NAME ^

BPM::XPDL - XPDL access

INHERITANCE ^

 BPM::XPDL
   is a XML::Compile::Cache
   is a XML::Compile::Schema
   is a XML::Compile

SYNOPSIS ^

  my $xpdl = BPM::XPDL->new(version => '2.1');
  $xpdl->importDefinitions(...);
  my $xml  = $xpdl->writer($sometype)->($doc, $perldata);

  my ($type, $data) = $xpdl->from('data.xml');
  my ($type, $data) = BPM::XPDL->from('data.xml');
  print "Root type: $type\n";
  print Dumper $data;    # from Data::Dumper

  $xpdl->addKeyRewrite('PREFIXED');
  my $xml = $xpdl->create($data);
  print $xml->toString(1);

DESCRIPTION ^

This module provides access to the Process Description Language, as defined by the WfMC, the Workflow Management Coalition (wfmc.org) You can read and create() these XPDL files with one simpe method.

All versions of the specification are supported. It will convert older versions into newer versions if you want to. See from().

Limitiations

The XPDL files may contain additional external type definitions, which are not imported/included in the specification. You need to import those explictly by hand. See t/20sample.t

TypeDeclarations are part of the interpretation of the messages which are exchanged between the Applications, and therefore not interpreted by this module.

METHODS ^

Constructors

$obj->from(XMLDATA, OPTIONS)

BPM::XPDL->from(XMLDATA, OPTIONS)

Read an XML message, in any format supported by XML::Compile method dataToXML(): string, file, filehandle, and more. Returned is a list of two: the type of the top-level element plus the data-structure.

When called as instance method, the data will automatically get converted to the version of required by the object. When called as class method, the version of the top-level element will determine the returned version automatically (which may give unpredictable versions as result).

When the method is called as class method, then a temporary instance is created. Creating an instance is (very) slow.

example:

  my $xpdl          = BPM::XPDL->new(version => '2.1');
  my ($type, $data) = $xpdl->from('data.xml');

or

  my ($type, $data) = BPM::XPDL->from('data.xml');

Other

$obj->create(DATA)

Pass a correctly constructed Perl data-structure, which maps to a xpdl:Package type, and it will produce XML for it (returns an XML::LibXML::Document object).

Be warned that the output may contain deprecated constructs. Accidentally, the non-deprecated versions usually match better on the provided data.

  my $xml = $xpdl->create($data);
  print $xml->toString(1);
