Similarly, annotations that allow support for system::chain::transaction (for example) look like this:

DEFINE_JSON_TO_TAG(transaction)
{
    return
    {
        value.at("version").to_number<uint32_t>(),
        value_to<inputs>(value.at("inputs")),
        value_to<outputs>(value.at("outputs")),
        value.at("locktime").to_number<uint32_t>()
    };
}

DEFINE_JSON_FROM_TAG(transaction)
{
    value =
    {
        { "version", instance.version() },
        { "inputs", value_from(*instance.inputs_ptr()) },
        { "outputs", value_from(*instance.outputs_ptr()) },
        { "locktime", instance.locktime() }
    };
}

DEFINE_JSON_TO_TAG(transaction::cptr)
{
    return to_shared(tag_invoke(to_tag<transaction>{}, value));
}

DEFINE_JSON_FROM_TAG(transaction::cptr)
{
    tag_invoke(from_tag{}, value, *instance);
}
