foundingGIDE Deliverable D7.1 Establish minimal shared interoperability metadata

Work Package 7 of foundingGIDE was designed to establish a core, shared set of metadata sufficient to enable cross-resource discovery and search across the participating bioimaging data resources (BioImage Archive (BIA), Image Data Resource (IDR) and SSBD) without requiring those resources to adopt a single shared schema. This deliverable describes the resulting specification: the foundingGIDE search input RO-Crate profile (v0.2, January 2026), which defines a minimal interoperability metadata set as a profile of the RO-Crate community standard, together with a companion JSON-LD context that defines profile's terms in schema.org, Bioschemas, Darwin Core and OBO Foundry vocabularies. The profile is built directly on the twelve commonly-held metadata components identified in Deliverable D6.1, and adopts a two-tier structure: a small core of mandatory fields that drives cross-resource search, and an extended REMBI-aligned layer that supports richer expression for resource-specific metadata.
