Connected visual scholarship

Pictures are not endpoints. They are connections.

Yenda is an open-source environment for connected visual scholarship: annotate image regions, describe and relate them semantically, compare them across a corpus, collaborate on their interpretation, and publish the resulting research.

For digital humanities, eScience, archives, museums, and image-led research.

01 Identify a region
02 Describe its meaning
03 Connect the corpus

One vision. A new foundation.

HyperImage now lives inside Yenda—and grows beyond it.

Successor, integration, expansion.

Yenda is not a break with HyperImage. The established product vision, goal, core concepts, research model, and proven capabilities have been integrated into the new Yenda toolsuite and research platform. Yenda retains them, makes them web-native, and expands the space around them with a modern architecture and new tools.

HyperImage The proven idea
Yenda The active future
01

HyperImage is part of Yenda

Its visual annotation, semantic linking, multilingual metadata, collaborative authoring, and publication model form the proven core of the expanded Yenda platform.

02

Your projects carry forward

Yenda is fully backwards compatible with HyperImage projects, data structures, and established workflows. Existing research does not need migration-only preprocessing or a fresh start.

03

The same vision, expanded

The HyperImage 3 branch is discontinued. All ongoing development now belongs to Yenda: a modern foundation, new tools, and a wider future—without abandoning the original goal or core concepts.

Image Context Relation

Picture knowledge

Research begins where the image refuses to be just an illustration.

Mark complex subregions within images, describe them in multiple languages, and construct visual argumentation chains by linking them to other regions, images, groups, texts, websites, inscriptions, or light tables. Yenda turns a collection into a navigable corpus of evidence, relations, and interpretation.

What hypertext does for text, Yenda extends to the image—and to the relations within image corpora.

Built for visual scholarship

From close reading to connected publication.

Yenda carries HyperImage’s complete model for managing image corpora, metadata, and relationships into a modern browser workflow—and extends its modes of scholarly analysis and indexing.

Available in current beta

Annotate what matters—down to the region

Draw complex polygonal regions across multiple layers, assign colours and opacity, add rich multilingual annotations, tags, and precise link targets. AI-assisted segmentation can propose a shape while the researcher remains in control.

02

Link across the corpus

Create 1:1, 1:n, and n:n semantic relationships between regions, images, objects, texts, groups, URLs, inscriptions, and light tables—then make those annotations accessible through indices and backlinks.

03

Shape metadata around the research

Use flexible, extensible metadata templates, multiple schemas per element, multilingual project metadata, tags, and rich text instead of forcing heterogeneous research material into one rigid catalogue.

04

Organise visually

Build curated groups and light tables, arrange images with annotations, browse by tags, and search project content while preserving the visual structure of scholarly argumentation.

05

Research together

A server-based research and publication environment supports both individual scholarship and collaborative projects, with role-aware access, live notifications, project users, and protected editing.

06

Publish and keep your work portable

Compile interim results or final versions as navigable online/offline hypermedia publications, and exchange complete projects through the established PeTAL 3 format—including large, resumable export jobs.

A living platform

What works now—and what comes next.

Yenda’s capabilities are grouped by their actual maturity. The current beta already supports the central workflow of connected visual scholarship; development and research goals remain clearly identified.

Browser-native by design

No Java launcher. No legacy installation ritual.

Yenda opens where contemporary research happens: in the browser. The interface preserves the depth of HyperImage’s authoring model while adding guided onboarding, contextual help, live German/English UI switching, accessible controls, and resilient long-running workflows.

Continuity by design

For existing HyperImage projects

Backward compatibility is a first-class capability in Yenda—not a migration footnote. Existing projects, data structures, and established research workflows remain authoritative while gaining access to Yenda’s browser-native environment and current beta features.

  • Continue from existing HyperImage projects
  • Preserve established structures and workflows
  • Move into a modern browser-based research environment

Interoperability

Standards are commitments, not decoration.

Yenda is being prepared to connect with established scholarly and cultural-heritage ecosystems. These are explicit implementation and validation targets; none is presented as accepted conformance until it passes Yenda’s acceptance suite.

01 Selected beta access

Hosted Yenda

No installation required. The hosted Yenda environment is currently available to selected research projects and beta testers.

Request beta access
02 Public release planned

Self-host Yenda

Run Yenda on infrastructure controlled by your institution. The public source release will be available under an open-source license.

03 In active development

Docker

An official container-based installation is being prepared for straightforward evaluation and institutional deployment.

Open by principle

Research infrastructure should be inspectable, portable, and shared.

Like HyperImage before it, Yenda is being developed as open-source research infrastructure. Its implementation will be made publicly inspectable and reusable together with the public release.

Source publication Planned with the public release

Available to selected beta projects

The image was always more than a surface. Yenda makes its relationships visible.
