Yet another new thing to learn about?
This was posted to the DIGLIB list on May 20, as part of a call for papers.
Semantic transportation data models
An underpinning of any effort to share data is getting agreement on the exact meaning of individual data elements and their relationships. This activity occurs within individual transportation agencies - for example, as part of a data warehousing effort; and in the context of larger data standards setting and data exchange efforts. Precise documentation of meaning is essential for data sharing - it allows a potential data user to determine the suitability of a data set, and it provides the basis for translation across different data elements.
With the emergence of the semantic web, progress is being made in many domains on development of semantic data models or ontologies - using the W3C Resource description Framework (RDF) language, the Ontology Web Language (OWL), or ISO 13250-1 Topic Maps. These are precise specifications of information elements that can be used to improve "findability" on the web and to support intelligent web services.

Open Source aDORe DIDLTools 1.0 software
JB sent this to me. Could be useful for UBdigit info.
Los Alamos, New Mexico, USA, May 17, 2006 ? The LANL Digital Library Research and Prototyping Team & Ghent University Library are pleased to announce the formal release of their DIDLTools software.
The aDORe DIDLTools is a Java toolkit for the construction, validation, serialization and de-serialization of the MPEG-21 DID data model. DID, the MPEG-21 Digital Item Declaration, provides an abstract model for the representation of digital items, whereas DIDL, the MPEG-21 Digital Item Declaration Language specifies how to serialize the model in XML. The API provided by the aDORe DIDLTools allows for the construction of customized DIDL XML documents, as well as provides flexible and extensible serialization methods.
This distribution includes a comprehensive tutorial detailing the steps necessary to model and create a DIDL using the DID-API.
The DIDLTools 1.0 software was developed by the LANL Digital Library Research & Prototyping Team, in partnership with Ghent University.
This software may be used without charge in accord with the terms of the GNU Lesser General Public License (LGPL) .
Further context for the aDORe DIDLTools software is provided in the papers:

This is the organic farm co-op and Chris and Quinn Ankrum belong to, and that I want to join. I think we're going to. How fun to get a bag of produce and figuring out what to do with it.
Update:
We did join this last year, and we were very, very happy with it. We've joined again this year, and I just sent our preferred pick-up dates to our coordinator. The first delivery date is June 23rd. Woohoo!!!

Organic and Frugal?
Organic and Frugal?
Can you buy organic foods and still be frugal?
There are a lot of other links to both organic things and frugal things. Ah, two things I'm striving for, in one neat package!

This is very interesting. I've been thinking more and more lately about what I eat, what my family eats, what I'm teaching my sons. The usual things parents live with, I'm sure. The conversation about eating meat that we had at our last Third Thursday dinner kind of sparked the thinking, I think. I mean, we can afford to not eat mindlessly, so shouldn't we do our part and support organic farming, both for the sake of the farmers, the animals, and ourselves?
Also, there was the story on NPR recently about the neurologist who's really hard on the diet. (What's Triggering Your Migraine?) I keep thinking about that -- should I just stop being a baby about it and embrace the list of dietary triggers? Or, rather, ban the triggers from my life? Hard to do -- coffee, iced tea, cola, chocolate, restaurant food, avocados........... It's tough. I love food.
I'm going to add some links re getting organic meats.
