ETADATA

When a video (.mp4) file is uploaded from a Telepresenter, an associated meta-data file is uploaded as well. This
file, in XML format, contains useful information about the contents and format of the video file just recorded. Items
such as the Title, Presenter, Description, Duration, Aspect Ratio, etc. are contained in this file and these items
form the basis for indexing the file, for creating RSS or other announcements about the file, and for management
of the file through automatic scripts. Details about the contents of this file may be found in the Telepresenter
Reference Manual. Do not delete these files unless it is absolutely certain that they will not be needed.

LAYBACK

Normally, links for playback of archived files will be presented to the user on the organization’s website or in an
associated course management system. The N-Way Server, however, also provides a basic utility program for
displaying and linking to content which can be used if other methods are not available or not needed. This
program is called “nwayfiles” and may be reached at this URL:

http://nway.server.com:8008/cgi-bin/nwayfiles.py

This program, when invoked, searches through all content directories (starting at /usr/local/movies/m3) and
presents a search list to the user to assist in selecting which archived files to display:
