Secondary data sources such as news articles will be included when they reflect the highest standards of information quality without misinformation or spin. Entries will be short and readable and will contain standardized fields to ensure they reflect the state of knowledge at a given time. The repository will be quality checked weekly by experts in health risk communication. The repository will be updated with new information and old entries deprecated in a timely manner. **Project DOI (Digital Object Identifier)** DOI 10.17605/OSF.IO/B62YZ **Applicable standards** - *Identification of each entry*: DOI (ISO DOI specification ISO 26324) - *Knowledge retrieval*: [HL7 Version 3][1]: Context-Aware Knowledge Retrieval Application (Infobutton), Release 4 - *Metadata*: [Dublin Core][2] - *Portability*: XML encoding - *Vocabulary*: [NLM MeSH][3] - *Web accessibility*: [WCAG 2.1][4] **Data elements for response** *DOI* Each entry should have a Digital Object Identifier (DOI). *Date & disclaimer* Including a date and disclaimer when the entry was created reinforces the rapidly changing nature of risk communications.
