[EPIC] Support XBRL Open Information Model (OIM) and multiple serialisation syntaxes (CSV, JSON, XML)

[sskagemo]

Add support for XBRL Open Information Model (OIM) and relevant syntaxes

There is a currently a candidate recommendation for a syntax independent information model for XBRL, with a set of accompanying syntaxes (XBRL-XML, XBRL-JSON, XBRL-CSV). A possible future enhancement of the reference implementation would be to add support for all these syntaxes.

The OIM provides new and simpler ways to work with XBRL data. It defines a model that represents the meaning of the standard, without referencing syntax specifics. It then defines multiple and interchangeable formats, which can be added to over time.

Right now, we support three different formats.

Want to collect huge quantities of granular data? xBRL-CSV lets you do that.
Want to make your XBRL data simple to use? xBRL-JSON is the answer.
Traditional approach working fine? xBRL-XML is your friend.
