Digital Identities: Getting to Know the Verifiable Digital Credential Ecosystem

This blog post from NIST’s NCCoE explains and compares credential formats used in verifiable digital credentials, focusing on ISO/IEC 18013 mdoc (mDL) and the W3C Verifiable Credential Data Model. It outlines their differences in data format, primary use cases, standardization bodies, interoperability implications, and where each format may be most appropriate, and notes ongoing work to enable cross-format verification and improved privacy and cross-device flows.
