Collaboration and Projects

Hello,

is there a standard way to collaborate using Web Dynpro Projects?

For example, several Components inplement a certain Component Interface (that can not be used outside my project, right?) and are developed by different members of a team.

Can the project (files) be shared and edited simultaneously?

What if the team is small enough to arrange that each Item of the Project is modified by one.

Or is one Project strictly thought to be opened once for modifying? What exactly can be shared between projects (I think of the Jaav Build Path>Projects entries)?

Thanks in advance,

Florian Rehfeld
