web documents and axioms for linked data

Monday, February 22, 2010

A few months ago I took part in a discussion on the pedantic-web list, which started out as a relatively simple question about FOAF usage, and quickly evolved into a conversation about terms people use when talking about Linked Data, and more generally the Web.
I ended up having a very helpful off-list email exchange [...]

open to view

Thursday, August 13, 2009

I spent an hour checking out the HathiTrust API docs this morning; mainly to see what the similarities and differences are with the as-of-yet undocumented API for Chronicling America. There are quite a few similarities in the general RESTful approach, and the use of Atom, METS and PREMIS in the metadata that is made available. [...]

rest, the semantic web and my feeble brain

Thursday, May 14, 2009

Imagine you were minting close to a million URIs for historic newspaper pages such as:

http://chroniclingamerica.loc.gov/lccn/sn85066387/1898-01-01/ed-1/seq-1/

for pages like:

The web page allows you to zoom in quite close and see lots of detail in the page:

Now lets say I want to describe this Newspaper Page in RDF. I need to decide what subject URI to hang the [...]

freebase and linked-data

Wednesday, October 29, 2008

Ok, this is pretty big news for linked data folks, and for semweb-heads in general. Freebase is now a linked-data target. This is important news because Freebase is an active community of content creators, creating rich data-centric descriptions with a wiki style interface, fancy data loaders, and useful machine APIs.
The web2.0-meets-semweb space is also [...]

iswc2009, DC and vocamp

Monday, September 22, 2008

I just learned from Tom Heath that The International Semantic Web Conference is coming to Washington DC next year. This is pretty cool news to me, since traveling to conferences isn’t always the easiest thing to navigate. Also, Tom suggested that it might be fun to organize a VoCamp around the conference, to provide an [...]

justify my links

Thursday, May 29, 2008

Thanks to a tip from Ian, I’m looking forward to (hopefully) attending the Linked Data Planet conference in New York City as a volunteer. The idea is that I just have to pay for my hotel, and the cost of admission is waived. It seems my travel money is a bit limited at the moment [...]

literals and resources

Wednesday, March 26, 2008

There’s a fascinating modeling discussion going on over on the DC-RDA list about whether RDA properties should reference literals or resources in descriptions. For example when describing an author you could use a literal:

Twain, Mark, 1835-1910

or a resource:

http://lccn.loc.gov/n79021164

There are some shades of gray in between (using blank nodes, auto-generated URIs, typed literals) but that’s the [...]

oai-ore and the shadow web

Friday, February 22, 2008

The OAI-ORE meeting is coming up, and in general I’ve been really impressed with the alpha specs that have come out. It’s not clear that there’s an established vocabulary for talking about aggregated resources on the web, so the Data Model and Vocabulary documents were of particular interest to me.
One thing I didn’t quite understand, [...]

calais and ocr newspaper data

Wednesday, February 13, 2008

Like you I’ve been reading about the new Reuters Calais Web Service. The basic gist is you can send the service text and get back machine readable data about recognized entities (personal names, state/province names, city names, etc). The response format is kind of interesting because it’s RDF that uses a bunch of homespun [...]

following your nose to the web of data

Friday, January 4, 2008

This is a draft of a column that’s slated to be published some time in Information Standards Quarterly. Jay was kind enough to let me post it here in this form before it goes to press. It seems timely to put it out there. Please feel free to leave comments to point out inaccuracies, errors, [...]
