Getting to higher MARC branches showed how the RDFS subPropertyOf property can be used to entail, or infer, RDF data triples with a broader semantic or meaning than the original, to “dumb-up” or aggregate data based on level 0 properties. Only the property or predicate part of the triple is different; the subject URI and […]

In the previous blog I discussed Low-hanging MARC fruit in the MARC21 fixed-length data fields 006, 007, and 008. These fields also contain useful data that hangs slightly higher up, but can be reached with a short ladder. The ladder rungs are constructed using the RDF Schema subPropertyOf property. This is an ontological property which […]

It’s been six months since Diane Hillmann, Jon Phipps, and I published a “level 0” set of RDF elements (all properties) and value vocabularies based on the MARC21 format. That was largely a mechanical process, as we created a separate property for every combination of tag, two indicators, and subfield for most (but not yet […]

One continuing theme of the recently concluded DC-2010 is that of the perpetual search for consensus on what the hell DCMI should be doing. I know this continual search for identity is a common phenomenon with this sort of organization, as it is for the human adolescent hovering around the age of 15 years. Like […]

This morning’s highlight was Stu Weibel’s opening keynote address to the assembled conference attendees (yesterday included primarily workshop sessions and tutorials). Stu was asked to talk about DC’s past and future, and he gave many of us food for thought. The first thing he did was typical Stu—he took a photo of the assembled group. […]

One of the things that always happens for me after ALA is a compiling of notes and some reflection on what I saw and learned while in the whirlwind of meetings and activities. This year is no different. There were few real surprises—after all, like most of you I keep in pretty good touch with […]

Corey Harper seems to have started a collection of statements taken out of context, some of which I’ll share here: “If it’s not fish it has to be linked data” –Jennifer Bowen “I’m too far underground to know where I am” –Jon Phipps

Today I participated in a Linked Data Unconference at ALA 2010 in Washington DC, which was remarkably successful. Organized by Corey Harper from NYU and ably moderated by Karen Coyle, about 50 of us held two sets of three hour-long, highly engaging breakout discussions with reports back to the larger group. I participated in a […]

One of my favorite aphorisms is “Time flies, whether you’re having fun or not.” I’m not sure where I heard it, but for sure I’m not creative enough to make it up on my own. The truth of it has been reinforced by the realization that here it is the end of January, post-Boston Midwinter, […]

A few weeks ago I attended the opening of an amber exhibition at our wonderful Museum of the Earth which is only about 6 miles from my house. The exhibit had a little of everything: science, history, geography … and jewelry. I have to admit (and this will surprise no one who knows me) that […]
