In February 2018, AFNOR, the French national organization for standardization, published a recommandation standard to facilitate IP data exchanges, referenced NF X50-276.
The first part (NF X50-276-1) presents recommandations in terms of IP data exchanges.
The second part (NF X50-276-2) details the technical details for practical implementation.
Both documents are only available in French language for the time being.
