In a two-dimensional data set two types of structures could be distinguished: primary (basic) data structures and secondary (meaningful structures of structures) data arrangements. According to the offered definition the descriptions of the discerned structures should be called – Physical and Semantic Information.

Although you are not familiar with the notion of information as a complex two-part entity (Physical and Semantic information subdivisions), you truthfully posit Planckian information as a physical information exemplar similar to other representatives of the class such as Shannon information, Fisher, Kolmogorov, Chaitin, and other. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>In your words: <b>“</b></span><b><span lang=EN-GB style='font-size:12.0pt;font-family:"Times New Roman","serif"'>The Planckian information represents the degree of organization of physical (or nonphysical) systems…”</span></b><span lang=EN-GB style='font-size:12.0pt;font-family:"Times New Roman","serif"'>, <b>“<i>Planckian information</i> is primarily concerned with the <i>amount</i> (and hence the <i>quantitative</i> aspect) of information.</b> <b>There are numerous ways that have been</b> <b>suggested in the literature for <i>quantifying information</i> bedside the well-known Hartley information, Shannon entropy, algorithmic information, etc. “</b> (That is, Planckian information is one of them (one of the physical information manifestations), not a foe, not a competitor, not a foreigner or an outsider).</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>It has to be mentioned that such an approach is not predominant in FIS discussions.
