Handle Clients #1, #2, #3


thammond – 2008 October 01

In Handle

Three alternate clients for viewing a Handle (or DOI): #1 (sky - text), #2 (black - tuples), #3 (white - cards) - the image above is “clickable”. When Handle clients become JavaScript-able, one really can have it one’s own way. (The JavaScript library is here, the demo service interface here - the code for setting up a new service interface can be got from the OpenHandle project.)

The Last Mile


thammond – 2008 October 01

In Handle

The figure above (click to enlarge) is probably self-explanatory but a few words may be in order. With no end-to-end delivery of data from the Handle System to the user’s application (broswer or reader), getting data out of the Handle System has traditionally meant using the Web (ie. HTTP) as a courier - in effect, this is the “last mile” for Handle data. Typically an upstream (Handle) client provides services to the user.

Look Ma, No Plugins!

var f = function (OpenHandleJson) {   var h = new OpenHandle(OpenHandleJson);   var hv = h.getHandleValues();   for (var i = 0; i < hv.length; i++) {     var v = new HandleValue(hv[i]);     if (v.hasType(‘URL’)) {       print(v.getData());     }     else if (v.hasType(‘HS_ADMIN’)) {       var a = new AdminRecord(v.getData());       print(a.getAdminPermissionString())     }   } } "And that, gentlemen, is how we do that." - Apollo 13 Following on from my earlier Client Handle Demo post, this entry is just to mention the availability of a port of (part of) the Handle client library (in Java) to JavaScript: openhandle-0.

Multiple Resolution


thammond – 2008 August 22

In Multiple Resolution

I’ve been meaning for some time to write something about DOI and so-called “Multiple Resolution”, which to be honest is the only technology feature of any real interest as concerns DOI. (DOI as a business and social compact for guaranteeing name persistence of Web resources has been an extraordinarily successful venture in the academic publishing world with more than 32m items registered and maintained over eight years of operation but that may not have required any specialized technology. More a consensus to adopt a single location service in the DOI proxy.)

Multiple resolution, though. Now, that’s something else. Seems like it should be able to offer a lot of general funkiness and yet it has not been much used up to now. And I have to wonder why.

mod_prism (Updated)


thammond – 2008 August 21


I’ve just put up for comment a revised mod_prism (0.3) of the existing mod_prism RSS 1.0 module. This is now updated to the current PRISM version (v2.0) which was released in February ’08 and reissued with Errata in July ’08. The current mod_prism draft is registered here and hosted on the PRISM site here. The new draft charts all (five) versions of the PRISM specification (v1.0-v2.0) and maps PRISM terms to RSS 1.

Search Web Services - New Committee Drafts


thammond – 2008 July 29

In Search

As posted here on the SRU Implementors list, the OASIS Search Web Services Technical Committee has announced the release of five Committee Drafts, informally known as: Abstract Protocol Definition (APD) Binding for SRU 1.2 Auxiliary Binding for HTTP GET CQL 1.2 Binding for OpenSearch Links to specific document formats are given at the bottom of the mail. A list of the TC public documents is also available here.

Does Size Matter?


thammond – 2008 July 28

In Web

Interesting post from Google, in which they say: “Recently, even our search engineers stopped in awe about just how big the web is these days — when our systems that process links on the web to find new content hit a milestone: 1 trillion (as in 1,000,000,000,000) unique URLs on the web at once!” Puts Crossref’s 32,639,020 unique DOIs into some kind of perspective: 0.0033%. But nonetheless that trace percentage still seems to me to be reasonably large, especially in view of it forming a persistent and curated set.

Five Years


thammond – 2008 July 28

In Identifiers

Oh wow! A rather remarkable plea here from Dan Brickley on the public-lod mailing list which calls for the registrant of the DNS entry to top it up with another 5+ years worth of clocktime. Some quotes: _“The idea of such a cool RDF namespace having only 6 months left on the DNS registration gives me the worries.” “If you could add another 5-10 years to the DNS registration I’d sleep easier at night.

Knols and Citations


thammond – 2008 July 24

In Linking

So, Google’s Knol is now live (see this announcement on Google’s Blog). There’ll be comment aplenty about the merits of this service and how it compares to other user contributed content sites. But one curious detail struck me. In terms of citeability, compare how a Knol contribution (or “knol”) may be linked to as may be a corresponding entry in Wikipedia (here I’ve chosen the subject “Eclipse”): Knol http://knol.
