Dear Matthew,

the question is more of an OpenACS question than an XOTcl question.

however, some answers:
 - i was the "someone" who wrote a sample script for you.

 - ::xo::cc is an the connection context object created by xotcl-core.
 - The connection context object contains per request information
 - The conneciton context ist used as well by the "view" method of
   XoWiki pages to control, whether or not the output should be
   included in a master adp file (with login etc or not). You will
   not like to have this around e.g.  a json code.

i have to assume, that by "object" you refer to an instance of the
class ::xowiki::Object. If you load the prototype page - as described
in my answer in the openacs forum - then an acs_object is
created in the openacs content repository. The entries in the
OpenACS content repository are referenced by name.
When you call e.g. http://..../xowiki/PAGEAME, an
::xowiki::Object with the name PAGENAME residing
in the content folder for the xowiki-instance will be fetched
from the content repository, on this object, the method view
is called, and the ouput is presented to the user.

 From your other positing in the OpenACS forum i see
that you want to include the page in some other adp page

you can do this
<include src="/packages/xowiki/lib/view" url="@url@" 

The variable "url" should point to the xowiki page to be included (e.g.

PS: it makes sense to concentrate the discussion to one place, e.g. the
OpenACS forums.
