A) DCP1 vs DCP2
    * DCP1 hard to maintain, DCP2 things can be changed.
    
    Used in two places:
       Eclipse Help Search (low priority)
       JBoss Central (higher priority)
       
    Options:
       1) keep dcp1 alive for 3+ years
       2) make dcp2 output dcp1 format for 3+ years 
           output  has changed because of upgrade of elasticsearch.
           limited resources since Lukas Vlcek.  left, dcp in maintenance mode so far.
           
           Idea: could we have a "transforming" proxy that converts dcp2 json  to dcp1 json.
           should be trivial.
           
       3) we "fake" dcp1 by having a static page somewhere that gets updated once in a while.
       
       Suggest: 
           we just make devstudio 9.1 use a static output - do changes in devstudio 10.
        
B) EAP 7 quickstarts
      multiversion have been downprioritized:
                      not on Ray and Harry's radar.
      
      Paul - look into how hard it can be done ? let us known Wednesday lunch time.

Paul's Observations:

Realistically we will not have multi-version support in JBD and thus DCP1 data. Also, we will need to update the JBD EAP Quickstarts to v7 (and thus the DCP1 data). Therefore, I don't see an outcome where JBDS 9 isn't showing only v7 quickstarts for EAP.

Fred's Idea: Cache the results for EAP 6 and redirect the JBDS 9 code to get that. Potentially, we could cache the EAP 6 results prior to the DCP1 data being changed to have EAP 7 quickstarts. After this change, take another snapshot of the data. Merging these two snapshots results in a multi-version snapshot to provide to JBDS 9.

Only give JBDS 9 multi-version support if JBDS 10 also gets this support. Otherwise a regression is created.

> ~1 year ago we made Central use DCP for querying the quickstart list to let users start easily with the examples/quickstrats.
> In the context of EAP 7 coming out there are new quickstarts.
> In a perfect world the following have happend:
> EAP 7 Quickstarts added to DCP
> Central in both devstudio 9 and 10 can see both EAP 6 and EAP 7 quickstarts
> What seem to have happened instead is:
> if EAP 7 quickstarts are added to DCP EAP 6 quickstarts are no longer available
> DCP has changed its format/approach and not sure what the impact of this is
>  (can devstudio 9 still work ? must devstudio 10 change ? will we ever have multiple version support ?)
> This bug is to gather the facts and figure out what we do about them.
