Open Information Model 1.0

The Open Information Model provides a syntax-independent model for XBRL data, allowing reliable transformation of XBRL data into other representations. The work product includes:

• The Open Information Model (OIM): a syntax-independent definition of an XBRL report.
• xBRL-XML: mappings from the original XML-based syntax for XBRL to the OIM.
• xBRL-JSON: a standard JSON representation for XBRL data, defined in terms of the OIM.
• xBRL-CSV: a standard for representing an XBRL report using CSV files.
• OIM Common: common definitions used by other OIM-based specifications.
