FAMIX: exchange experiences with CDIF and XMI

In the FAMOOS project we have developed a set of tools for reengineering object-oriented legacy systems. These tools are based on the FAMIX meta model and exchange information using CDIF, an industry standard exchange format. For several reasons XMI, an emerging standard for information exchange, has appealed to us to be used as our interchange format. In this paper we discuss why XMI is interesting for us and what, to our current experience, are the advantages and disadvantages of XMI over CDIF.
