1.4 Best Practices for Attribution (TASL)
LOs: [1d]
Open licensing makes reuse possible, but lawful reuse also depends on giving proper credit. Attribution matters because every Creative Commons license requires it, and clear attribution helps other people find the original work, identify the creator, and understand the license terms.
Building on 1.2 The CC License Elements and the Six Licenses, this subunit focuses on the BY (Attribution) element that appears in every CC license. It also connects to 1.3 CC0 and the Public Domain, where you saw that CC0 does not require attribution even though giving credit remains good practice. Here, you will learn a practical method for crediting CC-licensed works correctly.
The source presents TASL, a simple attribution model. Title means the name of the work, if one was given. Author means the creator's requested form of credit, which may be a real name, a pseudonym, or an organization. Source means a link to where the work can be found, ideally its original location. License means the specific Creative Commons license, linked to the license deed, such as CC BY 4.0.
The source also explains what strong attribution looks like in practice. A concrete example is the photo "Creative Commons 10th Birthday Celebration San Francisco" by Timothy Vollmer. The source identifies the title, the creator, and the fact that the work is licensed under CC BY 4.0, with the title linked to the source and the license name linked to the license deed. This example shows that TASL is not only a memory aid; it is a usable structure for real reuse situations.
The source adds one more important point: while every CC license requires attribution, CC0 does not, although crediting the source is still good practice. That distinction helps you apply TASL correctly without confusing legal requirements and recommended practice. As you read, consider how each part of TASL helps a later user verify both where a work came from and what they are allowed to do with it.
