Using a database with type entries that are linked to token tags in transcripts has the advantage that consistency in lemmatising is not depending on ID-glosses. In iLex types are organised in different levels. The type hierarchy allows for analysing form, iconic value, and conventionalised meanings of a sign (sub-types). Tokens can be linked either to types or sub-types. We expanded this structure for modelling sign inflection and modification as well as phonological variation. Differences between token and type form are grouped by features, called qualifiers, and specified by feature values (vocabularies). Built-in qualifiers allow for spotting the form difference when lemmatising. This facilitates lemma revision and helps to get a clear picture of how inflection, modification, or phonological variation is distributed among lexical signs. This is also a strong indicator for further POS tagging. In the long term this approach will extend the lexical database from citation-form closer to full-form. The paper will explain the type hierarchy and introduce the qualifiers used up-to-date. Further on the handling and how the data are displayed will be illustrated. As we report work in progress in the context of the DGS corpus project, the modelling is far from complete.
