* Potentially use "role" and "arcrole" from xlink to capture all the semantics of DCP-3.
 
* Should we change DCP-4 to the current OPeNDAP suggestion, or should there be a separate DCP for the more general case of DCP-4?
 
* Brian suggests a separate DCP for the general case (e.g., using "arcrole"), this will be coming in DCP-5
 
** Basically, covering the case where service casts refer to collections, or collection casts referring to services
 
* Returning a collection cast is a different use case from returning OPeNDAP response
 
* Pedro suggests you don't need to use something like arcrole, IANA has registered mime types and rels that should cover everything
 
* Summary -> DCP-4 will use xlink role, DCP-5 will use xlink role and arcrole

* More aligned with OGC use of OpenSearch
 
* dc:date refers to "point or period of time for an event associated with a resource"
 
* should we use the convention that the parameter and XML element should match?
 
* dc:date is more standard than the OpenSearch parameters
 
* time:start and time:end were only standardized as "queryable"
 
* which does ESRI prefer or suggest based on client development?
 
** ESRI would align more with the dc approach (since there is already a dc:date XML element)
 
** Not a big deal either way, but prefer things that may become standardized
 
* another option (considered by OGC) is using gml, but this is more complex
 
* Brian seeking connection between parameters and response elements in OSDD; however, OSDD does not support this
 
** Only potential mechanism is "rel" and "type"
 
* Eric also suggests using the "rel" list capabilities of OpenSearch to tell clients of this "convention"
 
* The response may not actually echo all the values for search parameters
 
* Another avenue is to use the Query tag is someway
 
* Could use the <Content> tags to put whatever data you want
