Re: [CODE4LIB] it's cool to hate on OpenURL (was: Twitter annotations...)
Here is the API response Umlaut provides to OpenURL requests with standard scholarly formats. This API response is of course to some extent customized to Umlaut's particular context/use cases, it was not neccesarily intended to be any kind of standard -- certainly not with as wide-ranging intended domain as OpenURL's 1.0 intent (which never really caught on), it's targetted at standard actually-existing link resolver use cases in the scholarly environment. But, here you go, live even: http://findit.library.jhu.edu/resolve/api?sid=google&auinit=AB&aulast=Miller&atitle=Reporting+results+of+cancer+treatment&id=doi:10.1002/1097-0142%2819810101%2947:1%3C207::AID-CNCR2820470134%3E3.0.CO%3B2-6&title=Cancer&volume=47&issue=1&date=2006&spage=207&issn=0008-543X Json is also available. Note that complete results do not neccesarily show up at first, some information is still being loaded in the background. You can refresh the URL to see more results, you'll know when the back-end server has nothing left to give you when true is present. Another XML response with embedded HTML snippets is also available (in both XML and Json): http://findit.library.jhu.edu/resolve/partial_html_sections?sid=google&auinit=AB&aulast=Miller&atitle=Reporting+results+of+cancer+treatment&id=doi:10.1002/1097-0142%2819810101%2947:1%3C207::AID-CNCR2820470134%3E3.0.CO%3B2-6&title=Cancer&volume=47&issue=1&date=2006&spage=207&issn=0008-543X Ross Singer wrote: On Fri, Apr 30, 2010 at 10:08 AM, Eric Hellman wrote: OK, what does the EdSuRoSi spec for OpenURL responses say?

Well, that's what the "Community Profiles" are. So now you have TWO long, dense, boring documents to read -- the standard and the profile! The main game in town for Making OpenURL 1.0 Usable (maybe still the only game, come to think of it) is the San Antonio Profile, or SAP for short, which you can get here: http://alcme.oclc.org/openurl/docs/pdf/SanAntonioProfile.pdf Happily, it's only eight pages long (i.e. the same length as the entire original OpenURL 0.1 specification). The bad news is, they are incredible dense pages. Sample statement: D.5.5 Transports Transports define how to transport representations of ContextObjects over the network. Table D.7 lists the Transports supported by the San Antonio Community Profiles. The By-Value OpenURL Transport and the By-Reference OpenURL Transport (over HTTP and HTTPS) may be used to transport ContextObjects represented by means of the Key/Encoded-Value and the XML ContextObject Format. In case of the Key/Encoded-Value representation, only a single ContextObject may be transported. In case of the XML representation, one or more ContextObjects may be transported. The Inline OpenURL Transport may only be used to transport a single ContextObject represented using the KEV ContextObject Format. Have fun with that!

Re: [CODE4LIB] it's cool to hate on OpenURL (was: Twitter annotations...)
Hi All, Though hesitant to jump in here, I agree with Owen that the dead ends aren't a standards issue. The bloat of the standard is, as is the lack of a standardized response format, but the dead ends have to do with bad metadata being coded into open-URLs and with breakdowns in the connection between content aggregators/providers and knowledge base maintainers. Work in this area isn't completely stagnant, though. The joint NISO/UK Serials Group's "Knowledge Bases And Related Tools working group" is looking towards solutions to exactly these problems. http://www.uksg.org/kbart Their initial report on best practice for content providers and KB maintainers is worth a look. -Corey Owen Stephens wrote: Dead ends from OpenURL enabled hyperlinks aren't a result of the standard though, but rather an aspect of both the problem they are trying to solve, and the conceptual way they try to do this. I'd content these dead ends are an implementation issue - and despite this I have to say that my experience on the ground is that feedback from library users on the use of link resolvers is positive - much more so than many of the other library systems I've been involved with. What I do see as a problem is that this market seems to have essentially stagnated, at least as far as I can see. I suspect the reasons for this are complex, but it would be nice to see some more innovation in this area.

Although part of the problem is that you might want to offer any service on the basis of an OpenURL the major use case is supply of a document (either online or via ILL) - so it strikes me you could look at DAIA http://www.gbv.de/wikis/cls/DAIA_-_Document_Availability_Information_API ?

Since a resolver is under no obligation to do anything but present a web page it's difficult for local entrepreneurial types to build upon the infrastructure simply because there are no guarantees that it will work anywhere else (or even locally, depending on your vendor, I suppose), much less contribute back to the ecosystem. Umlaut was able to exist because (for better or worse) SFX has an XML output. It has never been able to scale horizontally, however, because to work with another vendor's link resolver (which should actually be quite straightforward) it requires a connector to whatever *their* proprietary API needs. I could definitely see a project like Umlaut providing a 'de facto' machine readable response for SAP 1/2 requests that content providers could then use to start offering better integration at *their* end. This assumes that more than 5 libraries would actually be using it, however. -Ross.

You are right. Z39.88 and (by extension) COinS really only defines the ContextObject itself. So it defines the carrier "package", it's administrative elements, referents, referrers, referringentities, services, requester and resolver and their transports. It doesn't really specify what should actually go into any of those slots. The idea is that it defers to the community profiles for that. In the XML context object, you can send more than one metadata-by-val element (or metadata-by-ref) per entity (ref, rfr, rfe, svc, req, res) - I'm not sure what is supposed to happen, for example, if you send a referent that has multiple MBV elements that don't actually describe the same thing. -Ross.

Absolutely. There is no inherent reason that an OpenURL has to be a plain text link that must be manually clicked nor is there any requirement that the resolver simply return an HTML page that may or may not contain plain text links the user can click on. An obvious thing for a resolver to be able to do is return results in JSON so the OpenURL can be more than a static link. But since the standard defines no such response, the site generating the OpenURL would have to know something about the resolver. > What I do see as a problem is that this market seems to have essentially > stagnated, at least as far as I can see. I suspect the reasons for this are > complex I suspect they are simple. The easy part of OpenURL addresses a compelling use case, but there just isn't that much pressure to take things to the next level. If people really got that upset about dead links -- and in many systems this is impossible because you'll be offered ILL fulfillment if no electronic copy is available -- there would be more incentive to handle resolution before the user clicks on the link. In short, you reach a point of diminishing returns with OpenURL very quickly. kyle

You are right, the 129 page spec of Z39.88 only deals with these in examples, and IIRC does not even decent pointers to the following: There are some "Core Metadata formats" registered under http://alcme.oclc.org/openurl/servlet/OAIHandler?verb=ListRecords&metadataPrefix=oai_dc&set=Core:Metadata+Formats notably info:ofi/fmt:kev:mtx:book and info:ofi/fmt:kev:mtx:journal : < http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:book >, < http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:journal >. As for the semantics of the fields defined there, the "description" is certainly not strictly defined in any sense but you can already see that there is potential for confusion and especially no canonical way (no way at all?) to achieve satisfying descriptions for several kinds of non-mainstream objects: * scholarly articles originally published online (when a "journal context" cannot be constructed) * articles in books which are not by coincidence conference proceedings ... ciao Thomas Berger -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (Cygwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iJwEAQECAAYFAkvamhkACgkQYhMlmJ6W47P/vQP/XfExoDcfEuMGIgFUw4z4GOiM LhFsKPkVR7wHKDgB+mEF+xnDJoP549Y31YEYKc5lMMz5fVMONUDwwiavVL6IdDvL EU2jDOQO+WnLiw1XENYoTiuEP6bxyF+gojlBlEN7De1OlCJ97gqitwz6owmTxvp0 BfjBcj4X8//5KVMD0rw= =1a4i -END PGP SIGNATURE-
Re: [CODE4LIB] it's cool to hate on OpenURL (was: Twitter annotations...)
Dead ends from OpenURL enabled hyperlinks aren't a result of the standard though, but rather an aspect of both the problem they are trying to solve, and the conceptual way they try to do this. I'd content these dead ends are an implementation issue - and despite this I have to say that my experience on the ground is that feedback from library users on the use of link resolvers is positive - much more so than many of the other library systems I've been involved with. What I do see as a problem is that this market seems to have essentially stagnated, at least as far as I can see. I suspect the reasons for this are complex, but it would be nice to see some more innovation in this area.

Ha! One of the things OpenURL 1.0 "fixed" was to wire in UTF-8 encoding. Much of the MARC data in circulation also uses UTF-8 encoding. Some of it even uses it correctly.

Hmm, this is wrong on so many levels. First, SGML was pretty darn good for its *purpose*, but it was a geeks dream and pretty scary for anyone who hacked at it not fully getting it (like most normal developers). As with many things where the learning curve is steep, it fell into the "not good for normal consumption" category and they (well, people who cared, and made decisions about the web) were "forced" to make XML. But JSON? Are you sure you've got this figured out? JSON as a object serializing format is good for a number of things (small footprint, embedded type, etc.), but sucks for most information management tasks. However, I'd like to add here that I happen to love XML, even from an integration perspective, but maybe that stems from understanding all those tedious bits no one really cares about about it, like id(s) and refid(s) (and all the indexing goodness that comes from it), canonical datasets, character sets and Unicode, all that schema craziness (including Schematron and RelaxNG), XPath and XQuery (and all the sub-standards), XSLT and so on. I love it all, and not because of the generic simplicity itself (simple in the default mode of operation, I might add), but because of a) modeling advantages, b) cross-environment language and schema support, and c) ease of creation. (I don't like how easy well-formedness breaks, though. That sucks) But I mention all this for a specific reason ; MARCXML is the work of the devil! There's a certain dedication needed for "doing it right", by paying attention in XML class, and play well with your playmates. This is how you build a community and understanding around standards; the standards themselves are not enough. The library world did nothing of the kind ; http://shelter.nu/blog/2008/09/marcxml-beast-of-burden.html The flaws of XML can most likely be traced back to people not playing well with playmates, and not the format itself. > May brother Ted Nelson enlighten all of > us - he not only hates XML [1] and similar formats but also proposed an > alternative way to structure information even before the invention of > hierarchical file systems and operating systems [2]. Bah. For someone who don't see the SGML -> XML -> HTML transgression as an inherited and more rigid structure (or, by popular language, more schematic) as a document model as a good thing, I'm not impressed. Any implied structure can be criticized, including pretty much any corner of Xanadu as well. (I mean, seriously; taking hypermedia one step closer to a file system does *not* solve problems with the paper-based document model of HTTP, it just shifts the focus) > In his vision of Xanadu > every piece of published information had a unique ID that was reused > everytimes the publication was referenced - which would solve our problem. *Having* an identifier doesn't mean that identifier is a *good* one, nor that it solves your problem. There's plenty of systems out there where everything has an identifier (and, if you knew XML deeper, you'll find identification models as well in there, but people don't use them because the early onset of XML didn't understand nor need them). Have a look at the failed XLink brooha for something that worked and filled the niche, but people didn't get nor did tool-makers see the point of implementation, and the thing died a premature death. The current model of document structure and XQuery is somewhat of an alternative, but people are also switching to CSS3 styles as well. The thing is, just because you've got persistence in a system of identifiers, it does not follow that the information is persisted; the problem of change is *not* solved in neither systems, and so we work with the one we got and make the best of it. One thing I always found intriguing about librarians were their commitment to persistent URIs for information resources, and use of 303 if need be (although I see this mindset dwindling). I think you're the only ones in the entire world who gives a monkeys bottom about these issues, as the rest of the world simply use Google as a resolver. I can see where this is going. :) Regards, Alex -- Project Wrangler, SOA, Information Alchemist, UX, RESTafarian, Topic Maps --- http://shelter.nu/blog/ -- -- http://www.google.com/profiles/alexander.johannesen ---

Hear hear.
I'm actually encouraged by Benjamin's linking (har har) to the httpRange-14 issue as being relevant
to the concept of "link resolution", or at least redirection (indirection?) using URL
surrogates for resources. Many are critical of the TAG's "resolution" (har har har) of
the issue, and think it places too much on the 303 redirect.
I'm afraid I still don't understand the issue fully enough to comment — though I'd love
to hear from any who can. I agree with Eric's hope that the library world can look to
W3C's thinking to inform a "better way" forward for link resolving, though.
One key thing to remember with the W3C work is that URL's have to be
dereference-able. I can't lookup (without an OpenLink resolver or Google
or the like) a url:isbn:{whatever}, but I can dereference
http://dbpedia.org/resource/The_Lord_of_the_Rings -- which 303's to
http://dbpedia.org/page/The_Lord_of_the_Rings -- which is full of more
/resource/ dereferencable (via 303 See Other) URL's.
The main thing that the W3C was trying to avoid was RDF that
inadvertently talks about online documents when what it really wants to
talk about is the "real thing." Real things (like books) need a URI, but
ideally a URI that can be dereferenced (via HTTP in this case) to give
them some information about that real thing--which isn't possible with
the urn:isbn style schemes.
That's my primitive understanding of it anyway. Apologies if any
overlaps with library tech are off. :)

Actually, no, I won't mention that. Carry on. MJ
