Figure 3. Overview of the main relationship types and the implied mapping of point- and range-based selections from the source to the target object. In each cell we show the source object on the left and the target object of the relationship on the right. (A) For order relationships we can directly map array indices between the data objects. In the case of order relationships involving HDF5 Groups we assume alphabetic ordering of elements. (B) In the case of indexes relationships we map selections by retrieving the relevant indices from the source array. (C) For shared encoding and indexes values relationships we support data selection via value-based data mapping, i.e., we map selections by locating all data values in the target object that match at least one of the values we selected in the source object. (D) Shared ascending encoding relationships behave in general similar to shared encoding relationships, however, the additional constraint that values are sorted in ascending order enables us to map range selections directly based on the minimum and maximum value selected in the source (in contrast to the strict equal value matching of shared encoding). (E) User relationships define custom user semantics and do not imply a specific mapping between data elements (not shown).
