The January issue of the journal
Information and Software Technology publishes a
list of most cited articles in software engineering that were published in the year 2000. The original ATerm article ("Efficient Annotated Terms", M.G.J. van den Brand, H.A. de Jong, P. Klint and P.A. Olivier, Software-Practice and Experience 30 (3):259-291 Mar 2000) appears on the sixth position. A follow-up paper describing applications of ATerms appears in that same journal and can be found at
ATerms for manipulation and exchange of structured data: It's all about sharing.
