RFC 309 is an announcement of the 1972 Data and File Transfer Workshop announcement. The suggested reading section has 12 entries, 11 of which are RFCs and the last of which is:
8. Data Language, CCA, NIC # 8208
This document appears difficult to find.
The one non-RFC document is a publication called “Data Language” by Computer Corporation of America, but I can't find something with that exact name online to link.
