          When a resource has no narrative, only systems that fully understand the data can display
           the resource to a human safely. Including a human readable representation in the resource
           makes for a much more robust eco-system and cheaper handling of resources by intermediary
           systems. Some ecosystems restrict distribution of resources to only those systems that
           do fully understand the resources, and as a consequence implementers may believe that
           the narrative is superfluous. However experience shows that such eco-systems often open
           up to new participants over time.

      The effective period for a evidence  determines when the content is applicable for usage
       and is independent of publication and review dates. For example, a measure intended to
       be used for the year 2016 might be published in 2015.
      Allows establishing a transition before a resource comes into effect and also allows for
       a sunsetting  process when new versions of the evidence are or are expected to be used
       instead.

The determination of when to create a new version of a resource (same url, new version)
       vs. defining a new artifact is up to the author.  Considerations for making this decision
       are found in [Technical and Business Versions](resource.html#versions). 

In some cases, the resource can no longer be found at the stated url, but the url itself
       cannot change. Implementations can use the [meta.source](resource.html#meta) element to
       indicate where the current master source of the resource can be found.

      The date on which the resource content was last reviewed. Review happens periodically
       after approval but does not change the original approval date.
      
      Gives a sense of how &quot;current&quot; the content is.  Resources that have not been
       reviewed in a long time may have a risk of being less appropriate/relevant.

      The effective period for a evidence  determines when the content is applicable for usage
       and is independent of publication and review dates. For example, a measure intended to
       be used for the year 2016 might be published in 2015.
      Allows establishing a transition before a resource comes into effect and also allows for
       a sunsetting  process when new versions of the evidence are or are expected to be used
       instead.

       found by topical searches.
