[Handle-info] OpenHandle Project: Q & A

Title: OpenHandle Project: Q & A

Hi Eamonn:

Thanks for the questions. Some answers. (I’ve also included a couple of questions for CNRI. :) Bottom line is for interested parties to mail myself (or Chris T.) to get added as a project member and to contribute if you think having structured handle values on the Web is a good thing.

Cheers,

Tony

    * OpenHandle Project

    The OpenHandle project is an open-source project hosted on Google Code:

        http://code.google.com/p/openhandle/

    Anybody interested in contributing - code or documentation - should mail one of the project owners to be added as a project member:

        mailto:tony.hammond@gmail.com
        mailto:christopher.townson@gmail.com

    * OpenHandle Documentation

    Oops! I seem to have dropped a couple links. I’ll try and make this much more explicit by reworking some of the page links, but to get a listing of all the wiki pages see here:

        http://code.google.com/p/openhandle/wiki 

    Or choose the ‘Wiki’ tab. There is already quite a number of pages listed. Feel free to add to the documentation of existing pages or to add new pages. There’s also a ‘To Do List’.    

    * OpenHandle Binaries:

    Basically the OpenHandle application is a Java servlet. The project build is managed by Maven and .jar files are downloaded from a Maven repo. If CNRI were to include the handle client library .jar within a public Maven repo then we could put up the .war file which would then be a drop-in web service.

    Q:  Would CNRI be able to make the HCL .jar available to Maven? Or is there some counterproposal for facilitating project builds?

    * OpenHandle Services

    Currently Nature is hosting a test service for this project at

        http://nascent.nature.com/openhandle/handle?

    There is no commitment (at least at this time anyway) to maintain this service. We do, however, envisage that there would be a number of publicly available OpenHandle services which might be registered. As a registration test we have registered the above service under the handle

        hdl:10100/openhandle

    Note that this handle could later be superseded by a more authoritative version which could likewise maintain a directory of public OpenHandle services.

    It would be (more than) interesting (in fact, it would be extremely helpful) if CNRI were to consider running its own OpenHandle service which presumably would carry a better commitment than we can currently pledge. The advantage for CNRI would be twofold:

        a) to provide a web-based gateway to structured handle value data

        b) to guide development of OpenHandle and ensure that it remains faithful to the handle specs

    Q:  Would CNRI be willing to host an OpenHandle service?

    * OpenHandle Writeable

    A proposed extension to OpenHandle to make it writeable would be to have something like a JSON API for web services based admin. See the page here:

        http://code.google.com/p/openhandle/wiki/HandleAdminApiJson

    This could form a useful halfway house between the text API for the bundled command line admin tool and native Java code. Both ideas and development needed.

I've been to the website, but it appears that I will need to build from the source code (possibly no bad thing but I'm lazy: a virtue so I'm told) and there aren't any instructions in the jar (and I'm not sure what the velocity.properties file implies as a requirement). If there are some docs somewhere that I've missed that would be great (or let me know if you want help to write some).
