Towards extension of open data model: Relational data model context

Abstract

The main purpose for the use of open data (further OD) is to provide content. From the definition of OD there are two important attributes of OD: – machine readable format and reuse without any legal restriction. The issue of the so called “Open data” has recently been intensely investigated and discussed in detail. However, OD benefit can only be realized if the data are true, so called correct. There are a plenty of models of OD and their metrics, the proposed model extends one of the quality attributes called correctness. In the proposed model it seems preferable to use this aggregated attribute rather than individual attributes of quality.
