@Srikanth_S I believe there actually are some independent administration and integration tools/utilities made by the Italian CRS4 research group CRS4 · GitHub perhaps the things under
GitHub - crs4/openEHR-tool: Tool for openEHR or
GitHub - sasurfer/openEHR-tool: Tool for openEHR
Perhaps @mdrio and his colleagues know more
P.s. also by that group: Tool for mapping data to openEHR compositions
