<p class="MsoNormal"><span lang="EN-US">Once again, in the translation work of the OAIS, we have some questions. It is about the definition of the
<b>Reversible Transformation</b> (A Transformation in which the new representation defines a set (or a subset) of resulting entities that are equivalent to the resulting entities defined by the original representation. This means that there is a one-to-one
mapping back to the original representation and its set of base entities.).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">What is meant by “resulting entities” and “base entities” ? Is the one-to-one mapping between the original representation and its base entities or between the new and the original representation base entities ?<o:p></o:p></span></p>
