How do and if null case
Example:

IF $node.object.data_map.author <> Null
<h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3>
else <h3>No Author</h3>

Sorry For the newbie Question. Can't figure out how to check variables.

I don't know if I am one the right track... This is what I have tried so far....

{switch match=$node.object.data_map.author.data_text}
{case match=""}
<h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3>
{/case}
{/switch}

I tried this too....

{section show=$node.object.data_map.author|null( )
<h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3>
{/section}

Well I figured it out after all. Here is what I did.

{section show=ne($node.object.data_map.author.content)}
<h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3>
{/section}

But i think this is only suitable for 'tiny' conditions...
