This paper examines the strategic transition of the OPERAS research infrastructure into a European Research Infrastructure Consortium (ERIC), proposing a functional co-hosting model between Poland and France to foster a scholarly ecosystem. By establishing the Central Hub and a technical Innovation Lab in Poland alongside a Community Hub in France, this framework enables functional specialisation while mainstreaming Central and Eastern European perspectives within the global Open Science movement.

The integration of high-performance computing and AI resources from the Poznań Supercomputing and Networking Center (PCSS) facilitates the processing of complex, multilingual SSH datasets, ensuring that digital innovation remains community-governed. Through services such as the GoTriple discovery platform, the PRISM transparency tool, and the promotion of "Diamond" Open Access models, the infrastructure empowers researchers by removing financial and linguistic barriers.

Furthermore, the OPERAS Innovation Lab pioneers new modes of scholarly writing and digital editions, providing a robust foundation for traditional philological inquiry. Ultimately, hosting the OPERAS ERIC in Poland signifies the maturity of the national research system and its commitment to a resilient, inclusive habitat for scholarly communication that preserves bibliodiversity and cultural heritage across national boundaries.
