oai2rdf

Thursday, August 24, 2006

Amidst the flurry of commit messages and the like on the simile development discussion list I happened to see the Simile Project includes a RDFizer project which has a component called oai2rdf.
oai2rdf is a command line program that happens to use Jeff Young’s OAIHarvester2 and some XSLT magic to harvest an entire oai-pmh archive [...]

(py)?lucene 1.9

Thursday, March 2, 2006

So on March 1st lucene v1.9 was released and the *next day* pylucene v1.9 is released. Nice work!
I guess there are a bunch of methods that are deprecated in 1.9 which will dissappear entirely in v2.0. Now would be a good time to update usage…

jython niceties

Friday, November 11, 2005

While playing around with the Java JDOM library, I found myself resorting to jython to experiment with the API. It’s just so much easier this way for me:

builder = SAXBuilder()
document = builder.build(StringReader(xml))
xpath = XPath.newInstance(’//foo/bar’)
node = xpath.selectSingleNode(document)
print node.getText()

In case it’s of [...]

pylucene

Thursday, June 9, 2005

I’m going to be doing a lightning talk tonight at the Chicago Python Group about pylucene. pylucene essentially lets you use the popular Lucene indexing library (Java) in Python. No time limit has been set for the lightning talks (and mjd won’t be there with his gong) but I hope to quickly cover how [...]

Communication

Friday, May 6, 2005

At my day job I’ve spent the better part of a month working on a nasty performance tuning problem in some software that I didn’t actually write. Without going into much detail we have a distributed application that provides cover images (a la Amazon) to the websites and other applications at various divisions with Follett. [...]
