Open Source Drives Digital Twin Adoption
transformative business value for manufacturers through digital transformation ” 35 . One of its goals is to realize interoperability via collaboration and standardization . Digital twins play an important role in this effort . The focus in this area is on so-called smart manufacturing ( SM ) profiles . An OPC UA information model serialization was chosen for these profile specifications .
Together with the OPC Foundation , CESMII is working on the UA Cloud library
36 . The goal is to provide open data models via a globally hosted cloud database . These data models shall be useable in Digital Twin implementations . SM Profiles , a code sample for the CESMII API , and more are available in CESMII GitHub repository
( https :// github . com / cesmii ).
Comparison of Activities and Organizations
As the organizations introduced above share a similar goal – provide the foundations for an interoperable Digital Twin – they differentiate themselves in the focus of their activities as well as how “ open ” they are . Table 1 summarizes the activities of the organizations mentioned in this paper , highlighting their main contribution and focus 37 .
