Maplestar Compilation REPACK — Reference Survey

Summary

• Maplestar Compilation REPACK is a repackaged distribution of the Maplestar compilation collection (audio, video, and/or multimedia assets) redistributed with standardized metadata, codecs, and filesystem layout for easier archival, playback, or archival ingestion. This survey treats the REPACK as a distinct artifact derived from an original Maplestar release and focuses on provenance, structure, technical specifications, legal considerations, quality assurance, and recommended archival practices.

1. Provenance and Versioning

• Origin: identify the upstream Maplestar Compilation (original release date, label/publisher, edition identifiers). The REPACK is typically produced downstream by archivists, collection maintainers, or community repack teams.
• Repack identifier: include a stable name, semantic version (or build tag), build date (UTC), checksum manifest (SHA-256 for each file), and signer/packer identity where applicable.
• Change log: document differences from upstream (file renames, format conversions, edits/trims, metadata normalization, gap fixes). Provide explicit rationales for each modification.

2. Legal and Rights Considerations

• Rights inventory: itemize claimed rights for each track and visual—copyright owner, licensing terms, public-domain determinations.
• Redistribution risk: evaluate whether re-encoding, bundling, or file renaming affects fair-use or license terms; flag any tracks with ambiguous or restricted clearance.
• Takedown / DMCA: recommend maintaining provenance records and contact points to remediate copyright claims.

3. Packaging & Filesystem Layout

• Top-level structure (recommendation):
  • /MAPLESTAR-REPACK__/
    • /docs/ — legal.txt, changelog.txt, provenance.txt, checksums.txt (SHA-256)
    • /meta/ — per-release metadata (JSON-LD), catalog.xml, credits.txt
    • /audio/ — lossless (FLAC) and lossy (AAC/MP3) subfolders, with one canonical format per track
    • /video/ — Matroska (.mkv) or MP4 with normative codec choices
    • /images/ — cover art, booklets, scans (TIFF archival + JPEG derivatives)
    • /scripts/ — processing scripts used to create the repack (FFmpeg command lines, tagging commands)
    • /checksums/ — manifests for each directory
• File naming: adopt an unambiguous schema: Artist — Album — TrackNum — TrackTitle.ext; normalize Unicode to NFC, remove control characters, and escape filesystem-reserved characters.

4. Metadata Model

• Core metadata fields:
  • release_id, title, artist, album_artist, track_number, track_title, duration_seconds, bitrate, sample_rate, channels, codec, file_size_bytes, checksum_sha256, language, genre, release_date (ISO 8601), publisher, source_medium, capture_date, location (if relevant), contributors (composer, arranger, performers), ISRC/UPC if available, rights_statement.
• Format: provide both a machine-readable manifest (JSON-LD or MusicBrainz-style XML) and a human-readable credits file.
• Controlled vocabularies: use established ontologies/taxonomies (Dublin Core, MusicBrainz, schema.org/musicRecording) for interoperability.

5. Audio & Video Technical Specifications

• Preservation masters:
  • Audio: store lossless FLAC level 8 (or WAV/PCM for bit-perfect needs) with original bit depth and sample rate preserved (recommend storing at original sample rates; common: 44.1 kHz/16-bit, 48 kHz/24-bit). Include embedded cue sheets where applicable.
  • Video: store Matroska (.mkv) with lossless or visually lossless codecs (FFV1 for preservation video; include original raw where available). Keep subtitles/captions as separate timed-text files (WebVTT or SRT) and embed where format supports it.
• Access derivatives:
  • Audio: 320 kbps VBR MP3 or 256 kbps AAC-LC for distribution; produce normalized loudness-compliant files (target -14 LUFS integrated for modern streaming compatibility) but preserve originals untouched in /audio/preservation/.
  • Video: H.264/AVC or H.265/HEVC MP4/MKV for distribution with reasonable CRF (e.g., CRF 18–23 depending on source), preserving aspect ratio and frame rate.
• Checksums: SHA-256 for all files; provide a signed checksum manifest.

6. Quality Assurance & Validation

• Automated checks:
  • Verify checksums (post-build).
  • Validate metadata against schema (JSON Schema for JSON-LD).
  • Confirm codec/container compliance (ffprobe/mediainfo reports).
  • Validate audio integrity (check for clipping, silence sections, out-of-range samples).
  • Validate video frame continuity and timecode consistency.
• Manual checks:
  • Spot-check tracks for encoding artifacts, sync issues, and correct trimming.
  • Verify proper cover art and booklet scans match contents.
• Issue tracking: maintain an issues.md listing known problems and planned fixes.

7. Archival Best Practices

• Redundancy: maintain at least three copies in geographically separate locations; use different storage media types (object store, LTO tape, local disk).
• Fixity: schedule periodic re-checking of checksums (e.g., quarterly for active collections).
• Documentation: include creation environment, tools (with exact versions), and command lines in /scripts/.
• Emulation and playable derivatives: provide both preservation and access versions; document required decoders and player recommendations.
• Rights & access controls: separate preservation copies (restricted) from public access derivatives when rights are limited.

8. Interoperability & Cataloging

• Crosswalks: provide mappings to MusicBrainz, Discogs, and library MARC or BIBFRAME records where helpful.
• Identifiers: mint persistent identifiers for the repack (e.g., ARK, DOI) for citation and linking.
• Harvesting: expose metadata via OAI-PMH or a static catalog JSON-LD endpoint to enable discovery.

9. Reproducibility & Build Transparency

• Reproducible build: store exact FFmpeg/sox/convert commands and environment (OS, tool versions, locale) so third parties can reproduce the repack.
• Build manifest fields: builder_name, builder_contact (or team handle), timestamp_utc, build_runner_sha256, source_release_checksums, transformation_steps[] (ordered list).
• Provide a cryptographic signature (GPG) of the manifest and changelog.

10. Security and Privacy Notes

• Strip embedded personal data from files (e.g., GPS in images, producer notes with personal info).
• Redact or flag content that may implicate privacy or sensitive personal data; document any redactions in provenance.txt.

11. Suggested File- and Release-Level Checklist (Minimal)

• [ ] Source release identification and checksum
• [ ] Repack version tag and build date
• [ ] Preservation masters stored (lossless)
• [ ] Access derivatives produced
• [ ] Metadata manifest (JSON-LD) created and validated
• [ ] Checksum manifests (SHA-256) generated and signed
• [ ] Scripts and tool versions archived
• [ ] QA automated and manual checks recorded
• [ ] Legal/rights inventory included
• [ ] Redaction/privacy review completed

12. Citations and Further Research

• For production and archival tools, consult authoritative docs: FFmpeg, FLAC, Matroska, FFV1 preservation recommendations, and ISO standards for digital preservation (OAIS model). Track any rights/policy updates relevant to the release jurisdiction.

Notes and assumptions

• This survey treats the REPACK as a community/archive-produced distribution built from a known upstream Maplestar Compilation; where the real-world artifact differs, apply the same framework but substitute actual identifiers, dates, and checksums.
• All technical recommendations favor preservation best practices while providing practical access-level derivatives.

If you want, I can: (a) produce a concrete file layout and sample JSON-LD manifest for a specific Maplestar Compilation (provide the release name/date), or (b) generate reproducible FFmpeg/FFV1 commands and a signed checksum manifest template.
