While Model-Driven Software Development (MDSD) is a popular trend in the software development area, it still lacks the support of the appropriate tools in many cases. This can be explained by the fact, that many proposed methods are purely theoretical and cannot be simply introduced in industry. In order to make these methods practically usable, it would be necessary to support those with the appropriate CASE tools, which in turn requires the necessity to implement such tools. Since the MDSD support tool has well-known components, its implementation shouldn't be a problem using suitable solutions for each of these components. In this paper authors study the frameworks implemented in Java programming language that can be used for the model editor development.
