This question digresses from main attentio … This question digresses from main attention of this paper. Its more from database point of view. Could we map rdf:bag to a collection in purely relational scheme (eg. varray or nested-table in Oracle. I am not aware how this is done in column stores)? For eg. in the reference table, there can be a row for each paper that is related to a collection of papers. Can this help improve relational scheme, in terms of efficiency of query answer?
Personal thoughts: This would make joins difficult from the collection. But it would reduce number of distinct rows. For eg. separately we can keep publication_author(publication, list of authors). Authors mention that slowly the number of authors contributing to a paper are increasing. rs contributing to a paper are increasing.
