Abstract

The main subject of this article is the problem of the filing of textual data in archaeology in order that they can be analysed and processed automatically. This problem is closely associated to another topic, that of text encoding. An electronic text may contain more than one markup level. The first one is the character encoding, usually the ASCII - 7 bit set, that offers 127 bit combination to represent letters, digits and a few other signs. The ASCII code has the advantage of being a standard valid for every operating system. It is therefore suggested, to encode other signs not included in the ASCII set, the use of a combination of the 127 available characters rather than a combination of 8 bit (256 possible combinations), because the number codes greater than 127 are used for different signs on different systems. A document file may contain another markup that encodes format parameters. To transform a simple document into a “database” where information can be searched and retrieved, the conceptual components must be encoded. The Standard Generalized Markup Language appears to be a good tool to produce files that are software and hardware independent, easy to be managed and ready to be automatically analysed by a software in order to retrieve pieces of information.
