The URL is constructed automatically as `https://doi.org/{native_id}`.\n- `pmh` — PMH identifier (e.g. `oai:arXiv.org:2301.00001`). URL is looked up from `taxicab_results`.\n- Other namespaces — the identifier as stored in `taxicab_results`. URL is looked up from `taxicab_results`.\n\n**Examples:**\n```sql\n-- Single DOI\nINSERT INTO openalex.taxicab.rescrape_queue (native_id, native_id_namespace)\nVALUES ('10.1038/s41586-023-06600-9', 'doi');\n\n-- Bulk: all DOIs that resolved to linkinghub\nINSERT INTO openalex.taxicab.rescrape_queue (native_id, native_id_namespace)\nSELECT native_id, native_id_namespace\nFROM openalex.taxicab.taxicab_results\nWHERE resolved_url LIKE '%linkinghub%';\n\n-- Bulk: PMH records with errors\nINSERT INTO openalex.taxicab.rescrape_queue (native_id, native_id_namespace)\nSELECT native_id, native_id_namespace\nFROM openalex.taxicab.taxicab_results\nWHERE native_id_namespace = 'pmh' AND error IS NOT NULL;\n```",
