=head1 SYNOPSIS |
| |
|
| |
This file is an interface to the lonc processes of |
| |
the LON-CAPA network as well as set of elaborated functions for handling information |
| |
necessary for navigating through a given cluster of LON-CAPA machines within a |
| |
domain. There are over 40 specialized functions in this module which handle the |
| |
reading and transmission of metadata, user information (ids, names, environments, roles, |
| |
logs), file information (storage, reading, directories, extensions, replication, embedded |
| |
styles and descriptors), educational resources (course descriptions, section names and |
| |
numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to |
| |
and from more descriptive phrases or explanations. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |
