GXL: toward a standard exchange format

This paper describes ongoing work toward the development of a standard software exchange format (SEF), for exchanging information among tools that analyze computer programs. A particular exchange format called GXL (Graph Exchange Language) is proposed. GXL can be viewed as a merger of well known formats (e.g. GraX, PROGRES, RPA, RSF and TA) for exchanging typed, attributed, directed graphs. By using XML as the notation, GXL offers a scalable and adaptable means to facilitate interoperability of reengineering tools.
