Adobe Acrobat(also: Acrobat Pro, Adobe Acrobat Pro, Acrobat DC)

Adobe's commercial software suite for creating, editing, and managing PDF documents, including accessibility remediation features. Acrobat Pro includes tools for adding tags to PDF documents, setting reading order, editing document structure through a tag tree, running…

Artifact(also: PDF artifact, Background artifact)

In PDF accessibility, an artifact is content that is marked as decorative or non-essential and should be ignored by assistive technologies. Examples include page numbers, headers/footers, decorative images, background graphics, and watermarks. Properly marking artifacts prevents…

Borne-Accessible Document(also: born-accessible, natively accessible document)

A document that is created accessibly from the outset—its semantic structure, headings, alt text, and tags are built in at authoring time rather than added later through remediation. Borne-accessible PDFs come out of authoring tools (e.g., Microsoft Word, LaTeX with…

Content tagging(also: Structural tagging, Semantic tagging)

The process of adding structural markup to document content that identifies the role and meaning of each element. In PDF accessibility, content tagging involves marking regions of a document as paragraphs, headings, lists, tables, figures, or artifacts so that assistive…

Document Layout Analysis(also: DLA, page layout analysis)

A computer-vision task that identifies and classifies the visual regions of a document page—headings, paragraphs, tables, figures, captions, lists, headers, and footers—typically using object-detection models trained on datasets such as DocLayNet, PubLayNet, or DocBank. Document…

Document structure(also: Structural hierarchy, Document hierarchy)

The logical organization of a document into meaningful components such as headings, sections, paragraphs, lists, and tables. Proper document structure enables assistive technology users to navigate efficiently, understand relationships between content sections, and access…

PDF Form(also: PDF Fillable Form, Interactive PDF Form, AcroForm)

A PDF document that contains interactive form fields — text boxes, checkboxes, radio buttons, signatures, dropdowns — that users can fill in and submit electronically, rather than a static PDF meant only for reading. PDF forms are widely used for government applications,…

PDF Tagging(also: Tagged PDF, PDF Tags)

The process of adding a logical structure tree to a PDF so that assistive technologies can interpret the document's content, reading order, and semantics independently of its visual layout. Tags label each piece of content with its role — heading, paragraph, list item, figure,…

Table accessibility(also: Accessible tables, Data table accessibility)

The practice of structuring data tables so they can be understood by assistive technology users. Accessible tables require proper markup that distinguishes header cells from data cells, establishes relationships between headers and the data they describe, provides captions or…

Tooltip(also: Form Field Tooltip, Accessible Name (PDF))

In PDF forms, a tooltip is the programmatic label associated with a form field that assistive technologies read aloud when the user reaches that field. Unlike HTML, PDF does not have a native label-to-field association, so the tooltip carries the accessible name. Best practice…
