FDOs need to support the abstraction principle, i.e., abstracting away details that are not needed at the basic object management level. At that level there is no need to distinguish among different types such as data, metadata, software, semantic assertions, etc., for data management operations. Since FDOs can include bit-sequences encoding any kind of content they represent the highest possible abstraction level. Of course, abstraction can be viewed at much more general level. For abstraction in computer science we can refer to Wikipedia:  (1) The process of removing or generalizing physical, spatial, or temporal details or attributes in the study of objects or systems to focus attention on details of greater importance; it is similar in nature to the process of generalization; (2) the creation of abstract concept-objects by mirroring common features or attributes of various non-abstract objects or systems of study – the result of the process of abstraction.
