The explainer talks about highlevel goals and not use-cases

[kenchris]

In response to w3ctag/design-reviews#390

Could you flesh out the goals a bit further in the case of exact use-cases?

[pwnall]

@oyiptong will respond to this.

@kenchris the goals subsection contains 3 use-cases.

I'll quote:

Some example use cases we would like to address:                                                                                                                                                                                                                                                                                                                                            
* A simple "single file" editor. Open a file, edit it, save the changes back to                                                                                                               
  the same file or other files. Also possible integration with a "file-type                                                                                                                   
  handler" kind of API. Things like (rich) text editors, photo editors, etc.                                                                                                                  
                                                                                                                                                                                              
* Multi-File editors. Things like IDEs, CAD style applications, the kind of apps                                                                                                              
  where you work on a project consisting of multiple files, usually together in                                                                                                               
  the same directory.                                                                                                                                                                         
                                                                                                                                                                                              
* Apps that want to work with "libraries" of certain types of files. I.e. photo                                                                                                               
  managers, music managers/media players, or even drawing/publishing apps that                                                                                                                
  want access to the raw font files for all fonts on the system.   

Would you like more concrete examples? Or perhaps a more fleshed out explanation on how the APIs would apply to those use-cases?

[kenchris]

These are not written as use-cases. "Open a file, edit it, save the changes back to
the same file or other files" is a use-case, "a single file editor" is not.

Something like:

• Open files from the users file system
• Modify opened files and save them back to the file system
• Have multiple web apps access the same file at the same time
• be able to access opened files in future browser sections

I guess you get the hang of it :-)

[oyiptong]

Thanks for the quick feedback! I'll write down the use-cases in the format you suggested.
