lonpublisher - LON-CAPA publishing handler |
|
|
|
=head1 Synopsis |
|
|
|
lonpublisher takes the proper steps to add resources to the LON-CAPA |
|
digital library. This includes updating the metadata table in the |
|
LON-CAPA database. |
|
|
|
=head1 Description |
|
|
|
lonpublisher is many things to many people. |
|
To all people it is woefully documented. |
|
This documentation conforms to this standard. |
|
|
|
This module publishes a file. This involves gathering metadata, |
|
versioning the file, copying file from construction space to |
|
publication space, and copying metadata from construction space |
|
to publication space. |

=head1 INTRODUCTION |
|
|
|
This module publishes a file. This involves gathering metadata, |
|
versioning the file, copying file from construction space to |
|
publication space, and copying metadata from construction space |
|
to publication space. |
|
|
|
This is part of the LearningOnline Network with CAPA project |
|
described at http://www.lon-capa.org. |
