Dear Marcus,

I took the liberty of adding your example to the TDM wiki here:

That is the best place for further discussion. I have also added your
initial comments there and posed a follow-on question about putting a
tp:PublicationCitation under every spm:hasInformation element when you want
to cite a source for its content.

Best regards,

I have prepared a simple SpeciesPage example based on the current  

I hope this helps and also that it's really correct. At least it  
validates with w3c's validator.
You can also view it with the new AJAX based OpenLink RDF browser:

two things struck me when writing this example:
- where do I put a PublicationCitation? I would want to cite all  
sources for every information and I dont know where/how. Is this  
missing or part of the base/core ontology already?
- hasInformation is a bit redundant, but the validator did complain  
when I declared all InfoItems under a single hasInformation node. Was  
this intended? I guess yes, cause otherwise the InfoItems would have  
to be properties.

best wishes
