Sync Google Drive files to an InfraNodus Knowledge Graph

This template can be used to sync the files in your Google drive to a new or existing InfraNodus knowledge graph. The InfraNodus graph will then reveal the main topics and ideas in your collection of documents and show the content gaps in them. You can also use the built-in AI to converse with the documents. You can also access the InfraNodus Graphs via its GraphRAG API to re-use them in your other n8n workflows for high-quality content retrieval and knowledge base optimization. The template showcases the use of multiple n8n nodes and processes: - Syncing documents from a Google Drive folder / extracting them - text extraction from files - optional: high-quality PDF conversion using ConvertAPI - InfraNodus knowledge graph generation Note: If you want to upload files from your Google drive to an InfraNodus graph, check out our other workflow How it works Here's a description of this workflow step by step: - Wait for new file(s) to appear in the Google drive folder - Reiterate through each file - Retrieve the new file from the Google drive - For each file found: reiterate the workflow and - Identify the type of the file (TXT, PDF, Markdown) - For TXT and Markdown files extract the text data - For PDF files use a special PDF to Text convertor to extract the text data. (Optional: using ConvertAPI for better quality PDF conversion) - Forward everything to the InfraNodus graphAndStatements API endpoint with the name of the new graph, the text field with the text data, the text settings, and doNotSave=false to create a new graph - Reiterate through another file. How to use You need an InfraNodus GraphRAG API account and key to use this workflow. - Create an InfraNodus account - Get the API key at and create a Bearer authorization key for the InfraNodus HTTP nodes. - Use that API key to set up authorization for the InfraNodus tool in the workflow. - If you want to upload the files to an existing graph, you should copy its name from InfraNodus. Otherwise you can specify any name you want. Requirements - An InfraNodus account and API key - A Google Drive account and authorization (you will need to set it up via Google Cloud using the n8n instructions provided in the Google Drive node). Customizing this workflow You can use Dropbox instead of Google Drive. You can also modify this workflow slightly to make it Upload the files from a Google Drive when the new files appear in it.
