| + Web tier using Struts handles collecting user input, dispatches query to GenericQueryHub and displays results. This only knows about generic queries which use simple field names instead of xpaths which could vary according to data format (EML, Darwin, etc.). |
| + |
| + ! GenericQueryHub |
| + Receives a generic query from the webapp. Then for each data source selected to search, it converts the query into an ecogrid query for the appropriate data format using some xref to obtain xpaths for the simple field names. It submits and recieves results for each data source and merges them together returning a single dataset. |
