- The same video can have multiple URLs.
- These URLs can have different tracking parameters, host aliases, or shortened links.
- Your database will store each URL as a separate entry, even if they point to the same video.
To solve this problem, you need to canonicalize your video URLs. This means reducing multiple equivalent representations of a URL to one chosen representative.
Here's how you can do it:
- Normalize the URL string: remove tracking parameters, sort query strings, and lowercase hosts.
- Extract a platform-stable identity from the normalized URL: get the video ID from the URL.
You can use PHP to create a canonicalization pipeline. This pipeline will have two layers:
- String normalization: clean up the URL.
- Identity extraction: get the video ID.
You can use the following PHP classes to achieve this:
- UrlNormalizer: normalizes the URL string.
- VideoIdentity: extracts the video ID from the normalized URL.
You can then use these classes to create a canonical key for each video. This key will be a combination of the platform and video ID.
You can store this key in your database and use it to deduplicate your video URLs. This will improve your data quality and prevent duplicate entries.
