Each one links to its EU funding record and the partners it works with: a starting list for building a consortium.
Projects should contribute to all of the following expected outcomes:
This topic aims at implementing real use cases and carrying out demanding end-to-end testing of the platform and its tools, in order to verify its capabilities and improve the ECCCH.
The activities carried out should focus on concrete use cases, undertaken by the participating institutions, professionals and researchers with a view to improve their results or work processes.
The activities carried out should make use of several of the key features of the ECCCH, including the user tools implemented on it[1]. Such key features may include use of the advanced digital twins, of the large-scale cooperation and co-creation features, of the digital continuum or of the advanced features for commercial cooperation with, for example, cultural and creative industries[2]. Activities carried out may also focus on the seamless interconnection of the ECCCH with other related platforms such as the Common European Data Space for Cultural Heritage and the European Open Science Cloud. Proposals should outline a focus of the planned activities that best achieve the expected outcomes, which may include some of the aspects mentioned.
Activities should involve a wide range of different organisations from across Europe, in accordance with the focus chosen. Entities from at least five different Member States or Associated Countries should be involved as active users of the ECCCH platform. Also, entities of different characteristics should be involved, such as small and large organisations, from different subsectors/areas of activity or scientific disciplines, etc.
The activities carried out and the results generated should be properly documented so as to serve as a good base for improvements or corrections of the platform and/or of the user tools implemented on it, and also for communicating innovative uses of the ECCCH. Contributions should be made to extend the user base of the ECCCH by promoting use cases and outreach activities, possibly together with or coordinated with other ECCCH projects.
Projects funded under this topic may build on testing or other activities carried out by other ECCCH projects, but must not duplicate activities that are funded under other ECCCH projects. Activities should add new value to the ECCCH. Therefore, projects funded under this topic should coordinate closely with previously funded ECCCH projects and provide for sufficient flexibility so as to avoid duplication and ensure that the activities carried out offer important contributions to validate and improve the platform.
Proposals should foresee own capacity to implement important improvements and fix problems detected. Such modifications or extensions of the ECCCH platform functionality should be carried out in accordance with the data model and the software development and documentation guidelines of the ECCCH, established by the project funded under topic HORIZON-CL2-2023-HERITAGE-ECCCH-01-01[3]. All software and other related deliverables should be compliant with the guidelines elaborated by the project funded under topic HORIZON-CL2-2023-HERITAGE-ECCCH-01-01, and should be implemented in compliance with the design of the ECCCH, using the low-level libraries established by the project funded under topic HORIZON-CL2-2023-HERITAGE-ECCCH-01-01.
All software developed should be open source, licensed under a CC0 public domain dedication or under an open-source licence as recommended by the Free Software Foundation[4] and the Open-Source Initiative[5]. If the use of open source software components would require disproportional efforts or significantly diminish the quality or performance of the software, proprietary components may be used provided that: An open functional replacement is available; they do not introduce proprietary data formats or Application Programming Interfaces; a full user license free of charge for an unlimited period of time is granted to the consortium responsible for the ECCCH and all its users. Applicants should state clearly if all developed software will be open source, and if not clearly explain the reasons.
To the extent that data is produced, efforts should be made to ensure that it is FAIR (Findable, Accessible, Interoperable and Re-usable). To the extent that new or modified interoperability standards need to be developed for data sharing within and across data ecosystems, these should build on the FAIR data principles and leverage already adopted practices, especially those in the relevant European common data spaces and in the European Research Infrastructures.
Financial support to third parties may be used to facilitate the engagement with ECCCH users beyond the project consortium. The financial support to third parties can only be provided in the form of grants.
In order to ensure good coordination among the different ECCCH projects, proposals should make provisions to actively participate in the common activities of the ECCCH initiative. Projects funded under this topic should coordinate technical work with the relevant projects funded under other call topics of the ECCCH initiative, and contribute to the activities and objectives of the project funded under the topic HORIZON-CL2-2023-HERITAGE-ECCCH-01-01. Proposals should include a budget for the attendance to regular joint coordination meetings, and may consider covering the costs of any other joint activities without the prerequisite to detail concrete joint activities at proposal stage.
Projects funded under this topic should set up their project websites under the common ECCCH website, managed by the project funded under topic HORIZON-CL2-2023-HERITAGE-ECCCH-01-01.
The Commission expects the different projects funded under this topic to establish regular coordination mechanisms in order to ensure synchronised planning, as well as synergy and/or complementarity of deliverables and outcomes, where this is appropriate.
The Commission estimates that a project duration of approximately 2 – 2.5 years is appropriate for the projects funded under this topic.
Please also refer to the Destination introduction text to consider some key characteristics of the vision for the ECCCH.

Applicants asked the EU 4 questions about this call and the EU published the answers. They clarify the call documents but do not replace them.
This topic has specific conditions, as described in the Topic conditions and documents section:
“Beneficiaries may provide financial support to third parties to cultural heritage institutions, in take-up of tools, technologies and for populating and validating the relevant use cases through experiments. A maximum of 15% of the budget may be dedicated to financial support to third parties. The maximum amount to be granted to each third party is EUR 60 000.”
Applicants using FSTP must complete and submit with the proposal the additional annex of Information on financial support to third parties (HE)Word (as available in the Submission system), and make sure that the information is consistent with the other parts of the proposal, e.g. Detailed budget table, the work package descriptions, etc.
Third parties receiving financial support cannot implement action task but participate in the action as recipients.
The guidance titled Good practices for implementing financial support to third parties (FSTP) in EU grantsPDF provides further details related to proposal submission and evaluation. In particular:
Regarding Budget structure and cost estimations, the FSTP is a specific cost category in the normal budget (Lump sum grants: Detailed budget table, cost category D.1 Financial support to third parties) and is usually based on actual costs; this means that the FSTP budget is normally based on cost estimations which you will need to present as part of your proposal.
Note that cost category D.1 should be used ONLY for the amount of the financial support itself. All other amounts incurred for the FSTP (e.g. costs relating to the preparation or management of the FSTP, in-kind contributions to the recipients) must be charged under other cost categories (e.g. A. Personnel costs, B. Subcontracting or C.3 Other goods, works and services).
Also for lump sum grants, your budget estimates must be:
o − in line with the cost eligibility rules (see AGA — Annotated Grant Agreement, art. 6*)
o − in line with your normal practices
o− reasonable/not excessive
o− in line with and necessary for the activities proposed.
Regarding operational and financial capacity, please note that managing FSTP at large scale is usually linked to a significantly higher burden for you, both in terms of operational and financial capacity; in order to minimise the risk both for you and us, please make sure that you (and other partners that propose to manage FSTP) have sufficient operational and financial capacity to successfully implement the planned activities. If financial or operational capacity is weak, the EU services may ask such activities to be removed from the project (or to move the activities to another participant).
The rules and conditions to use FSTP are described in the HE Model Grant AgreementPDF (Articles 6.2.D.1 and Article 9.4) and state that the consortium must ensure an objective and transparent selection procedure of third-party recipients. At project implementation stage, cascade funding calls must be published on the Funding & Tenders Portal. To publish calls for cascade funding, the project has to prepare the information via the Funding &Tenders Portal (My Projects section). Then the Project Officer validates and publishes the information on the Portal. (See steps to proceed in the IT HOW TO: Cascade Funding Calls / Financial Support for Third Parties (FSTP) - IT How To - Funding Tenders Opportunities).

For beneficiaries receiving an operating grant, indirect costs are not eligible. However, the shares calculated by the Excel table contain indirect costs, and there is no function to remove indirect costs for individual beneficiaries in the Excel table. In this situation, the applicant with an operating grant should adjust the amount entered in the Part A budget table by subtracting the indirect costs. Applicants are expected to explain this in the comments tab of the Excel detailed budget table. If the proposal is selected for funding, the lump sum shares calculated by the Excel detailed budget table must be adjusted during grant preparation to the Part A requested amount (i.e. subtract the amounts corresponding to indirect costs).

Financial Support to Third Parties (FSTP), also called cascade funding, allows project beneficiaries to award grants to third-party recipients i.e. entities or persons that are not partners in the consortium. The rules and conditions to use FSTP are described in the HE Model Grant AgreementPDF (Articles 6.2.D.1 and Article 9.4) and state that the consortium must ensure an objective and transparent selection procedure of third-party recipients.
Third parties receiving financial support cannot implement action task but participate in the action as recipients.
The guidance titled Good practices for implementing financial support to third parties (FSTP) in EU grantsPDF provides further details related to proposal submission and evaluation.
