It says on your website home page: “Each revision is archived to build a real-time database.” and “Each data series has a unique ID. You can retrieve the exact dataset researchers used, and reproduce the same results using their code.”. How can I access historical data revisions? For example, I’m looking for a way to access Euro Area GDP initial publications data as of the year of interest, i.e. not the latest after data revisions were made. For example, OECD publishes their data vintages this way: https://stats.oecd.org/Index.aspx?DataSetCode=MEI_ARCHIVE#. Is there a way to retrieve this data in DBNomics?
