RESTful HDF5 Interface Specification 0.1

RESTful HDF5 Interface Specification 0.1 is a document that specifies a REST (REpresentational State Transfer) interface for HDF5 data stores. It describes HDF5 resources, URIs, and resource representations, and shows a simple example of how to use this interface to populate an HDF5 store.

Please note that this is version 0.1 of this specification. Resource granularity and representations are based on our own experiments and a limited understanding of "real" applications.

We invite you to share your comments/thoughts regarding this, via the HDF-Forum or you can reply directly to the author. We would like to know how you would use an HDF5/REST interface with your data. If you would consider participating in a trial, please let us know that, as well.
