The research and implementation of XBRL data service platform

As there is no convenient and custom XBRL data service in the present market, in this article we designed the XBRL Data Service Platform in the perspective that a computer application can get the needed XBRL data conveniently. The platform parses the XBRL taxonomy and instance first, and then store the XBRL data in the combination of relational database and file system. The platform is designed in 3-tier architecture to provide data service. The work of Data Access Tier and Model Tier is to query and encapsulate the XBRL data; the Business Logical Tier is to complete the main logical work, to invoke the Data Access Tier to get the data, and then assembly and serialize the data, and return the result to the View Tier at last; View Tier opens the API list to public as web service, users may invoke the interface with an application. The test work shows that XBRL Data Service Platform's interface is simple and definite, and its function to get XBRL data is powerful. With the platform users can get both the specific XBRL data segments and the complete XBRL files as their needs. Furthermore, all the data requests are completed in a short response time. © (2013) Trans Tech Publications, Switzerland.
