SP Version Information

Dears,

I am new to Java stack.

Recently I installed PI 7.1,By system information I get to know that for one component its version is

1000.7.10.4.0.20071122205900

so I want to know what is the version of this component.As I am understanding 7.10 is system version in this.

But not getting meaning of other numbers.

Please suggest.
