NAME
Biblio::Citation::Parser::Citebase - Citebase's citation parsing module DESCRIPTION
This module is an updated (and hopefully improved) version of Zhuoan Jiao's citation-parsing modules. SYNOPSIS
use Biblio::Citation::Parser::Citebase; $parser = new Biblio::Citation::Parser::Citebase([$source_identifier]); $metadata = $parser->parse($citation); print "Author: ", $metadata->{aufirst}, " ", $metadata->{aulast}, " "; $p = new Biblio::Citation::Parser::Citebase([$citation],[$source_identifier]); Create a new citation parser, optionally parsing $citation with $source_identifier. If a citation is given the return blessed hash will contain the structured data. $md = $p->parse($citation, [$source_identifier]); Parses a string, $citation, and returns a blessed hash of the structured data. perl v5.10.1 2009-11-15 Biblio::Citation::Parser::Citebase(3pm)

NAME
Bio::Biblio::IO - Handling the bibliographic references SYNOPSIS
use Bio::Biblio::IO; # getting citations from a file $in = Bio::Biblio::IO->new ('-file' => 'myfile.xml' , '-format' => 'medlinexml'); # --- OR --- # getting citations from a string $in = Bio::Biblio::IO->new ('-data' => '<MedlineCitation>...</MedlineCitation>' , '-format' => 'medlinexml'); #--- OR --- # getting citations from a string if IO::String is installed use IO::String; $in = Bio::Biblio::IO->new ('-fh' => IO::String->new ($citation), '-format' => 'medlinexml'); $in = Bio::Biblio::IO->new(-fh => $io_handle , '-format' => 'medlinexml'); #--- OR --- # getting citations from any IO handler $in = Bio::Biblio::IO->new('-fh' => $io_handle , '-format' => 'medlinexml'); # now, having $in, we can read all citations while ( my $citation = $in->next_bibref() ) { &do_something_with_citation ($citation); } #--- OR --- # again reading all citation but now a callback defined in your # code is used (note that the reading starts already when new() # is called) $io = Bio::Biblio::IO->new('-format' => 'medlinexml', '-file' => $testfile, '-callback' => &callback); sub callback { my $citation = shift; print $citation->{'_identifier'} . " "; } #Now, to actually get a citation in an XML format, #use I<Bio::Biblio> module which returns an XML string: use Bio::Biblio; use Bio::Biblio::IO; my $xml = Bio::Biblio->new->get_by_id ('12368254'); my $reader = Bio::Biblio::IO->new ('-data' => $xml, '-format' => 'medlinexml'); while (my $citation = $reader->next_bibref()) { #... do something here with $citation } #And, finally, the resulting citation can be received in different #output formats: $io = Bio::Biblio::IO->new('-format' => 'medlinexml', '-result' => 'raw'); #--- OR --- $io = Bio::Biblio::IO->new('-format' => 'medlinexml', '-result' => 'medline2ref'); #--- OR --- $io = Bio::Biblio::IO->new('-format' => 'pubmedxml', '-result' => 'pubmed2ref'); DESCRIPTION
Bio::Biblio::IO is a handler module for accessing bibliographic citations. The citations can be in different formats - assuming that there is a corresponding module knowing that format in Bio::Biblio::IO directory (e.g. Bio::Biblio::IO::medlinexml). The format (and the module name) is given by the argument -format. Once an instance of "Bio::Biblio::IO" class is available, the citations can be read by calling repeatedly method next_bibref: while (my $citation = $reader->next_bibref()) { ... do something here with $citation } However, this may imply that all citations were already read into the memory. If you expect a huge amount of citations to be read, you may choose a callback option. Your subroutine is specified in the "new()" method and is called everytime a new citation is available (see an example above in SYNOPSIS). The citations returned by next_bibref or given to your callback routine can be of different formats depending on the argument -result. One result type is raw and it is represented by a simple, not blessed hash table: $io = Bio::Biblio::IO->new('-result' => 'raw'); What other result formats are available depends on the module who reads the citations in the first place. At the moment, the following ones are available: $io = Bio::Biblio::IO->new('-result' => 'medline2ref'); This is a default result format for reading citations by the medlinexml module. The "medlinexml" module is again the default one. Which means that you can almost omit arguments (you still need to say where the citations come from): $io = Bio::Biblio::IO->new('-file' => 'data/medline_data.xml'); Another result format available is for PUBMED citations (which is a super-set of the MEDLINE citations having few more tags): $io = Bio::Biblio::IO->new('-format' => 'pubmedxml', '-result' => 'pubmed2ref', '-data' => $citation); Or, because "pubmed2ref" is a default one for PUBMED citations, you can say just: $io = Bio::Biblio::IO->new('-format' => 'pubmedxml', '-data' => $citation); Both "medline2ref" and "pubmed2ref" results are objects defined in the directory "Bio::Biblio".

o An example script examples/biblio.pl. It has many options and its own help. The relevant options to this IO module are -f (specifying what file to read) and -O (specifying what result format to achieve). o OpenBQS home page: http://www.ebi.ac.uk/~senger/openbqs o Comments to the Perl client: http://www.ebi.ac.uk/~senger/openbqs/Client_perl.html FEEDBACK
Mailing Lists User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists Support Please direct usage questions or support issues to the mailing list: bioperl-l@bioperl.org rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

The rest of the documentation details each of the object methods. Internal methods are preceded with a _ next_bibref Usage : $citation = stream->next_bibref Function: Reads the next citation object from the stream and returns it. Returns : a Bio::Biblio::Ref citation object, or something else (depending on the '-result' argument given in the 'new()' method). Args : none _load_format_module Usage : $class->_load_format_module ($format) Returns : 1 on success, undef on failure Args : 'format' should contain the last part of the name of a module who does the real implementation It does (in run-time) a similar thing as require Bio::Biblio::IO::$format It throws an exception if it fails to find and load the module (for example, because of the compilation errors in the module). _guess_format Usage : $class->_guess_format ($filename) Returns : string with a guessed format of the input data (e.g. 'medlinexml') Args : a file name whose extension can help to guess its format It makes an expert guess what kind of data are in the given file (but be prepare that $filename may be empty). perl v5.14.2 2012-03-02 Bio::Biblio::IO(3pm)
