I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">collection of facts</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for data that I've seen before include "Collection of items of information" , "Facts given" , "intelligence" , "Numerical facts" , "Evidence" .)
