Abstract

Claims (74)

1. A computer-implemented method of managing electronic documents comprising the steps of:

providing a first electronic document, the first document including a plurality of first document content elements;

providing a second electronic document, the second document including a plurality of second document content elements;

defining a parent-child relation between the first document and the second document to form a hierarchy of electronic documents that includes the first and second electronic documents;

defining and enforcing an override relation that binds together a selected first document content element and a selected second document content element and,

revising the first electronic document, wherein the revising of the first electronic document carries out a corresponding revision to the second electronic document, the revising step including steps of:

applying any updates to document content elements that are common to the first and second electronic documents, subject to the defined override relation;

determining which of the first document content elements are not present in the second document content elements, and

adding any first document content element that is not present in the second electronic to the second electronic document.

2. The method of claim 1 , wherein the defining step is carried out with the override relation specifying an override type that determines whether the selected second document content element should be removed, replaced by or appended to the selected first document content element.

3. The method of claim 1 , wherein at least one of the plurality of first and second content elements includes or points to at least one of text, an image, HTML content, video content, a Uniform Resource Locator (URL) and computer code.

4. The method of claim 1 , wherein each content element of the plurality of first and second content elements is associated with a unique content element ID and a signature ID, and the selected second document content element, after the enforcing step is carried out, shares a same signature ID as the selected first document content element to which it is bound by the defined override relation.

5.
