Resumo(s)
The current financial crisis has demonstrated that there is a need for financial accounting data in a format which can be rapidly analyzed and exchanged. The appearance of XBRL in 2000 has helped create a ‘de facto’ standard data format for the exchange of financial information. However, XBRL by itself is not capable of ensuring a common semantic for the exchange of accounting information. Additionally, the existence of different accounting standards in different countries is a hindrance to efficient analysis and evaluation of companies by international analysts or investors. Therefore, there is a need to not only use a more advanced data format, but also for tools which can facilitate the exchange of accounting data, in particular when different accounting standards are used. This dissertation presents a tuple-based semantic and structural mapping for interoperability establishment of financial information models based on the use of ontologies and a ‘Communication Mediator’. It allows the mapping of accounting concepts of different accounting standards to be stored in the ‘Communication Mediator’. The mapping stored contains an ATL code expression, which with the aid of model transformation tools, can be utilized to perform the mapping between two different accounting models.
