To build a music distribution system for CentricBeats, the process works by transforming the user's input into a standardized digital "package" that streaming services can read. This involves a coordinated workflow between your front-end JavaScript, your database, and the final metadata export.

1. The Front-End: Capture and Validation

When an artist uploads a track, JavaScript acts as the "gatekeeper" to ensure the data is perfect before it reaches your server.

• File Analysis: JavaScript libraries can inspect an uploaded file to confirm it is a 16-bit or 24-bit WAV at 44.1kHz.

• Artwork Check: JS verifies the cover art is a square image, ideally 3000 x 3000 pixels, and rejects anything below the 1400 x 1400 pixel minimum.

• Format Enforcement: JavaScript ensures the Release Date follows the YYYY-MM-DD scheme and that the ISRC is exactly 12 alphanumeric characters.

2. The Database: Storing the "Scheme"

Your server saves this validated information into a database structured to mirror the DDEX requirements.

• Mapping Roles: User-friendly terms like "Producer" or "Writer" are converted into standardized DDEX Role Codes (e.g., Composer vs. Lyricist) in your database.

• Identifier Generation: If an artist does not provide their own ISRC or UPC, your system generates these unique codes and stores them with the release.

• Rights Management: The database tracks which Territories (countries) the music is cleared for and records the C-Line (©) and P-Line (℗) copyright details.

3. The Transformation: Generating the DDEX XML

Once the release is approved, your system performs the most critical step: converting the database rows into a DDEX XML file.

• XML Packaging: The system creates a message header with a Message ID and Timestamp.

• Hierarchy Creation: It organizes the metadata into sections for Release Information, Resource Metadata (the audio/art files), and Party Metadata (the contributors).

• Technical Specs: It includes technical tags for Duration, Sample Rate, and Bit Depth so the DSP knows how to process the audio.

4. The Delivery: DSP Submission

Finally, the system bundles the DDEX XML file, the WAV audio, and the Artwork JPG/PNG together.

• Electronic Delivery: This bundle is sent via SFTP or an API directly to platforms like Spotify, Apple Music, or aggregators like DistroKid.

• Reporting: The system waits for an acknowledgment from the recipient to confirm the metadata was successfully ingested.

Would you like me to write a sample MySQL table structure that uses these DDEX-standard fields?
