This is a page describing "everything" a web-based (media) hosting site could do to integrate CC and CC-related features.

Imitation of Flickr's CC integration is a recommended first pass:

• http://flickr.com/account/prefs/license/ -- user license selection (must be logged in to see)
• http://flickr.com/creativecommons -- CC browse
• http://flickr.com/search/advanced/ -- CC search

Choose license

Default License

There should be a default license to govern all content that is project-wide. For websites, this involves adding a license with proper marking somewhere on the site and using this as the default for all other selections when applicable (feeds, default for user-generated-content, etc). Sites like Technorati have licensed all content on their site under a specific license and note this at the bottom of their website on every page.

Individual Licenses

After a default license is applied on a project, then consider making an atomic approach to licensing where individual pieces of media have licenses applied both with physical marking and in technology, such as in Syndication.

User Preference

Users should also be given the preference to set their default license and/or set the license per media item. And, all technologies should adapt to this user selection as with Syndication. For example, Flickr allows users to select a license for uploaded photos as time of upload, but also have default license which is selected to reduce the amount of work a user must undertake for this task.

User Interface

Default

The default approach for marking a licensed piece of content is demonstrated on our license page.

Dropdown

A drop-down list for selecting licenses seems to be quite effective. See how this is done on Flickr and others sites.

Widget

The CC JsWidget provides an easy way to integrate the license choices provided in the default case above into your site.

API

There should be a licensing API that might be part of a restful api that allows querying of the site, and outputting of possibly Syndication with proper license attribution, etc. There are other ways an API could specify license as well.

Publish License on the Web

Link to License

The best way to show a license use is to link to the full URL back to the CC license. See the license page for how this is done.

Use RDFa

RDFa is RDF in attributes and CC current recommendation for exhibiting semantic relationships for search engines and other machines to understand content relationships. See examples of this on http://labs.creativecommons.org

• See #"More Rights" integration
• Similarly, machine-readable attribution should be included, see examples on ccLabs.

Search

Facilitate search based on license properties, typically:

• Any CC license
• CC licenses that allow remix
• CC licenses that allow commercial use

Examples include engines built into http://search.creativecommons.org

Ideally these search parameters may be set on the URL. See CC search integration for several examples.

Browse

CC Portal (Channel) on Site

Create a channel on your project for all the CC licensed content. Good examples include http://flickr.com/creativecommons and http://jamendo.com/creativecommons/

Limit Browsing to CC Licensed Content

This could be based upon tag, internal marking of licensing, and or any way a project sees fit to limit browsing possibly in connection with #Search.

Feeds

CC annotations

There should be a license for the entire feed as default (if your site uses default licensing) and then a per-item license. If you only have default license for your site, it is recommended to add the license to each item in the feed. See more about how to do this technically on our Syndication page.

Feed URLs Facilitating CC Restrictions

Similar to #Browse, provide a way to limit content in feeds based upon CC Restrictions similar to how its done in #Search.

Embed WebStatement

NOTE: While it is important to embed metadata, it is a much higher priority to #Publish License on the Web and to mark what license you are using using the media you have licensed.

ID3

For MP3s, it is recommended to use the standard ID3 fields at the present time for embedding information about CC licenses for the content. This is the one exception to using XMP, and it is recommended to search file-types that use ID3 for XMP as well.

XMP

We recommend that all use XMP for metadata embedding of CC licenses. This is de-facto metadata standard now with support from Adobe, Microsoft, and more.

Education

While Creative Commons provides the necessary education about how Creative Commons licensing, technology and standards works, there are some key ways to explain Creative Commons on your media hosting site in relationship to your own project goals. Great examples of explaining Creative Commons should be linked to http://creativecommons.org/learnmore with emphasis on our explanatory videos. Also, http://makeinternettv.org/ does a great job of explaining generically how Creative Commons licensing works for media hosting sites. Specifically see their licensing page: http://makeinternettv.org/license/cc.php

See Marking_Works_Technical#Web_Statement.

Re-use tracking

link: search

Reuse external to your repository should link back to the source work hosted by you. You can provide a service to your users by gathering reuse links via link: queries (e.g., via Yahoo! Site Explorer API), Technorati, and others.

Sample Pool API

The Sample Pool API facilitates searching for content to reuse across repositories and notification upon reuse. See ccHost for a sample implementation.

CC+ integration

Use rel="cc:morePermissions" to denote links allowing a user to do more than the CC public license permits, e.g., purchase commercial rights, warranty, purchase media, tickets, patronage... See ccLabs for information and examples and a license generator that will create a more permissions link. See this page for more on the CC+ initiative.
