2. Architecture
Architectural Quanta (AQ) is the minimum constituent unit of architecture in distributed data management. Data Product is the AQ of data mesh. To address Data Product’s interoperability problem, Open Dataspaces newly introduces the concept of “Ontology Product”, which has a symmetric relationship with Data Product. Open Dataspaces then designates both Data Product and Ontology Product together as the constituent unit AQ. This is the greatest differentiator from the data mesh paradigm. Open Dataspaces calls this AQ paradigm the Double-Product Quanta Model (DPQM). (Figure 1)

ODS-RAM consists of four layers and four perspectives, which represent a functional decomposition of the DPQM defined as the minimum unit of architecture. (Figure 2)
