Penn Treebank tag set link insufficient

The link "https://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html" provided with name "Penn Treebank tag set" in sections Tagging and Chunking of manual does not list tags used for chunking. A proper link is needed for anybody to develop applications using openNLP. Found some info on missing tags at "https://www.clips.uantwerpen.be/pages/mbsp-tags" but  not sure if the link can be used in the manual.
