SYNOPSIS

DESCRIPTION

Map Meta Data

INTERFACE

Methods

sync_in

$ms->sync_in ($path)

A whole subtree of the map repository can be sync'ed in, i.e. synchronized with contents in an associated resource. If this method is triggered with a particular path, then the map there will be (a) synced in, (b) queried for sub-maps and (c) these sub-maps will be instantiated. Recursively, these submaps will be sync'ed in, etc. All these sub maps will be mounted under this branch of the tree.

When a map is instantiated, its implementation package will be extracted from the parent map using a implementation characteristic. The resource URL will be determined from one of the subject indicators, the base URI will be determined from the subject address of the map topic. If any of these are missing, this particular sub-map is ignored.

Example: Let us assume that a map has a baseuri http://whatever/ and a resource URL http://example.org/here.xtm. It is a materialized map using the XTM driver. If this map is mounted into a root map under /foo/, then the entry will take the form (using AsTMa= 2.0 as notation):

foo isa topicmap
~ http://example.org/here.xtm
= http://whatever/
implementation: TM::Materialized::XTM
