<p class="MsoNormal"><span lang="EN-GB">One of the key capabilities which an OAIS should be able to provide is Representation Information to accompany the Data Object to make an Information Object which can be understood by its Designated Community, however
the OAIS may have more Representation Information, perhaps kept in anticipation of changes in Knowledge Bases. A non-OAIS archive may have some RepInfo so here we focus on OAIS archives but remember that the archive (whether OAIS or not) may return “null”
if it cannot supply what is needed, and this may mean that the Data Object cannot be made to be usable by the requestor.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">For those outside the Designated Community the OAIS can get Representation Information which may be enough for the Information to be enough. Alternatively, it may be necessary to Transform the Data Object in order for
the Information to be usable by someone in this other group of users.<o:p></o:p></span></p>
