+# Federal Student Aid Document Loader Dataset
+
+This dataset demonstrates document loading and processing techniques using LangChain's document loaders in an educational pipeline. It contains processed pages from official Federal Student Aid handbooks for the 2025-26 processing year.
+
+## Dataset Details
+
+### Dataset Description
+
+This dataset contains 269 processed document pages extracted from four Federal Student Aid handbook volumes using LangChain's PyPDFDirectoryLoader. Each record includes the extracted text content and comprehensive metadata about the source document and processing pipeline.
+
+The dataset serves as an educational example of:
+- Document loading with LangChain
+- Workflow orchestration with Prefect
+- Metadata standardization across document sources
+- Preparation for RAG (Retrieval Augmented Generation) systems
+
+- **Curated by:** Educational demonstration project (dwb2023)
+- **Language(s):** English
+- **License:** MIT
+- **Source Documents:** Federal Student Aid Handbooks 2025-26
+
+### Dataset Sources
+
+- **Repository:** [langchain-dataset-loaders](https://github.com/user/langchain-dataset-loaders)
+- **Original Documents:** Federal Student Aid Partner Connect Knowledge Center
+- **Processing Pipeline:** LangChain + Prefect orchestration example
+- **Related Tutorial:** [Document Loader Pipeline Guide](https://github.com/user/langchain-dataset-loaders/blob/main/README.md)
+
+## Uses
+
+### Direct Use
+
+This dataset is designed for educational purposes to demonstrate:
+
+1. **Document Processing Pipelines**
+   - Learning LangChain document loader patterns
+   - Understanding metadata enrichment
+   - Practicing document chunking and retrieval
+
+2. **RAG System Development**
+   - Building question-answering systems over financial aid documentation
+   - Creating semantic search applications
+   - Developing document intelligence tools
+
+3. **Educational Research**
+   - Studying federal student aid policies and procedures
+   - Analyzing government document structure
+   - Understanding financial aid eligibility requirements
+
+### Out-of-Scope Use
+
+- **Not for production financial aid decisions** - Use official FSA sources for actual student aid determinations
+- **Not for legal advice** - Consult official regulations and qualified professionals
+- **Not for current academic year processing** - This dataset reflects 2025-26 guidelines which may be outdated
+
+## Dataset Structure
+
+Each record contains two main fields:
+
+- **`page_content`** (string): Extracted text content from PDF pages (277-5,300 characters)
+- **`metadata_json`** (string): JSON-formatted metadata including:
+  - Source file information (`source`, `total_pages`, `page`, `page_label`)
+  - Processing details (`loader_type`, `load_timestamp`)
+  - Document creation metadata (`producer`, `creator`, `creationdate`, `moddate`)
+
+### Example Record
+
+```json
+{
+  "page_content": "Volume 7 The Federal Pell Grant Program Introduction This volume of the Federal Student Aid Handbook provides information to assist schools in determining student eligibility...",
+  "metadata_json": "{\"producer\": \"GPL Ghostscript 10.00.0\", \"creator\": \"wkhtmltopdf 0.12.6\", \"source\": \"data/raw/The_Federal_Pell_Grant_Program.pdf\", \"total_pages\": 65, \"page\": 0, \"loader_type\": \"pdf\", \"load_timestamp\": \"2025-07-03T15:05:37.091391\"}"
+}
+```
+
+## Dataset Creation
+
+### Curation Rationale
+
+This dataset was created to provide a realistic, domain-specific example for learning document processing techniques. Federal Student Aid handbooks were chosen because they:
+
+- Represent real-world government documents with complex formatting
+- Contain structured information suitable for Q&A applications
+- Provide educational value about financial aid processes
+- Demonstrate handling of large, multi-volume document sets
+
+### Source Data
+
+#### Data Collection and Processing
+
+The dataset was created using a LangChain + Prefect pipeline with the following steps:
+
+1. **Source Documents**: Four PDF volumes from the Federal Student Aid Handbook 2025-26:
+   - Volume 3: Applications and Verification Guide
+   - Volume 6: Academic Calendars, Cost of Attendance and Packaging  
+   - Volume 7: The Federal Pell Grant Program
+   - Volume 8: The Direct Loan Program
+
+2. **Processing Pipeline**:
+   - PyPDFDirectoryLoader for PDF text extraction
+   - Metadata enrichment with source tracking
+   - Timestamp recording for provenance
+   - JSON serialization for storage
+
+3. **Quality Assurance**:
+   - Validation of extracted content length
+   - Metadata consistency checks
+   - Source file verification
+
+#### Who are the source data producers?
+
+- **Original Authors**: U.S. Department of Education, Federal Student Aid
+- **Document Type**: Official federal government handbooks and guidance
+- **Publication Year**: 2025-26 processing year
+- **Processing**: Educational demonstration project
+
+### Personal and Sensitive Information
+
+The source documents are public federal guidance materials that do not contain personal information. The dataset includes:
+
+- **Public Policy Information**: Federal student aid regulations and procedures
+- **No Personal Data**: No student records, SSNs, or individual information
+- **No Sensitive Content**: Standard government procedural documentation
+
+## Bias, Risks, and Limitations
+
+### Technical Limitations
+
+- **Processing Year**: Reflects 2025-26 guidelines which may become outdated
+- **Extraction Accuracy**: PDF text extraction may contain formatting artifacts
+- **Scope**: Limited to four handbook volumes, not comprehensive FSA guidance
+- **Language**: English-only content
+
+### Content Considerations
+
+- **Policy Changes**: Federal student aid policies evolve; this represents a snapshot
+- **Interpretation**: Documents reflect official policy but may require expert interpretation
+- **Completeness**: Does not include all FSA guidance documents or updates
+
+### Recommendations
+
+Users should:
+- Verify current regulations when using for research
+- Understand this is educational data, not authoritative guidance
+- Consider potential extraction errors when analyzing content
+- Use official FSA sources for actual student aid decisions
+
+## Educational Value
+
+This dataset demonstrates:
+
+### Document Processing Concepts
+- **LangChain Integration**: Practical use of document loaders
+- **Metadata Management**: Systematic tracking of document provenance
+- **Workflow Orchestration**: Using Prefect for pipeline management
+
+### Real-World Applications
+- **Government Document Processing**: Handling official publications
+- **RAG System Development**: Preparing documents for retrieval systems
+- **Text Analytics**: Analyzing structured government content
