It automatically discovers the interested configuration information of an industrial process automation system, and provides configuration data, runtime data, alarm/event records, and historical data to clients. It allows clients to search for data items based on process orientated criteria. It tracks clients' search criteria, keeps client selected data items in data groups with multi-part namespace, which data groups can be shared among end users. It calculates the view-count of a data group and the popularity of a data item contained in data groups, which will help the sort of client query results.
