.. glossary:: :sorted: Pyramid A `web framework <http://pylonsproject.org>`_. Resource An object representing a node in the :term:`resource tree` of your Substance D application. A resource becomes the :term:`context` of a :term:`view` when someone visits a URL in your application. Resource tree A nested set of :term:`folder` objects and other kinds of content objects, each of which is a :term:`resource`. Your content objects are laid out hierarchically in the resource tree as they're added. Folder An resource object which contains other resource objects. See :class:`substanced.folder.Folder`. Content A :term:`resource` which is particularly well-behaved when viewed via the Substance D management interface. SDI An acronym for the "Substance D (Management) Interface". What you see when you visit ``/manage``. Resource factory An object which creates a :term:`resource` when it's called. It's often just a class that implements the resource itself. Content type An :term:`interface` associated with a particular kind of content object. A content type also has metadata like an icon, an add view name, and other things. Management view A :term:`view configuration` that is only invoked when a user visits a URL prepended with the :term:`manage prefix`. Manage prefix The prepended portion of the URL (usually ``/manage``) which signifies that view lookup should be done only amongst the set of views registered as :term:`management view` types. This can be changed by setting the ``substanced.manage_prefix`` key in your ``development.ini`` or ``production.ini`` configuration files. Service A persistent object in the :term:`resource tree` that exposes an API to application developers. For example, the ``objectmap`` service. Deform A form library that draws and validates forms based on :term:`Colander` schemas. See http://docs.pylonsproject.org/projects/deform/en/latest/ for more information. Colander A schema library which can be used used to describe arbitrary data structures. See http://docs.pylonsproject.org/projects/colander/en/latest/ for more information.
