The actual JSON schemas, Edition 1.0 standard PDF, and white paper are free but require an Open Group web account; schemas were not downloaded because they are behind a login gate. | ## Conversion method - PDFs and public HTML pages were converted to Markdown using **Firecrawl v2** (`https://api.firecrawl.dev/v2/scrape`) with the project API key. - `HydroWASTE_v10.zip` was AWS-WAF-protected; it was retrieved by allowing the browser to solve the WAF challenge, then moving the downloaded file from the browser’s Downloads folder into `NEFDB/datasets/waste_water/`. ## Overall result - **100 % of priority URLs downloaded or explained.** - All six gaps now have at least one usable open dataset or regulator/company report. - Remaining limitations: (a) post-2014 HFC import data, (b) Nigeria-specific steel / fertiliser process factors, (c) Open Footprint JSON schemas and standard PDF are gated by a free account.
