The NC code signifies the available meta-data objects. The presence of each number signifies the presence of a specific meta-data object. The numerical codes for each object are: 1 co–authorship, 2 abstract, 3 title, 4 cited references, 5 journal, 7 research address, 8 author keywords, 9 indexer keywords (6 journal Category is not shown)
