 For deep-link access to a specific folder (or resource) in LON-CAPA, mediated by LTI launch from a different system, the signed payload included on launch can include the username of the authenticated user who followed a link in another system.  Whether such a username will be accepted, and a session launched for that username in LON-CAPA, or whether the user will be prompted to log-in to LON-CAPA in order to access the deep-linked resource(s) depends on the ``Use identity'' setting in effect for the current course.  If the domain default is set to ``No'', then a Course Coordinator will not be given the option to set ``Use identity'' when configuring Link Protector(s) in a course, and all users will need to log-in to LON-CAPA to complete the launch process.
 
+\item External Tool definition and configuration in domain and/or course
+
+External Tools can be created in a domain by adding definitions to the ``Provider panel'' in the domain configuration for ``External Tools (LTI)'' available via ``Main Menu'' $>$ ``Set domain configuration''.
+
+The Course/Community default settings in a domain's configuration will determine whether external tools defined in the domain are available by default, for use in each of the available types of course container. A second default setting determines whether, by default, external tool definitions may be created by Course Coordinators in each of the course container types.
+
+\item Create standard LON-CAPA problems within a course/community
+
+The small tabs on the right side of the Course Editor for the Main Content area include an ``Assessment'' tab.  One of the functions which may be available within ``Assessments'' is ``Standard Problem'', which allows creation of a new LON-CAPA problem for incorporation in a course.  Unlike the ``Simple Problem'' also available from the same tab, a ``standard'' problem can feature the full functionality of the LON-CAPA Assessment engine.  The Standard Problem link/icon will be listed if the current user has a current author or co-author role, or if the user has neither, will still be listed if the current course is permitted to access its own Course Authoring Space.
+
+The Course/Community defaults in the domain include checkboxes for each of the different course container types, which when checked set the ability to select ``Course Resource'' as the location for a new standard problem being created. Resources created in that location are not listed when browsing or searching the shared content repository, and may only be imported into the course in which they were created, by using the ``Import from Course Resources'' icon/link.
+
+Neither the ``Import from Course Resources'' icon/link nor the ``Course Resource'' as destination for ``Standard Problem'' will be available if the Course/Community default for the course's/community's container type has been left unchecked, and there is no course-specific override of the domain default.

A ``Standard Problem'' icon/link will be available when the Course Editor's
Assessment tab is the currently selectea tabd, if:

\begin{itemize}

\item The current user has an active Author or co-Author role

or 

\item `In-course Authoring'' is set to be available in the course.

\end{itemize}

To create a new LON-CAPA problem in a specified Authoring Space proceed as follows: 

\begin{enumerate}

\item Select \textbf{Course Editor} on the Inline Menu or 
\includegraphics[width=0.03\paperwidth]{docs}
\textbf{Edit course contents}
within Main Menu. 

\item On the in-line menu of the \textbf{Course Editor} screen, 
click \fbox{Assessment}. Next click on
\includegraphics[width=0.03\paperwidth]{stdprob}
\textbf{Standard Problem}.
\item In the expanded box, select the location where the new file should be stored.

\end{enumerate}

If the Authoring Space's homeserver is hosting the current LON-CAPA session then
the file can be stored. Otherwise, pushing the ``Switch Server'' button will transfer
the session to the homeserver, so a new file can be created and stored.

Once a Authoring Space location is chosen, a directory (and optionally a new
sub-directory) can be selected, and a filename entered.

If the chosen location is the course's own Authoring Space, then a ``placeholder''
for a problem instance in the current folder can (optionally) be added. If added,
the title to display in the course's Contents Listing (and Editor) can be entered.

Choosing Yes for ``Use Template?'' will expand the display to permit 
selection of one of LON-CAPA's standard templates as the initial contents of the 
new file.

If a placeholder was added it will be appended to the existing items in the current 
folder in the Course Editor. The new placeholder item will be
hidden from students until the ``hidden'' checkbox has been unchecked,
and the problem itself will have a status of ``published'',
i.e., the initial version will have been copied from the course's 
``Authoring Space'' to its ``Published Resource Space'',
a default metadata file will have been created (and published) 
including specifying restricting its use to just the current course.

After ``Create Problem'' is pushed the problem will be rendered in Authoring Space,
with button(s) available for launch of all editor(s) supported in the homeserver's domain.

For each type of course container, Course/Community defaults in a domain's configuration determine whether ``Course Resource'' is available as a location for a new standard problem created via the Course Editor. The same setting will also determine whether an ``Import from Course Resources'' icon/link is available, by default, in the Import tab in the Course Editor.

A domain's default availability for each course's ``Course Authoring Space'' may be overridden on a course-by-course basis by checking "Use course-specific setting" in the ``In-course authoring of standard LON-CAPA problems'' accessed via the "View or modify a course or community" item (Main Menu).

External Tools can be created in a domain by adding definitions to the ``Provider panel'' in the domain configuration for ``External Tools (LTI)'' available via ``Main Menu'' $>$ ``Set domain configuration''.

Course/Community defaults in a domain's configuration determine whether external tools defined in the domain are available by default, for use in each type of course container. A second default determines whether external tool definitions may be created by Course Coordinators in each of the container types.

A Domain Coordinator can choose to override the domain defaults on a course-by-course basis by checking ``Use course-specific setting'' in the ``External Tool permissions'' menu, accessed via the ``View or modify a course or community'' item (Main Menu).  When that is done one of the following options can be chosen:

\begin{itemize}

\item External tools defined/configured in either domain or course may be used
\item Only external tools defined in domain may be used
\item Only external tools defined in course may be used
\item Use of external tools not permitted

\end{itemize}
