XBRL: Extraction of Business Financial Information from XBRL Documents

XBRL is a package suited to extract business financial information from an Extensible Business Reporting Language (XBRL) instance file and the associated collection of files that defines its Discoverable Taxonomy Set (DTS). These files are usually disseminated across different remote locations. XBRL documents employ many technologies defined by XML standards, such as XML Schema, Namespaces, XLink, and XPath, which make the extraction of information involved. The functions provided by this package address this complexity, returning data frames containing the enclosed information readily available to perform analyses. XBRL has been successfully tested in analyzing 10-K and 10-Q submissions from USA filing companies that are publicly available at the EDGAR system of the Securities and Exchange Commission (SEC). As published taxonomy files (such as "http://xbrl.fasb.org/us-gaap/2013/elts/us-gaap-2013-01-31.xsd") are immutable and are used by most filers, XBRL offers the option of downloading them only the first time they are referred, keeping a local cache copy that can be used from then on. This speeds-up the process, specially on slow connections. XBRL is not and does not aim to be (at least yet) a validating XBRL processor. XBRL is still a work in progress. As such, functions and produced data frames may change structure in future versions until stabilization.
