Pull NIST Reference Datasets (RDS) catalog metadata

Source: R/ingest_forensics.R
morie_ingest_forensics_nist_rds.Rd

The raw reference datasets (CSAFE bullets/cartridges, NSRL hash library, ...) are multi-gigabyte and shipped on dedicated download servers; this function returns only the catalog records so the caller can pick what to download separately.

Usage

morie_ingest_forensics_nist_rds(
  dataset_id = NULL,
  query = NULL,
  max_features = NULL,
  page_size = 50L,
  raw = FALSE,
  timeout = .MORIE_FORENSICS_DEFAULT_TIMEOUT
)

Arguments

dataset_id

Specific NIST RDS / EDI id (e.g. "ark:/88434/mds2-2418"). When set, returns a single-row frame.

query

Free-text search over title / description / keyword. Ignored when dataset_id is set.

max_features

Optional hard cap on returned rows.

page_size

Records per request (default 50).

raw

If TRUE, return the raw catalog JSON columns instead of morie's flattened schema.

timeout

HTTP timeout in seconds.

Value

A base R data.frame.
