The TNA partonomy is made up of 4 chapters, each of which is subdivided into a number of sections, which are further subdivided into subsections. There are 22 sections forming the TNA. Then, we access the partonomic lists with a variable number of indented entities according to the partonomic hierarchy.
The 4 chapters are at level 1 of the hierarchy. The 22 sections are at level 2 and 3. The subsections are at level 4. Any list at a higher level is usually subdivided into a number of sub-lists at the next level. The user can select any level 2, 3 or 4 to view the entities. Level 1 and possibly 2 (depending on the size of the chapter) are reserved for navigation.
Links to Unit Pages and Entity Pages The referenced pages in the lists will be progressively created and uploaded on this website. That's about 50000 pages with the need to perform a number of validations. Sorry for the temporary inconvenience.
