A JSON list of podcast prefix companies

If you have the URL of a podcast's audio file, this JSON file will help you work out whether there is a podcast prefix company being used for analytics, and be able to link to their privacy policy

For now, the simplest way is to add to the file at src/prefixes.json. Each podcast host may have multiple entries, but the URL patterns should be unique.

Each entry must contain the following properties:

• prefixpattern: a unique string to spot within the audio URL. It may not always be first, when companies chain URLs.

• prefixname: a humanly-readable name of the prefix company

• iab: a boolean showing whether stats from this prefix company are certified IAB v2 compliant

• abilities_stats: a boolean showing whether this prefix company uses its logs to provide stats

• abilities_tracking: a boolean showing whether this prefix company uses its logs to provide tracking and attribution

• abilities_dynamicaudio: a boolean showing whether this prefix company is capable of dynamic content insertion, used for advertising or content.

• prefixurl: a website link (escaped) that links to the homepage of the podcast prefix company.

• prefixprivacyurl: a website link (escaped) that links to the privacy policy of the podcast prefix company.

• notes: freeform detail about how the 'tracking' and 'dynamicaudio' values were decided upon.

Podnews uses this:

$stmt = $db->prepare("SELECT * FROM `podcasts-prefixes` WHERE INSTR(:url,prefixpattern)"); $stmt->execute(array(':url'=>$podcast['audiourl'])); $prefixes = $stmt->fetchAll(PDO::FETCH_ASSOC);

Of note: some podcasts are measured by multiple prefix providers.

Improvements are welcome.
