There is an every-increasing amount of data available, which enterprises can leverage to their competitive advantage. While decision makers require an integrated view over information, relevant data typically originates from a vast variety of disparate sources.

The Financial Information Observation System (FIOS) provides a web-based Online Analytical Processing (OLAP) interface for multi-company analysis over an integrated dataset, consisting of XBRL data from the Security and Exchange Commission (SEC) and the Federal Financial Institutions Examination Council (FFIEC) as well as open web data from Wikipedia/DBpedia and Freebase.

With FIOS we show how to merge XBRL data (from SEC EDGAR and the FFIEC) with freely-available Semantic Web data (from Wikipedia and Freebase). Our system uses increasingly popular Linked Data principles for accessing and encoding data. We use standard open-source tools to transform and make openly available SEC EDGAR and FFIEC data according to Linked Data principles, and to collect and integrate data from various sources. The FIOS user interface abstracts the underlying RDF data format of Linked Data away from the user and bases interaction on intuitive and interactive operations on well-known OLAP data cubes and operations.
