Hi Afsheen,
Thanks so much for writing in about this! This plugin was originally created by a GBH developer as part of a previous grant to provide more tools for the usage of PBCore, but unfortunately that grant has now ended, and the developer who did this work for us has since taken a new position. As a result, we don't have a concrete timeline for when the plugin may be back up to date. However, we'd really like to start a conversation with Lyrasis to see what kind of support and funding it would take to get the plugin compatible with the new version of ASpace, and the more support we can get to show that there's a demand for the work, the likelier it is that we can make a case for it.
We'd love to hear from anyone else who has interest in this as well -- if you think there's a use case for this at your institution, please let us know!
Best,
Rebecca Fraimow
