Metadata

Interconnected, machine readable data, at scale

The NGA provides a free database with no regulations on its use. MaxMind takes some coordinates from that database and slaps IP addresses on them. Then IP mapping sites, as well as phone carriers offering “find my phone” services, display those coordinates on maps as distinct and exact locations, ignoring the “accuracy radius” that is supposed to accompany them.

“We assume the correctness of data, and often these people who are supposed to be competent make mistakes and those mistakes then are very detrimental to people’s daily lives,” said Olivier. “We need to get to a point where responsibility can be assigned to individuals who use data to ensure that they use the data correctly.”

From Kashmir Hill writing on the role of interconnected data in our modern lives. In this case it’s geo IP data, but it’s a story that’s increasingly common and likely in any field.

Two years after MaxMind first became aware of this problem with default [geo IP] locations, its lawyer says it’s still trying to fix it.

Facebook’s Favorite Metadata

Facebook’s guide to sharing details some meta tags to make that sharing work better:

In order to make sure that the preview is always correctly populated, you should add the tags shown below to your html. An example news story could have the following:

<meta name="title" content="Smith hails 'unique' Wable legacy" />

<meta name="description" content="John Smith claims beautiful football is the main legacy of Akhil Wable's decade at the club. " />

<link rel="image_src" href="http://www.onjd.com/design05/images/PH2/WableAFC205.jpg" />

As shown, title contains the preview title, description contains the preview summary and image_src contains the preview image. Please make sure that none of the content fields contain any html markup because it will be stripped out. For consistency’s sake, please use the

tag to provide text data for the preview, and the

tag for any source urls.

The title and summary tags are the minimum requirements for any preview, so make sure to include these two.

Is Automated Metadata Production Really The Answer?

(It’s old, but I just stumbled into it again…) Karen Calhoun’s report, The Changing Nature of the Catalog and its Integration with Other Discovery Tools, included a lot of things I agree with, but it also touched something I’m a bit skeptical about: automated metadata production. Some interviewees noted that today’s catalogs are put together […] » about 300 words

Microformats

Oliver Brown introduced me to microformats a while ago, the Ryan Eby got excited about them, then COinS-PMH showed how useful they could be for libraries, but I still haven’t done anything with them myself (other than beg Peter Binkley to release his COinS-PMH WordPress Plugin). What are microformats? Garrett Dimon explains the theory: When […] » about 400 words

Library Integration Stuff

I’d meant to point out these two articles from Library Journal ages ago, but now that I’m putting together my presentations for next week (NEASIS&T & NELINET), I realized I hadn’t.

Roy Tennant writes in Doing Data Differently that “our rich collections of metadata are underused.” While Roland Dietz & Carl Grant, in the same issue, bemoan the dis-integrated world of library systems.
