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.

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. > > Cheers, > > Tony > > > [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/rfc3150.txt > [5] http://www.ietf.org/rfc/rfc3151.txt > [6] http://www.ietf.org/rfc/rfc3152.txt > > > ****************************************************************************** > ** > DISCLAIMER: This e-mail is confidential and should not be used by anyone who > is > not the original intended recipient.
