Author Permissions

The following flags are available to the author in controlling the modification of the document and its data: (a) document read only; (b) thaw derived document; (c) open document with password; and (d) edit general properties.

Document Read Only

Documents opened with this flag set is not available for modification of its contents. The contents of the document do not include data found in its Property Sheet.

Documents currently opened and modified when this flag is changed is not covered by the restriction. The change in flag takes effect only when the documents are closed and reopened.

Thaw Derived Document

New documents which are created by initially deriving its contents from this document cannot modify any part of the contents copied from this document. Such contents are said to be frozen. It may only be thawed out if this flag is set. Once thawed out, modifications may be allowed again. Freezing of documents is discussed more fully in the appropriate section elsewhere.

Open Document with Password

If the flag is set, the document cannot be opened until the password is given, if any.

Edit General Properties

General properties cannot be modified unless this flag is set.

Source Properties

To determine whether or not the document has been derived from another document, and whether the relationship created by the derivation may be broken are some of the domain of this group.

Document Source of Derivation

This is the filename (without its path) of the document which the current document has been derived from. An independent document does not have an entry for this and the next property.

Source Last Path

This is the path that the source has been located. An independent document leaves this blank.

Synchronization of Source

Contents which may not be modified directly in a derived document may be altered indirectly by modifying its source. Such modifications are not incorporated automatically to all its derived documents. Instead, each derived document is responsible for such synchronization.

Finding Source

The source might have been moved to another location. To be able to perform synchronization, the new location of the source will have to be determined.

Thawing Allowed

A read-only property indicating whether or not the relationship created by the derivation process can be broken. When derived documents break the relationship, it loses the relationship forever, and becomes independent. The same relationship cannot be created either after the creation of an independent document.

Methods of Thawing

There are three ways of thawing: (a) remove source; (b) unfreeze all; and (c) refreeze all.

Remove Source

This method of thawing is the most basic, just removing the source while keeping all currently frozen contents frozen. It may later on be unfrozen and refrozen.

Unfreeze All

This method of thawing removes the source, if still present, then thaws out all frozen contents. Contents may be refrozen and thawed out as many times at will.

Refreeze All

This method of thawing removes the source, if still present, then refreezes all unfrozen contents which may be frozen. Some contents by default or user setting are not affected by this action. Contents may be thawed out and refrozen as many times at will.
