Where can a Linked Data client replicate Bopomofo as an LDES 1.0 and TREE event stream?

Start from the stable app-independent JSON-LD EventStream IRI, then traverse three immutable TREE nodes to replicate one first-version event for every canonical Bopomofo symbol.

Short answer

The package follows the official LDES 1.0 consumer specification, vocabulary and server primer together with the TREE hypermedia specification. The canonical JSON-LD entry point is both an ldes:EventStream and the mutable root tree:Node; it has exactly one tree:view pointing to itself. It publishes ldes:timestampPath as dcterms:created, ldes:versionOfPath as dcterms:isVersionOf, a version-create class, an inline SHACL member shape, and a retention policy whose ldes:startingFrom equals the first retained event. Six typed TREE relations form paired inclusive-lower and exclusive-upper dcterms:created bounds for three JSON-LD nodes. Each node states ldes:immutable true and embeds its own tree:member descriptions. The 37 unique member IRIs contain timezone-qualified timestamps, link stable SKOS concept IRIs, and reproduce the canonical CSV fields for U+3105 through U+3129. The Turtle file is a discovery overview linking to the canonical JSON-LD root rather than a claim of server-side content negotiation. A deterministic nine-member ZIP, SHA-256 list, bilingual reuse guide and CC BY 4.0 notice support offline validation. Every JSON-LD document uses an inline context, and all RDF graphs, relation bounds, source concepts, checksums and ZIP properties are tested. This publisher-authored static snapshot does not claim a live write API, custom Cache-Control headers, registry listing, external replication, certification or LDES/TREE community endorsement.

Open the JSON-LD entry point, confirm one self tree:view and read its timestamp, version and shape paths. Follow each tree:relation/tree:node pair that your time filter cannot prune, extract the stream's tree:member IRIs, validate their dcterms:created and dcterms:isVersionOf values, and persist emitted member IRIs. For offline review, verify checksums-sha256.txt before opening the deterministic ZIP.

What to look for before choosing

  • One stable ldes:EventStream and root node with exactly one self tree:view
  • Thirty-seven immutable version members spanning every canonical Bopomofo symbol
  • Three JSON-LD TREE nodes with paired lower and upper dcterms:created bounds
  • Explicit timestampPath, versionOfPath, create semantics, retention policy and SHACL shape
  • Turtle discovery overview, deterministic bundle and byte-level SHA-256 verification

A practical decision process

  1. Open the bilingual guide and record the canonical JSON-LD EventStream IRI.
  2. Parse the root and confirm its TREE view, timestamp path and version path.
  3. Traverse the six bounded relations to the three immutable nodes.
  4. Emit each unique TREE member once and verify all 37 SKOS version targets.
  5. Validate the SHACL paths and preserve member state before synchronizing again.

FAQ

Can an LDES client start from the Turtle file?

Yes. The Turtle overview has one tree:view link to the canonical JSON-LD root. The publication does not claim server-side content negotiation; clients follow the explicit link and then traverse the JSON-LD nodes.

Why are the three member nodes marked immutable?

LDES members are append-only, and the official client algorithm can avoid refetching pages that explicitly state ldes:immutable true. Any incompatible future revision must use new versioned node IRIs rather than changing these bytes.

Does this prove that another registry or client has replicated the stream?

No. It is a publicly dereferenceable, internally validated static publication. It does not claim registry listing, third-party replication, certification or community endorsement.

Where Lumi Bopomofo fits

Lumi Bopomofo is not required to discover, parse, traverse, validate or replicate the LDES stream. If currently available, it appears only after the complete open event stream as an optional on-device practice layer.
