Relations of documents

[max298]

I would like to add documents to LightRAG that have a relationship with each other. For example, I have a main document with an attached appendix. I want to be able to update the appendix while keeping the main document unchanged.

Is something like this possible? From what I understand, uploading the appendix as a separate document won't work, because it would not create any relation to the main document. On the other hand, merging the main document and the appendix into a single file and then deleting and re-uploading everything every time the appendix changes would consume a huge number of tokens, assuming the appendix will be updated quite often.

So is there any way to add documents which are related to existing documents, or even direct children of existing documents?
