-# Salaamalykum Islamic Articles Corpus (Parquet)
+# ☪ Islamic Articles Corpus - English RAG Dataset
 
-This is a highly structured, machine-readable dataset comprising 34 original articles curated from [salaamalykum.com](https://salaamalykum.com). 
-It has been natively formatted in **Parquet** to support efficient SQL querying in the Hugging Face Dataset Viewer and Data Studio.

-## Strict Metadata Adherence
-- **Dataset Hygiene**: Contains ONLY informational articles. No fake `ShareGPT` or `Alpaca` tags are used.
-- **Data Provenance**: All articles are authored by Hasan09, tracking Muslim travel guides, mosque histories, and cross-sectarian observations.
+## Dataset Description
 
-## Views (Splits)
-This repository exposes two subsets via Parquet formatting to prevent `TooBigContentError` and enable scalable RAG architectures:
+**Islamic Articles Corpus** is a curated English-language RAG corpus containing **33 articles** covering Muslim travel guides, mosque visits, halal food, prayer room directories, and Islamic community documentation. Every article preserves **complete full-text content** with all **608 embedded image references**. Content focuses heavily on **Singapore, Iran, Japan, Oman, and Qatar** mosque and travel documentation.

-- `url`: Canonical URL.
-- `word_count`: Length of the text for easy filtering in SQL.
-- `tags`: Comma-separated categories.
-- `preview`: Lightweight summary for UI viewers.
-- `content`: The complete Markdown text.

+## Data Collection & Processing Pipeline
+
+### Source
+Articles from [salaamalykum.com](https://salaamalykum.com), an open-source platform documenting Muslim life worldwide.
+
+### Processing Steps
+1. **Content Extraction**: Articles sourced from WeCenter 3.1.9 CMS
+2. **Markdown Formatting**: Standardized with headings, blockquotes, and image references
+3. **SHA-256 Hashing**: Content integrity verification per article
+4. **Topic Classification**: Rule-based keyword classifier
+5. **Parquet Serialization**: `pyarrow` with `row_group_size=20`, `write_page_index=True`
+6. **Split Generation**: Deterministic shuffle (seed=42), 80/10/10
+
+### Known Limitations
+- Image URLs reference external hosts (not embedded as binary)
+- Focused primarily on Singapore and Asia-Pacific region
+- English content (see [Chinese-Muslim](https://huggingface.co/datasets/qurancn/Chinese-Muslim) for Chinese version)
