Welcome to the Digital Data Stories of the Alexandria Archive Institute and Open Context! In this Data Story Short, we contextualize our use of the Title-Author-Source-License (TASL) attribution system that Creative Commons (CC) suggests people use with CC licensed works. As an extension of the Sourcing Series, in this short we summarize and use examples from Data Literacy Program (DLP) materials to contextualize TASL. However, if you'd prefer to get this information from the source, check out Recommended practices for attribution on the CC wiki. This is version 1.0 of this Data Story Short and there have been no major updates to it since publication before PDF upload. However, the live page, where updates will appear first, is available at https://doi.org/10.6078/M7FX77KW.
