Content Schema Evolution in the CoreMedia® Content Application Platform CAP
[chapter]
2002
Lecture Notes in Computer Science
Preserved Fulltext
To control the inevitable evolution of the content schema, the schema should be subject to configuration management together with the actual content. ...
We propose a two-layered approach to content schema evolution consisting of a system level responsible for bookkeeping and integrity issue detection, and a semi-automatic application level responsible ...
The CoreMedia Meta-Model In this section, we describe our meta-model, i.e., our language for expressing a schema and for expressing content. ...

In this paper, we propose a model of schema versions for object-oriented databases called RiBS. At the heart of this model is the concept of the Rich Base Schema (RiBS). ...
As the third element of our model, we give a set of schema update operations, of which semantics are defined so as to preserve all the invariants. ...
Operations We give a set of operations for managing schema versions, which is the last component of the RiBS model. ...

Therefore, a new conceptual framework for product data management systems of configurable products that allows relatively independent evolution of schema and instances is proposed. − The basic concepts ...
Description and management of a large product variety within a single data model is challenging and requires a solid conceptual basis. ...
We model both the schema and the individuals with the same concepts. The basic concepts are object and relation between objects. ...

Its integration into a data model improves the flexibility of the conventional object-oriented data model and allows one to improve the modelling power of objects. ...
The contribution of this paper is twofold: to define an object data model integrating viewpoints in databases and to present a federated database system integrating multiple sources following a local-asextended-view ...
Its main objective is to ensure the autonomy of the component databases, their management and independent handling. ...

Our Distributed Telecommunication Management System (DTMS) uses an object-oriented model to describe the networked Voice Communication System (VCS) to be managed. ...
All other components have either to be VCS-independent or to be generated from the VCS model. ...
modeling process has been introduced, which coherently encapsulates all aspects of the managed VCS (the problem domain) in a conceptual and detailed VCS model applying object-oriented modeling techniques ...

A "raw" building information model schema has been enhanced by user-oriented associations between particular data objects, referred to in this paper as "navigation links." ...
Each link is defined as a new property of a particular concept of the building model schema. Such a link points to a query recipe that can retrieve information about each instance of the concept. ...
A fire protection model or a damage/ deficiency model for example might be such IFC independent domain models. ...

This approach leads to a metamodel made of a collection of model-independent construct types, which we call metaconstructs, used in models to build schemas and corresponding to the tables of the extended ...
