The Powerhouse Museum announced that its collection document had been released under Creative Commons licenses. Factual data about its collection objects are available under CC BY-SA and museum-specific notes are available under a CC BY-NC. (Thanks to Jessica Coates.)

Secondly it means that anyone, commercial or non-commercial can now copy, scrape or harvest our descriptive, temporal and geospatial data, and object dimensions for a wide range of new uses. This could be building a timeline, a map, or a visualisation of our collection mixed with other data. It could be an online publication, a printed text book, or it could be just to improve Wikipedia articles. It can also now be added to Freebase and other online datastores, and incorporated into data services for mobile devices and so much more. ...
Thirdly, we’ve applied an attribution, non-commercial license to object provenance largely to allow broad educational and non-commercial repurposing but not to sanction commercial exploitation of what is usually quite specific material to our Museum (why we collected it etc). ...
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
