XML Bad Practices — Introduction — Robin Berjon

Written by Chris Beer on Tuesday, December 22, 2009

Perhaps this series is of interest as PBCore goes forward

"XML is now over ten years old and can euphemistically be dubbed a success. That being said, I don't believe I need convince readers that not all of its uses have been successful. Over time, many bright minds have attempted to describe how to best make use of it when designing vocabularies, but I believe it is safe to say that those efforts, no matter how excellent, have not been sufficient in ensuring that all applications of XML are produced in an entirely sane manner."

PBCore Recommendation : PBCoreCollection

Written by daniel_jacobson on Tuesday, December 08, 2009

Over the last few months, I have worked with Jack Brighton and Dave Rice to have the NPR API (http://www.npr.org/api) output PBCore as a supported format. In the early stages, we were able to put together a mapping of NPRML (our native XML format) to PBCore. From this mapping, my team and I started conceptualizing how this would work within the framework of the API. This exercise ultimately failed because of a philosophical issue between PBCore and the NPR API.

Some thoughts on future directions of PBCore

Written by Chris Beer on Thursday, November 12, 2009

For the last couple weeks, I've been thinking about some ways PBCore could changes to be easier to use and friendlier. Part of this was spurred by the PBCore 2.0 RFP, but also while I was trying to figure out how to teach PBCore to a workshop introducing XML at AMIA '09. This allowed me to take a step back from my use of PBCore to power digital archives and think about some bigger picture issues. I've been jotting my thoughts down elsewhere, but it would be more helpful to the community to record them here as well.

pbcoreContributor element issue

Written by Jack Brighton on Monday, November 02, 2009

Let's say I'm trying to record contributors to a movie and have a list of actors. In PBCore I can list each name, and record contributorRole as "actor." But there's no way to record what role they played as actor. Seems like a big gap! This could easily be solved in one of two ways:

Add an optional third element inside the pbcoreContributor container to record this. What to call it? Part maybe?

Add an optional attribute to contributorRole, so you can say something like:

    <contributor>Julie Roberts</contributor>
    <contributorRole part="Erin Brockovich">Actor</contributorRole>

Only problem with this is, PBCore doesn't use attributes. So maybe the first way is better:

    <contributor>Julie Roberts</contributor>
    <contributorPart>Erin Brockovich</contributorPart>

Fun new category added to PBCoreresources.org: Change Requests

Written by Jack Brighton on Friday, October 30, 2009

If things appear quite in pbcoreland, that would be only a surface-level view. A lively discussion is taking place, for example, on the American Archive Pilot Project Basecamp site. People are asking questions about why PBCore elements are as they are, how PBCore matches the requirements of their collections and projects, and poking it with sticks in various ways. The AMIA Conference arrives in St. Louis next week, following a year in which many AMIA folks have submerged PBCore in white fire and subzero liquids. Other open source software projects are leveraging PBCore to exchange data and media files between far-flung systems. Lots of us have been throwing tons of actual content against the PBCore wall, and seeing which pieces stick or bounce back.

PBCore 2.0 will be coming, and it needs our help.

So I'm putting out the call (with the encouragement of Paul Burrows) for something we'll categorize on this site as Change Requests. Many suggestions have already been made on vairous listservs and other online spaces, and we'll be looking through those to compile them here. If you have other suggestions for changes to PBCore, you can add them here yourself. (Anyone who is a Member of this site can post to it, and you can sign up on the home page.) Please make sure to assign your entry to the category Change Request. We can then more easily filter these into a pile, and sort them into subcategories as needed.

I'll be an active curator as needed, so just let me know what "as needed" means to you, and let 'er rip.
