I&#8217;ve been looking for that one standardized definition and of course, I could not find one &#8211; again, in the context of data governance, I see this as another irony.<\/p>\n<p>One thing that&#8217;s agreed upon is that managing reference data is important.

For example, the &#8220;new&#8221; Euro currency became into effect on January 1st, 1999 and redemption after legal tender of the currency it replaced is considered indefinitely, in some cases, and in some cases they have an official date.<\/li>\n<li>Shared by multiple systems within or outside the enterprise\u00a0\u2013 For example, the list of countries, sex and gender codes, types of diseases, units of measurement, etc.<\/li>\n<li>It does not describe things that the enterprise does business with, but rather it categorizes the data which describes the enterprise&#8217;s transactions and master data \u2013 Such as the type of products, status of the orders, location of the customers, etc.<\/li>\n<li>Each piece of data has a distinct definition \u2013 Ex: the type of an organization could be a corporation, foundation, government corporation, non-profit organization, and so on, each with its specific definition<\/li>\n<li>Often defined by 3<sup>rd<\/sup> party bodies \u2013 Ex: ISO, UN, WHO, etc.<\/li>\n<\/ul>\n<p>Besides being defined by the 3rd party bodies, which are either business domain specific and\/or world-wide such as World Health Organization, they can also be organization specific.
