The "ApprovedRevs" extension is the feature on OpenEI that allows crowd-sourced data to be quality-controlled (approved) in a formal fashion. The incentive & policy (including EZFeed data) and utility rate sections use this feature.
Using specially formatted Ask queries, we can create RSS feeds of the latest updated data in any particular category on OpenEI. Here is an example of the EZFeed data update feed. But what if you want to know more about entries that are not yet approved? Check out this page to see pages whose approved revision is not their latest. While it is not filterable by category, it is easy to call out the utility rates (Data:... pages) from the other pages, which are likely incentive & policy data.
We are looking to improve the ApprovedRevs extension in several ways. One is that the API and Ask queries are exporting data that may or may not be approved, and it doesn't tell you which is the case as the actual content page on OpenEI tells you. We are working on a way to avoid any unapproved data from being exported in Ask queries, APIs and even RDF data for categories that have the additional quality control from the Approved Revisions extension.
