Hippo is a piece of software aimed at making FAIR (Findable, Attributable, Interoperable, and Reuseable) data access easier. Through the use of the very flexible MongoDB for true metadata storage and MinIO as a data storage backend, hippo provides metadata-driven access to reusable products.
Hippo is under development for the Advanced Simons Observatory, an NSF-funded telescope project that aims to study, among other things, the Cosmic Microwave Background. Throughout the project, many pieces of data will be produced: things like images, arrays, small databases, etc. Storing and sharing these within the collaboration, and to the public, is a huge challenge; it's easy enough to put them all in a big folder somewhere, but without associated metadata you will never be able to find what you're looking for.
Enter hippo! Hippo allows you to upload data products and access them both manually and programatically through a metadata-driven interaction.
