What does sharing of all resources means?

Shared source is a software licensing concept that is more open than the proprietary approach to licensing but more restricted than the open source model. Under a shared source program license, authorized parties are granted full or partial access to source code. Typically, those granted access can view source code but cannot alter it for any commercial purpose. Some shared source programs allow only viewing of code; others allow non-commercial alteration and/or redistribution. Hope this helps!
