Dataset
BIG292
OpenDeco does not hold BIG292. No copy has been located, requested, received, hashed or parsed, and no licence or terms of use have been read or stored. This record carries the absence in the structure a held dataset would use.
RestrictedThis dataset is not publicly downloadable.
Overview
This is an acquisition record in the candidate state of spec 25. It exists so that the absence of BIG292 is written down in the same shape a held dataset would use, with a typed reason attached to each missing field.
Everything this repository asserts about BIG292 comes from the specification. Section 24 describes it as an important historical human decompression dataset and a strong initial corpus that is neither the whole benchmark nor independent validation for every model. Section 88 schedules its ingestion only where access permits.

Source and citation
Recording a citation before the artifact is in hand risks citing a different compilation from the one that is eventually ingested. So this field stays empty until an artifact arrives.
- Exact source
- Not yet obtainedThe specification names the dataset. It names no holder, and no holder has been contacted from this repository.
- Accession reference
- Not yet obtainedNo accession or correspondence identifies a specific copy.
- Acquisition method
- Not yet obtainedNo method may be assumed from the fact that a dataset is widely cited.
- Retrieval date
- Not applicable at this stageA date is recorded at the moment of transfer and is never inferred from a file timestamp.
- Citation
- Not yet obtainedNo citation has been established for the artifact OpenDeco would actually receive.
Population and exposures
Unknown to OpenDeco
Population, exposure count, exposure type and collection period all describe an artifact that OpenDeco has never seen. Writing a plausible number here would be indistinguishable from a measured one.
Outcomes
Unknown to OpenDeco
Outcome definitions, diagnostic criteria and case counts are properties of the source. None has been read.
Variables and units
ADR-0007 fixes the canonical representation for any dataset OpenDeco ingests: ambient pressure in pascals, time in seconds, gas content as a fraction of one, and depth in metres of seawater as a derived display view carrying its named conversion. Those rules apply to BIG292 on the day it arrives.
Not applicable at this stage
No variable list exists, because no file has been parsed.
Missingness
Not applicable at this stage
Missingness is measured over parsed records. None exists.
Access and licence
Spec 116 forbids inferring redistribution permission from the fact that a file was downloadable. A widely cited dataset is not thereby a redistributable one, and OpenDeco records the terms it has read.
- Data classification
- RESTRICTED
- Access type
- Not yet obtainedThe five access types of spec 116 are assigned from the terms, and no terms have been read.
- Licence
- Not yet obtainedNo licence text has been stored or hashed.
- Redistribution
- Not permitted from this site
Model-development history
The model and dataset relationship registry of spec 191 holds no entry for BIG292, because no BIG292 dataset version exists for a model version to be related to. Every model version in the registry therefore carries the lineage flag unknown, and unknown is never read as independence.
- Model registryEvery record carries its BIG292 lineage flag.
OpenDeco normalization
Not applicable at this stage
No parser has been written for BIG292, because no file from it has been seen. A parser written now would be designed against a description of a format instead of the format itself.
Quality flags
Not applicable at this stage
The fifteen gates of spec 113 run over a normalised representation. None exists for this record.
Content addressing
No digest exists for this record. A dataset version carries a source checksum and a normalised checksum once bytes have arrived and been parsed.
