Unsure how tensor order is defined in GGUF for graph reconstruction

[CharlieASExp]

Hi, trying to alter my existing GGML code in a custom framework to be a GGUF reader instead. In the GGML there were sources for each node so I could create a graph of nodes and leaves etc with up to 10 sources for each node, I can't see any similar sources in GGUF and have been trawling through the source code for an explanation with no luck. Is it somewhere in the metadata?

Any help would be greatly appreciated thanks.
