Combining Ontology-enriched Domain-Specific Languages
2009
ACM/IEEE International Conference on Model Driven Engineering Languages and Systems
Preserved Fulltext
Hence the question arises: How can we combine DSLs and in addition integrate their semantics and constraints? ...
Then we give an answer of how to combine these ontology-enriched DSLs and present a solution of integrating constraints and semantics of several languages. ...
These constraints are not merged because in our approach only the ones with equal class expressions are merged. ...

In combination with a Finite Element model for elasto-plastic objects and a geometric constraint approach, con- straint sets are applied to simulate the merging and breaking of conforming and non-conforming ...
Using constraint sets, data structure updates in case of topology changes are simple and efficient. ...
Only a few authors have dealt with the merging of meshes in dynamic simulations. [BWHT07] presents a merging approach in the context of visco-plastic flow. ...

For every pair of matching concepts, we have two choices: merge them into one integrated concept or keep them as separate concepts. ...

With such an expressive language, we are able to make use of not only query containment constraints, but also query equivalence constraints and integrity constraints (ICs) shipped with the input schemas ...

Concept Extraction: The first step of our integration method is to recast each source schema, with its constraints and nesting, into a higher-level concept hierarchy (with no constraints or nesting). ...
For example, the user can enforce a pair of matching concepts to be always merged or never merged (e.g., "merge dept with org", or "do not merge dept with address"). ...

In both cases, we consider the incorporation of entailment-based and consistency-based integrity constraints. ...
Properties of these operators are investigated, primarily by comparing their properties with postulates that have been identified previously in the literature. ...
Postulates (IC1)-(IC6), with tautologous integrity constraints, correspond to basic merging, without integrity constraints, in [11] . ...

In this paper, we present a novel approach for merging multiple relational data sources related by a collection of mapping constraints in the form of P2P style tuple-generating dependencies (tgds). ...
Classical data integration systems rely on a mediated schema created by human experts through an intensive design process. ...
We first state the problem of n-ary schema merging in Section 3.1, where the inter-schema mapping constraints and source integrity constraints are unified. ...

This approach then accords with one's intuitions as to what a "merge" operator should do. The second approach is more akin to a generalised belief revision operator. ...
