As I understand it, ContentProvider - is the data on the global level of the whole device?

The questions:

1) Is it possible to develop and distribute only ContentProvider (no Activity, ie not as a complete application, but only as data)? Does anybody do so? And when? As for the user it will look like? What is the difference between build of ContentProvider and build of normal application?

2) If another developer wants to use my ContentProvider, then how he will be able to access the column names and other data necessary to work with my ContentProvider? I have to give the library?

Thanks
