A quick reminder for myself. There is more to metadata than can be described in XML syntax. XML is just text. Text isn’t always the best way of describing something.
Metadata != XML
Metadata > XML
I’m hoping in the next version of the software-formerly-known-as-CAREO that we can get away from this “XML Metadata is the centre of the universe” philosophy. King has demonstrated some freaking amazing things he’s planning to do with metadata/searching/discovery, some of which have nothing to do with text. Hence, they have nothing to do with XML…
Here’s a quick link to a discussion of PHP vs. Java. Sure, that’s much like a discussion of Coke vs. Pepsi, or Mr. T vs. Hulk Hogan, but some interesting points are raised. Note, though, that Raible is a hard-core Java guy, but many of the comments come from hard-core PHP folks.
David Wiley talks about something called the “Reusability Paradox” of learning objects. It’s one of the fundamental issues in dealing with learning objects, and basically boils down to this (grossly oversimplified Coles Notes version of Wiley’s paper):
“If a learning object is useful in a particular context, by definition it is not reusable in a different context. If a learning object is reusable in many contexts, it isn’t particularly useful in any.”
Not rocket surgery, but it’s a tough problem to solve. The exciting thing (for me, anyway) about some of the projects we’re getting involved with at the Learning Commons, is that we’re finally starting to attempt to address this fundamental paradox. How can you have learning objects that are usable and reusable? We’re looking at ways to assemble content from lesser bits, building context along the way. We’re looking at dynamic assemblies of learning objects with varying degrees of contextualization, where the assembly itself provides the context to make it usable in a particular setting, while letting the lesser components of the thing remain reusable in other contexts…
Stay tuned, folks. This is going to be a fun ride!
I just whipped up a brain-dead simple bookmarklet to check Technorati’s link cosmos for the currently viewed web page. Just drag the link below into your bookmarks or toolbar or whatever, and whenever you click it, you should get the Technorati report on who’s linking to that page.
No warrantee, express nor implied. Use at your own risk. If it nukes your system, you should be using a better OS, and it’s not my fault… 😉
UPDATE: It turns out that RTFM applies to me as well… Technorati already offers a version of a bookmarklet that does the exact same thing… Doh. Oh, well… My intension was good, even if I apparently can’t read… Here’s the official script.
Well, you’re probably not, but if you know someone who is, they might be thankful for this page, containing what appears to be a pretty comprehensive list of RSS readers for a whole lotta platforms.
