@lightweight I'm not aware of any libre discovery layer per se being developed anywhere in the world. Because the difficulty with creating a discovery layer isn't writing the software. It's the data.
If you ever want to convince a librarian to change software, you really do need to understand firstly what the software does, and ideally also everything it integrates with and why, and most importantly all the aspects of the problem that have absolutely nothing to do with software. Because if you go in saying "Look, there's a FOSS alternative, simply use that instead, that'll be cheaper and better because FOSS is always cheaper and better in the long run," then you're not generally going to be very persuasive.
@zeborah I don't have even remotely sufficient ILS experience to go in guns a-blazing, but I definitely think gov't procurement folk broadly have a deeply under-informed sense of comfort with proprietary software because it's so pervasive. The inherent power imbalance (and the lack of ethics in most big corporate vendors) means it will almost always lead to far more cost and pain eventually. The news is stuffed with examples here in Aotearoa (and those are only the ones we hear about).
