Standardized storage systems based on SS-MIX2 specification have been installed at many healthcare sites in Japan. The specification document for it was in version 0.96 and it was pointed out that it has ambiguous descriptions. And standards which SS-MIX2 is based on have been updated. Therefore, JAMI worked with JAHIS, HL7-Japan, and SS-MIX Consortium to revise the document since July, 2014.
JAMI released a new specification document in version 1.2 and related documents. Unfortunately, these are in Japanese. But JAMI recenty released an English document titled "SS-MIX2 Standardized Storage" Explanation of Structure and Guidelines for Implementation Ver.1.2.
