TEP and Extensions (Layers)

["Wilkins, Brian M" <bwilkins@mitre.org>]

For discussion at 2:00 …

 

From what I have gathered, there are three use cases here that we are trying to address. 

1.       Allowing a community to add entirely new data to augment a standard so it better suits them, such as adding Earthquake data to a CAP message.

2.       Allowing a community to supplement the default set of values with ones of their own choosing, such as extending the triage codes in TEP, and allow them to select one value.

3.       Allowing a community to supplement the default set of values with ones of their own choosing, such as extending the contingency medical specialty code in TEP, and allow them to select multiple values.

 

Here are two examples, based on Jeff’s work that I think might work.

Earthquake Addition -
