Digital Heritage: Complete Definition and Guide

What is digital heritage?

Digital heritage refers to the full range of processes and technologies that enable cultural, historical and memorial resources to be preserved, enriched and disseminated in digital form. It is not simply about digitising documents or objects: it is a comprehensive approach that transforms how cultural institutions, museums, foundations and public bodies share their legacy with the world.

Digital heritage encompasses the creation of dedicated web platforms, cartographic databases, virtual tours, multilingual content management systems and interactive applications that make heritage accessible to a global audience. This approach goes beyond mere conservation: it creates new experiences of discovery, research and learning that did not exist in the physical world.

In a context where collective memory is threatened by time and oblivion, digital tools offer unprecedented preservation and dissemination capabilities. European cultural routes, museum collections, historical archives and oral testimonies find in digital technology a powerful and enduring vector of transmission.

Why it matters

Heritage preservation through digital means addresses fundamental challenges that extend far beyond the technological realm. Cultural institutions that invest in digital platforms experience a profound transformation in their ability to fulfil their mission of transmission.

• Universal accessibility: digitised heritage made available online is accessible to anyone with an internet connection, regardless of geographical location. A student in Tokyo can explore a European memorial route as easily as a visitor on site.
• Long-term preservation: physical media deteriorate over time. Digital databases, properly backed up and maintained, offer theoretically unlimited preservation of heritage content.
• Continuous enrichment: unlike a fixed physical exhibition, a digital platform can be continuously enriched with new content, testimonies, documents and points of interest.
• Multilingualism: modern heritage platforms built on multilingual CMS allow heritage to be made accessible in many languages, considerably widening the audience.
• Tourism value: digital heritage directly supports cultural tourism by enabling visitors to prepare their trip, discover lesser-known sites and extend their experience after travel.
• Research and education: researchers, teachers and students benefit from structured, indexed access to heritage resources, facilitating knowledge production and educational transmission.

How it works

Setting up a digital heritage project follows a methodical process that combines cultural expertise, technological skills and editorial vision. Every project is unique, but the main steps remain similar.

The first phase is data inventory and structuring. This involves cataloguing all available heritage resources (documents, photographs, testimonies, geographical coordinates, metadata) and organising them into a coherent data model. This step is crucial because the quality of the structuring determines all subsequent exploitation.

The second phase focuses on platform design. Information architecture is defined according to target audiences and preferred browsing modes: map navigation, thematic search, chronological journey, geographical exploration. The choice of CMS is decisive: it must offer the flexibility needed to manage multilingual content, geospatial data and rich media.

The third phase is technical development. The platform is built with a CMS capable of handling the complexity of heritage content: translations, geolocations, entity relationships, high-resolution media. Cartographic technologies (PostGIS, Leaflet, server-side clustering) allow thousands of points of interest to be visualised without degrading performance.

Finally, the launch and editorial animation phase ensures the platform lives and evolves over time. Editorial workflows allow contributors to add and update content without technical skills.

Concrete example

One of the most accomplished examples of digital heritage in Europe is the Liberation Route Europe project, a digital ecosystem built by KERN-IT for the cultural route certified by the Council of Europe. This platform traces the liberation of Europe during the Second World War through thousands of points of interest spread across several countries.

KERN-IT designed and developed the entire cartographic ecosystem: a multilingual CMS based on Wagtail managing content in more than ten languages, an interactive map displaying thousands of POIs (Points of Interest) with server-side clustering powered by PostGIS and KERN MAP, and thematic trails guiding visitors through memorial sites.

In the same vein, the Europe Remembers project, also built by KERN-IT, provides a memorial cartography platform dedicated to commemorations and events linked to European memory. These two projects illustrate how sharp technical expertise (Python, Django, Wagtail, PostGIS) put at the service of a strong cultural vision can create heritage transmission tools on a continental scale.

Implementation steps

1. Audit existing heritage: catalogue all available resources (archives, photographs, testimonies, geographical data) and assess their state of digitisation.
2. Define the data model: structure heritage information into a coherent schema that accounts for entity relationships, metadata and multilingual translations.
3. Choose the technical architecture: select a CMS capable of handling multilingualism, geospatial content and rich media. Wagtail CMS, combined with PostgreSQL and PostGIS, provides a solid foundation for this type of project.
4. Design the user experience: define browsing modes (cartographic, thematic, chronological) and discovery paths according to target audiences.
5. Develop the platform: implement the CMS, interactive cartography, search filters and consultation interfaces. Integrate server-side clustering for large volumes of geospatial data.
6. Train contributors: set up clear editorial workflows and train teams to use the CMS, ensuring autonomy in content management.
7. Animate and enrich: plan regular addition of new content, organise complementary digitisation campaigns and measure audience metrics to optimise the experience.

Related technologies and tools

• Wagtail CMS: Django-based CMS offering advanced editorial management, native multilingual support and flexible StreamField blocks for structuring heritage content.
• PostGIS: geospatial extension of PostgreSQL enabling storage, indexing and querying of geographical data. Essential for cartographic heritage platforms.
• KERN MAP: a solution developed by KERN-IT for managing large volumes of geospatial data with server-side clustering, guaranteeing optimal performance even with thousands of points of interest.
• Python / Django: the technical foundation for building robust, scalable and maintainable platforms for large-scale heritage projects.
• Leaflet / Mapbox: JavaScript interactive mapping libraries used for client-side map rendering and user interaction.

Conclusion

Digital heritage is far more than simple document digitisation: it is a strategic approach that transforms how societies preserve and transmit their cultural legacy. Digital platforms offer accessibility, richness of interaction and longevity that physical media alone cannot guarantee. KERN-IT, through its work on Liberation Route Europe and Europe Remembers, demonstrates that sharp technical expertise combined with a deep understanding of cultural challenges can create digital heritage ecosystems worthy of the legacy they serve.
