[kepler-dev] Naming Conventions for Actors?

Hi Glen,
There are a couple of different issues here, I can address the Ptolemy
issues.  Kepler uses Ptolemy, so some of the actors are Ptolemy

Ptolemy has a style guide at
that says that Java classes and variables should use CamelCase names.
We don't abbreviate words, so the words should be complete words.

Parameters can have a Java name and a separate display name that can
have spaces.  

Kepler has similar, though slightly different styles, see 

I'm not that sure about the style of the Kepler Guide.

In the Ptolemy design docs, I usually stick with the Java CamelCase
name, but that is because I'm a Java programmer, so I write for
other Java programmers.  The Kepler docs could easily use a different



    As a new person, I often feel embarrassed about asking questions that  
    may or may not be "tribal knowledge." Sometimes I only need directed  
    to a document or site that I may not be aware of to get the answers  
    that I need.
    Some of my more "nit-picky" notes that I have found, with fresh eyes  
    to the project, include the confusion with the "SummaryStatistics"  
    actor [Notice no space].
    Almost all other actors in the Guide followed a convention that  
    included spaces, and capitalized the first letter of every word. When  
    looking at a nightly build, I see the actors in Components -> Data  
    Input -> Local Input, for example, have a mix of conventions. Most are  
    of the convention mentioned, like "Binary File Reader", "Current  
    Time," and "Directory Listing." Others omit the spaces, similar to  
    some Object Oriented naming conventions (which is obviously  
    appropriate) like "ClimateChangeFileProcessor" and  
    I am assuming from the sheer number of actors of the first convention,  
    the standard includes spaces and that external actors like  
    "ClimateChangeFileProcessor" and "ClimateFileProcessor" all came from  
    the same source that did not follow the convention. Am I incorrect?
    Where can I find naming conventions and programming guidelines? They  
    are obviously important because, as an end-user, there is a different  
    searching behavior (and returned results) depending upon how an actor  
    is named.
    Again, thank you to everyone thus far that has been extremely helpful.
    Warmest Regards,
