Data Model Repository 426 views
(The data model repository is currently still in the data filling phase)
The repository of data models contains data models of basic registers, records and key information solutions of public administration. It allows their structures and metadata to be stored centrally and in a uniform manner. It provides existing and potential users with precise information on which data is already collected within the framework of public administration and therefore does not need to be defined anew. The repository provides:
• Standardized conceptual and logical data models.
• Standardized and comprehensive description of classes, entities, relations, attributes, etc.
• A uniform and broad set of metadata, which enables a clear and unambiguous definition of the content of databases.
• Ownership information.
• Versioning and change control.
• Link to reference data (code books) and the Central Vocabulary.
• Relationships (mappings) between individual basic registers and their data elements.
Core data models are also included in the Data Model Repository. These are reusable and extensible data models that capture the fundamental characteristics of entities in a context-neutral way. Public administration bodies can use and expand them in the following ways:
• Development of new information solutions: core data models can be used as a default starting point for creating conceptual and logical data models of newly developed information solutions. Such an example can be e.g. common, universal business processes, such as the implementation of the Administrative Procedure Act.
• Data exchange between information solutions: Core data models can form the basis of context-specific data models for data exchange between existing information solutions.
• Data integration: Core data models can be used to integrate data coming from different heterogeneous sources.
The repository of data models is closely connected with the Central Vocabulary and the Registry of Ciphers, which are also part of the Platform for Semantic Interoperability (PZSI).
