-# Design for netcdf storage format for mcmc traces
+# InferenceData schema specification
+The `InferenceData` schema scheme defines a data structure compatible with [NetCDF](https://www.unidata.ucar.edu/software/netcdf/) with 3 goals in mind, usefulness in the analysis of Bayesian inference results, reproducibility of Bayesian inference analysis and interoperability between different inference backends and programming languages.
 
-/
-All data relating to a mcmc run.
+Currently there are 2 implementations of this design:
+* [ArviZ](https://arviz-devs.github.io/arviz/) in Python which integrates with:
+  - [emcee](https://emcee.readthedocs.io/en/stable/)
+  - [PyMC3](https://docs.pymc.io)
+  - [pyro](https://pyro.ai/)
+      and [numpyro](https://pyro.ai/numpyro/)
+  - [PyStan](https://pystan.readthedocs.io/en/latest/index.html),
+      [CmdStan](https://mc-stan.org/users/interfaces/cmdstan)
+      and [CmdStanPy](https://cmdstanpy.readthedocs.io/en/latest/index.html)
+  - [tensorflow-probability](https://www.tensorflow.org/probability)
+* [ArviZ.jl](https://github.com/sethaxen/ArviZ.jl) in julia which integrates with:
+  - [Turing](https://turing.ml/dev/).
 
-attrs:
-backend: "stan" or "pymc3"
-version: str
-model_name?: str
-comment?: str
-model_version?: str
-timestamp: int
-author?: str
+## Current design
+`InferenceData` stores all quantites relevant in order to fulfill its goals in different groups. Each group, described below, stores a conceptually different quantity generally represented by several multidimensional labeled variables.
 
-/coords
-For each dimension, we store a corresponding variable here, that contains the labels for that dimension.
+Each group should have one entry per variable, with the first two dimensions of each variable should be the sample identifier (`chain`, `draw`). Dimensions must be named and explicit their index values, called coordinates. Coordinates can have repeated identifiers and may not be numerical. Variable names must not share names with dimensions.
 
-/model
-Each backend can store a representation of the model in here. (I guess
-source code for stan, no clue for pymc3 at this point.)
+Moreover, each group contains the following attributes:
+* `created_at`: the date of creation of the group.
+* `inference_library`: the library used to run the inference.
+* `inference_library_version`: version of the inference library used.
 
-/sample_stats
-Statistics computed while sampling, like step size (step_size), depth, diverging, energy (for HMC), log probability (lp), and log likelihood (log_likelihood).
+`InferenceData` data objects contain any combination the groups described below.
 
-/initial_point
-    One point in parameter space for each chain, where that chain started.
-    TODO We could also store that as an attribute to each var in /trace
+#### `posterior`
+Samples from the posterior distribution p(theta|y).
 
-/tuning_trace?
-    Same as /trace, but optional. It contains the trace during tuning. Optional. (only if store_tune=True or so?)
+#### `sample_stats`
+Information and diagnostics about each `posterior` sample, provided by the inference backend. It may vary depending on the algorithm used by the backend (i.e. an affine invariant sampler has no energy associated). The name convention used for `sample_stats` variables is the following:
+* `lp`: unnormalized log probability of the sample
+* `step_size`
+* `step_size_bar`
+* `tune`: boolean variable indicating if the sampler is tuning or sampling
+* `depth`:
+* `tree_size`:
+* `mean_tree_accept`:
+* `diverging`: HMC-NUTS only, boolean variable indicating divergent transitions
+* `energy`: HMC-NUTS only
+* `energy_error`
+* `max_energy_error`
 
-/tuning_advi?
-    Some data about an initialization advi run? History of convergence stats, final sd and mu params? Optional
+#### `observed_data`
+Observed data on which the `posterior` is conditional. It should only contain data which is modeled as a random variable. Each variable should have a counterpart in `posterior_predictive`. The `posterior_predictive` counterpart variable may have a different name.
 
-/divergences
-    Points in parameter space where the leapfrog starts that lead to a divergence (excluding tuning).
-    Does stan have access to that info? We could also just store the accepted point of a divergent trajectory.
+#### `posterior_predictive`
+Posterior predictive samples p(y|y) corresponding to the posterior predictive pdf evaluated at the `observed_data`. Samples should match with `posterior` ones and each variable should have a counterpart in `observed_data`. The `observed_data` counterpart variable may have a different name.
 
-/observed_data
-    All data that is used in observed variables (or the data (or transformed?) data sections in stan.)
+#### `constant_data`
+Model constants, data included in the model which is not modeled as a random variable (i.e. the x in a linear regression). It should be the data used to generate the `posterior` and `posterior_predictive` samples.
 
-/warnings
-    A list of warnings during sampling. Eg low effective_n, divergences....
-    TODO Not sure about the format. Can we somehow share at least part of that between stan/pymc?
-    They mostly produce the same warnings I think.
+#### `prior`
+p(theta)
 
-/prior?
-Samples from the prior distribution. Same shapes as in trace. (except for (sample, chain))
+#### `sample_stats_prior`
 
-/prior_predictive?
-Samples from the prior predictive distribution. Same vars as in /data
+#### `prior_predictive`
 
-/posterior_predictive?
-Samples from the posterior predicitve distribution. Same vars as in /data
+## Planned features
 
-/trace
-TODO We could call this /posterior
+### Sampler parameters
 
-    attrs:
-            The final parameters for the sampler. ie the final mass matrix and step size.
+### Out of sample posterior_predictive samples
+#### `predictions`
+Out of sample posterior predictive samples p(y'|y).
 
-    /trace//var1
-            One entry for each variable. The first two dimensions should always be
-            `(chain, sample)`. I guess the decision whether or not we want to expose a stacked version `draw=('chain', 'sample')`
-            is up to arviz.
-
-            Variable names must not share names with coordinate names.
-
-            attrs:
-                is_free: Whether or not the variable is a free variable for the sampler, or a transformed one
-                domain: One of (“reals”, “pos-reals”, “integers”, “sym-pos-def”, "interval"...)
-                TODO For stuff like sym-pos-def we need to know along which dims it is a matrix.
-                TODO This data could also be stored in /model
-                sym_pos_axis: [dim_idx1, dim_idx2]
-                interval_lower:
-                interval_upper
-                TODO How would this deal with cases where the lower and upper bounds depend on the index?
-
-
-
-TODO: In order to reproduce the run, it may make sense to also store some data on the random state (in numpy, this is a tuple of arrays), as
-well as some version info.  Hopefully just `PyMC3, (3, 4, 1)` or similar works.
+#### `constant_data_predictions`
+Model constants used to get the `predictions` samples. Its variables should have a counterpart in `constant_data`.

 # InferenceData schema specification
 The `InferenceData` schema scheme defines a data structure compatible with [NetCDF](https://www.unidata.ucar.edu/software/netcdf/) with 3 goals in mind, usefulness in the analysis of Bayesian inference results, reproducibility of Bayesian inference analysis and interoperability between different inference backends and programming languages.

 ## Current design
 `InferenceData` stores all quantities relevant in order to fulfill its goals in different groups. Each group, described below, stores a conceptually different quantity generally represented by several multidimensional labeled variables.
 
-Each group should have one entry per variable, with the first two dimensions of each variable should be the sample identifier (`chain`, `draw`). Dimensions must be named and explicit their index values, called coordinates. Coordinates can have repeated identifiers and may not be numerical. Variable names must not share names with dimensions.
+Each group should have one entry per variable. When relevant, the first two dimensions of each variable should be the sample identifier (`chain`, `draw`). For groups like `observed_data` or `constant_data` these two initial dimensions are omitted. Dimensions must be named and specify their index values, called coordinates. Coordinates can have repeated identifiers and may not be numerical. Variable names must not share names with dimensions.

+## Examples
+In order to clarify the definitions above, an example of `InferenceData` generation for a 1D linear regression is available in several programming languages and probabilistic programming frameworks. This particular inference task has been chosen because it is widely well known while still being very useful and it also allows to populate all the fields in the `InferenceData` object.
