There are substantially complete test cases, a\nsimple example, an ``h5ls`` like utility, and a converter from the\ncurrent Cactus format.\n\nOutdated sketches\n-----------------\n\nThis repository contains a few sketches describing brainstorming results\nin various forms in the subdirectory ``sketches``: -\n``AMR IO Library.md``: Original document -\n``simulations.{gliffy,svg,png}``: Graphical representation -\n``SimulationIO.hpp``: Description as C++ header file -\n``SimulationIO.jl``: Begin of an implementation in Julia\n\nIdeas\n-----\n\n-  Add a UUID to every object\n-  can’t just create UUIDs\n-  probably need to handle set of UUIDs?\n-  Run benchmarks with large datasets\n-  Add parallelism\n-  Add sub-manifolds, sub-tangentspaces, etc.\n-  Allow writing just part of a project, or adding to / modifying a\n   project\n-  idea: whenever creating an HDF5 object, check whether it already\n   exists; if so, check whether it looks as expected\n-  Allow removing parts of a project, deleting it from a file?\n-  Implement (value) equality comparison operators for our objects\n-  Replace H5 SWIG interface with standard Python HDF5 library. To do\n   this, obtain low-level HDF5 ids from Python, and create H5 objects\n   from these.\n-  Allow coordinates that are not fields, but are e.g. uniform, or\n   uniform per dimension\n-  Create ``Data`` class by splitting off from\n   ``DiscreteFieldBlockComponent``\n-  Create ``Value`` class by splitting off from ``ParameterValue``?\n   Unify this with ``Data``?\n-  Range field should use a dataset instead of an attribute\n-  In discrete manifold, distinguish between vertex, cell, and other\n   centerings\n-  Introduce min/max for discrete fields? For scalars only? Keep array\n   for other tensor types, indexed by stored component? How are missing\n   data indicated? nan?\n-  Create DataSpace from vector\n-  Implement SILO writer (for VisIt) (or can this be a SILO wrapper?)\n-  Measure performance of RegionCalculus\n\nSub-Manifolds\n-------------\n\n-  Set of parent manifolds ### Sub-Discretizations\n-  Set of parent discretizations\n-  If directions aligned:\n-  Map directions: int[sum-dim] -\u003e [0..dim-1]\n-  Needs to handle points, lines, planes\n-  If commensurate:\n-  Grid spacing ratio (rational)\n-  Offset (rational)\n\n.. |Build Status| image:: https://travis-ci.org/eschnett/SimulationIO.svg?branch=master\n   :target: https://travis-ci.org/eschnett/SimulationIO\n.. |Coverage Status| image:: https://coveralls.io/repos/eschnett/SimulationIO/badge.svg?branch=master\n   :target: https://coveralls.io/github/eschnett/SimulationIO?branch=master\n.. |codecov.io| image:: https://codecov.io/github/eschnett/SimulationIO/coverage.svg?branch=master\n   :target: https://codecov.io/github/eschnett/SimulationIO?branch=master\n.. |Dependency Status| image:: https://dependencyci.com/github/eschnett/SimulationIO/badge\n   :target: https://dependencyci.com/github/eschnett/SimulationIO\n.. |Zenodo| image:: https://zenodo.org/badge/43850770.svg\n   :target: https://zenodo.org/badge/latestdoi/43850770\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feschnett%2Fsimulationio","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Feschnett%2Fsimulationio","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feschnett%2Fsimulationio/lists"}
