NAME Flickr::Upload::Dopplr - Flickr::Upload subclass to assign location information using Dopplr SYNOPSIS use Flickr::Upload::Dopplr; my %dp_args = ('auth_token' => 'JONES!!!!', 'tagify' => 'delicious'); my %fl_args = ('key' => 'OH HAI', 'secret' => 'OH NOES',, 'dopplr' => \%dp_args); my $uploadr = Flickr::Upload::Dopplr->new(\%fl_args); my $photo_id = $uploadr->upload('photo' => "/path/to/photo", 'auth_token' => 'O RLY'); DESCRIPTION Flickr::Upload subclass to assign location information using Dopplr. Specifically, the package will query Dopplr for the current location of the user associated with *$dopplr_authtoken* and assign the following tags for the name of the city a machinetag representing the Geonames.org ID for that city. If the package is able to query a photo's EXIF data and read the *DateTimeOriginal* field that value will be used to query Dopplr for your location on that day. It will also try to resolve a corresponding Flickr Places ID for the Geonames city ID returned by Dopplr. For example, Geonames ID *5391959* becomes *San Francisco, California, United States* which becomes Flickr Places ID *kH8dLOubBZRvX_YZ*. (Or in machinetag-speak, *places:locality=kH8dLOubBZRvX_YZ*) If, when the photo is uploaded, the Dopplr API thinks that it is a "travel day" another machine tag (dopplr:trip=) will be added containing the numeric identifier for that trip. If an upload is successful, the package will attempt to assign latitude and longitude information for the photo with a Flickr accuracy of 11 (or "city"). ERROR HANDLING Flickr::Upload::Dopplr subclasses Error.pm to catch and throw exceptions. Although this is still a mostly un-Perl-ish way of doing things, it seemed like the most sensible way to handle the variety of error cases. I don't love it but we'll see. This means that the library will throw fatal exceptions and you will need to code around it using either *eval* or - even better - *try* and *catch* blocks. There are four package specific exception handlers : * FUDException An error condition specific to *Flickr::Upload::Dopplr* was triggered. * FlickrUploadException An error condition specific to *Flickr::Upload* was triggered. * FlickrAPIException An error condition specific to calling the Flickr API (read : *Flickr::API*) was triggered. This is the only exception handler that defines its own additional methods. They are : * error_code The numeric error code returned by the Flickr API. * error_message The textual error message returned by the Flickr API. * NetDopplrException An error condition specific to *Net::Dopplr* was triggered. CAVEATS * Asynchronous uploads are not support and will trigger an exception. * At the moment, the package does not check to see whether geo information was already assigned (for example, via GPS EXIF data) nor does it issue and error reporting if there was a problem assigning geo information. PACKAGE METHODS __PACKAGE__->new(\%args) All the same arguments required by the *Flickr::Upload* constructor plus the following : * dopplr A hash reference containing the following keys : * auth_token String. *required* A valid Dopplr API authentication token. * tagify String. An optional flag to format tags for cities, specific to a service. Valid services are : * delicious City names are lower-cased and spaces are removed. * flickr City names are wrapped in double-quotes if they contain spaces. The default value is *flickr* Returns a *Flickr::Upload::Dopplr* object. OBJECT METHODS YOU SHOULD CARE ABOUT $obj->upload(%args) Nothing you wouldn't pass the Flickr::Upload *upload* method. Except the *async* flag which is not honoured yet. I'm working on it. In additional, you may pass an optional *geo* parameter. It must be a hash reference with the following keys : * perms Itself a hash reference containing is_public, is_contact, is_family and is_friend keys and their boolean values to set the geo permissions on your uploaded photo. If this is not defined then your default viewing settings for geo data will be left in place. Returns a photo ID!
