As metadata providers increase in number and diversity, and additional contexts for metadata use are identified, issues of trust, provenance and identity gain in relevance. Use of a public-key infrastructure (PKI) is discussed for digital signature of metadata records, providing evidence of the identity of the signer and the authenticity of the information within the record.Two methods are suggested; firstly, the W3C XML-Signature, and secondly, identification of a minimal set of metadata elements enabling signature verification across various character sets formats using the OpenPGP standard. Possible strategies for handling annotation within this infrastructure are suggested. Finally, some use cases are briefly discussed.
