrators and super administrators have read access to the archived content via search or navigation. The representation of the archived content in the archiving repository is as follows:

KM resources, resource properties, and versions are rendered as in the regular KM repositories.
Associated metadata coming from SAP KM applications such as feedback and review are available as plain text only.
Custom unstructured data defined by non-SAP applications are only available for download and can be displayed in the custom application-specific user interface.

Versioning

The system archives all versions of the versioned resources into the ~system~/versions folder of the archiving repository.

Security Manager

SAP offers a separate security manager which controls access to the content in the archiving repository. According to the security model defined by the archiving security manager, super administrators and content administrators have read-only access to the content stored in the archiving repository.

If your archiving scenario requires it, you can change the default configuration of the archiving security manager and provide other users with read-only access to the archiving repository. For more information, see Security Managers .

If you do not want to use the security model provided by SAP, you can implement your own security manager and specify it in the configuration of the archiving repository. For more information, see Configuring the Archiving Landscape .

Caching

The KMC data archiving solution uses the centralized cache management infrastructure provided by the Cache Management Library (CML). For more information, see Cache Management System .

The following table lists the cache regions in the CML used by the KMC data archiving:

Cache Region Description	Cache Region Content
KCF Cache Region For Archiving Object Read Only Info	Read-only status of the KM resources defined by their archiving status. For example, resources that are marked for archiving are in read-only status and cannot be changed.
KCF Cache Region For Archiving Object	Archiving object metadata
KCF Cache Region For Archiving RM Resource	System information - the back-end collection that contains the archived resource
KCF Cache Region For Archiving RM System Info	System information - metadata of the archived resource
KCF Cache Region For Archiving RM Content	System information - content of the archived resource
KCF Cache Region For Archiving RM Children	System information - children of a collection in the archiving repository manager (not the archived collection itself)
KCF Cache Region For Archiving RM Revision Labels	System information - revision labels of the archived versioned resources
KCF Cache Region For Last Access Service	Last access service information - the time when the resource was last accessed

You can view monitoring information about the performance and content of the archiving CML caches in SAP Management Console (SAP MC). For more information, see: SAP Management Console .

In addition to the CML caches, the archiving WebDAV repository manager uses a memory cache for the resource properties.
