xWiki for AI Act Compliance

The European Union's Artificial Intelligence Act represents the world's first comprehensive legal framework for AI regulation, introducing documentation and transparency obligations that will reshape how organisations develop, deploy, and monitor AI systems. For providers and deployers of high-risk AI systems, the Act's technical documentation requirements are extensive, demanding detailed records of system design, training data, risk assessments, and post-market performance. xWiki provides the structured, version-controlled documentation environment that organisations need to demonstrate AI Act compliance in a manner that is both thorough and sustainable over the long term.

Overview of the EU AI Act

The AI Act classifies AI systems into risk categories: unacceptable risk (prohibited), high risk (heavily regulated), limited risk (transparency obligations), and minimal risk (no specific requirements). The most significant documentation burden falls on providers and deployers of high-risk AI systems, which include those used in critical infrastructure, education, employment, law enforcement, and essential services. These organisations must maintain technical documentation that enables conformity assessment, implement quality management systems, and conduct ongoing post-market monitoring. The regulation's phased implementation timeline means that organisations should be building their documentation frameworks now, even before all provisions become enforceable.

High-Risk AI System Documentation Requirements

Article 11 of the AI Act requires providers of high-risk AI systems to draw up technical documentation before the system is placed on the market, and to keep it up to date throughout the system's lifecycle. This documentation must be sufficiently detailed to allow authorities to assess the system's compliance. xWiki's wiki-native approach, where every page is versioned and every change is traceable, aligns perfectly with this requirement. A dedicated AI System Documentation space in xWiki can serve as the living technical file for each AI system, evolving as the system itself is developed, tested, and updated.

Risk Assessment Documentation

Providers of high-risk AI systems must identify and analyse known and reasonably foreseeable risks, estimate them, and evaluate them against appropriate risk acceptance criteria. The risk assessment must be documented and updated throughout the system's lifecycle. In xWiki, risk assessments can be maintained as structured pages with fields for risk description, likelihood, severity, affected populations, mitigation measures, and residual risk levels. As the AI system evolves and new risks emerge, the risk assessment pages are updated in place, preserving the full history of how risk understanding has developed over time.

Data Governance Records

The AI Act places particular emphasis on the quality of training, validation, and testing datasets used in high-risk AI systems. Providers must document the data collection processes, data preparation operations, assumptions about what the data measures, potential biases, and gaps identified. xWiki can host a comprehensive data governance register where each dataset used by an AI system has its own page documenting its provenance, composition, preprocessing steps, and known limitations. Linking dataset pages to the corresponding AI system documentation ensures traceability from model behaviour back to training data characteristics.

Technical Documentation per Annex IV

Annex IV of the AI Act specifies the minimum content of technical documentation for high-risk AI systems. It covers a general description of the system, detailed design and development information, monitoring and control mechanisms, risk management measures, and a description of changes made throughout the lifecycle. xWiki's hierarchical page structure maps directly onto Annex IV's sections. Each section becomes a page or page group within the AI system's documentation space, and cross-links between sections ensure that related information is always connected. Templates based on Annex IV's structure can be created once and reused across multiple AI systems, promoting consistency while allowing system-specific detail.

Conformity Assessment Evidence

Before a high-risk AI system can be placed on the market, the provider must undergo a conformity assessment to verify compliance with the Act's requirements. Depending on the type of system, this may be a self-assessment or require the involvement of a notified body. In either case, the documentation assembled in xWiki serves as the primary evidence base. Organising evidence by Annex IV section, tagging pages with the relevant requirements, and maintaining a conformity checklist page that links to all supporting documentation allows providers to present a coherent, navigable evidence package to assessors.

Post-Market Monitoring Documentation

Article 72 requires providers to establish and document a post-market monitoring system proportionate to the nature of the AI system and its risks. This includes procedures for collecting and analysing data on system performance, detecting risks, and triggering corrective actions. xWiki can host the post-market monitoring plan, periodic performance reports, incident logs, and records of corrective actions taken. Each incident report can be logged as a structured child page with fields for incident classification, root cause analysis, affected users, and remediation steps, creating a searchable, auditable incident history.

Using xWiki Structured Data for an AI System Registry

Organisations managing multiple AI systems will benefit from xWiki's structured data capabilities to create an internal AI system registry. Each registered system can have a page with standardised fields for system name, risk classification, deployment status, responsible person, last conformity review date, and links to the full technical documentation. Custom queries can generate registry dashboards showing all high-risk systems, their compliance status, and upcoming review deadlines, giving management and compliance teams a centralised view of the organisation's AI portfolio.

Organisations navigating the AI Act alongside other EU regulations will find our guides on eIDAS trust services documentation and PCI DSS documentation useful for understanding how xWiki supports multi-regulation compliance documentation strategies.
