This is the META section of LEHOism. It contains all the metadata for all the other parts, which means it’s the home of the taxonomies used to classify other content (categories, subjects, series, tags, etc.) and an encyclopedia of entries connected to the taxons, explaining them in more detail. So the taxons classify the content and the encyclopedia entries contain the description of the taxons (and the content of the entries can also be classified with the taxonomies, making for a nice circular meta-meta-meta-meta-…-meta-structure).
