Field	Content
name	VisaAdvisor Country Hub
description	VisaAdvisor Country Hub is an open, versioned travel-intelligence project that separates source-backed facts from editorial planning judgments. The public foundation pre-release links records to dated evidence, publishes its methodology and limitations, and provides reusable CSV and JSON files under CC BY 4.0 for the original compilation, structure and documentation. Developed from Brazil for global and Arabic-speaking travellers, researchers and publishers, its current scope includes 12 South America planning profiles and a public field-evidence model. It is a foundation release, not a complete global database. DOI: https://doi.org/10.5281/zenodo.21858354
