ISO 14961:2002 specifies the requirements for a parameter value language (PVL) specification for space data and information transfer systems. It establishes a standard keyword value type language for naming and expressing data values and provides an overview and formal syntax specification of the PVL. Two versions of PVL are defined, the basic version (CCSD0006) and an extended character set version (CCSD0008). The specifications in this ISO 14961:2002 are applicable to all space-related science and engineering data exchanges where a keyword value language is desired.

Overview

ISO 14961:2002 - "Space data and information transfer systems - Parameter value language specification" defines the Parameter Value Language (PVL) used for space data and metadata exchange. Adopted from CCSDS 641.0-B.2 (CCSD0006/CCSD0008), the standard specifies a human‑readable, machine‑processable keyword–value language and provides an overview plus a formal syntax. Two PVL variants are defined: the basic CCSD0006 form and an extended character‑set version (CCSD0008) to support accented characters. ISO 14961:2002 applies to space‑related science and engineering data exchanges wherever a keyword value language is desired.

Key Topics

Language purpose: Standardizes naming and expression of parameter values for interoperable metadata and data files.

Character sets: Defines acceptable character sets (basic and extended) and references ISO 8859‑1 where applicable.

Syntax elements: Covers assignment statements, simple and complex values, sets, sequences, date/time formats, units expressions, aggregation blocks, and end statements.

Formal specification: Includes a formal grammar, reserved keywords, and syntax diagrams to ensure consistent implementation.

Constraints & conformance: Specifies constraints to preserve information and conformance rules for implementations and derived Agency standards.

Interoperability: Aligns with ASN.1 references (ISO/IEC 8824‑1) and CCSDS document management to promote coherent agency implementations.

Applications

Who uses ISO 14961:2002 (PVL) and where:

Space agencies & mission teams - to standardize metadata in telemetry, science products, mission planning files, and command sequences.

Instrument and payload developers - to produce readable, machine‑parsable parameter files for instrument configuration and data labeling.

Data centers & archives - for consistent metadata exchange, ingestion, and long‑term preservation of space science data.

Ground segment software & tool vendors - to implement PVL parsers, validators, and converters for data pipelines.

Standards bodies & systems integrators - when deriving Agency standards or integrating multi‑agency data products.

Practical benefits include improved interoperability across missions, simplified parsing of metadata, clearer human inspection of parameter files, and reduced ambiguity in cross‑agency data exchanges.
