For ontologies: RDF-XML

I'm not sure I understand the question.  Data can be sitting as RDF/XML or Turtle before being loaded into a triple store (TS). At that time, it is in the TS's native data structures, not in any serialization format.  If someone decides to export it and what was loaded as turtle might be exported at RDF/XML or N-quads.

For our corporate work, we generally use Turtle. We use n-quads if we want to save out and re-import triples. For certain purposes it is convenient to use N-triples.

So say we create a TS for a client with 1B  triples.  We loaded turtle files into the TS.
Two other groups decide they want to use those triples in their own TSs driving different applications. One exports to RDF/XML and the other exports to N-Quad. Some of these files are thrown away as part of ETL, others are saved for archival purposes.

What question do you want an answer to?
What would the answer be?

Options:

1. RDF/XML

2. Turtle

3. N Triples (e.g. in a quad store)

4. JSON-LD

5. Structured Data Blocks in Script tags aka "Data Islands" (e.g. used in SEO)*

6. Other

The word "most widely" here is open to interpretation, and I would love to hear subjective or anecdotal points of view.  Looking for meaningful deployments.

Any links to stats would be really helpful!

Thanks!
