I wish to have my plugin store metadata for each blog in a network (or just one if single site install). Most of the Google results are for post_meta and user_meta but I really need site_meta which does not appear to be the same (only a get method). The data is generally going to be of the form:

$metadata['this']['foo'] = 'something';
$metadata['this']['bar'] = 'one thing';
$metadata['that']['foo'] = 'mum';
$metadata['that']['bar'] = 'dad';

What is the best way to store this?

Options are site specific, so you just need to use update_option() and get_option().

The network-wide equivalents are update_network_option() and get_network_option(). Note that update_site_option() is just a wrapper for update_network_option(), and is an older name from when a multisite network was (confusingly) called a 'site'. The same applies for get_site_option().
