Overview

ISO 20104:2015 - Producer‑Archive Interface Specification (PAIS) defines a standardized method to describe, package and transfer digital space data from a Producer to an Archive. The standard prescribes an abstract syntax and an XML implementation for Submission Information Packages (SIPs) to support reliable transfer, automated validation and archive ingestion. ISO 20104:2015 is the international adoption of CCSDS 651.1-B-1 and is intended to work within the OAIS framework and the PAIMAS methodology.

Key topics and technical requirements

• Formal definition of digital objects: provides structured descriptors to formally define what the Producer will deliver (e.g., transferObjectTypeDescriptor, collectionDescriptor).
• SIP model and constraints: defines the abstract SIP container, transfer object groups, data object containers and rules for SIP sequencing and constraints (sipConstraints).
• XML implementation using XFDU: supplies a concrete mapping of the abstract SIP into an XML Formatted Data Unit (XFDU) manifest and normative PAIS XML schemas for interoperability.
• Transfer and validation support: targets automation of the Transfer and Validation phases of PAIMAS, enabling programmatic validation of SIP contents against agreed descriptors.
• Management and governance: includes annexes and guidance for ID management, SIP→XFDU mapping examples, and informative notes on security and patent considerations.
• Conformance and extensibility: supports specialization of descriptor models to meet mission-specific needs while remaining compatible with PAIMAS and OAIS principles.

Applications and who uses it

ISO 20104:2015 is used by organizations involved in space data lifecycle management, including:

• Mission data producers (spacecraft instrument teams, mission operations) - to create machine‑readable, validated SIPs for archival submission.
• Archive managers and data curators - to define ingest rules, automate validation and ensure long‑term preservation compliance.
• Systems and software engineers - to implement SIP generation, XFDU manifest creation, automated transfer workflows, and ingest pipelines.
• Standards and interoperability teams - to align national or agency procedures with OAIS and CCSDS/ISO best practices.

Practical benefits include improved interoperability, reduced manual ingest effort, reproducible validation, and clearer agreements between producers and archives.
