Shelf
nsdef:shelfshelf — The Thinker's Shelf reading-programme namespace: the vocabulary a read work is opened with — the source decomposition (book/edition/page/section/passage/bibliographical entry/person/work/place/language/printer/historical reference), the four strata (original/structural/analytical/commentary), the four interpretation levels (SOURCE/DERIVED/INTERPRETIVE/SPECULATIVE), the society roles (Reader/Listener/Commentator), the reading-cycle steps, and the relations the semantic bridge runs on. BOOK OPENETH BOOK: a book is opened, never summarised.
