Collective Metrics

Collective Metrics is an open source project that defines standard metrics for online safety, trust, privacy and security, and publishes dashboards built from public data (transparency reports, DSA statements of reasons, regulatory filings). The idea is that everyone measures the same things the same way, so a "prevalence" number from one platform can be compared to another.

It's useful two ways: as a reference for which metrics to report, and as a source of comparative data when you're benchmarking your own numbers. The metric definitions and pipeline code are open.
