Last Updated

Alignment
EC Call for Proposals template v2.5
Source Schema
docs/schemas/arkid_funding_schema.json
Highlights
- Keeps the opportunity-search friendly fields (summary, eligibility, keywords) from earlier ArkID releases.
- Embeds EC Proposal v2.5 payloads under arkid_extensions.ec_proposal for downstream submission tooling.
- Links all critical enums (actionType, partnershipName, RIS flags) to the shared reference catalogue.
When to Use
- Publishing new calls to the ArkID discovery API and public catalogue.
- Synchronising EC Funding & Tenders data into ArkID while preserving downstream compatibility.
- Seeding knowledge-graph relationships between funding opportunities, organisations, and projects.
Core Identification
Minimal surface required to publish a funding opportunity.
opportunity_id
stringRequiredStable ArkID/EC identifier for the call (maps to ARKF reference in linked records).
title
stringRequiredPublic-facing call title displayed across ArkID experiences.
funding_type
string (enum)RequiredGrant, fellowship, procurement, or other funding category.
applicant_type
string (enum)RequiredPrimary applicant persona (research institution, SME, consortium, etc.).
opportunity_url
string (uri)RequiredCanonical landing page for deeper details or submissions.
Lifecycle & Funding Signals
Important dates, amounts, and eligibility information for applicant planning.
application_open_date / application_deadline
string (date)RecommendedWindow for submissions; align with EC call deadlines when available.

EC Proposal Alignment
Full fidelity copy of the EC call headers stored under arkid_extensions.
- arkid_extensions.ec_template_version tracks the upstream EC version used when ingesting the call.
- ec_proposal.acronym, abstract, call_id, and call_deadline_date mirror the official proposal document.
- partnership_name, partnership_type, action_type, eit_area, and RIS flags reuse reference catalogue enums.
- fixed_keywords and free_keywords keep both taxonomy IDs and human-friendly descriptors.
