Re: [CODE4LIB] Sending html via ajax -vs- building html in js (was: jQuery Ajax request to update a PHP variable)
I've been following this thread very closely, and find myself torn. Doing all the HTML generation server-side seems like the easiest way to have a single set of template code that's shared between JS and non-JS paths, reducing complexity of the overall app, and making graceful degradation easier. On the other hand, doing client-side HTML generation (or direct DOM updating) seems like it offers better performance, greatly reduced bandwidth, and a better fit if you want to create a reusable API. I think there is a third way: using the same template code for both client-side and server side rendering. The basic HTML version would retrieve pages rendered server-side, and the enhanced JS version would retrieve JSON and render the UI with the same templates (presumably with modular templates so the JS version would only have to update the areas with updated content, and not the entire page). The only template systems I know of that have both client and server support are XSLT and Mustache. Are there others? Has anybody set up a system like this? -Esme -- Esme Cowles escow...@ucsd.edu The wages of sin is death but so is the salary of virtue, and at least the evil get to go home early on Fridays. -- Terry Pratchett, Witches Abroad On 12/7/2011, at 9:38 PM, Jonathan Rochkind wrote: Also, I've thought of a good reason myself: performance.

While in general I tend toward the other the other thing you said, Does it make sense to replicate the server-side functionality on the client? -- I think what you propose above is legit. MOST people don't write interfaces like that, even in js. That is, an interface that will update the user interface even before/without receiving _anything_ back from the server. (But, in the best cases, produce and error message and/or 'undo' the user interface action iff the server does later get back with an error/failure message). So if you're going to do that, then--- it kind of doesn't matter if the server sends back HTML or JSON or anything else, the user interface is updating before/without getting _anything_ from the server. But to the extent the server's response then serves pretty much only as a notification-of-failure or whatever, yeah, JSON is the way to go. So, yeah, if you're going to go all the way there, that's a pretty cool thing (if you can make sure the failure conditions are handled acceptably), sure, go for it.
Re: [CODE4LIB] Models of MARC in RDF
Owen- Another strategy for capturing MARC data in RDF is to convert it to MODS (we do this using the LoC MARC to MODS stylesheet: http://www.loc.gov/standards/marcxml/xslt/MARC21slim2MODS.xsl). From there, it's pretty easy to incorporate into RDF. There are some issues to be aware of, such as how to map the MODS XML names to predicates and how to handle elements that can appear in multiple places in the hierarchy. -Esme -- Esme Cowles escow...@ucsd.edu Necessity is the plea for every infringement of human freedom.

Re: [CODE4LIB] Models of MARC in RDF
Owen- We assign ARKs[1] to our objects (and predicates for that matter). The issue of reconciling against other sources hasn't come as much, since we have mostly focused on our unique objects. But we have worked on that issue some. For example, several years ago, I worked on the UCAI project, where we mapped several slide collections to a common schema[2] and did quite a bit of work trying to build work records for the collections that didn't have them, and match work records across collections. That project didn't produce a copy-cataloging service like we'd hoped, though the Getty is now working on a registry[3] of works of art, which would the task of matching records a lot simpler. 1. https://wiki.ucop.edu/display/Curation/ARK 2. http://www.loc.gov/standards/vracore/ 3. http://www.getty.edu/research/tools/vocabularies/cona/index.html -Esme -- Esme Cowles escow...@ucsd.edu In the old days, an operating system was designed to optimize the utilization of the computer's resources.

Re: [CODE4LIB] Code4Lib 2011 Proposals
I've never been to Vancouver, so I don't know what the housing options are. But I wonder if there isn't some way to keep the nightly rate down. Maybe this could be addressed by having an official hostel/cheaper hotel? Perhaps UBC or some other institution has an inexpensive housing option (I've seen this at other universities). -Esme -- Esme Cowles escow...@ucsd.edu A person, who is nice to you, but rude to the waiter, is not a nice person.

It's good to be able to draw in students and people who are interested but not directly supported or who might choose to go on their own dime. These past two years the conf hotel rate has crept up some, with a good block rate but still well over $100/night. Vancouver's a more expensive town than any we've been in before, so I'd worry we'd be shutting some people out. I think there's been some kind of lower cost hotel or hostel option in every town, and surely there would be in Vancouver, but in a bigger town that means people are spread out more and then my concern (b) gets amplified, too.
