Having clarified the purpose of the survey, the first problem to be solved consists in the acquisition and archiving of the information essential to the study of the object. It should not be forgotten that this is not an "egoistic" operation, but it itself must allow the survey user to know the way followed by the detector to reach certain conclusions (in addition, of course, to the provision of the use of the same information). for other findings).
  Undoubtedly it is desirable to fill in appropriate forms (bibliographic, archival, iconographic, urban planning, etc.), provided that they are easily consulted and that their own research is possible with a key word of simple intuition. For the drafting and updating of these forms, simple languages ​​such as "HTML" or "JavaScript" could be used, but it is preferable to create a database with existing programs on the market (for example FileMaker Pro) which, by checking the HTML language , allow you to search and update the same database via the network.    Taking as reference the Mother Church of Cisternino (BR) and examining the historical investigation made by the student, we immediately notice the difficulties encountered by the author for the illustration, despite the interactivity of the text and images. Starting from the need to identify the monument, the fear of not being able to make all the information collected and, therefore, being able to communicate it, appears evident in the author. The page relating to the history of the monument denotes the desire to communicate as much as possible, but at the same time the precautions not to bore the visitor. On the other hand, the use of the Java applet to browse the pages of the historical photo album is a valid method as a guide, but it can be hardly accepted by those who intend to move around the site according to a specific itinerary.
