As an data re-user I want to be able to query Ondemand API for different versions of the article, so that in case of write failure I can re-fetch this particular version to keep the historical data.
Acceptance criteria
I can query the Ondemand API using version identifier to get the particular version of an article.
ToDo
- need to figure out how many revisions are we going to store? all of them?
- what infrastructural changes need to be made in order to support this
- what software changes need to be made in order to support this
