Is this project still under development?

I'm not super into the OpenPP name. How about calling this Probabilistic.jl?

Since model representation, inference and learning are going to be split following the ML paradigm (with which I personally agree), one question is where the reduced factor graph will be generated. I imagine that the code for the original factor graph will be hosted in OpenPP as part of the model specification. On the other hand, the queries related to inference will be coded in external packages (MCMC or GLM for example). The rising question is how the external packages will interact with OpenPP to deduce the reduced factor graph, as described in the inference framework of the proposal.

I can see two options; one would be that each external package will provide the implementation for the generation of the reduced factor graph, alongside with its inference code. The second option is to make sure that OpenPP is equipped with generic algorithms for the creation of the reduced factor graph (this falls within the scope of graphical model algorithms that are meant to have separate semantics from inference) and with an accompanying query API, which will allow external packages to define their queries using a universal framework. I find the latter approach more reasonable.

I was thinking that, following the proposal and the natural order of things, the first step after choosing the package name is to decide how the model specification will be entered by the user. That's the first component of the API and framework. Will it be an expression, which will then be parsed to a graph internally?

As described in https://discourse.julialang.org/t/ann-plans-for-removing-packages-that-do-not-yet-support-1-0-from-the-general-registry/ we are planning on removing packages that do not support 1.0 from the General registry. This package has been detected to not support 1.0 and is thus slated to be removed. The removal of packages from the registry will happen approximately a month after this issue is open.

To transition to the new Pkg system using Project.toml, see https://github.com/JuliaRegistries/Registrator.jl#transitioning-from-require-to-projecttoml.
To then tag a new version of the package, see https://github.com/JuliaRegistries/Registrator.jl#via-the-github-app.

If you believe this package has erroneously been detected as not supporting 1.0 or have any other questions, don't hesitate to discuss it here or in the thread linked at the top of this post.
