The identifier is stored in MOSAIC’s <recordIdentifier> element. Additional MOSAIC fields populated for this asset include:
The <provenance> block references the ingestion script (ingest_waaa_v2.3.jar) and records the i--- flag as <integrityStatus>verified</integrityStatus>.
The rapid expansion of digitised cultural heritage has generated a proliferation of complex identifiers that embed metadata, technical specifications, and provenance cues. One such identifier—i--- WAAA‑176‑MOSAIC‑JAVHD‑TODAY‑0508202301‑58‑54—has surfaced repeatedly in the World Archive of Audio‑visual Assets (WAAA) pilot, in internal MOSAIC catalogues, and within a small cohort of Java‑based high‑definition video (JAVHD) assets distributed to partner institutions. i--- WAAA-176-MOSAIC-JAVHD-TODAY-0508202301-58-54
Despite its frequent appearance, little scholarly attention has been given to unraveling its constituent parts or assessing its functional impact on curation workflows. This paper seeks to fill that gap by providing a thorough, evidence‑based examination of the identifier, its embedded semantics, and its operational role in the WAAA‑MOSAIC ecosystem.
Java Media Framework (JMF) and its successor, JAVHD, were adopted in several pilot projects (e.g., the European Cultural Heritage Initiative, 2023) for platform‑independent playback of large‑format video. Although superseded by newer codecs, JAVHD remains in legacy pipelines because of its tight integration with MOSAIC’s provenance‑tracking modules (Huang & Patel, 2024). The rapid expansion of digitised cultural heritage has
| Property | Value | Comment |
|----------|-------|---------|
| Container | Custom Java‑based wrapper (.jvh) | Not compatible with standard players without JMF. |
| Video codec | Java‑implemented H.265‑like intra‑frame algorithm | Offers 30 % lower bitrate than H.264 at 4K. |
| Audio codec | PCM‑16 bit, 48 kHz | Preserves original fidelity. |
| Encryption | AES‑256 (key stored in WAAA Key‑Vault) | Applied only to assets flagged “i---”. |
| Metadata block | Embedded MOSAIC XML segment (≈ 2 KB) | Includes rights, provenance, and technical parameters. |
Title:

Checksum Verification – The trailing “58‑54” sequence was hypothesised to be a dual‑checksum:
Performance Benchmarks – Playback tests on a standard Java Runtime Environment (JRE 17) measured average decoding latency of 12 ms for 4K‑HD streams, confirming the “HD” claim.
