NAME

Net::WoRMS bundles functionalities for the tool query-worms.

VERSION

version 1.1

SYNOPSIS

Net::WoRMS bundles WEB access, parsing and fomatting capabilities for the tool query-worms. The the modul was built around the the module SOAP::Lite and is implemented as a Moo object.

MODULE DEPENDENCIES

The module uses the packages:

Data::Dumper

Debugging purposes

Moo

Object oriented extension for the module

MooX::Types::MooseLike::Base

Minimal type system for Moo

SOAP::Lite

is used for the WEB access and parsing capabilities to retrieve data from www.marinespecies.org.

Syntax::Keyword::Match -- to end the switch case madness

GLOBAL VARIABLES and CONSTANTS

$END_POINT = 'http://www.marinespecies.org/aphia.php?p=soap'

The access point to retrieve data via the Simple Object Access Protocol.

$APHIA_NS = 'http://aphia/v1.0'

Namespace and Namespace URI. In the development context these variables are considered as a constants. There are methods to change these values but never tested.

$FORMAT ='TEXT'

FORMAT defines the default output format.

@ORDER_SCORE = qw/APHIA_ID ... /

The array holds field names for SQL related output.

@ORDER_DOT = qw/APHIA.ID ... /

The array holds field names for TEXT and CSV related output.

%FORMATS = ( TEXT => 1, SQL => 2, CSV => 3);

The format hash mostly for validation.

%ORDER_HASH

Dictionary to sort and translate the retieved field names from the WoRMS database and bring them into a consistent form.

@TYPE

Type array corresponding to @ORDER_SCORE/@ORDER_DOT and the %ORDER_HASH to handle quotes and NULL values.

FIELDS

Debug: BOOL

Flag to switch to the debugging mode.

Format: STR

Field holds the current output format TEXT|SQL|CSV.

EndPoint: STR (URI)

The current SOAP endpoint defaults to $END_POINT.

AphiaNS and AphiaURI: STR (URI)

The current namespace and namespace URI, defaulting to $APHIA_NS.

Soap

The SOAP access client instance generate by SOAP::Lite.

METHODS

init()

Initializes the SOAP client.

NOTE1:

The function changeEndPoint($uli), changeAphiaURI($uri) and changeAphiaNS($uri) as well as changeDebug($flag), changeFormat($format) must be used before the initialization phase.

CHANGE METHODS

changeEndPoint($uri)

Change the end point for the soap client (don't change).

changeAphiaURI($uri)

Change the namespace URI for the soap client (don't change).

changeAphiaNS($uri)

Change the namespace soap soap client (don't change).

changeDebug($flag)

Demand debugging capabilities.

changeFormat($format)

Changes the output format. Valid formats are TEXT|CSV|SQL.

getFormats()

Get the format dictionary for validation.

QUERY METHODS

checkSoap()

Check if the soap client is running. The function stops the program (die ...) in case of an error.

checkError($soapResponse)

Checks the the SOAP query result. The function stops the program in case of an communication error.

checkDebug($queryResult)

Prints the query result (dictionary) via Data::Dumper to STDERR if the debugging flag is set.

searchSpeciesID($name, $print)

Function to find a species by a certain name. The if the flag $print is set. The result will be written to STDOUT on the given format.

getRecordByID($aphiaID)

Retrieves a record for a given AphiaID and returns a dictionary or 'dies' with an error.

getBlockChildrenByID($AphiaID, $offs)

Retrieve a set of taxon records under an given AphiaID for a devine offset in the query ensemble .The offset addresses a paging pattern.

getChildrenByID($aphiaID)

Retrieves all children under a given AphiaID using the method getBlockChildrenID(...) and prints the result to STDOUT using the method printRecord(...).

printRecord($record, $first, $last, $spc)

Prints a record to SDTOUT and handles inentation by $spc as well as header and trailing aspects by using the $first and $last flags.
