VaeQL is our proprietary navigation and query language for specifying exactly what content you want to display, use, or operate on. The VaeQL syntax is based on XPath 1.0, a standard language for querying structured data. If you already know XPath, you'll pick this up quickly. If not, we'll get you up to speed.
VaeQL adds some helpful features to the XPath 1.0 standard, such as ability to easily locate an individual item by its ID, predicate functions that are aware of the environment, support for associations and reverse associations, and the ability to extend the syntax with additional functions.
