-	abstract = {At its core, the Document Object Model (DOM) defines a tree-like           
-                    data structure for representing documents in general and HTML  
-                    documents in particular. It forms the heart of any rendering engine 
-                    of modern web browsers. Formalizing the key concepts of the DOM is 
-                    a pre-requisite for the formal reasoning over client-side JavaScript 
-                    programs as well as for the analysis of security concepts in modern 
-                    web browsers. In this paper, we present a formalization of the core DOM, 
-                    with focus on the node-tree and the operations defined on node-trees, 
-                    in Isabelle/HOL. We use the formalization to verify the functional 
-                    correctness of the most important functions defined in the DOM standard. 
-                    Moreover, our formalization is (1) extensible, i.e., can be extended without 
-                    the need of re-proving already proven properties and (2) executable, i.e., 
-                    we can generate executable code from our specification.},

+                  standard neither defines the concept of web components nor specifies the safety properties that web
+                  components should guarantee. Consequently, the standard also does not discuss how or even if the
+                  methods for modifying the DOM respect component boundaries.
+
+                  In AFP entry, we present a formally verified model of web components and define safety properties
+                  which ensure that different web components can only interact with each other using well-defined
+                  interfaces. Moreover, our verification of the application programming interface (API) of the DOM
+                  revealed numerous invariants that implementations of the DOM API need to preserve to ensure the
+                  integrity of components. },
