Call for Papers

Goals and scopes The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. The topics of your paper can be on all aspect of Smalltalk, theoretical as well as practical. Participants are invited to submit research articles or industrial papers. This year we want to open two different tracks: one research track and one industrial track with less scientific constraints.

We expect papers of three kinds:

  • Short position papers describing emerging ideas
  • Long research papers with deeper description of experiments and of research results.
  • Industrial papers with presentation of real and innovative Smalltalk applications; this kind of paper should enlighten why Smalltalk is really appropriate for your application.

We will not enforce any length restriction.
