Nevow Glossary
==============

Object Traversal
  The process by which a Python object is located to render HTML for a given
  HTTP URL. For example, given the URL http://example.com/foo/bar, Object
  Traversal will begin at the "Root Resource" object by asking it for an object
  which is capable of rendering the page at ('foo', 'bar'). The "Root Resource"
  returns an object and a list of unhandled path segments, and the traversal
  continues across this new Resource object until all path segments have been
  consumed.

Page Rendering
  The process by which a Python object, usually a rend.Page subclass, turns
  itself into HTML. Page Rendering involves locating some page data, loading a
  template document, and applying the template to the data, in the process
  generating HTML.

Deployment Environment
  The environment in which a Nevow application is deployed. Generally involves
  an HTTP server which is configured to route certain (or all) HTTP requests
  through the Nevow Object Traversal and Page Rendering process. Deployment
  environments include CGI, WSGI, and twisted.web.

DOM
  Document Object Model. A tree of objects which represent the structure of an
  XHTML document in memory. Nevow uses a nonstandard DOM named "stan", which is
  made up of simple Python lists, dicts, strings, and nevow.stan.Tag instances.

Flattener
  A Python function which knows how to translate from a rich type to a string
  containing HTML. For example, the integer flattener calls str() on the
  integer. The string flattener escapes characters which are unsafe in HTML,
  such as <, >, and &.

Tag
  A class, defined at nevow.stan.Tag, which holds information about a single
  HTML tag in a DOM. Tag instances have three attributes: tagName, attributes,
  and children. tagName is a string indicating the tag name. attributes is a
  dict indicating the HTML attributes of that node. children is a list
  indicating the child nodes of that node.

Tag Specials
  A Tag attribute which is "special" to nevow. Tag specials include data,
  render, pattern, slot, and macro. Tag Specials will never be output as HTML
  attributes of tags, but will be used by the internal Nevow rendering process
  to influence how the Tag is rendered.
