How can we take semi-structured but messy metadata from a repository like CONTENTdm and transform it into rich linked data? Working with metadata from Tulane’s Hogan Jazz Archive Photography Collection, the Linked Jazz Project used Open Refine and Python scripts to tease out proper names, match them with name authority URIs, and specify FOAF relationships between musicians who appear together in photographs. Additional RDF triples were created for any dates associated with the photos, and for those images with place information we employed GeoNames URIs. Historical images and data that were siloed can now interact with other datasets, like Linked Jazz’s rich set of names and personal relationships, and can be visualized [link to come] or otherwise presented on the web in any number of ways. I have not previously presented at a Code4Lib conference.
