ASF GitHub Bot commented on JENA-1107: -------------------------------------- GitHub user afs opened a pull request: https://github.com/apache/jena/pull/115 JENA-1107 : Improve Tuple. Improvements: * Tuple as Interface * Implementation focused on being "Tuples", not only for TDB (it's historical origin). * Less space for small tuples. * Avoid array overheads for small tuples. * TupleMap uses more consistent naming than ColumnMap. * TupleMap can be used for index mapping, array mapping, not use Tuple mapping.

Triple elements > are accessed by name ({{getSubject}} etc), not index. SPO is just one > possible order in which to think about triples but it has no special status. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
