I'm trying to understand the model for querying ATS for RICs (if possible) via the UPA API. The RDM Usage Guide for Java refers to the SymbolList Domain (simple example code also provided as part of UPA) but I'm unclear as to whether we can leverage this capability. The basic use case is for a UPA Java client to query an internal ATS to retrieve all available RICs or merely a subset based on RIC mapping created within ATS. Of course, the alternative is to maintain a static file similar to the dictionary files under /opt/thomsonreuters/SOFTWARE/..
