This document provides an overview of the Dutch Digital Heritage Network (NDE) programme. It discusses building a digital heritage network by rethinking the current digital network to focus on users and be more interconnected. The current work involves improving data usability at the source, a shared terminology service, registering organizations and datasets, and rethinking the aggregation landscape. Lessons learned include the time needed to implement new technologies and the importance of examples. Next steps involve maturing the design based on current infrastructure and decentralizing implementations.

Goal: A network service for shared terminology for Dutch digital heritage
● “use things, not strings” [1]
● select relevant terminology sources for the context:
○ search in general available definities (Wikidata, geonames, Getty thesauri)
○ search in shared definitions in the (Dutch) heritage domain
● use real time (federated) queries
● harmonize results in a generic API (skos based)
● pick your favorite URI and store it

- 9. National Digital Heritage strategic plan (2015) The Digital Heritage Network (NDE) aims at increasing the social value of the heritage information maintained by libraries, archives, museums and other cultural heritage institutions. This strategy offers a perspective on developing a national, cross-sector infrastructure of digital heritage facilities. It focuses on long term cooperation between the government and the institutions on national, regional and local level. It is about organizing the network of people and information!

- 10. Bridging networks Seeking cooperation between: ● about 1500 organizations ● libraries, archives, museums, other institutions ● national, regional, local networks ● using different IT environments ● many different goals and funding schemes Aligning digital activities ● improving digital visibility ● publication and reuse of digital information ● exchanging knowledge and information

- 14. Manifesto
- 15. Building the digital heritage network Rethinking the current digital network
- 16. Focus on users Users want to be able to find and use all sources available from archives, libraries, museums, and other collections, preferably in as few searches as possible and at the lowest possible cost. Right now, users cannot easily locate a coherent overview of relevant sources. Thinking from the user’s perspective also means seeking out the digital platforms and work environments where potential users can already be found. Having a social media presence or being findable through search engines can be more effective methods of reaching the public than simply maintaining a website. From: National Digital Heritage Strategy
- 17. Users start at Google… but many (long tail) information doesn’t show up...
- 18. So we have nice portals! but: ● which one to choose? ● can I browse from one portal to another?
- 19. And behind the scenes... Aggregator Aggregator Aggregator Aggregator Service portal Aggregator Service portal Aggregator Service portal data source providers Service portal data source provider
- 20. Rethink the network: • maximize the usability of data at the source • refer to data instead of copying • build service portals as views based on a common, interconnected data layer • minimize the intermediate layers In general: • open and sustainable network based on Linked Data (and FAIR) principles • build on ‘web-centric’ technologies (HTTP, RDF, Web API’s) • apply decentralized/distributed technologies where possible Inspired by the work of Ruben Verborgh, Herbert Van de Sompel and colleagues: See for example: Miel Vander Sande et al. , Towards sustainable publishing and querying of distributed Linked Data archives - (JoD 2017) Design principles for the discovery infrastructure
- 21. “You can only be free if you follow rules…”1 At the data source level: • use sustainable URIs to identify the organizations, collections and resources • use formal definitions for persons, places, concepts, events • add support for cross-domain discovery (Schema.org, Europeana Data Model) • use domain data models for collaboration • publish the information about the organization, collections and resources as Linked Data => IT vendors are strategic partners for the implementation! Implementing Linked Data principles (1) 1: http://slides.verborgh.org/ELAG-2018/#
- 22. At the network level: • provide access to a ‘network of terms’ for shared terminology • provide overview organizations and datasets (registry) • implement standards for provenance and rights • support infrastructure for navigating through the linked network • support tools for alignment and linking • promote reuse of tools and data • optimize the usability of current infrastructure Implementing Linked Data principles (2)
- 23. Our current work... Building the distributed network of digital heritage information
- 24. Roadmap for NDE’s distributed network 1. improve the usability of the data source: 2. facilitate a service for shared terminology for Dutch digital heritage 3. create a transparent, machine readable view of the network 4. improve the current aggregation infrastructure 5. investigate new discovery technologies:
- 25. Linked Data at the source ● Collection management systems publishing linked data ● Strategy: work with IT suppliers to implement Linked Data technology ● Working with the “big 5” IT suppliers (>90% of the market) ● Step by step implementation strategy: ○ short term hacks - “wrappers”, stylesheets, other intermediate solutions ○ start with real use cases together with institations ○ roadmap to full support for the NDE functionality
- 26. Linked Data at the source...
- 29.

- 31. Register organizations and datasets ● Create an overview of the NDE network ● Create an overview of the available data in the network ● Promote the use of unique, stable and machine readable definitions of organizations and datasets ● Define a common data model for the different domains ● Align with community standards like DCAT and VOID ● Design a distributed model to integrate the data in the various platforms

- 36. Lessons learned & next steps
- 37. Lessons learned so far ● New technologies take a long time to implement ● Strategic choices for improving the legacy systems (evolution) or building the new ones (disruption) ● Showcases and example implementations are import to broaden the uptake ● Moving in the right direction is more important than doing everything right ● In the end its about connecting people and organizations
- 38. Next steps ● Mature design and functionality based on the current infrastructure ● Work on more implementations in local contexts ● Implement solutions in a decentralized and sustainable way, close to the core processes ● Intensify the cooperation with IT suppliers and other stakeholders in the network ● Implement a design, build, deploy and maintain cycle for network services ● Support research on decentralized linked data discovery and publication
