Bob, Traversal (and acquisition) is (and are) standard Zope 2 terminology. They are described, among other places, on page 226 of the Zope Book: http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/ZopeBook-2_6.pdf Here's an illustrated version of the same explanation: http://plope.com/Books/2_7Edition/BasicScripting.stx#2-6 Zope picked this up from some storied academic paper somewhere I've since misplaced. Several other Python frameworks subsequently picked it up. Here's a paper from the 1996 Python Workshop 5 described how traveral was implemented in what was then called the Python Object Publisher, commissioned by what was then called the Python Software Activity (PSA) which later became the PSF, code-named "Bobo," and later known as the Zope Object Publisher: http://www.python.org/workshops/1996-11/papers/PythonObjectPublisher.html And thus is how all your bobobase came to belong to us. -- Sincerely, Chris Calloway http://www.secoora.org office: 332 Chapman Hall phone: (919) 599-3530 mail: Campus Box #3300, UNC-CH, Chapel Hill, NC 27599 _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
