Generate attribution and license messages from RDF metadata
libcredit aims to simplify extracting attribution information for creative works from RDF metadata and formatting at as human-readable credit line in various contexts.
Attribution is retrieved from RDF data by looking for predefined core properties in the graph. The properties include a subset of Dublin Core, Creative Commons, XHTML vocabularies and other site-specific properties (Open Graph, Flickr, etc.).
The process used to extract a credit line from the metadata is documented here (and you are welcome to contribute thoughts there, as well as code to this library): https://github.com/commonsmachinery/credit-metadata-best-practices
Some things described in that process have not yet been implemented, as indicated by open issues: https://github.com/commonsmachinery/libcredit/issues?state=open
