The development of an information system requires its conceptual schema to be of high quality. Classically, this quality comprises properties such as syntactic and semantic correctness, relevance, and completeness, but many other quality properties have been proposed in the literature. In this demonstration we integrate some published quality properties in Eclipse by extending the core functionalities of MDT. These properties include syntactic issues, naming guidelines, and best practices. A quality property is defined using OCL and is specified in an XML file. The set of quality properties included in our tool is available on an online public catalog that can be extended to include new quality properties. We use XSLT to present this catalog in a friendly manner to users that access it using a web browser.
