Scrape podcast metadata for archiving

To scrape podcast metadata for archiving, you can extract details like title, author, description, episode list, publish dates, duration, and more using available podcast directories or RSS feeds. Here’s a breakdown of how to do it:

1. Identify the Podcast Source

Use popular podcast platforms like:

• Apple Podcasts

• Spotify

• Google Podcasts

• Pocket Casts

• RSS feeds directly from podcast websites

Best Option for Metadata:
Use the RSS feed, which is designed to contain structured metadata for each episode.

2. Required Metadata to Archive

Typical metadata you might want to scrape:

• Podcast title

• Author

• Description

• Category/Genre

• Language

• Episode title

• Episode description

• Publish date

• Episode duration

• Episode URL/audio file

• Episode number/season

• Explicit content flag

• Cover image

3. How to Scrape Using Python

Option A: Using RSS Feed

Most podcasts offer an RSS feed URL. Example code:

python
CopyEdit
import feedparser

rss_url = 'https://feeds.simplecast.com/54nAGcIl'  # Example RSS feed URL
feed = feedparser.parse(rss_url)

podcast_metadata = {
    'podcast_title': feed.feed.title,
    'author': feed.feed.get('author', 'Unknown'),
    'description': feed.feed.get('description', ''),
    'episodes': []
}

for entry in feed.entries:
    episode = {
        'title': entry.title,
        'description': entry.get('description', ''),
        'published': entry.get('published', ''),
        'duration': entry.get('itunes_duration', ''),
        'audio_url': entry.enclosures[0].href if entry.enclosures else '',
        'episode_number': entry.get('itunes_episode', ''),
        'season': entry.get('itunes_season', ''),
        'explicit': entry.get('itunes_explicit', 'no')
    }
    podcast_metadata['episodes'].append(episode)

print(podcast_metadata)

Option B: Scraping Web Pages (e.g., Apple Podcasts)

Not recommended unless there’s no RSS feed. These sites often change their HTML structure and may block bots.

Use libraries like requests and BeautifulSoup for HTML scraping.

4. Save the Metadata

Save to JSON, CSV, or a database.

python
CopyEdit
import json

with open('podcast_metadata.json', 'w') as f:
    json.dump(podcast_metadata, f, indent=2)

5. Notes on Ethical & Legal Considerations

• Check Terms of Use for the source you’re scraping.

• Use official APIs when possible (e.g., Listen Notes, iTunes Search API).

• Don’t overload servers with rapid or repeated requests.
