SUMMARY:Why We Should Discuss the Identity of Software Products - Jeroen d

DESCRIPTION:Reasoned discourse about software requires that identity condi
 tions of a software product preserve its identity over updates. Despite it
 s failure to produce such identity conditions\, the view that they can be 
 formulated in terms of algorithms or code is nevertheless believed to be o
 n the right track. In this talk\, I shall argue to the contrary\, as the r
 esultant identity conditions cannot be evaluated consistently by independe
 nt parties. Instead\, approaching the problem from a user’s perspective\
 , I arrive at a necessary condition for the identity of software products.
  This condition induces what I call use-plan-compatible equivalence classe
 s. I show how their associated identity conditions both preserve identity 
 over updates and can be consistently and independently evaluated. Still\, 
 not based on a sufficient condition\, the concept of a use-plan-compatible
  equivalence class is arguably too broad. Thus\, the results call for furt
 her discussion of how to delimit more accurately those objects that should
  fall under the concept of a software product.
