Recordings and scans are transcribed into texts. Every scan, recording and text originates with one project, although the texts can be used in more than one project. In this way they represent the parsed and tagged elements that the text consists of. An element can refer to an item in the lexicon. Elements can be defined recursively, if necessary to the phonetic level.
Lexical items can be practically everything, from proper names to words, morphemes and even sounds.
The exact type of lexical item depends upon the tag used. A thesaurus database could be used to dynamically link semantically related items within the lexicon, for a single language, or a range of languages. Tags offer structural information on streams and elements. Tags are unique in value. The purpose of this chapter is to take a small text and see if it fits into the datamodel shown above.
