NAME

       TM::Serializable::JTM - Topic Maps, trait for reading/writing JSON Topic Map instances.

SYNOPSIS

	 # NOTE: this is not an end-user package,
	 # see TM::Materialized::JTM for common application patterns

	 # reading JSON/YAML:
	 my $tm=TM->new(...);
	 Class::Trait->apply($tm,"TM::Serializable::JTM");
	 $tm->deserialize($jsondata);

	 # writing JSON/YAML:
	 # ...a map $tm is instantiated somehow

	 Class::Trait->apply($tm,"TM::Serializable::JTM");
	 my $yamltext=$tm->serialize(format=>"yaml");

DESCRIPTION

       This trait provides functionality for reading and writing Topic Maps in JTM (JSON Topic Map) format, as defined here:
       <http://www.cerny-online.com/jtm/1.0/>.

       Limitations:

       o   Variants are not supported by TM.

       o   Reification of basenames, occurrences and roles is not supported by TM.

       o   Multiple scopes are not supported by TM.

INTERFACE

   Methods
       deserialize
	   This method take a string and parses JTM content from it. It will raise an exception on any parsing error. On success, it will return
	   the map object.

	   The method understands one key/value parameter pair:

	   o   format (choices: "json", "yaml")

	       This option controls whether the JTM is expected to be in JSON format or in YAML (which is a superset of JSON).

	       If no format parameter is given but the TM::Materialized::JTM trait is used, then the format is inherited from there; otherwise the
	       default is "json".

       serialize
	   This method serializes the map object in JTM notation and returns the result as a string.

	   The method understands one key/value parameter pair:

	   o   format (choices: "json", "yaml")

	       This option controls whether the JTM result should be created in the JSON format or in YAML (which is a superset of JSON).

	       If no format parameter is given but the TM::Materialized::JTM trait is used, then the format is inherited from there; otherwise the
	       default is "json".
