Summary of Changes

Hello @susmitakumari-art, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly expands the available data on student financial aid by incorporating detailed statistics from the IPEDS database. It provides a multi-year view of student cohorts, their financial aid status, and subsequent graduation outcomes across various types of educational institutions. This new data enhances the ability to analyze trends and impacts within the higher education financial landscape.

Highlights

• New IPEDS Financial Aid Data: Integration of comprehensive student financial aid data from the National Center for Education Statistics (IPEDS) for multiple cohort years (2010-2013 through 2018-2021).
• Detailed Metrics: The dataset includes adjusted cohort sizes, number of students receiving awards, and graduation rates, categorized by institution control, level, and specific aid types (Pell Grant, Direct Subsidized Loan, or no aid).
• Data Processing Artifacts: Addition of structured metadata, property-value mappings, and template MCF files to facilitate the ingestion and interpretation of the new statistical variables.
• Spell Check Observations: Log files indicate minor spell check errors for terms like "Pell" and "chort" (intended as "cohort") during the data processing, which were likely handled or noted.

Code Review

This pull request introduces a large number of files to ingest student financial aid data from IPEDS. While the effort is appreciated, there are significant systemic issues across the PR that need to be addressed to ensure data quality, consistency, and maintainability. Key problems include: an inconsistent and confusing directory structure (e.g., 2018_2021 nested within 2016_2019), inconsistent file naming conventions, numerous data formatting errors in the input CSVs (like split headers and extra spaces), and critical typos in schema definitions and mappings (e.g., AdjustedChort instead of AdjustedCohort). Additionally, several log files and output files are misplaced, and important errors from the import process appear to have been ignored. I've added specific comments highlighting examples of these recurring issues. A thorough cleanup is highly recommended before this can be merged.
