Advance interoperability in e-government with standardised core directories
Many new requirements for the public sector arise from the change of the society and the "Age of Knowledge". Globalisation leads administrations to become more interoperable, irrespective of national borders. To meet these requirements, administrations and IT systems need to become more efficient. One of the main principles in software engineering is reusability. This can be applied on all levels. There is still a lot of potential at the content level. The idea of reusing content is not new but especially in federal structures where central solutions are nearly impossible this is a great challenge. The document describes an approach that allows information to be collected in a decentralised way and makes it available in an interdisciplinary manner and across regional borders. Core Directories will be designed and used as an infrastructural component to make them accessible for multiple applications. In order to share information, data interoperability standards are needed.
