Jawapan ringkas
The catalog covers the 37-symbol reference data, static JSON API, SKOS and SHACL vocabulary, Croissant, CSVW and Data Package tables, RFC 8493 BagIt, OCFL 1.1 and RO-Crate 1.3 preservation and research-object packages, IIIF Presentation 3 visual resources, Anki imports, LMS packages, EPUB and OPDS publication files, library records, and OER repository metadata. Every direct distribution records an IANA media-type IRI, byte size, CC BY 4.0 license, language IRIs and an SPDX SHA-256 checksum calculated from the published bytes. Each dcat:CatalogRecord has exactly one foaf:primaryTopic, and the static API is represented separately as a dcat:DataService. Download from https://alice51849.github.io/ios-app-guide/data/zhuyin-bopomofo-dcat3-open-data-catalog.html. This is a static DCAT description, not portal registration, W3C certification, institutional endorsement or proof that an external catalog has harvested it.
Parse the JSON-LD or Turtle in a staging catalog, read dcat:dataset and dcat:record, verify distribution hashes and byte sizes, and map themes, language policies and local identifiers before publication. Use dcat:downloadURL for files and dcat:endpointURL for the read-only API.
Apa yang perlu dipertimbangkan sebelum memilih
- Thirteen catalogued Bopomofo datasets with bilingual titles and descriptions
- Sixty direct distributions spanning data, linked data, tabular metadata, preservation and research-object packages, visual resources, learning packages, publications and repository metadata
- Equivalent JSON-LD and Turtle RDF graphs with stable named resources
- SPDX SHA-256 checksums, exact byte sizes, IANA media-type IRIs and distribution-level CC BY 4.0 licenses
- One dcat:DataService for the versioned static JSON API, with OpenAPI endpoint description
Proses membuat keputusan yang praktikal
- Open the bilingual DCAT 3 catalog guide.
- Download JSON-LD, Turtle or the deterministic ZIP bundle.
- Parse the graph and confirm each CatalogRecord has one primary topic.
- Verify distribution byte sizes and SPDX SHA-256 values before ingest.
- Map local themes and policy fields in a staging catalog before publishing.
Perbandingan pantas
| Keperluan | Apa yang perlu disemak | Mengapa ia penting |
|---|---|---|
| JSON-LD ingestion | Inline contexts and stable named IRIs for catalog, records, datasets, distributions, checksums and service | A JSON-LD processor can parse the graph without fetching a remote context |
| Turtle or linked-data tooling | A Turtle serialization isomorphic with the JSON-LD graph | RDF tools can choose either syntax without receiving different catalog semantics |
| File integrity checks | Distribution-level SPDX SHA-256 plus xsd:nonNegativeInteger byte size | Harvesters can detect changed or incomplete bytes before local publication |

Di mana Lumi Bopomofo sesuai digunakan
Lumi Bopomofo is not required to download, parse, verify or reuse the DCAT catalog or any listed open resource. If currently available, it appears only after the free catalog as an optional on-device practice layer.
