The weighting of shapes allows to get the most sensible choice of the library object during the APM process. It assumes that your content positions have sort of "weight marker" assigned and that such weight marker is available in the library objects.

Note: the shapes weighting is optional and disabled by default. See Turning the shapes weighting on and off.

Example: the content positions are Lead, Picture Story, Downpage and Nib, listed in the order of importance.

Let's assume that you consider the Lead as the most important element, to be processed as prioritized. However, if a library object contains not only a Lead element, but also a Picture Story element, it is considered more sensible than the shape that contains only the Lead element. And if a library object contains all four content positions, it is considered the most sensible.

(NOTE: this approach has a hidden flaw, i.e. more content positions are in a library object, given the limited space on a page, the space for each article will be shorter than in case when there would be only one content position in the library object. Therefore, the described approach would give the priority to the short articles, placing first the shapes that require such articles. The importance of an article is however, expressed also by its body length. Therefore, an article with long body is theoretically more important that a short article. At the present time, the shapes weighting is not taking into consideration the article lengths - it is planned to be implemented soon. )

The following table shows the possible values for four previously mentioned content positions, with some intermediate reserved fields for the optional additional content positions:

Assuming that on any page there would be no more than 10 articles,  the weight marker of a library object containing a Lead and a Picture Story element would be:

9600000000

It contains the same number of digits as there are the max number of articles, allowed on page, in this example, ten digits, and the

Some more examples

Lead+Downpage = 9400000000

Lead+Picture Story+2 Nibs = 9611000000

Lead+3 nibs = 9111000000
