skos as atom

Wednesday, November 4, 2009

I’ll be the first to admit the tone and content of my last post was a bit off kilter. I guess it was pretty clear immediately from the title of the post. Chalk it up to a second night of insomnia; and also to my unrealistic and probably unnecessary goal of bringing the Atom/REST camp [...]

premis v2.0 and schema munging

Monday, July 21, 2008

In an effort to get a better understanding of PREMIS after reading about the v2.0 release, I dug around for 5 minutes looking for a way to convert an XML Schema to RelaxNG. The theory being that the compact syntax of RelaxNG would be easier to read than the XSD.
I ended up with a little [...]

MIME types and library metadata

Wednesday, April 23, 2008

While thinking about library metadata and RESTful web services I got to wondering how many application/*+xml MIME types have actually been registered. It turns out that 120 out of the 633 other application/* MIME types.
Does it seem like a generally useful thing to be able to identify metadata representations with MIME types? Rebecca Guenther [...]

app and repositories

Monday, July 16, 2007

Pete Johnston blogged recently about a very nice use of the Atom Publishing Protocol (APP) to provide digital library repository functionality. The project is supported by UKOLN at the University of Bath and is called Simple Web-service Offering Repository Deposit (SWORD).
If you are interested in digital repositories and web services take a look at [...]

the weight of legacy data

Sunday, May 20, 2007

v0.97 of MARC::Charset was just released with an important bugfix. If you’ve had the misfortune of needing to convert from MARC-8 to UTF-8 and have used MARC::Charset >= v0.8 to do it you may very well have null characters (0×00) in your UTF-8 data. Well, only if your MARC-8 data contained either of the following [...]

oclc registry

Monday, February 19, 2007

So OCLC’s WorldCat Registry is a nice new addition to OCLCs growing list of web services. Do a search for your library and take a look at the URL: aye that’s right it’s SRU. In fact do a view source on the results page and you’ll see an SRU response in XML–the HTML is being [...]

identifiers and authority records

Saturday, January 6, 2007

Authority files are rather important for unambiguously talking about a person, place or thing. In database lingo they essentially amount to a primary key for a table. Given the time and effort libraries spend in maintaining authority records and assigning control numbers to individuals it makes sense that a URI could be assigned to an [...]

ruby-oai v0.0.3

Tuesday, September 19, 2006

v0.0.3 of ruby-oai was just released to RubyForge. The big news is that this release allows you to use libxml for parsing thanks to the efforts of Terry Reese. Terry is building a RubyOnRails metasearch application at OSU and, well, felt the need for speed.
After committing the branch he was working on I ran some [...]

xquery

Monday, June 12, 2006

So my new employer was kind enough to send me to Joint Conference on Digital Libraries this year. The JCDL program has caught my eye for a few years now, but my previous employer didn’t really see the value in being involved in the digital library community. It’s nice to be back listening to new [...]
