Abstract

Programming languages are, at the same time, instruments and communicative artifacts that evolve rapidly through use. In this paper I describe an online computing platform called BioBike. BioBike is a trading zone where biologists and programmers collaborate in the development of an extended vocabulary and functionality for computational genomics. In the course of this work they develop interactional expertise with one another’s domains. The extended BioBike vocabulary operates on two planes: as a working programming language, and as a pidgin in the conversation between the biologists and engineers. The flexibility that permits this community to dynamically extend BioBike’s working vocabulary—to form new pidgins—makes BioBike unique among computational tools, which usually are not themselves adapted through the collaborations that they facilitate. Thus BioBike is itself a crucial feature—which it is tempting to refer to as a participant—in the developing interaction.Keywords: Trading zones; Collaboration; Interactional expertise; Genomics; Computer programming languages; Lisp.
