Head vs. Dependent Marking

Is anyone familiar with the concept of "head-marking" vs.
"dependent-marking" languages?

As I understand it, Indo-European languages tend to be
"dependent-marking," which means that they
1. mark the depedent noun in a noun-genitive relationship
2. mark the arguments of a verb to indicate their argument role

Whereas some other languages (Hebrew?) are "head-marking," which
means that they
1. mark the head noun ("construct state") in a noun-genitive
relationship
2. mark the verb to indicate what its arguments are (via agreement
markers?)

Is this an accurate summary of what's going on?  Can anyone add
anything to this?
