OpenSpace Considerations
When appending OpenSpace layers, the following rules apply:
1) If the source layer has a column with a formula that differs from the formula of
the same column in the target layer, the target layer's formula overwrites the
source's layer's formula and is automatically applied to the entire layer.
2) If the target layer is schema 310-330, its classification overwrites the source
layer's classification(s). If the target layer is schema 400+, all classifications are
preserved in both the target layer and source layer. The target layer's active and
default classifications are adopted in the resulting layer.
3) If the source layer and target layer have identically named Extended Attribute
Sets that contain different attributes and join rules, the attribute sets are
automatically unlinked from the source layer when appending occurs. The target
layer maintains the link for its Extended Attribute Sets.
4) If the source layer has a different label structure than the target layer, the target
layer's formula is adopted and automatically applied to the entire layer.
Replace
This import method is used to replace, or overwrite, an existing GIS layer with a new
layer. The new layer must be of the same geometry type as the existing layer, and
attribute columns must have an exact name match in order to append to each other.
In addition, like-named attributes in the incoming layer must be of the same type
family in order to append. The importer will be as tolerant as possible within a type
family, allowing data to convert or widen. For example, a 100-character string
column in the source layer will widen to match a 200-character string in the target
layer, and vice versa.
The following list shows which attributes are compatible, and the direction of
compatibility:
