NAME

       TM::ResourceAble::MemCached - Topic Maps, Memcached server backend

SYNOPSIS

	   use TM::ResourceAble::MemCached;
	   use Fcntl;
	   # create/reset new map
	   my $tm = new TM::ResourceAble::MemCached (
		       baseuri => 'http://whereever/',
		       servers => [ localhost:11211 ],
		       mode    => O_TRUNC | O_CREAT,
		    );

	   # use TM interface

	   # open existing map
	   my $tm = new TM::ResourceAble::MemCached (
			baseuri => 'http://whereever/',
			servers => [ localhost:11211 ],
		    );

DESCRIPTION

       This package implements TM using a memcached server farm as backend. You should be able (without much testing, mind you, so it is
       EXPERIMENTAL) to perform all operations according to the TM interface.

       NOTE: The implementation is using the TIE technique (perltie via Tie::StdHash), so maybe there are problems lurking.

       Of course, a set of memcacheds can store any number of maps. To keep them separate, the baseuri is used, so make sure every map gets its
       own baseuri.

INTERFACE

   Constructor
       The constructor expects a hash with the following keys:

       servers (default: none)
	   The value must be a reference to an array of strings, each of the form host:port. If there is no such list, then the constructor will
	   fail.

       mode (default: O_CREAT)
	   The value must be a value from Fcntl to control

	   o   whether the map should be created ("O_CREAT") when it does not exist, and/or

	   o   whether the map should be cleared ("O_TRUNC") when it existed before.

       All other options are passed to the constructor chain of traits (TM::ResourceAble) and superclasses (TM).

NAME

       TM::Materialized::MLDBM2 - Topic Maps, DBM Storage (synchronous)

SYNOPSIS

	  NOTE: THIS PACKAGE IS NOW DEPRECATED
	  NOTE: USE TM::ResourceAble::MLDBM INSTEAD

	  use TM::Materialized::MLDBM2;
	  {
	   my $tm = new TM::Materialized::MLDBM2 (file => '/tmp/map.dbm');
	   # modify the map here.....

	   } # it goes out of scope here, and all changes are written back automagically

	  # later in the game
	  {
	   my $tm = new TM::Materialized::MLDBM2 (file => '/tmp/map.dbm');
	   # we are back in business, no sync necessary
	   }

DESCRIPTION

       This package just implements TM with a BerkeleyDB store. Unlike TM::Materialized::MLDBM this module does not need explicit synchronisation
       with the external resource (the DBM file here).	It ties content-wise with the DBM file at constructor time and unties at DESTROY time.

       The advantage of this storage form is that there is little memory usage. Only those fractions of the map are loaded which are actually
       needed. If one has very intense interactions with the map (as a query processor has), then this storage technique is not optimal.

INTERFACE

   Constructor
       The constructor expects a hash with the following keys:

       file (no default)
	   This contains the file name of the DBM file to tie to.
