ESCDF - Electronic Structure Common Data Format
Data representation standards for large data sets (wave-functions, expansion coefficients, electron density, local density of states, etc.). Detailed description to come. It is based on NetCDF4, which uses HDF5. The standards defined should be both readable and writable by both.
Tools for the simpler reading and writing of these representations are coded in the library libbigio. It is under development. In particular, the working library does not do parallel R/W yet. See ESL Activities.
Both the standards and the tools originate from a first standardisation effort done in the European Nanoquanta Network of Excellence, that evolved into ETSF-IO.
