Nurse rostering represents an interesting timetabling problem which
is well known to be challenging from an optimisation perspective. Academic nurse rostering, however, lacks a generally accepted model, and therefore lacks a generally accepted format for sharing data. This paper presents XESTT, a unified model for expressing nurse rostering instances and solutions, based on the XHSTT high school timetabling model. Instances and solutions from several repositories have been converted to XESTT. Its form makes it likely that future instances could be accommodated easily. The use of XHSTT gives access to some useful existing software, including a web server for evaluating solutions, and a free, open-source solver platform.
