Where can a digital repository download a METS 2.0 and PREMIS 3.0 package for Bopomofo data?
Use the app-independent transfer package to stage all 37 Bopomofo symbols in a digital repository with a METS 2.0 inventory and structure map plus PREMIS 3.0 preservation metadata.
Câu trả lời ngắn gọn
The deterministic ZIP contains ten members: mets.xml, premis.xml, a bilingual README, a CC BY 4.0 attribution file, five reusable data files and checksums-sha256.txt. METS fileSec inventories seven preserved files by relative path, IANA media type, byte size and SHA-256, while its logical structMap groups data and documentation and points to every file exactly once. A METS 2.0 mdRef links the complete external PREMIS record without using XLink, which METS 2 removed. PREMIS records seven File Objects with matching original names, formats, sizes and fixity; one successful metadata-creation Event; publisher and generator Agents; and one CC BY 4.0 Rights statement linking every Object. Both XML records validate ngoại tuyến against byte-pinned official XSD snapshots from immutable public source commits. The bundle also checks all paths, digests, 37 CSV rows, 37 JSON Lines records, ZIP order, fixed timestamps and file modes. The ZIP is a deterministic transfer wrapper, not a METS-defined archive format. The package has no DOI and does not claim repository registration, external ingest, third-party certification, institutional endorsement or a digital signature.
Download the ZIP and checksums-sha256.txt, verify the outer ZIP digest, extract without changing relative paths, then validate mets.xml and premis.xml against the cited official XSD versions. Confirm that all seven METS file entries, seven PREMIS File Objects, Event links and Rights links match the extracted bytes before repository ingest.

So sánh nhanh
| Need | Những điều cần kiểm tra | Vì sao điều này quan trọng |
|---|---|---|
| Repository inventory and structure | METS 2.0 fileSec inventories seven files and structMap points to every file exactly once | Repository tooling can discover payload and documentation roles without guessing from filenames |
| Preservation provenance and rights | PREMIS 3.0 links seven File Objects to one Event, two Agents and one Rights statement | Fixity, creation provenance and CC BY 4.0 permissions remain explicit at transfer |
| Byte-level verification | METS and PREMIS values match local paths, media types, byte sizes and SHA-256 digests | A repository can reject an incomplete or altered payload before ingest |

FAQ
Does METS embed the PREMIS record?
No. mets.xml uses a METS 2.0 mdRef with LOCREF=premis.xml, the PREMIS 3.0 version, media type, byte size and SHA-256. Both files remain beside each other in the extracted package.
Is the ZIP a METS-defined archive format?
No. METS describes the package inventory and structure, but does not define this ZIP serialization. The ZIP is only a deterministic transfer wrapper with a published outer SHA-256.
Does schema validation prove repository ingest or authenticity?
No. XSD validation and checksums establish structure and fixity only. They do not prove external ingest, institutional endorsement, third-party certification, authenticity or a digital signature.
Nơi Lumi Bopomofo phù hợp
Lumi Bopomofo is not required to download, validate, ingest or reuse any file in this METS and PREMIS package. If currently available, it appears only after the complete preservation resource as an optional on-device practice layer.
