The FAIRCORE4EOSC project started in June 2022 and will deliver nine new EOSC-Core components in support of a FAIR research life cycle, bridging the gaps identified in the EOSC SRIA. More specifically, the components will enable an EOSC PID infrastructure, an EOSC research software infrastructure, support for sharing and access to metadata schemas and crosswalks and offer advanced research-intent driven discovery services over all EOSC repositories. This deliverable summarises the overall technical specifications for the FAIRCORE4EOSC components. The deliverable is a snapshot of the input received from WP2, WP3, WP4, WP5, WP6 and WP7 via the milestones at M7. This deliverable will be further updated during the project duration on the project wiki to take into account new requirements and feedback received. The Wiki page that this deliverable is derived from automatically mirrors updates to the content provided by the work packages.
