Apple's Core Data

With the release of Tiger, Apple will be making their EOF entity-relationship modelling approach available for use in all OSX apps.

Three data store formats will be available: binary, xml, and sql. This could help a lot with converting and wiring various app data into the greater semantic web. Apple will already be tapping Core Data for searching and sharing in Tiger:

The technically correct way to describe Core Data is as an object-graph management and persistence framework.

In down-to-earth terms, this means that Core Data organizes the application's model layer into a set of defined in-memory data objects. Core Data tracks changes to these objects and can reverse those changes on demand, such as when a user performs an undo command. Then, when it is time to save changes to your application's data, Core Data takes care of archiving the objects to a persistent store.

And, it saves data into regular files that users can manage with the Finder, search with Spotlight, backup to CD, and email to friends, family, and coworkers. Source: CocoaDev Discussion

MT-Redland

Danny, Ian, and others are pointing to Gregory Williams' MT-Redland. I can't wait until I get home to get it running.

Of course, I couldn't wait. I unpacked it at work and looked around. This replaces MT's MySql data store with triples (by way of Redland).

On the front-end, MT-Redland uses the MT plugin API to incorporate any kind of semantic content into blogging. One of the plugins allows ratings to be associated with an entry using RDF Review. There are also plugins / UIs for adding book, document, and event topics.

Using this app is going to save me a lot of time in incorporating the financial data into blogging!
