I have an interesting issue regarding changing names for software that I wanted to hear some discussion about. The book in question: Using OpenRefine It's a handbook on using an open source desktop application currently named OpenRefine. However, the software has gone through several name changes. Wikipedia provides a succinct summary: OpenRefine started life as Freebase Gridworks developed by Metaweb and has been available as open source since January, 2010. On 16 July 2010, Google acquired Metaweb, the creators of Freebase, and on 10 November 2010 renamed their Freebase Gridworks software to Google Refine, releasing version 2.0. On 2 October 2012, original author David Huynh announced that Google would soon stop its active support of Google Refine. Since then, the codebase has been in transition to an open source project named OpenRefine. The OpenRefine website itself says: OpenRefine (formerly Google Refine) is a powerful tool for working with messy data: cleaning it; transforming it from one format into another; extending it with web services; and linking it to databases like Freebase. So the question I have is this: Do we have one work here, or multiple works? If just a single work, what is the preferred title for it? The latest name or the earliest? That is: 130 OpenRefine 430 Google refine 430 Freebase gridworks or 130 Freebase gridworks 430 Google refine 430 OpenRefine If we have multiple works, is it a sequential work relationship or some other kind? If sequential, do we have any existing relationship designators that can be used? continuation of (work) The work that is continued by the content of a later work. Apply generally to serials. replacement of (work) An earlier work whose content has been replaced by a later work, usually because the later work contains updated or new information that makes the earlier work obsolete. Apply generally to single-part units, multipart monographs, and integrating resources. preceded by (work) A work that precedes (e.g., is earlier in time or before in a narrative) the succeeding work. For sequentially numbered works with revised content, see J.2.2 (derivative works). If not sequential, is it derivative? I'm curious to think what others think about software titles as works and how to deal with changes in title, particularly in a case where one company buys another and changes the name of the software.
