51Degrees API Documentation  4.4


Aspect properties extend element properties to add metadata relevant to aspect engines.

As aspect engines consume external data from either a data file or cloud service, extra metadata is included to indicate where the property is available.

See the Specification for more technical details.

Data tier

The data tier of a property describes which product tiers the property is available in. For example, an aspect engine could consume both a free and enterprise data file. Please be aware that certain properties may not be available in the free data file..
