MassDOT and image reuse

I recently added a link on my blogroll: "Commonwealth Conversations", the official transportation blog of MassDOT. As well as highway projects, MassDOT is in charge of projects like South Coast Rail that involve new passenger rail or transit service, so much of the content is about such projects. They also post about MBTA projects.

One such post is today's, which announces approvals for the new Assembly Square station on the Orange Line and the rebuild of Orient Heights on the Blue Line. I am very glad to see both projects advancing.

There is one image in the post: a shot of the front of Orient Heights station. I recognized it immediately, because I just moved it to Wikimedia Commons yesterday.

It is originally from Flickr, posted here. I moved it to Wikimedia Commons with using a web interface because the photo is available under a free-use Creative Commons licence. This means that it is eligible to be used freely on Wikipedia and other sites as long as the terms of the licence are met.

In this case, it's a CC-BY-SA 2.0 licence. The BY term means that attribution is required: free reuse is only allowed if the author is properly credited. The SA term requires sharealike: any modification of the file must be licenced by the reuser under a similar free licence.

Use on Wikipedia meets those terms: clicking on the file takes you to a description page that credits the author, and Wikipedia itself is released under a free Creative Commons licence.

But MassDOT's use does not meet the terms. Both the Flickr version and the Wikimedia Commons reuse require attribution and sharealike. MassDOT's blog does not mention that the photograph was taken by Scott Lapierre, or provide a link to the Flickr or Wikimedia page, and it fails to release the resized version under a free licence.It's an easy and very common mistake to make, and one I've made myself in the past; I only personally became responsible about it after I started uploading files to Commons. Hopefully MassDOT, as a state agency, can set an example with correct attribution of free-use photos.
