In the paper we describe the results in the development of the tools for handling lexical resources of Czech and possibly other languages. The tools are based on the client/server DEBII platform, they are language independent and use standard XML formats. In this direction we strive to a standardization of the lexical resources and also their interoperability. The goal is to have a collection of the Web based tools for browsing and editing machine readable dictionaries, semantic networks (WordNets),ontologies and lexical databases in general. In particular, we pay attention to the following tools: DEBDict, DEBTerm, PRALED and Visual Browser.
