Add Bioschemas by proxying Wikidata content (making Google bots happy)

[egonw]

@fnielsen, this is now a finished patch, but if you have additional ideas, plz let me know (if not, please do merge in).

The new design solve the problem of the robots.txt blocking calls and limiting the SEO indexing of Scholia pages:

• a Scholia proxy is defined with the URL pattern /$qid/bioschemas which returns JSON
• the existing base.html uses this new call instead of a call to wikidata.org (with the robots.txt problem)

The extra call is only made when the aspect template has an id=bioschemas holder.

Possibly future optimization:

• property_for_q() calls are replaced by a single properties_for_q(q, {"P235": "key1", "Pxx": "key2", ...})
• 2-3 helper functions get added to simplify the code
• other bits of the page get included in a similar way (like descriptions), making it also available for SEO
• use the Wikidata description as Bioschemas content

@fnielsen, yes, I see the flake issues. I will fix those, when you told me you like the idea.

Should /$qid/bioschemas return HTML? And with content negotiation you can get json?

Should /$qid/bioschemas return HTML?

No, the intention is only JSON.

And with content negotiation you can get json?

Yeah, I guess that would be more correct: only return JSON when asked for JSON, return 415 for any other media type.

So, go ahead?

[egonw]

Okay, I will assume this is a go ahead.

Current tests:

• http://127.0.0.1:8100/Q12024/bioschemas
• http://127.0.0.1:8100/Q18216/bioschemas
• http://127.0.0.1:8100/Q20035886/bioschemas
• http://127.0.0.1:8100/Q21109365/bioschemas

• http://127.0.0.1:8100/Q18618629/bioschemas

These test normal behavior for 6 Bioschemas profiles, prefixing, and list/string variation.

This has been reverted. It was an accidental merge and there are at least two styling errors.
