The SEC has released the draft version of the 2019 DEI taxonomy for public review. This taxonomy contains the elements required for the tagging of cover page data for Inline XBRL submissions and is open for public comment until June 6, 2019.
The draft taxonomy can be downloaded and reviewed here: http://www.sec.gov/structureddata/osddrafttaxonomyfiles
To submit a comment on the draft 2019 update to the DEI taxonomy, e-mail StructuredData@sec.gov using “Draft DEI Taxonomy” as the subject of the e-mail. Again comments must be submitted no later than June 6, 2019.
After completion of the public comment period, the taxonomy will be subject to SEC approval. If appropriate, transition guidance for the 2019 update to the DEI taxonomy will be posted on the standard taxonomies page at http://www.sec.gov/page/derataxonomies.
