I have three PLaneT packages that together implement a knowledge-based simulation capability. I did this because each of the packages is useful in its own right. The science collection provides the basic mathematical framework - I use it separately in many analysis applications. The simulation collection provides a hybrid discrete-event and continuous simulation engine. The inference collection provides a hybrid forward-chaining and backward-chaining inference engine. Although they were developed together and I often use them together, they are separate collections. As such, they are documented separately and the examples in each are specific to that collection. Now, I have written a good example knowledge-based simulation that cuts across all of them and I am planning on developing documentation on how to use the packages together. Should I package this up as a PLaneT package itself although it doesn't add any new functionality? Is there a better way to distribute something like this - more like an application note than an applicaton? It seems to be the only way to do it in the current framework. [It will be in the Schematics repository on Sourceforge. But I pretty much just use that as my development repository.] Also, when using the simulation collection one (almost) always uses the random distributions from the science collection. In my development branch, I have now just re-exported the random distributions in the science collection from the simulation collection. Thus, I only have the one PLaneT require in user code instead of two. [I don't want to move the random distributions to the simulation collection because they really are part of the mathematical framework and logically belong in the science collection.] Is this going to bite me later if someone needs other elements of the science collection and does a separate require - i.e., will the names conflict even though they are (ultimately) the same objects?
