Mar 24, 2009 · We establish a sound and complete set of inference rules for this expressive fragment of XML keys, and encode these rules in an algorithm that ...

We analyse the impact of extending this fragment by structural keys that uniquely identify XML elements independently of any data. We establish a sound and ...

In particular, suitable notions of keys will enhance XML's capabilities of modeling, managing and processing native XML data. However, the dierent ways of ...

However, the different ways of accessing and comparing XML elements make it challenging to balance expressiveness and tractability. We investigate XML keys ...

Constraints are important for a variety of XML recommendations and applications. Consequently, there are numerous opportunities for advancing the treatment ...

We analyse the impact of extending this fragment by structural keys that uniquely identify XML elements independently of any data. We establish a sound and ...

This page shows the traffic from major research institutions for Expressive, yet tractable XML keys on Sciweavers sorted by most recent.

In comparison to previous work, this new fragment of XML keys provides designers with an enhanced ability to capture properties of XML data that are significant ...

Evidently, the expressiveness (but also the tractability) of a fragment of XML keys will depend on the query language used to navigate between nodes in trees.

Keys for XML data trees can uniquely identify nodes based on the data values on some of their subnodes, either in the entire tree or relatively to some ...
