Suppose i have a retrieved node, how to access the metadata for the same

[amitguptadumka]

suppose i retrieved top 1 for a query using:
node=retriever.retrieve("my query")
now i want to access the source node_id from the node. I am able to extract node.text, node.score,node.metadata but i am not able to access node.relationships how to access this since i need to use source node under this?

Sample node content below:
node= NodeWithScore(node=TextNode(id_='27066102-68dd-4fc3-9d22-0cc6f2e331fa', embedding=None, metadata={''}, excluded_embed_metadata_keys=[], excluded_llm_metadata_keys=[], relationships={<NodeRelationship.SOURCE: '1'>: RelatedNodeInfo(node_id='c89aa4ed-afa7-4427-9059-7e1160762012', node_type=None, metadata={}, hash='bb3bb8f48548ea53692aad238040733568567d6e6cf114d9b6803aafd9f98f61'), <NodeRelationship.NEXT: '3'>: RelatedNodeInfo(node_id='34e0dfd6-d35e-407b-a4a1-3768ee407e3e', node_type=None, metadata={'}, hash='c996de0cad9ca18928caf0173b3864c5a8e22d1edb110272e66ed6f778151caf')}, hash='6933bd9f34baf7ccec9a52f22edb8cd6c6b10096bce04140f8ef0409c4d6aba1', text=' Some text here.', start_char_idx=None, end_char_idx=None, text_template='{metadata_str}\n\n{content}', metadata_template='{key}: {value}', metadata_seperator='\n'), score=0.8068367655303894)

Hello @amitguptadumka,

It's good to see you again and I hope you're doing well.

From your question, it seems you're trying to access the relationships property of a NodeWithScore object, specifically the source_node.

In the LlamaIndex codebase, the relationships property of the NodeWithScore object is a dictionary that maps relationships to other node information. The keys of this dictionary are of the type NodeRelationship, which is an enumeration with the following possible values: SOURCE, PREVIOUS, NEXT, PARENT, and CHILD. The values associated with these keys are of the type RelatedNodeType, which can either be a single RelatedNodeInfo object or a list of RelatedNodeInfo objects.

To access the source_node from the relationships property, you can use the source_node property of the BaseNode class. Here's an example of how you can do this:

source_node = node.node.source_node

This will return a RelatedNodeInfo object if a source node exists, or None if it doesn't.

Please note that if the associated value is a list, it raises a ValueError, as the source node should be a single RelatedNodeInfo object.

You can find more information about this in the llama_index/schema.py file.

I hope this helps! If you have any more questions, feel free to ask.

Best,
Dosu
