Worked on the AdobeDocs/adobe-io-events repository to enhance documentation for Marketo notification and user audit data stream setup guides. Focused on improving the clarity and accuracy of the 'source' field by updating its allowed values from a generic URL to a specific URN format, such as 'urn:mlm', aligning the documentation with the underlying data model. Utilized Markdown to deliver these targeted improvements, ensuring that developer guidance is both precise and actionable. This documentation update improved data quality, event context clarity, and traceability across event streams, while also reducing potential support overhead by providing clearer configuration instructions for developers.
