The naming scheme for DRMS datasets is described in the 
[[http://hmi.stanford.edu/development/JSOC_Documents/Drafts/dataset_naming_proposal.pdf|Dataset Naming Proposal]].

There are some deviations and some potentially key parts are not yet implemented.  For instance the "external" record set types are not yet supported.  For DRMS datasets, the @filename feature is not implemented.  But since the @filename construct allows multiple series and possibly multiple catalogs to be included it should be implemented at a higher level.  So for now, only a single record-set is returned by open_records.  ''This could be implemented in drms_open_records collecting any multiple record sets.''

Also for absolute record numbers, a ":" is used rather than the "#".  The prime key ancillary information is apparently not implemented (maybe it is - need to look at code...). The query type of record set is specified by

  [?<where clause>?]

rather than

  [$<query>$>

The format of dataset names presently supported is described in DrmsNames
