<p>Do you mean expansion in terms of adding more content, or expanding the schema? </p>
<p>Can you give examples of what you are thinking of w.r.t. bioregions and climates? I could certainly think about it :-) I've also created the Local food base (<a href=""></a>), which has the Produce type that can link locations and seasonal months. One way to do what you are thinking is to just use separate schema, one to define the elements &lt;&gt; element needs, and a separate one that is co-typed to say what items are seasonal/local to a region. </p>
<p>I think seasonal plants could be covered by the types in Local food base, but there may be some schema dev to do to create something that describes the regions for animals, e.g. chickens. </p></div>
