FW: OpenHandle: Google Code Project

Sorry 'bout this, but I'd better fix those refs:

[1] http://www.handle.net/
[2] http://nascent.nature.com/openhandle/handle?
[3] http://code.google.com/p/openhandle/
[4] http://www.ietf.org/rfc/rfc3650.txt
[5] http://www.ietf.org/rfc/rfc3651.txt
[6] http://www.ietf.org/rfc/rfc3652.txt

I had the RFCs incorrectly numbered.

Tony

> Hi:
> 
> The OpenHandle project aims to exposes Handle [1] records in various common
> serializations: RDF/XML, RDF/N3 and JSON. The demo service is very much a
> work in progress and is located on one of our dev servers [2]. The project
> is open source (GPL) and the code and project wiki are available on Google
> Code [3].
> 
> For those who may not be familiar with Handle, the Handle System [4,5,6] is
> a directory service which is used by a growing number of organizations and
> projects  - DOI, ADL, DSpace, etc. - to provide identification and
> resolution services on the Internet. The Handle System runs on its own
> dedicated network protocol and the reference implementation is in Java.
> Hence the driver for this effort to expose handle records as open
> descriptions retrievable from a web service and accessible to multiple
> languages.
> 
> The current release fixes some of the terminology and structures and aligns
> better with RFC 3651 [5]. Specifically:
> 
>     1. Handle namespace URI is now dereferencable (returns an RDF schema -
> still under development): <http://hdl.handle.net/10100/handle.rdfs#>
>     2. Follows RFC 3651 more strictly
>     3. Handle value fields are now respected
>     4. Native handle types (per the RFC) are represented as RDF classes
>     5. Querystring parameters added:
> 
>         a) id - handle
>         b) index - select handle value index
>         c) type - select handle value type
>         d) format - select format ("rdf", "n3", "json")
>         e) mimetype - override mimetype
> 
> Additionally the service now offers multiple representations:
> 
>     1. RDF/XML
>     2. RDF/N3
>     3. JSON
> 
> These are accessible using the key/val pairs: "format=rdf", "format=n3",
> "format=json". They are served up with the correct mimetypes:
> 
>     1. application/rdf+xml
>     2. text/rdf+n3
>     3. application/json
> 
> This may not result in the best presentation in the browser, in which case
> an override "mimetype" parameter is provided so that the formats can be
> returned with a user-specified mimetype, e.g. "mimetype=application/xml" for
> RDF/XML, or "mimetype=text/plain" for RDF/N3 and JSON.
> 
> Note, as yet the queries do not support HTTP content negotiation but this is
> being addressed.
> 
> The webapp code is available as an open source project on Google Code [3]
> under the GPL licence. The site makes the following resources available:
> 
>     1. OpenHandle webapp code in subversion
>     2. Handle RDF schema, war file and source jar downloads
>     3. Wiki for project development
> 
> We'd be very interested in receiving feedback on this project - either on
> the list or on the project wiki.
