+Build a RAG data layer by loading and processing data from "knowledge_base.json", "video_transcript.json", and "youtube_transcripts (1).json", then consolidating and exporting the processed chunks into a unified "rag_data_layer.json" file.

+## Load and Process Knowledge Base

Then, I will load the `knowledge_base.json` file, initialize an empty list to store processed chunks, and iterate through each item to extract, transform, and derive the required information such as URL, text, source type, language, topic, and a unique ID, as per the instructions.

I will initialize an empty list, extend it with each of the processed chunk lists, print the total count for verification, and finally, save the combined list to 'rag_data_layer.json' with proper JSON formatting.

+
+### Subtask:
+Confirm that the RAG data layer has been successfully built and exported into a unified JSON file, ready for further use in the hackathon.
+
+## Summary:
+
+### Q&A
+Yes, the RAG data layer has been successfully built and exported into a unified JSON file named `rag_data_layer.json`, containing all processed data and ready for further use in the hackathon.
+
+### Data Analysis Key Findings
+*   **Knowledge Base Processing:** The `knowledge_base.json` file was loaded, and its content was processed to extract URLs, content (mapped to 'text'), source type ('blog\_article'), language (derived from URL as 'ca' or 'es'), and a derived topic. A total of 28 knowledge base chunks were successfully processed.
+*   **Breathing Transcript Processing:** The `video_transcript.json` file was specifically processed as a "breathing transcript". Its 'text' content was extracted, and fixed metadata values were assigned: `url` as 'https://video.local/breathing\_exercise', `source_type` as 'breathing\_video', `language` as 'es', and `topic` as 'anxiety'. A single (1) breathing transcript chunk was processed.
+*   **Legal Webinar Transcript Processing:** The `youtube_transcripts (1).json` file was specifically processed as a "legal webinar transcript". Its 'video\_url' was mapped to 'url', 'content' to 'text', and fixed metadata values were assigned: `source_type` as 'legal\_webinar', `language` as 'es', and `topic` as 'legal'. A single (1) legal webinar chunk was processed.
+*   **Consolidation and Export:** All processed chunks from the knowledge base, breathing transcript, and legal webinar were consolidated into a single list. This unified list contained a total of 30 chunks.
+*   **Final Output:** The consolidated data layer, comprising 30 chunks, was successfully exported to `rag_data_layer.json` in a well-formatted JSON structure.
+
+### Insights or Next Steps
+*   Consider implementing a more dynamic and robust topic extraction method, potentially leveraging natural language processing (NLP) models, to reduce reliance on URL patterns or fixed assignments, especially as data sources grow.
+*   For future iterations, centralize the metadata schema and processing rules to ensure consistency and easier maintenance across diverse data sources, instead of having source-specific hardcoded values.
