This is particularly true for any analysis of image information. Concerning the analysis of transcribed text markup is indispensable for converting it into components of a structured data base into which each relevant part of the transcription is to be parsed after the markup has been completed. Those various texts are connected with the appropriate digitized images. Textuality, contextuality and context open up a wider range of opportunities for source-oriented, qualitative and quantitative image research that may use different links of source information in various ways. Often, the interpretation of visual data requires the possibility to refer to parts or parts of parts of an image or a manuscript page corresponding to a part of the image description or the manuscript transcription.
Links become necessary.
Such links are mainly reached by using features of digitized image binding. By delimiting and binding, and that way encoding the relevant segments of the image and linking them to the referring portions of the verbal text, one receives sectors and connections which will be available for any further comparison and analysis. In the course of binding, coordinates are created which become part of the structured text data base in elements directly connected to the parts of text which are corresponding to the image segments. They are of high relevance concerning data exchange. Overlappings are possible and can be dealt with in a kind of dialogue policy.
