However, the (meta)data generated through the HGF's research and operations is typically siloed within institutional infrastructure and often within individual teams. The result is that the wealth of the HGF's (meta)data is stored and maintained in a scattered manner, and cannot be used to its full value to scientists, managers, stratgists, and policy makers.
However, the (meta)data generated through the HGF's research and operations is typically siloed within institutional infrastructure and often within individual teams. The result is that the wealth of the HGF's (meta)data is stored and maintained in a scattered manner, and cannot be used to its full value to scientists, managers, strategists, and policy makers.
To address this challenge, the Helmholtz Metadata Collaboration (HMC) is launching the **unified Helmholtz Information and Data Exchange (unHIDE)**. This initiative seeks to create a lightweight and sustainable interoperability layer to interlink data infrastructures and provide greater, cross-organisational access to the HGF's (meta)data and information assets. Using proven and globally adopted knowledge graph technology (Box 1), unHIDE will develop a comprehensive association-wide Knowledge Graph (KG) the "Helmholtz-KG": a solution to connect (meta)data, information, and knowledge.

To ensure ease of use, the Helmholtz-KG will be based on a lightweight and internationally adopted interoperabiliy architecture based on schema.org semantics and JSON-LD serialisation [2]. This architecture widely used by data producers - including public, private, and governmental data systems - to link and expose scattered, diverse digital assets. By reusing this architecture, unHIDE will ensure that the Helmholtz-KG is able to natively interoperate with global systems.

While the foundation of the Helmholtz-KG will reuse standard web architectural elements and proven, globally adopted conventions, the KG itself is modular by nature: Graphs can be merged, split, independently managed, and readily interfaced with other digital resources without compromising core integrity and functionality. In this manner, Helmholtz data scientists and engineers will be able to propose and test extensions to the graph with minimal overhead, which wll support the ability to extend into existing and well-established systems in the HGF.

This modularity (especially the ability to securely and independently manage parts of the overall graph) will also allow to realize different modes of access to digital assets (e.g. respecting sensitivity and confidentiality but also permitting full openness). The initial implementation of the Helmholtz-KG will not contend with sensitive or confidential data, but such capacities (e.g. user management, license recognition across (meta)data holdings, and authentication) can be explored and implemented when the core technology and operational procedures are stabilised.

The implementation the Helmholtz-KG architecture is inspired by the federation of stakeholders in IOC-UNESCO's Ocean Data and Information System (ODIS), interconnected by the [ODIS Architecture](https://book.oceaninfohub.org/) [2], and rendered into a knowledge graph federating over 50 partners across the globe by the Ocean InfoHub Project (OIH). Personnel from the HMC's Earth and Environment Hub chair the ODIS federation and lead the technical implementation of OIH, offering direct alignment with unHIDE.

Following the initial implementation the semantic expresivness of the graph can be increased by integrating domain ontologies such as the HMC developed [Helmholtz Digitization Ontology](https://codebase.helmholtz.cloud/hmc/hmc-public/hob/hdo) (HDO), which provides precise and comprehensive semantics of the concepts and practices used to manage digital assets.

The Helmholtz-KG will offer multiple options for existing and emerging HGF infrastructures, data providers, and communities to declare their resources and digital assets in the graph for discoverability. We will prioritise the recommended publishing process for structured data on the web (as used by ODIS/OIH and many others): data providers would either 1) provide a sitemap or robots.txt file which will direct harvesting software to a collection of JSON-LD/schema.org documents or 2) expose JSON-LD snippets in the document head element of a web resource (i.e. HTML document). Both approaches are described in the publisher documentation of the Ocean InfoHub Project [3].
