When properties are nested, the inner properties are removed to form triples leaving the outer property looking rather messy. Eg, from https://www.uniprot.org/uniprot/Q62226 :

<div class="annotation" property="hasPart" typeof="CreativeWork">
<span property="text">Sonic hedgehog protein: The C-terminal part of the sonic hedgehog protein precursor displays an autoproteolysis and a cholesterol transferase activity (PubMed:
<a href="/citations/8824192">8824192</a>, PubMed:
<a href="/citations/7891723">7891723</a>). Both activities result in the cleavage of the full-length protein into two parts (ShhN and ShhC) followed by the covalent attachment of a cholesterol moiety to the C-terminal of the newly generated ShhN (PubMed:
<a href="/citations/8824192">8824192</a>). Both activities occur in the reticulum endoplasmic (PubMed:

Google SDT Tool

Leaves in the text that is removed by Any23; however, it is still not easy to read and has weird bits in it. Better than Any23 though.

Extruct

Behaves in the same way as Google.

Similar effect with hasPart. This time the issue is the markup which creates nodes with no content.

This html:

<div class="annotation" property="hasPart" typeof="CreativeWork">Belongs to the 
  <a href="/uniprot/?query=family:%22hedgehog+family%22&amp;sort=score">hedgehog family</a>.
  <span class="attribution ECO305">
    <span class="attributionHeader tooltipped" title="Manual assertion inferred by 
    curator">Curated
    </span>
  </span>
</div>

Produces the following raw triples:

genid-2f27fdee3aaf4285a4db8253476df489-n61  http://www.w3.org/1999/02/22-rdf-syntax-ns#type  http://schema.org/CreativeWork .
http://purl.uniprot.org/uniprot/Q62226  http://schema.org/hasPart  genid-2f27fdee3aaf4285a4db8253476df489-n61 .

I convert to:

http://bioschemas.org/crawl/v1/30/www.uniprot.org/uniprot/Q62226/1168557303  http://www.w3.org/1999/02/22-rdf-syntax-ns#type  http://schema.org/CreativeWork .

Thus we no longer have blank nodes BUT we do have nodes with basically no information. On this single page there seems to be more than 10 instances of this. Ultimately produces a very cluttered and unuseful page.

Google SDT Tool

Same result:

Notice the order in the HTML is Nucleus then Cytoskeleton, which is the order Google has too. HOWEVER, the order is reversed by any23. Furthermore, notice how much of the text found by Google is not detected by Any23.

ALSO notice that much of the text inside the HTML has completely gone from both Google and any23. E.g., The HTML says "The cytoskeleton is a dynamic three-dimensional structure that fills the cytoplasm of cells", but this is missing from both Google and any23.
