43 =head1 NAME
44
45 Bio::Tools::WWW - Bioperl manager for web resources related to biology.
46
47 =head1 SYNOPSIS
48
49 =head2 Object Creation
50
51 use Bio::Tools qw(:obj);
52
53 $pdb = $BioWWW->home_url('pdb');
54
55 There is no need to create a new Bio::Tools::WWW.pm object when the
56 C<:obj> tag is used. This tag will import the static $BioWWW object
57 created by Bio::Tools::WWW.pm into your name space. This saves you
58 from having to call C<new Bio::Tools::WWW>.
59
60 You are free to not use the :obj tag and create the object as you
61 like, but a Bio::Tools::WWW object is not configurable; any given
62 script only needs a single copy.
63
64 =head1 INSTALLATION
65
66 This module is included with the central Bioperl distribution:
67
68 http://bio.perl.org/Core/Latest
69 ftp://bio.perl.org/pub/DIST
70
71 You also need to define URLs for the following variables in this package:
72
73 $Not_found_url : Generic page to show in place of a 404 error.
74 $Tmp_url : Web-accessible site that is Used for scripts that
75 need to generate temporary, web-accessible files.
76 The files need not necessarily be HTML files, but
77 being on the same disk as the server will permit
78 faster IO from server scripts.
79
80 =head1 DESCRIPTION
81
82 Bio::Tools::WWW is primarily a URL broker for a select set
83 of sites related to bioinformatics/genome analysis. It
84 definitely represents a biased, unexhaustive set.
85 It might be more accurate to call this module
86 "Bio::Tools::URL.pm". But this module does handle some non-URL
87 things and it may do more of this in the future. Having one
88 module to cover all biologically relevant web utilities
89 makes it more convenient, especially at this early stage
90 of development.
91
92 Maintaining accurate URLs over time can be challenging as
93 new web sites spring up and old sites are re-organized. Because
94 of this fact, the URLs in this module are not guaranteed to be
95 correct or exhaustive and will require periodic updating.
96
97 =head2 URL Management
98
99 By keeping URL management within Bio::Tools::WWW.pm, other generic
100 modules can easily access a variety of different web sites without
101 having to know about a potential multitude of specific modules
102 specialized for one database or another. An alternative approach would
103 be to have addresses defined within modules specialized for different
104 web sites. This, however, may create maintenance headaches when updating
105 these addresses.
106
107 =head2 Complex Websites
108
109 Websites with complex datasets may require special treatment
110 within this module. As an example,
111 URLs for the Saccharomyces Genome Database are clustered
112 separately in this module, due to (1) the different ways to
113 access information at this database and (2) the familiarity
114 of the developer with this database. The Bio::SGD::WWW.pm inherits from
115 Bio::Tools::WWW.pm to permit access to the URLs provided by Bio::Tools::WWW.pm
116 and to SGD-specific HTML and images.
117
118 The organization of Bio::Tools::WWW.pm is expected to evolve as
119 websites get born, die, and mutate their APIs.

433 =head2 home_url
434
435 Usage : $BioWWW->home_url(<string>)
436 Purpose : To obtain the homepage URL for a biological database or resource.
437 Returns : String containing the URL (including "http://")
438 Argument : String
439 : Currently acceptable arguments are:
440 : bioperl bioperl-schema biomoo bsm ebi emotif entrez
441 : expasy mips mmdb ncbi pir pfam pdb geneQuiz
442 : molMov pubmed sacch3d sgd scop swissProt webmol ypd
443 Throws : Warns if argument cannot be resolved to a URL.
444 Comments : The URLs listed here do not represent a complete list.
445 : Expect this to evolve and grow with time.

460
461
462
463 =head2 search_url
464
465 Usage : $BioWWW->search_url(<string>)
466 Purpose : To provide a URL stem for a search engine at a biological database
467 : or resource.
468 Returns : String containing the URL (including "http://")
469 Argument : String
470 : Currently acceptable arguments are:
471 : 3db embl cath ec1 ec2 ec3 emotif_id entrez gb1 gb2
472 : gb3 gb4 gb5 pdb medline mmdb pdb pdb_coord pfam pir_acc
473 : pdbSum molMov swpr swModel swprSearch scop scop_pdb scop_data
474 : ypd
475 Throws : Warns if argument cannot be resolved to a URL.
476 Comments : Unlike the homepage URLs, this method does not return a complete
477 : URL but a stem which must be further modified, typically by
478 : appending data to it, before it can be used. The data appended
479 : depends on the specific URL; typically, it is a database ID or
480 : other unique identifier.
481 : The requirements for each URL will be described here eventually.
482 :
483 : The URLs listed here do not represent a complete list.
484 : Expect this to evolve and grow with time.
485 :
486 : Given this complexity, it may be useful to provide special methods
487 : for these different URLs. This would however result in an
488 : explosion of methods that might make this module less
489 : maintainable and harder to use.

507 =head2 stem_url
508
509 Usage : $BioWWW->stem_url(<string>)
510 Purpose : To obtain the minimal stem URL for searching a biological database or resource.
511 Returns : String containing the URL (including "http://")
512 Argument : String
513 : Currently acceptable arguments are:
514 : emotif entrez pdb
515 Throws : Warns if argument cannot be resolved to a URL.
516 Comments : The URLs stems returned by this method are much more minimal than
517 : this provided by search_url(). Use of these stems requires knowledge
518 : of the CGI scripts which they invoke.

944 : 2) if a tag is split over multiple lines and this method is
945 : used to process one line at a time.
946 :
947 : Without fast mode, large HTML files can take exceedingly long times to
948 : strip (e.g., 1Meg file with many tags can take 10 minutes versus 5 seconds
949 : in fast mode. Try the swissprot yeast table). If you know the HTML to be
