? Structure attributes
Help on Structure attributes :
The Structure attributes indicator reveals how uniformly attributes are dispatched. Besides the standard amount of attributes per element (with min, max, mean and standard deviation) is the disorder ratio.
The disorder ratio attempts to show if attributes are listed in the same order or not wrt element instances. That's of course an average, because each element may have any amount of associated attributes. According to the W3C Xml norm, there is no special ordering between attributes, it is simply a good habit to have attributes always following the same order. Close this one
Help on Min Attributes per element :
This is the minimum attributes amount over all elements in the Xml stream. If one element does not have attribute, then this is 0. Close this one
Help on Max Attributes per element :
This is the maximum attributes amount over all elements in the Xml stream.
If this is low, say below 2, thats because the Xml stream is much "vertical", uses element hierarchies instead of attributes. This may be ok, but with a serious overhead on stream size. Close this one
Help on Mean Attributes per element :
This is the average attributes amount over all elements in the Xml stream.
If this is low, say below 2, thats because the Xml stream is much "vertical", uses element hierarchies instead of attributes. This may be ok, but with a serious overhead on stream size. Close this one
Help on Standard Deviation Attributes per element :
This indicator shows how is distributed the Xml structure wrt the attribute amounts per element.
This is 0.00 of there is no attribute at all in the Xml stream. If the standard deviation is low, say below 1, it means that attributes are uniformly dispatched between attributes.
NB: the standard deviation is mathematically speaking the 2nd order moment of the name size distribution. Close this one
Help on Attributes disorder ratio :
This indicator, expressed in percentage, shows how are unordered the attributes.
The higher, the more unordered. That is 0.00 if there is no attribute at all in the Xml stream.
