Conduit is a library for intuitively describing hierarchical scientific data in C++/C, Fortran, and Python. It is used for coupling between packages in-core, serialization, and I/O tasks. The Conduit Node is the basic abstraction for describing data. The Node supports hierarchical construction.
Here is a simple example of using Conduit in Python.

Here is the output.

Blueprint is a set of higher-level conventions for describing meshes and fields defined on those meshes. The Conduit library can be used to describe in-memory arrays defining a mesh and fields conforming to the Blueprint data model and then writing them to disk. Blueprint can be used to check if a Conduit Node conforms to the Blueprint specification.
Here is a simple example writing a Blueprint uniform mesh in Python.
