Overview of Tree Formats
Abbreviations of tree formats are described below.
ea | Element and attributes (without hierarchical information). |
fh | TreeFH (Full Hierarchy Tree): creates a full, level-based hierarchy. See article TreeFH Transform. |
fhw | TreeFH with weights. |
fhwa | TreeFH with weights and attributes. |
lew | TreeLE (Tree Level and Element): level element with weights. See article TreeLE Transform. |
lewta | TreeLE with weights, type (string, numeric, consolidated), and attributes. |
ncw | TreeNC: N stands for base element and C stands for consolidated element. Numeric-consolidated type with weights. See TreeNC Transform. |
ncwa | TreeNC with weights and attributes. |
none | Does not build a tree, but delivers the underlying tabular raw data of the source. This format has the fastest response time, but the data might be incomplete or ordered incorrectly. "None" is the default format, if no tree format is specified. |
pc |
TreePC (Parent-Child): creates a tabular representation of parent-child relationships. It only contains 2 columns: parent and child. See article TreePC Transform. |
pcw | TreePC with weights. |
pcwa | TreePC with weights and attributes. |
pcwat | TreePC with weights, attributes, and type (string, numeric, consolidated). |
When referencing a tree-based source and no tree format is set or format is "NONE", then the "native" format of the source is used.
The "native" format of the source is "FH" for all tree-based extracts/ transform types, except the following three transforms:
- For TreeNC it is "NCWA"
- For TreePC it is "PCWA"
- For TreeLE it is "LEWTA".
In all these cases the ordering of the elements may be different as when the according tree format is set.
