Where can a digital repository download an OCFL 1.1 object for Bopomofo data?
Use the open OCFL 1.1 object for a transparent, version-aware preservation copy of the complete 37-symbol Bopomofo dataset and its standards metadata.
짧은 답변
The deterministic ZIP extracts to one OCFL Object root. Its exact 0=ocfl_object_1.1 Namaste file declares OCFL 1.1, while the object-root inventory.json and inventory.json.sha512 files are byte-identical to those in the head-version directory. The inventory identifies the object with a stable URI, uses SHA-512 for content addressing, maps physical version content paths in its manifest, and maps content digests to ten portable logical paths in the head state. A complete SHA-256 fixity block independently covers every stored content file. The logical state preserves the canonical 37-row UTF-8 CSV, equivalent JSON Lines, W3C CSVW metadata, MLCommons Croissant 1.1 metadata, the SKOS vocabulary in JSON-LD, Turtle and N-Triples, SHACL shapes, a validation guide and the CC BY 4.0 notice. The extracted object validates with ocfl-py 2.1.0. OCFL specifies an object-at-rest filesystem layout, not a ZIP transfer serialization or OCFL-specific media type, so the download uses generic application/zip with a separate outer SHA-256. This is one OCFL Object, not an OCFL Storage Root, repository service, institutional endorsement or proof of ingest.
Download the ZIP and checksum into the same directory, verify the outer SHA-256, extract the single object root, then run ocfl-validate.py against that directory with ocfl-py 2.1.0. Inspect the inventory id, head, manifest, version state and local rights policy before repository ingest.

|---|---|---|
| Transparent object identification | The root contains the exact 0=ocfl_object_1.1 Namaste declaration | Humans and tools can identify the extracted directory without proprietary software |
| Version and path reconstruction | The inventory separates physical manifest paths from logical state paths | A repository can rebuild the head state while retaining immutable version content |
| Independent byte verification | SHA-512 covers content addressing and SHA-256 fixity covers every physical content path | An OCFL validator can verify inventories, sidecars, state mappings and stored bytes |
Sources and resources
자주 묻는 질문
Is the ZIP itself an OCFL-defined serialization?
No. OCFL 1.1 defines the object-at-rest and storage-root filesystem layouts, not a transfer archive or OCFL-specific media type. The download uses a generic application/zip wrapper and publishes a separate checksum for those ZIP bytes.
Is this download a complete OCFL Storage Root?
No. It is one independently valid OCFL Object with an object declaration. A repository may place it under a separately declared OCFL Storage Root using its own deterministic storage layout.
How does the object preserve future changes?
The generator compares the current logical state with the published head. If source bytes or logical paths change, it appends a new forward-delta version, retains prior version directories and reuses existing content digests instead of rewriting history.
Lumi Bopomofo가 적합한 경우
Lumi Bopomofo is not required to download, validate, preserve or reconstruct the OCFL object. If currently available, it appears only after the open repository resource as an optional on-device practice layer.
