18 WEBDAV ACCESS TO AUTHORING SPACE
At the end of every bridge task there will be a box to submit ﬁles in the portfolio for
grading. When the student click on the link ”select portfolio ﬁles”, a new window is opened
showing the content of the student’s portfolio. The student can create directories in the
portfolio and upload ﬁles using the upload ﬁle buttons.
Once the ﬁles that are needed are uploaded, the student select (by checking the checkbox
next to the ﬁlenames) of all ﬁles that he needs to submit to the instructor. Once all ﬁles
needed are checked oﬀ, the student needs to press the ”select checked ﬁles and close window”
By pressing the close window button, the student’s portfolio window should close, and
the student should see his or her Bridge Task Page. The text ﬁeld in the upload ﬁles into
portfolio should contain the list of names. The student must then press ’submit answer’ to
submit the answer to be graded.
If the student needs to resubmit the ﬁle, the student must repeat the process and check
oﬀ all the ﬁles (not only new ﬁles) that needs to be submitted. Once a ﬁle is submitted, the
student may not overwrite or delete the ﬁles.
18 WebDAV access to Authoring Space
If your domain has Apache with SSL running on the LON-CAPA server where you access
your Authoring Space (i.e., URLs begin https://) and your Domain Coordinator has enabled
webDAV access for users with author or co-author roles, then you will be able to connect to
an Authoring Space using webDAV.
A webDAV connection allows you to mount the Authoring Space directory tree as an
external volume. You can then use your own laptop/desktop computer’s ﬁle management
tools and applications to copy, move, edit and delete ﬁles (including dragging and dropping
The requirement to obsolete published ﬁles before moving or deleting them, which ap-
plies to the regular web browser-based management of Authoring Space, also applies in
the webDAV environment. Moving and deleting directories in the webDAV environment is
prohibited if the directory, or any (nested) subdirectory contains a non-obsolete published
Given the ability to easily delete unpublished content in webDAV (without a mechanism
to reverse the deletion), it is important that you are especially careful when working in the
webDAV environment with this type of content.
When you display the contents of a directory in Authoring Space using webDAV you may
see additional ﬁles, with extensions .log, .save, .bak etc. for each LON-CAPA .problem ﬁle.
You can view the contents of these ﬁles but you will not be able to modify or delete them.
These ﬁles are created by LON-CAPA when using the web GUI. For example, a .log ﬁle,
which records publication history, is updated whenever you use “Publish” to copy a ﬁle from
Authoring Space to Resource Space, and .bak ﬁles enable use of the LON-CAPA “Undo”
button in regular web browser-based editing in Authoring Space.
