EN 301 549 Conformance Mapping

This document maps Aletheia by Lonia AI against the clauses of EN 301 549 V3.2.1, the harmonised European standard currently in force for ICT accessibility, and records preparation for V4.1.1. It is written to be read by procurement teams, accessibility authorities, and users who need a concrete, clause-level answer.

Last reviewed: July 14, 2026

Introduction

Aletheia by Lonia AI targets conformance with EN 301 549 V3.2.1, the version referenced in the Official Journal of the European Union and in force as of this review date. EN 301 549 V3.2.1 incorporates the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. Aletheia's engineering target is WCAG 2.2 Level AA, which is a superset of WCAG 2.1 Level AA, so the product is built above the floor the current standard sets.

This document also prepares for EN 301 549 V4.1.1, which was published for public review as V4.1.0 in November 2025 and is expected to be referenced in the Official Journal in October 2026. V4.1.1 is expected to incorporate WCAG 2.2 Level AA. Because Aletheia already targets WCAG 2.2 Level AA, the additional success criteria V4.1.1 introduces are already in scope for the product. Their readiness is recorded in the V4.1.1 preparation section below.

Conformance status in this document is based on self-evaluation. A formal audit by an independent third party is planned and has not yet been completed. Where the product's status against a clause cannot be defended from current evidence, the status is recorded as "Under evaluation" or "Pending third-party audit" rather than claimed.

Scope

This mapping covers the following, together referred to as Aletheia:

  • The Aletheia web application, where users process and remediate web pages and documents on their own device.
  • The Aletheia marketing website at this domain.
  • The institutional administration dashboards used by Campus and Enterprise account administrators.

Aletheia is delivered as web content and as software. The chapters of EN 301 549 that apply to it are primarily Chapter 5 (Generic Requirements), Chapter 9 (Web), Chapter 11 (Software), and Chapter 12 (Documentation and Support Services). Chapter 10 (Non-web Documents) applies to Aletheia's exported files. Chapters that describe hardware, two-way voice, video, and relay or emergency services do not apply and are marked accordingly below.

Standards referenced

  • EN 301 549 V3.2.1 (March 2021), the harmonised European standard currently referenced in the Official Journal of the European Union. It incorporates WCAG 2.1 Level AA.
  • WCAG 2.2 Level AA, the World Wide Web Consortium Recommendation of October 2023. This is Aletheia's engineering target.
  • EN 301 549 V4.1.1 (expected October 2026), the forthcoming revision expected to incorporate WCAG 2.2 Level AA. Preparation for this version is documented, not claimed as current conformance.

Conformance approach

The sections below map the applicable chapters of EN 301 549 to Aletheia's current implementation, one clause or clause group at a time. Each row states whether the clause is applicable to Aletheia and records the product's status using the vocabulary in the legend below. Where a chapter's requirements reference WCAG success criteria, Chapter 9 gives the criterion-level detail and the other chapters reference it rather than repeat it.

Status legend

  • Meets (self-assessed): the requirement is implemented and verified by Aletheia's own testing; not yet confirmed by a third-party audit.
  • Partially meets: the requirement is met for most content or cases, with a specific known limitation recorded.
  • Does not meet: the requirement is not currently satisfied.
  • Under evaluation: Aletheia's status against the requirement has not yet been determined from evidence and is not claimed.
  • Pending third-party audit: the requirement depends on formal test evidence that has not yet been produced.
  • Not applicable: the requirement addresses a technology or function Aletheia does not have.

Chapter 4: Functional Performance Statements

Chapter 4 describes the outcomes a user with a given need should be able to achieve. It is addressed through the technical requirements in the later chapters. The table records how Aletheia addresses each functional performance statement.

Chapter 4. Functional performance statements and how Aletheia addresses each.
Clause Functional performance statement Status Note
4.2.1Usage without visionMeets (self-assessed)Semantic structure, name and role exposure, and full keyboard operation target screen reader use with NVDA, JAWS, and VoiceOver.
4.2.2Usage with limited visionMeets (self-assessed)Text reflow, resize to 200 percent without loss, and contrast at or above 4.5:1 for normal text.
4.2.3Usage without perception of colourMeets (self-assessed)Colour is never the only means of conveying meaning; state is also given as text, icon, or position.
4.2.4Usage without hearingNot applicableNo audio-only information is required to operate the product. User-initiated audio export is a text-to-speech convenience, not a required channel.
4.2.5Usage with limited hearingNot applicableNo required audio content. See row 4.2.4.
4.2.6Usage without vocal capabilityMeets (self-assessed)No operation requires speech input.
4.2.7Usage with limited manipulation or strengthMeets (self-assessed)Full keyboard operation, no required dragging, and touch targets of at least 44 by 44 pixels.
4.2.8Usage with limited reachMeets (self-assessed)Runs on the user's own device; layout reflows to a 375 pixel viewport so controls stay within reach on small screens.
4.2.9Minimise photosensitive seizure triggersMeets (self-assessed)No content flashes more than three times per second.
4.2.10Usage with limited cognition, language, or learningMeets (self-assessed)Plain-language copy, consistent navigation and help placement, clear error messages, and OAuth sign-in that removes password memory burden.
4.2.11PrivacyMeets (self-assessed)Accessibility features carry the same privacy protections as the rest of the product; on-device processing keeps document content local.

Chapter 5: Generic Requirements

Chapter 5 covers requirements that apply across ICT regardless of its form. Most of Chapter 5 addresses physical hardware and closed systems, which do not apply to Aletheia. The clauses that do apply are recorded below.

Chapter 5. Generic requirements, applicability, and Aletheia's status.
Clause Requirement Applicable Status and note
5.1Closed functionalityNot applicableAletheia runs on the user's own general-purpose device with the user's own assistive technology. It does not restrict the attachment or use of assistive technology, so it is not closed functionality.
5.2Activation of accessibility featuresApplicableMeets (self-assessed). Aletheia does not obstruct platform accessibility features and honours operating system settings such as reduced motion.
5.3BiometricsNot applicableAletheia does not use a biological characteristic as the only means of user identification or control. Authentication is OAuth single sign-on.
5.4Preservation of accessibility information during conversionApplicablePartially meets. When Aletheia produces remediated output it carries structure and alternative text through. For tagged PDF export, non-Latin scripts are a known limitation recorded in Chapter 10; plain text export preserves all Unicode content without loss.
5.5Operable parts (5.5.1 means of operation, 5.5.2 tactile discernment)Not applicableAddresses physical operable parts on hardware. On-screen controls are covered in Chapter 9 and Chapter 11.
5.6Locking or toggle controls (5.6.1 tactile or auditory status, 5.6.2 visual status)Not applicableAddresses hardware locking keys. On-screen toggle state is covered under name, role, and value in Chapter 9 and Chapter 11.
5.7Key repeatNot applicableAletheia provides no physical keyboard. Key repeat is controlled by the user's own platform.
5.8Double-strike key acceptanceNot applicableAletheia provides no physical keyboard. See row 5.7.
5.9Simultaneous user actionsApplicableMeets (self-assessed). No function requires simultaneous user actions such as multiple keys or points of contact at once; every function is available through single-point activation.

Chapter 6: ICT with Two-Way Voice Communication

Not applicable. Aletheia is not a real-time text, voice, or video communication service. Chapter 6 does not apply.

Chapter 7: ICT with Video Capabilities

Not applicable. Aletheia does not deliver video content with synchronised audio in the sense of the standard. The optional audio export is text-to-speech playback of remediated text, not video, so Chapter 7 does not apply.

Chapter 8: Hardware

Not applicable. Aletheia is software delivered as web content and a client application. It ships no hardware, so Chapter 8 does not apply.

Chapter 9: Web

Chapter 9 is the primary chapter for Aletheia. Under EN 301 549 V3.2.1, Chapter 9 requires web content to satisfy the WCAG 2.1 Level A and Level AA success criteria. Aletheia targets WCAG 2.2 Level AA, so the tables below map every WCAG 2.2 Level A and Level AA success criterion, grouped by the four WCAG principles. Criteria new in WCAG 2.2 are noted; they are not required by V3.2.1 but are in scope for V4.1.1 and for Aletheia's own target.

The status in these tables reflects self-evaluation of the marketing website and the web application. A formal third-party audit has not yet been completed. The product's overall conformance is partially conformant, driven by the exported-document limitations recorded in Chapter 10 and the documentation limitation recorded in Chapter 12. Five criteria (1.3.1, 1.3.2, 1.4.10, 2.4.1, and 2.4.11) are held at Partially meets pending scheduled manual verification (Workstream B29), matching the status held in the VPAT accessibility report and the EU Accessibility Statement; the remaining criteria are self-assessed as met below.

4.1.3Status MessagesAAMeets (self-assessed)Status messages are announced without moving focus.

Chapter 10: Non-web Documents

Chapter 10 applies the WCAG success criteria to documents that Aletheia produces, chiefly its exported files. This is where Aletheia has known limitations, and they are documented honestly here rather than smoothed over.

Chapter 10. Exported document formats and their accessibility status.
Export format Expectation Status Note
Tagged PDFStructure tags, alternative text, reading order, and outlines consistent with PDF/UA and the WCAG-based clauses of Chapter 10.Partially meetsExported PDF carries structure tags, alternative text, and outlines for Latin-script content. Non-Latin scripts may show fallback characters in the current build.
Tagged PDF (screen reader evidence)Verified behaviour with NVDA, JAWS, and VoiceOver reading the exported file.Pending third-party auditFormal screen reader test evidence against exported PDF output has not yet been produced.
Plain textFull preservation of content without loss.Meets (self-assessed)Plain text export preserves all Unicode content, including non-Latin scripts, without loss. It is the recommended format where scripts must be retained exactly.

Chapter 11: Software

Chapter 11 applies to Aletheia's client-side application behaviour and, because Aletheia produces accessibility-remediated content, to its role as an authoring tool. Where a clause simply restates a WCAG success criterion for software, the status matches the corresponding row in Chapter 9.

Chapter 11. Software requirements and Aletheia's status.
Clause Requirement Applicable Status and note
11.1 to 11.4Perceivable, operable, understandable, and robust softwareApplicableMeets (self-assessed). The application is built to WCAG 2.2 Level AA; see Chapter 9 for criterion-level detail.
11.5Interoperability with assistive technologyApplicableMeets (self-assessed). The application exposes name, role, state, and value through platform accessibility services and does not disrupt assistive technology.
11.6Documented accessibility usageApplicableMeets (self-assessed). Accessibility features are documented in the accessibility statement and this mapping.
11.7User preferencesApplicableMeets (self-assessed). The application honours platform settings such as reduced motion and text size.

12.2.3Effective communicationMeets (self-assessed)Support is offered by accessible email and accessible web forms.
12.2.4Accessible documentation from supportMeets (self-assessed)Written support responses are provided in accessible plain text and HTML email.

Chapter 13: ICT Providing Relay or Emergency Services

Not applicable. Aletheia does not provide relay services or access to emergency services, so Chapter 13 does not apply.

Preparation for EN 301 549 V4.1.1

EN 301 549 V4.1.1 is expected to incorporate WCAG 2.2 Level AA, adding the success criteria new to WCAG 2.2 to the mandatory set. Because Aletheia already targets WCAG 2.2 Level AA, these criteria are already in scope. The table records readiness. Criteria at Level AAA sit outside Aletheia's Level AA target and are noted as such rather than claimed as a conformance obligation.

Testing methodology

This mapping is based on the following evaluation methods:

  • Automated accessibility testing with axe-core, run continuously as part of development.
  • Manual keyboard-only testing by the Aletheia team.
  • Manual checks of semantic structure, focus order, contrast, and form labelling.
  • A target of support for the NVDA, JAWS, and VoiceOver screen readers.

A formal audit by an independent third party is planned and has not yet been completed. Screen reader test evidence against exported PDF output is pending. This document will be updated when that evidence and that audit are available.
