> * A simple declarative means for a user to interact with handle

> * Uses the ANSI/NISO OpenURL Framework to query handle and
>   receive back a structured XML response. (OpenURL drafts posted
>   at <http://library.caltech.edu/openurl/Public_Comments.htm>)
> 
> * Alternate responses could include resolution to stored URI,
>   service referral, etc
> 
> * OpenURL Framework allows contextual information to be bundled along
>   with the query/response messaging
> 
> * An RDF schema (using OWL) is defined for the ContextObject Format
>   of the OpenURL Framework
> 
> * A handle is given as an OpenURL Referent Identifier - the full
>   handle record is then returned as Referent Private Data
> 
> * An RDF Schema is defined for a handle record - supports the
>   predefined handle types HS_ADMIN, HS_SITE, HS_SERV, HS_PRIMARY,
>   HS_ALIAS, HS_VLIST
>  
> * Service data is passsed up as ServiceType Identifiers (for service
>   directives - eg authoritative query, etc) or as ServiceType
>   Metadata (service filtering - on index/type), and is passed back
>   as ServiceType Private Data (service messages)
> 
> * Controversial point - handle references are given compactly in
>   handle URIref form - eg <hdl://0.NA/1006#index=200> indicates
>   the handle value at index 200 for the handle 0.NA/1006
> 
> * Handle URIref form is how a handle client would address into a
>   handle resource - suggest that an alternate means of filtering
>   handle values is to use a fragment identifier syntax, eg
>   <#index=2;type=url> to return values of type URL at index 2 
> 
> * In sum - Resource Description Framework over OpenURL Framework
