They can +copy resources into the resource area through the publication step, +and move them back through a recover step. Authors do not have direct +write-access to their resource space. + +During the publication step, several events will be +triggered. Metadata is gathered, where a wizard manages default +entries on a hierarchical per-directory base: The wizard imports the +metadata (including access privileges and royalty information) from +the most recent published resource in the current directory, and if +that is not available, from the next directory above, etc. The Network +keeps all previous versions of a resource and makes them available by +an explicit version number, which is inserted between the file name +and extension, for example C, while the most recent +version does not carry a version number (C). Servers +subscribing to a changed resource are notified that a new version is +available. + +=head1 DESCRIPTION + +B takes the proper steps to add resources to the LON-CAPA +digital library. This includes updating the metadata table in the +LON-CAPA database. + +B is many things to many people. + +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. + +=head2 SUBROUTINES + +Many of the undocumented subroutines implement various magical +parsing shortcuts. + +=over 4 + +=cut + +###################################################################### +###################################################################### + package Apache::lonpublisher; +# ------------------------------------------------- modules used by this module use strict; use Apache::File; use File::Copy; use Apache::Constants qw(:common :http :methods); -use HTML::TokeParser; +use HTML::LCParser; use Apache::lonxml; -use Apache::lonhomework; use Apache::loncacc; use DBI; +use Apache::lonnet; +use Apache::loncommon(); +use Apache::lonmysql; +use Apache::lonlocal; +use Apache::loncfile; +use LONCAPA::lonmetadata; +use Apache::lonmsg; +use vars qw(%metadatafields %metadatakeys); +use LONCAPA qw(:DEFAULT :match); + my %addid; my %nokey; -my %language; -my %cprtag; - -my %metadatafields; -my %metadatakeys; my $docroot; my $cuname; my $cudom; -# ----------------------------------------------- Evaluate string with metadata +my $registered_cleanup; +my $modified_urls; + +my $lock; + +=pod + +=item B + +Evaluates a string that contains metadata.
