A Grammar-Based Framework for Object Dynamics

1992
A grammar-based categorization of practical systems for modeling the dynamic behaviour of objects is presented. A framework based on Augmented Transition Networks is proposed as an ideal modeling tool for such systems, affording both formal analyzability and the functionality needed to model practical systems.

Processing Learning Objects with Attribute Grammars

2009 Ninth IEEE International Conference on Advanced Learning Technologies, 2009
The services provided by learning object repositories are usually enabled by the processing of the metadata documents associated with these learning objects. This paper proposes a way to process these metadata documents, which are usually encoded in XML, through a framework called XLOP.

An Object Grammar for Column-Convex Polyominoes

Annals of Combinatorics, 2004
This articles shows an object grammar decomposition for the classes of column convex and directed column-convex polyominoes. The authors obtain the enumeration of these classes according to the semi-perimeter. In addition to that, they give an explanation of the algebraicity of the generating function for both classes.

Derivations in Object-Oriented Graph Grammars

2004
This work aims to extend the algebraic single-pushout approach to graph transformation to model object-oriented systems structures and computations. Graphs whose sets of nodes and edges are partially ordered are used to model the class hierarchy of an object-oriented system, making the inheritance and overriding relations explicit.

Object-orientation in attribute grammars

1991
Object-orientation is a language design and programming paradigm aiming at better structuring, reusing, and maintaining properties of software. This paradigm has been successfully combined with conventional programming languages, as well as with functional and logic programming languages; it seems obvious that object-orientation has come to stay ...
