The Metis module automates the inclusion of the so called "Metis pixel" (Zählmarke) from the German association VG Wort. The pixel is included as an image that is 1px wide and high and it allows VG Wort to count visits to nodes. Based on that count, VG Wort pays authors royalties obtained through the sale of printers, copiers, and other technical devices that might be used to copy texts.
This module allows reference fields of several types to have their widgets' available options limited by the values of other fields in the current entity.
This module allows the creation of links which set default values to form elements.
For example it is possible to create a link to the add node page pre-compiling the title field. In the same way it is possible to create links to pre-compile body, node references, dates or other CCK fields.
