 ### Data Splits
 The dataset is provided as a single Parquet file without predefined splits.
+Original JSON files are available at `original_json_data/` in this repository,
+as is the script (`scripts/export_script.py`) that was used to convert the
+individual JSON files to the single `.parquet` file.
 
 ## Dataset Creation
 ### Curation Rationale
 The dataset was created to provide a comprehensive and publicly accessible record of ISAF's kill-capture missions in Afghanistan, as reported in their press releases. The motivation was to enable scholars, legal teams, and others to analyze and understand the nature and extent of these operations, as the original ISAF website no longer exists in the same form. The dataset serves as an important historical artifact for Afghan history and provides a means to reverse-engineer the minimum numbers of people killed and captured by ISAF during the specified period.

+### Initial Data Collection and Normalization
 The initial data collection involved manually copying the text of press releases from the ISAF website (http://www.isaf.nato.int/article/isaf-releases/) into Tinderbox software. The press releases were collected from December 1, 2009, to February 21, 2013, covering a period of over 21 months. All available press releases during this period were included in the dataset.
 
 The collected press releases were then processed to split them into individual incident reports. If a press release mentioned multiple incidents, they were separated into distinct entries. The text of the press releases was not modified and remains in its original form.
