In LEXUS a lexicon consists of a structure and of content. You will always need to define a structure for your lexicon before you can add content. The default structure of a new lexicon is a basic LMF structure. A lexicon consists of two data components: LexiconInformation and LexicalEntry. LexicalEntry in its turn consists of two data components: Form and Sense. Data components are holders for data categories, which are the actual values holders. Compare this to a folder and file system. The data components are the folders and the datacategories are the files, which hold the content.

Its up to you to decide what you would want the structure of your lexicon to be. Group data categories which relate to the form of the lexical entry (like orthography, plural, but even image etc) under Form and group data categories related to meaning under Sense (e.g. gloss, definition). For first time users with LMF we refer to the LMF web site. If you wish LEXUS also allows you to completely ignore the LMF framework. Just leave the Form and Sense component for what they are and buikld your structure directly under LexicalEntry.
