IIIF Text Image Linking Survey

Jump to bottom Edit New page
Ben W. Brumfield edited this page Apr 30, 2022 · 10 revisions

A survey of providers exposing text in their IIIF manifests conducted April 29, 2022 based on manifests included in Johannes Baiter's (@jbaiter)'s Mirador Text Overlay code

Background

The IIIF Presentation API lists several ways to refer users to textual content, including rendering elements, seeAlso blocks, and annotation on canvases. But how are content providers actually implementing these properties to expose human-transcribed text, ALTO OCR, or other formats?

This survey was conducted during the process of building a text importing function into FromThePage's IIIF client features in order to allow for OCR correction projects to be run using a IIIF-based work-flow. Some commentary and suggestions will reflect that perspective.

Survey Results

Formats exposed

Text may be exposed in several formats. Which ones do these providers support?

Provider ALTO XML HOCR Plaintext HTML
Europeana ✔️
Wellcome ✔️ ✔️
BSB ✔️
SCTA ✔️
FromThePage ✔️ ✔️

Location of Reference on Canvas

Canvases may point to text either as annotations or as external resources via seeAlso elements.

Provider otherContent seeAlso
Europeana ✔️
Wellcome ✔️ ✔️
BSB ✔️
SCTA
FromThePage ✔️ ✔️

Granularity of Text

Text may be exposed as a page at a time, an individual glyph on a portion of a canvas, or any level in between. The Text Granularity Extension defines six levels of granularity.

Provider page block paragraph line word glyph
Europeana ✔️ ✔️ ✔️ ✔️
Wellcome ✅ ✅ ✅ ✔️
BSB ✅ ✅ ✅ ✔️ ✔️
SCTA ✔️
FromThePage ✔️

(Note that XML formats like ALTO may support multiple levels of granularity at the same time through nested elements. Higher levels may be derived from the lower levels; indicated by a white check mark.)

Contextual Elements

Clients rely on contextual elements to determine what kind of content resource they're are looking at. Is it plaintext or HTML? Does it represent text at the line level or page level? Is the referenced XML file ALTO or hOCR? If these elements are added to references (like seeAlso stanzas), these contextual elements can help a client decide whether or not to fetch a resource.

Recommendations

When exposing textual content, these practices would be helpful to clients:

  1. Include format, label, and profile in any seeAlso blocks to help clients decide whether to fetch the referenced resource
  2. Include format on each annotation or annotation body to help clients understand whether treat the contents as plaintext, HTML, or something else.
  3. Include a textGranularity element on annotations, especially when multiple granularities are available.

Analysis

All canvases contain an otherContent element; some links return 404 codes (presumably for canvases containing no text).

Analysis

The AnnotationList for a canvas contains a resources element with references to text at all levels of text granularity. This is indicated by a dcType element with values of Word, Line, Block, and Page. All text contents are external.

Analysis

All resource URIs referenced in the AnnotationList return identical contents, regardless of dcType value specified in the annotation. In order to identify the word-level or line-level portion of text referenced in each annotation, clients must parse the URI fragment of the textual resource, much as they would need to parse the fragment of a canvas garget to identify the rectangle of a canvas on which to display the text.

Wellcome Library

Sample manifest: https://iiif.wellcomecollection.org/presentation/v2/b19956435 Presentation standard: 2

References within manifest

Manifests link to text by using seeAlso elements in canvases pointing to METS ALTO XML URIs, and also otherContent elements pointing to annotations.

All canvases contain an otherContent element; pages with no OCR text return valid (but empty) documents.

Each annotation appears to be at the line level of granularity, as specified in the URI. Changing URL parameters does not return annotations at a different text granularity.

Characters are embedded within the AnnotationList, rather than referenced.
