=head1 NAME
Net::Flickr::Backup - OOP for backing up your Flickr photos locally
=head1 SYNOPSIS
use Net::Flickr::Backup;
use Log::Dispatch::Screen;
my $flickr = Net::Flickr::Backup->new($cfg);
my $feedback = Log::Dispatch::Screen->new('name' => 'info',
'min_level' => 'info');
$flickr->log()->add($feedback);
$flickr->backup();
=head1 DESCRIPTION
OOP for backing up your Flickr photos locally.
=head1 OPTIONS
Options are passed to Net::Flickr::Backup using a Config::Simple object or
a valid Config::Simple config file. Options are grouped by "block".
=head2 flickr
=over 4
=item * B<api_key>
String. I<required>
A valid Flickr API key.
=item * B<api_secret>
String. I<required>
A valid Flickr Auth API secret key.
=item * B<auth_token>
String. I<required>
A valid Flickr Auth API token.
The B<api_handler> defines which XML/XPath handler to use to process API responses.
=over 4
=item * B<LibXML>
Use XML::LibXML.
=item * B<XPath>
Use XML::XPath.
=back
=back
=head2 backup
=over 4
=item * B<photos_root>
String. I<required>
The root folder where you want photographs to be stored. Individual
files are named using the following pattern :
B<photos_root>/B<YYYY>/B<MM>/B<DD>/B<YYYYMMDD>-B<photo_id>-B<clean_title>_B<size>.jpg
Where the various components are :
=over 4
=item * B<YYYYMMDD>
photo[@id=123]/dates/@taken
=item * B<photo_id>
photo/@id
=item * B<clean_title>
photo[@id=123]/title
Unicode characters translated in to ASCII (using Text::Unidecode) and the
entire string is stripped anything that is not an alphanumeric, underbar,
dash or a square bracket.
=item * B<size>
Net::Flickr::Backup will attempt to fetch not only the original file uploaded
to Flickr but also, depending on your config options, the medium and square
versions. Filenames will be modified as follows :
=over 4
=item * B<original>
The original photo you uploaded to the Flickr servers. No extension is
added.
=item * B<medium>
These photos are scaled to 500 pixels at the longest dimension. A B<_m>
extension is added.
=item * B<medium_640>
These photos are scaled to 640 pixels at the longest dimension. A B<_z>
extension is added.
=item * B<square>
These photos are to cropped to 75 x 75 pixels at the center. A B<_s>
extension is added.
=item * B<site_mp4>
The MP4 version of a video uploaded to Flickr. A B<_site> extension is added.
=item * B<video_original>
An original video uploaded to Flickr. No extentsion is added.
=back
=back
=item * B<fetch_original>
Boolean.
Retrieve the "original" version of a photo from the Flickr servers.
Default is true.
=item * B<fetch_video_original>
Boolean.
Retrieve the "original" version of a video from the Flickr servers.
Default is true.
=item * B<fetch_medium>
Boolean.
Retrieve the "medium" version of a photo from the Flickr servers; these photos
have been scaled to 500 pixels at the longest dimension.
Default is false.
=item * B<fetch_medium_640>
Boolean.
Retrieve the "medium" version of a photo from the Flickr servers; these photos
have been scaled to 640 pixels at the longest dimension.
Default is false.
=item * B<fetch_square>
Boolean.
Retrieve the "square" version of a photo from the Flickr servers; these photos
have been cropped to 75 x 75 pixels at the center.
Default is false.
=item * B<fetch_site_mp4>
Boolean.
Retrieve the "site MP4" version of a video from the Flickr servers;
Default is false.
=item * B<scrub_backups>
Boolean.
If true then, for each Flickr photo ID backed up, the library will check
B<backup.photos_root> for images (and metadata files) with a matching ID but
a different name. Matches will be deleted.
=item * B<force>
Boolean.
Force a photograph to be backed up even if it has not changed.
Default is false.
=back
=head2 rdf
=over 4
=item * B<do_dump>
Boolean.
Generate an RDF description for each photograph. Descriptions
are written to disk in separate files.
Default is false.
=item * B<rdfdump_root>
String.
The path where RDF data dumps for a photo should be written. The default
is the same path as B<backup.photos_root>.
File names are generated with the same pattern used to name
photographs.
=item * B<rdfdump_inline>
Boolean.
Set to true if you want the RDF dump for a photo to be stored in the file's
JPEG COM block. RDF data will only be stored (for the time being) in the original
image file and not any of the scaled versions.
This option will only work for JPEG files and is still B<experimental>. It may change
or, you know, not always work. Using Adobe's XMP spec is on the list of things to poke
at so if you've got any suggestions on the subject, they'd be welcome.
Default is false.
=item * B<photos_alias>
String.
If defined this string is applied as regular expression substitution to
B<backup.photos_root>.
Default is to append the B<file:/> URI protocol to a path.
=item * B<query_geonames>
Boolean.
If true and a photo has geodata (latitude, longitude) associated with it, then
the geonames.org database will be queried for a corresponding match. Data will be
added as properties of the photo's geo:Point description. For example :
<geo:Point rdf:about="http://www.flickr.com/photos/35034348999@N01/272880469#location">
<geo:long>-122.025151</geo:long>
<flickr:accuracy>16</flickr:accuracy>
<acl:access>visbility</acl:access>
<geo:lat>37.417839</geo:lat>
<acl:accessor>public</acl:accessor>
<geoname:Feature rdf:resource="http://ws.geonames.org/rdf?geonameId=5409655"/>
</geo:Point>
<geoname:Feature rdf:about="http://ws.geonames.org/rdf?geonameId=5409655">
<geoname:featureCode>PPLX</geoname:featureCode>
<geoname:countryCode>US</geoname:countryCode>
<geoname:regionCode>CA</geoname:regionCode>
<geoname:region>California</geoname:region>
<geoname:city>Santa Clara</geoname:city>
<geoname:gtopo30>2</geoname:gtopo30>
</geoname:Feature>
=back
=head2 iptc
=over 4
=item * B<do_dump>
Boolean.
If true, then a limited set of metadata associated with a photo will be stored
as IPTC information.
A photo's title is stored as the IPTC B<Headline>, description as B<Caption/Abstract>
and tags are stored in one or more B<Keyword> headers. Per the IPTC 7901 spec,
all text is converted to the ISO-8859-1 character encoding.
For example :
exiv2 -pi /home/asc/photos/2006/06/20/20060620-171674319-mie.jpg
Iptc.Application2.RecordVersion Short 1 2
Iptc.Application2.Keywords String 11 cameraphone
Iptc.Application2.Keywords String 15 "san francisco"
Iptc.Application2.Keywords String 5 filtr
Iptc.Application2.Keywords String 3 mie
Iptc.Application2.Keywords String 20 upcoming:event=77752
Iptc.Application2.Headline String 3 Mie
Default is false.
=back
=head2 search
Any valid parameter that can be passed to the I<flickr.photos.search>
method B<except> 'user_id' which is pre-filled with the user_id that
corresponds to the B<flickr.auth_token> token.
=head2 modified_since
String.
This specifies a time-based limiting criteria for fetching photos.
The syntax is B<(n)(modifier)> where B<(n)> is a positive integer and B<(modifier)>
may be one of the following :
=over 4
=item * B<h>
Fetch photos that have been modified in the last B<(n)> hours.
=item * B<d>
Fetch photos that have been modified in the last B<(n)> days.
=item * B<w>
Fetch photos that have been modified in the last B<(n)> weeks.
=item * B<M>
Fetch photos that have been modified in the last B<(n)> months.

This trigger is invoked after the object's B<backup_photo> method is
called.

of the current photo, as returned by the Flickr API, followed by a
boolean indicating whether or not the backup was successful.

Returns true or false, if I<$func> is not a valid code
reference.
