Groups criteria related to the appearance of the digital object. Groups criteria related to the page information of the digital image The width of the digital object measured in millimeters. The height of the digital object measured in millimeters. The number of pages in the text document. How similar the layout of the text-document is in relation to the original document. How similar are the margins of the text-document is in relation to the original document. The size of the left margin of the document in relation to the margin of the original document. The size of the right margin of the document in relation to the margin of the original document. The size of the top margin of the document in relation to the margin of the original document. The size of the bottom margin of the document in relation to the margin of the original document. Gathers information about the style of the text document. The background color of the document. This criterion assembles information about the fonts that are used within the document to see if any font information is missing. The size of the font used in the text-document. Font size changes very often so some special processing will have to be done in order to compare font sizes from source and target documents.. Comprises criteria that are related to the intellectual content carried within the digital object. Comprises criteria related to the completeness of the content that constitute the digital object. How well text characters are respectfull to the original document. In cases of multiple page documents, the comparison is performed by page and an overall similarity value is calculated by averaging the whole page set results. The number of pages that constitute the text document. The number of characters of the text document. The number of images embedded in the text document. Comprises information that describes the context that surrounds the object, usually resolved by resorting to metadata. Some text document formats carry embedded metadata. This criterion aims at measuring how much of that metadata was preserved.
