As jazz music evolved alongside sound recording technology and the record industry, so too did the study and cataloging of sound recordings, or discography. From the early discographies of Charles Delaunay through the work of Brian Rust, Tom Lord, and many others, jazz discographers have published thousands upon thousands of pages of highly structured data about jazz records and jazz musicians.
The free database software BRIAN (in honor of Brian Rust), by Steve Albin, allows users to compile their own discographies in the Rust style and easily output this information as HTML. By web-scraping and parsing this data, we can visualize musicians’ performance and recording careers, and better understand the professional relationships of working musicians.

The Linked Jazz project has derived most of the social relationships in its dataset from the transcripts of oral histories given by jazz musicians. One question we began to ask some time ago is: what other jazz historical material in digital form would be a good source of additional relationship data? One answer to that question is digitized photographs, specifically those with good-quality metadata.
Tulane University has a rich collection of historical photographs of jazz musicians living and performing in New Orleans and around the world. The Hogan Jazz Archive Photography Collection and Ralston Crawford Collection of Jazz Photography are two such collections, and we received two tab-delimited text files from Tulane, exported from their CONTENTdm system.
Some numbers: in this set we have 1,787 images, at least 681 unique individuals, and more than 2,700 depictions. Depiction is the FOAF term that we later used as a predicate in our triples from this dataset. One group photograph might depict several individuals, and one individual might be depicted in several photographs. People depicted in the same photograph can be said to “know” each other in some way.
In this post, I’ll describe the process we used to first standardize and reconcile the photograph metadata, and then describe the photographs and the people and relationships depicted using RDF triples. Continue reading Connecting musicians through the photo archive
