Licensed Content Discovery
Not all feeds include license metadata. Heuristics for discovering licensed content. Perhaps useful in particular for aggregators:
- IF feed item contains license reference or feed contains top level license reference
- THEN content in feed (including images and enclosures) probably licensed
- Crawl feed item URLs.
- IF license found for feed item URL (e.g., rel="license")
- THEN content at feed item URL probably licensed
- IF license metadata found specifically for media (e.g., about an image or video URL)
-
- THEN that media is probably licensed
-
- IF license found for feed item URL (e.g., rel="license")
- Download content referred to (e.g., in enclosure)
- IF content contains reference to metadata on the web that says content is licensed, content is probably licensed (see Embedded Metadata
This is obviously just a sketch. Aggregators may wish to use different heuristics for different feeds. See Content Curators for some sites with feeds of CC licensed content.
