PATTERN: NSDL Collection Management (CMgmt)

CAgg CMDP OAgent CR M M-MDP Extra Parent
X X X X CMgmt


How to identify this pattern?

  • Get M with Query: * <http://ns.nsdl.org/api/relationships#metadataFor> <info:fedora/hdl:2200%2F__AGGREGATOR_HANDLE__>
  • Get M-MDP with Query: <info:fedora/hdl:2200%2F__METADATA_HANDLE__> <http://ns.nsdl.org/api/relationships#metadataProvidedBy> <info:fedora/nsdl:3004>
  • If M-MDP query has results, then this pattern has been met. 


Actual Query:

  SELECT t5.o, t5.s, t17.o, t18.s, t18.o
  FROM (t5 JOIN t17 ON t5.s = t17.o)
  JOIN t18 
  ON t17.s = t18.s
  WHERE t5.o = '"Aggregator"' AND t18.o = '<info:fedora/nsdl:3004>'
  LIMIT 2000;

RESULTS: 790


Query with English interpretation's included:  (won't run)

  SELECT t5.o(objectType), t5.s(CAggr), t17.o(CAggr), t18.s(M), t18.o(MDP)
  FROM (t5(objectType_table) JOIN t17(metadataFor_table) ON t5.s(CAggr) = t17.o(CAggr))
  JOIN t18(metadataProvidedBy_table) 
  ON t17.s(M) = t18.s(M)
  WHERE t5.o(objectType) = '"Aggregator"' AND t18.o(MDP) = '<info:fedora/nsdl:3004>'(CMgmt_MDP_handle)
  LIMIT 2000;

Matching Existing Data to New NDR Collection Structure

The following are the objects expected to exist for NDR Collections. There are two types of NDR Collections created for NSDL Library Collection, that is, one NDR Collection for the Library Collection and one NDR Collection each for each Metadata Source. The following identifies how each object for the two collection types will be created or converted from existing objects.

  • Get OAgent with Query: <info:fedora/hdl:2200%2F__AGGREGATOR_HANDLE__> <http://ns.nsdl.org/api/relationships#aggregatorFor> *
  • Get CR with Query: <info:fedora/hdl:2200%2F__AGGREGATOR_HANDLE__> <http://ns.nsdl.org/api/relationships#associatedWith> *
