I've mentioned both of these projects in numerous discussions. Now they're getting ready for usage I thought I'd make an announcement!
I'll be adding packages to the Orchard Gallery in due course but for now here are links and an overview if you want to get the code.
If anyone wants to know anything or needs any help please ask over at the relevant project site, I'll try to answer all questions as quickly as I can!
The key module here is "Mechanics" which allows you to create any types of many-to-many relationships between content items, entirely from the admin UI. You can completely customize how those relationships are both displayed and edited. You can
even make related items display in different zones using the PaperclipsPart. See the
Mechanics documentation for an example of how to build your content items and connectors.
There are some other modules which at the moment don't do very much but will eventually provide per-item permissions (much requested, and it's nearly ready), and drag-and-drop and AJAX features (which are far from ready!)
This is intended as a huge extension to Orchard's media capabilities, allowing you all kinds of ways to handle and display video, audio, image and other types of media - whether uploaded, or linked from external sites. It converts media files into
actual content items; so they can have their own display pages with any parts you'd like to add on (such as comments, tags, star ratings, anything), and you can easily build things like galleries using Orchard's built-in Lists feature. Or you
can combine this with Mechanics to build galleries and playlists and circumvent the limitations of the Lists feature (i.e. you could have the same item in several different categories, and when displaying you'll get the content item rendered, not just the
list children). There will be an additional module to provide this integration.
It's been active for a while but I've now produced a FlowPlayer integration so you can play most types of media in your website.
