This document discusses using WordPress for a static collection of expert-selected open educational resources (OERs) and a Bayesian feed filter to automatically select resources for a dynamic OER collection. It notes that WordPress metadata is typically about the post rather than the described resource, and asks how to override this. It also discusses challenges around dynamic collection, such as automatic selection of resources and ensuring enough metadata is available for browsing and filtering.

3. Static collection
Expert selected resources, described in
WordPress posts
l
WordPress provides web presence for
description, preview, RSS, possibly other
metadata
l
…. but ....
l
default is for WordPress metadata to be
about the post, how to over-ride this so that,
e.g., RSS info is about the resource
described?

4. Dynamic collection
Selected by Bayesian feed filter, presented by
Waypoint
l
Bayesian filtering is similar to email spam
filters
l
Static collection provides the material needed
to train the filter
l
Waypoint to categories and display dynamic
collection

WordPress for static collection, plugins and
themes that might help, esp. with
representing resource in metadata
l
Challenges of dynamic collection, esp.
automatic selection, and getting enough(?)
metadata for browsing and filtering
