Re: [CODE4LIB] One Data Format Identifier (and Registry) to Rule Them All

2009-05-08 Thread Jonathan Rochkind
I don't understand from your description how Topic Maps solve the identifying multiple versions of a standard problem. Which was the original question, right? Or have I gotten confused? I didn't think the original question was even about topic vocabularies, but about how to best provide an

[CODE4LIB] Curious about Cell Phone Barcode Scanning Apps

2009-05-08 Thread Matt Amory
I'm interested in some advice on building an app to pickup barcode data through a cell phone camera and return OPAC/Library Thing/WorldCat etc. results to a mobile interface. I know that Android has a UPC barcode reader linked to a shopping app, and I'm wondering if this can be used or repurposed,

Google provided the barcode-recognition line-interpolation software as open source for Android developers to build on. That explains why I have about 4 barcode-scanning apps on the G1. Note that most common cellphone camera's haven't advanced enough to get reliable resolution for barcodes, in

[CODE4LIB] exploiting z39.50

2009-05-08 Thread Eric Lease Morgan
How might I go about exploiting Z39.50 to extract specific MARC records from a library catalog? More precisely, I am trying to download sets of MARC records from remote library catalogs destined for a sort of union catalog. I see each of these records being identified with a specific
