> Currently, a crude mechanism is used to order the start of component types - wait.heartbeat. This is not scalable and does not handle error. 
> Slider needs to support a formal ordering mechanism through dependencies across component type.
> *Proposal*
> At the current state, just ordering start across component types will be sufficient. The dependency can be defined as follows:
> A depends on B
> B depends on C
> A depends on D
> E does not depend on any and non depend on E
> Over all partial order of starting the components is:
> {noformat}
> {D, C, E} --> {B} --> {A} 
> {noformat}
> This will be captured in the metainfo.xml.
