To assist customers working with the ever-increasing volume of XBRL taxonomies and frequent updates, XMLSpy includes a convenient XBRL Taxonomy Manager that provides a centralized way to install and manage XBRL taxonomies for use across all Altova XBRL-enabled applications.

The XBRL Taxonomy Manager will launch when you open an XBRL document for which the taxonomy is not installed, and you can also access the XBRL Taxonomy Manager from the Tools menu in XMLSpy.

Alternatively, if you are working within a secure network and need to manually download taxonomies, you may access them here.
