Subject: [OASIS Issue Tracker] (EMERGENCY-135) General input regarding CAP Event Terms List

    [ https://issues.oasis-open.org/browse/EMERGENCY-135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=70347#comment-70347 ] 

Rex Brooks commented on EMERGENCY-135:

From EM CAP SC Meeting Notes for 6-29-2018:


Norm noted that we have looked at this several times before and we settled on providing a way to map different event terms lists to our list so that individual countries, groups like the International Red Cross, Red Crescent, etc. can use their preferred list but they can be correlated to the OASIS CAP list. If anyone does not have an existing event terms list they are welcome to use the OASIS event terms list.


Rex suggested we respond to this by saying that anyone is welcome to develop a rigorous official ontology that can be referenced by our list. Elysa noted that this seems to be covered in item 3 in their response.


Norm noted in relation to their items 4 and 5 that CAP is not intended to be exhaustive for all details of a given subject-event. Its job is to handle alerting, not provide complete information.

>             Project: OASIS Emergency Management TC
>          Issue Type: Improvement
>          Components: EDXL-CAP 
>         Environment: CAP Event Terms List
>            Reporter: Elysa Jones
>            Assignee: Jacob Westfall
>            Priority: Major
> The UK Met Office suggests that:
> 1. Terms really ought to be part of a formal taxonomy, rather than a single controlled list of terms. The taxonomy would clarify the broader/narrower aspects.
> 2. Many domains have used single hierarchy controlled lists for use within their domain, and cross-domain use, as in CAP, has not really been considered.
> 3. In practice, there may be different authoritative owners for what appear to be the same specific terms. Meteorology and aviation have this. 
> 4. Best practice in meteorology is to alert for the impact, rather than a specific ‘observable’ or term. For example, 25mm of rain in one hour may have no significant effect in a dry region, but if there has already been significant rain, and rivers, reservoirs, etc., are close to overflowing, the impact could be life critical.
> 5. The impact may be significantly different for different end user communities. E.g. a Severe Thunderstorm may be one with lots of lightning for people re-fuelling aircraft, whereas for an horticulturalist, it is one with big hailstones that would require them to move their workers out of their glass greenhouses for the duration, and the risk from the lightning is negligible.
> Any effort to develop an international "event terms list" would be better spent establishing mechanism to link to existing authoritative vocabularies, and the existing vocabularies consider exposing their terms in the context of ontologies, RDF and Linked Data, so that extra, explanatory information can be exposed and processed if required.
