Automatic Techniques for Data Model Translation
Distributed information systems deal with different data models and transformations between them are required. In this paper, we present a framework for the automatic translation of data between heterogeneous representations. Translations operate over formal representations of schemes and data and rely on a uniform description of models that we call metamodel. Complex translations of schemes an...
متن کاملComputationally secure multiple secret sharing: models, schemes, and formal security analysis
A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. Up to now, existing MSSs either require too long shares for participants to be perfect secur...
متن کاملTowards Synchronizing Models with Evolving Metamodels
Metamodel evolution poses a threat to the applicability of Model-Driven Development to large scale projects. The problem is caused by incompatibilities between metamodel revisions. These render models that conform to the older version of the metamodel non-conformant to the newer version. An approach to addressing this problem is co-evolution of models with their respective metamodels. In this p...
متن کاملAn Approach to Heterogeneous Data Translation based on XML Conversion
In this paper, we illustrate a preliminary approach to the translation of Web data between heterogeneous formats. This work fits into a larger project whose aim is the development of a tool for the management of data described according to a large variety of formats used on the Web and the (semi)automatic translation of schemes and instances from one model to another. Data translations operate ...
متن کاملUsing a Program Transformation Engine to Infer Types in a Metamodel Recovery System
Domain-Specific Modeling (DSM) allows domain experts to concentrate on the essential characteristics of a problem space without being overwhelmed by the complexities that may occur in the solution space. DSM is focused on the creation of a metamodel for a specific domain, from which instances pertaining to specific configurations of that domain can be constructed. However, as the metamodel unde...
