If "o" is a Zope object "o.getId()" (as a python expression; it
is "o/getId" as path expression) is
its id.

When you call a template, then inside it
"template" refers to the template, i.e. "template.getId()" is
the template's id.

If you call "portal_url", it returns the portal's URL.

You can use this in a TALES "string" expression:

    "string: ${container/portal_url}/news"

Read the Zope Book (2.6 edition) and look into the "Examples"
folder of "Products/PageTemplates".
