Corpus Data Stats

[bootsa]

Is your feature request related to a problem? Please describe.
Chris from OK Maps has requested we provide stats and charts describing the state of the data in the corpus as it will appear to them (primarily from Wikidata but maybe also from CrossRef, etc)

Describe the solution you'd like
A series of queries (SPARQL) that return usable data that can be charted - possibly part of the dataWrangler project.

Describe alternatives you've considered
Taking the data and putting in spreadsheets to chart - but that's not very malleable, customisable or easily updated.

Additional context

Need to come up with a list of useful stats:

• Entries with percentage of authors as string, entry with monolithic name, entry with first name and last name
• Percentage of entries with and without DOIs
• Spread and count of keywords
